66-479: Apple Intelligence is an artificial intelligence developed by Apple Inc. Relying on a combination of on-device and server processing, it was announced on June 10, 2024, at WWDC 2024 , as a built-in feature of Apple's iOS 18 , iPadOS 18 , and macOS Sequoia operating systems, which were announced alongside Apple Intelligence. Apple Intelligence is free for all users with supported devices. It launched for developers and testers on July 29, 2024, in U.S. English, with

132-581: A loss function . Variants of gradient descent are commonly used to train neural networks. Another type of local search is evolutionary computation , which aims to iteratively improve a set of candidate solutions by "mutating" and "recombining" them, selecting only the fittest to survive each generation. Distributed search processes can coordinate via swarm intelligence algorithms. Two popular swarm algorithms used in search are particle swarm optimization (inspired by bird flocking ) and ant colony optimization (inspired by ant trails ). Formal logic

198-475: A "degree of truth" between 0 and 1. It can therefore handle propositions that are vague and partially true. Non-monotonic logics , including logic programming with negation as failure , are designed to handle default reasoning . Other specialized versions of logic have been developed to describe many complex domains. Many problems in AI (including in reasoning, planning, learning, perception, and robotics) require

264-468: A built-in RSS reader. It also introduced IMAP IDLE support for account inboxes. Mac OS X Snow Leopard (version 10.6) brought Microsoft Exchange Server 2007 support. In Mac OS X Lion (version 10.7), Mail featured a redesigned iPad -like user interface with full-screen capabilities, an updated message search interface, support for Microsoft Exchange Server 2010 and Yahoo! Mail (via IMAP). Also added

330-437: A cloud model running on servers primarily using Apple silicon . Both models consist of a generic foundation model, as well as multiple adapter models that are more specialized to particular tasks like text summarization and tone adjustment. According to a human evaluation done by Apple's machine learning division, the on-device foundation model beat or tied equivalent small models by Mistral AI , Microsoft , and Google , while

396-460: A contradiction from premises that include the negation of the problem to be solved. Inference in both Horn clause logic and first-order logic is undecidable , and therefore intractable . However, backward reasoning with Horn clauses, which underpins computation in the logic programming language Prolog , is Turing complete . Moreover, its efficiency is competitive with computation in other symbolic programming languages. Fuzzy logic assigns

462-448: A link in the message instead of the whole file). In OS X El Capitan (version 10.11), a filter was added to the message list to filter by various options such as Unread, Flagged, or messages with attachments. The conversation display was also redesigned and various disk space saving optimizations were implemented. Streaming notification support for Exchange accounts was also added. In macOS 10.13 ( High Sierra ) Mail reached version 11.5,

528-442: A mobile version of Mail with added Exchange ActiveSync (EAS) support, though it notoriously missed the functionality of attaching files to reply emails until the release of iOS 9 . EAS is not supported in the macOS version of Apple's Mail app, the main issue being that sent messages will incorrectly be duplicated in the sent messages folder, which then propagates via sync to all other devices including iOS. Features of Mail include

594-645: A movie with a narrative arc based on identified themes. Additionally, users can search for specific photos or videos by description and/or keyword, and Apple Intelligence can pinpoint particular moments within video clips. Using the Notification Summary feature, Apple Intelligence can summarize notifications from messaging apps and groups of notifications from apps so that users don't have to examine large amounts of notifications. A new Reduce Interruptions focus mode silences notifications deemed unimportant while letting important notifications go through. As

660-429: A path to a target goal, a process called means-ends analysis . Simple exhaustive searches are rarely sufficient for most real-world problems: the search space (the number of places to search) quickly grows to astronomical numbers . The result is a search that is too slow or never completes. " Heuristics " or "rules of thumb" can help prioritize choices that are more likely to reach a goal. Adversarial search

726-468: A proprietary single-message-per-file format (with the filename extension .emlx ) to permit indexing by Spotlight . Additional features were: The new version also changed the UI for the buttons in the toolbar. Whereas previous buttons had free-standing defined shapes, the new buttons featured shapes within a lozenge -shaped capsule. According to many users, and even Apple's own human interface guidelines at

792-481: A result of the company's partnership with OpenAI , Apple Intelligence also includes a system-wide integration with ChatGPT, allowing Siri to determine when to send certain complex user requests to ChatGPT. This system-wide integration is powered by GPT-4o . ChatGPT integration is opt-in by default, with users being prompted before any data or photos are sent to ChatGPT servers and IP addresses being obscured when requests are sent to OpenAI's servers. Using ChatGPT features

858-544: A significantly redeveloped Siri. In an earnings call in February 2024, Cook stated that the company was spending a "tremendous amount of time and effort" into AI features that would be shared "later that year". All Macs and iPads with an M-series Apple silicon chip will support Apple Intelligence with the release of macOS Sequoia and iPadOS 18 . iPhones and iPads with the A17 Pro chip or later will also be supported with

924-405: A text-based user interface ( TUI ) to allow for backwards compatibility. When Apple began to adapt NeXTSTEP to become Mac OS X , both the operating system and the application went through various stages as it was developed. In a beta version (codenamed " Rhapsody ") and various other early pre-releases of Mac OS X, Mail was known as MailViewer. However, with the third developer release of Mac OS X,

990-726: A tool that can be used for reasoning (using the Bayesian inference algorithm), learning (using the expectation–maximization algorithm ), planning (using decision networks ) and perception (using dynamic Bayesian networks ). Probabilistic algorithms can also be used for filtering, prediction, smoothing, and finding explanations for streams of data, thus helping perception systems analyze processes that occur over time (e.g., hidden Markov models or Kalman filters ). The simplest AI applications can be divided into two types: classifiers (e.g., "if shiny then diamond"), on one hand, and controllers (e.g., "if diamond then pick up"), on

1056-548: A user's IP address and being notified of whether they have read an email. Extensions from the Mac App Store can now integrate with the Mail app, and iCloud+ subscribers can easily create a new email address that forwards to their primary address. Mail has been updated to include features from popular competitors, such as allowing a user to undo sending an email for up to 10, 20, or 30 seconds, scheduling an email to be sent at

1122-404: A user-set time, reminding the user to follow up to an email, and notifying the user to add an attachment or recipient if they seemed to forget to do themselves. Search has been improved by using synonyms for search terms and automatically correcting typos. It also shows shared content and previous search terms when invoked. Messages you sent which haven't received a reply will also move to the top of

1188-473: A version that was not further upgraded (in High Sierra, at least until 2021). Support for macOS's new " dark mode " was added to Mail. Added support for Block Sender, Unsubscribe, Mute Thread and layout options. In macOS Big Sur , Mail was updated alongside the other first-party apps to feature the new design language of Big Sur, with a full-height sidebar and updated icons that match the blue color of

1254-669: A wide range of techniques, including search and mathematical optimization , formal logic , artificial neural networks , and methods based on statistics , operations research , and economics . AI also draws upon psychology , linguistics , philosophy , neuroscience , and other fields. Artificial intelligence was founded as an academic discipline in 1956, and the field went through multiple cycles of optimism, followed by periods of disappointment and loss of funding, known as AI winter . Funding and interest vastly increased after 2012 when deep learning outperformed previous AI techniques. This growth accelerated further after 2017 with

1320-490: A wide variety of techniques to accomplish the goals above. AI can solve many problems by intelligently searching through many possible solutions. There are two very different kinds of search used in AI: state space search and local search . State space search searches through a tree of possible states to try to find a goal state. For example, planning algorithms search through trees of goals and subgoals, attempting to find

1386-641: Is a body of knowledge represented in a form that can be used by a program. An ontology is the set of objects, relations, concepts, and properties used by a particular domain of knowledge. Knowledge bases need to represent things such as objects, properties, categories, and relations between objects; situations, events, states, and time; causes and effects; knowledge about knowledge (what we know about what other people know); default reasoning (things that humans assume are true until they are told differently and will remain true even when other facts are changing); and many other aspects and domains of knowledge. Among

1452-459: Is an input, at least one hidden layer of nodes and an output. Each node applies a function and once the weight crosses its specified threshold, the data is transmitted to the next layer. A network is typically called a deep neural network if it has at least 2 hidden layers. Learning algorithms for neural networks use local search to choose the weights that will get the right output for each input during training. The most common training technique

1518-462: Is an interdisciplinary umbrella that comprises systems that recognize, interpret, process, or simulate human feeling, emotion, and mood . For example, some virtual assistants are programmed to speak conversationally or even to banter humorously; it makes them appear more sensitive to the emotional dynamics of human interaction, or to otherwise facilitate human–computer interaction . However, this tends to give naïve users an unrealistic conception of

1584-444: Is an unsolved problem. Knowledge representation and knowledge engineering allow AI programs to answer questions intelligently and make deductions about real-world facts. Formal knowledge representations are used in content-based indexing and retrieval, scene interpretation, clinical decision support, knowledge discovery (mining "interesting" and actionable inferences from large databases ), and other areas. A knowledge base

1650-422: Is anything that perceives and takes actions in the world. A rational agent has goals or preferences and takes actions to make them happen. In automated planning , the agent has a specific goal. In automated decision-making , the agent has preferences—there are some situations it would prefer to be in, and some situations it is trying to avoid. The decision-making agent assigns a number to each situation (called

1716-413: Is classified based on previous experience. There are many kinds of classifiers in use. The decision tree is the simplest and most widely used symbolic machine learning algorithm. K-nearest neighbor algorithm was the most widely used analogical AI until the mid-1990s, and Kernel methods such as the support vector machine (SVM) displaced k-nearest neighbor in the 1990s. The naive Bayes classifier

1782-440: Is free for all users without needing to sign in, however, they will only get a limited number of GPT-4o requests until switching to a less powerful GPT. Paid subscribers can sign in to gain access to paid features systemwide including more requests using GPT-4o. Apple plans to integrate other models such as Google's Gemini into the system in the future. Apple first implemented artificial intelligence features in its products with

1848-413: Is labelled by a solution of the problem and whose leaf nodes are labelled by premises or axioms . In the case of Horn clauses , problem-solving search can be performed by reasoning forwards from the premises or backwards from the problem. In the more general case of the clausal form of first-order logic , resolution is a single, axiom-free rule of inference, in which a problem is solved by proving

1914-400: Is reportedly the "most widely used learner" at Google, due in part to its scalability. Neural networks are also used as classifiers. An artificial neural network is based on a collection of nodes also known as artificial neurons , which loosely model the neurons in a biological brain. It is trained to recognise patterns; once trained, it can recognise those patterns in fresh data. There

1980-583: Is the backpropagation algorithm. Neural networks learn to model complex relationships between inputs and outputs and find patterns in data. In theory, a neural network can learn any function. Apple Mail The current version of Mail utilizes SMTP for message sending, POP3 , Exchange and IMAP for message retrieval and S/MIME for end-to-end message encryption. It is also preconfigured to work with popular email providers , such as Yahoo! Mail , AOL Mail , Gmail , Outlook and iCloud (formerly MobileMe ) and it supports Exchange . iOS features

2046-404: Is the process of proving a new statement ( conclusion ) from other statements that are given and assumed to be true (the premises ). Proofs can be structured as proof trees , in which nodes are labelled by sentences, and children nodes are connected to parent nodes by inference rules . Given a problem and a set of premises, problem-solving reduces to searching for a proof tree whose root node

2112-440: Is used for game-playing programs, such as chess or Go. It searches through a tree of possible moves and counter-moves, looking for a winning position. Local search uses mathematical optimization to find a solution to a problem. It begins with some form of guess and refines it incrementally. Gradient descent is a type of local search that optimizes a set of numerical parameters by incrementally adjusting them to minimize

2178-455: Is used for reasoning and knowledge representation . Formal logic comes in two main forms: propositional logic (which operates on statements that are true or false and uses logical connectives such as "and", "or", "not" and "implies") and predicate logic (which also operates on objects, predicates and relations and uses quantifiers such as " Every X is a Y " and "There are some X s that are Y s"). Deductive reasoning in logic

2244-436: Is used in AI programs that make decisions that involve other agents. Machine learning is the study of programs that can improve their performance on a given task automatically. It has been a part of AI from the beginning. There are several kinds of machine learning. Unsupervised learning analyzes a stream of data and finds patterns and makes predictions without any other guidance. Supervised learning requires labeling

2310-905: Is when the knowledge gained from one problem is applied to a new problem. Deep learning is a type of machine learning that runs inputs through biologically inspired artificial neural networks for all of these types of learning. Computational learning theory can assess learners by computational complexity , by sample complexity (how much data is required), or by other notions of optimization . Natural language processing (NLP) allows programs to read, write and communicate in human languages such as English . Specific problems include speech recognition , speech synthesis , machine translation , information extraction , information retrieval and question answering . Early work, based on Noam Chomsky 's generative grammar and semantic networks , had difficulty with word-sense disambiguation unless restricted to small domains called " micro-worlds " (due to

2376-1364: The Image Playground app. Similarly to OpenAI's DALL-E , it can be used to generate images using AI, using phrases and descriptions to create an image with customizable styles such as Animation and Sketch. In Notes, users can access Image Playground on iPad and iPhone through the Image Wand tool in the Apple Pencil palette without having to open the Image Playground app. Rough sketches made with Apple Pencil can be transformed into images. Using Apple Intelligence text-to-image models , users can create original " Genmoji" images by typing descriptions. Users can pick people in photos and create Genmoji images that resemble them. Similarly to emoji , Genmoji can be added inline to text messages, tapbacks, stickers and can be shared in Messages as well in third-party applications as inline messages or as stickers. Siri , Apple's virtual assistant, has been updated with enhanced capabilities made possible by Apple Intelligence. The latest iteration features an updated user interface, improved natural language processing, and

2442-520: The bar exam , SAT test, GRE test, and many other real-world applications. Machine perception is the ability to use input from sensors (such as cameras, microphones, wireless signals, active lidar , sonar, radar, and tactile sensors ) to deduce aspects of the world. Computer vision is the ability to analyze visual input. The field includes speech recognition , image classification , facial recognition , object recognition , object tracking , and robotic perception . Affective computing

2508-531: The iPhone 8 and the iPhone X with the A11 Bionic processor, which featured its first dedicated Neural Engine for accelerating common machine learning tasks. Despite its investments in artificial intelligence, Siri was criticized both by reviewers and internally at Apple for lagging behind other AI assistants. The rapid development of generative artificial intelligence and the release of ChatGPT in late 2022 reportedly blindsided Apple executives and forced

2574-416: The transformer architecture , and by the early 2020s hundreds of billions of dollars were being invested in AI (known as the " AI boom "). The widespread use of AI in the 21st century exposed several unintended consequences and harms in the present and raised concerns about its risks and long-term effects in the future, prompting discussions about regulatory policies to ensure the safety and benefits of

2640-436: The " utility ") that measures how much the agent prefers it. For each possible action, it can calculate the " expected utility ": the utility of all possible outcomes of the action, weighted by the probability that the outcome will occur. It can then choose the action with the maximum expected utility. In classical planning , the agent knows exactly what the effect of any action will be. In most real-world problems, however,

2706-574: The ability to configure the software to receive all of a user's email accounts in the one list, ability to file emails into folders, ability to search for emails, and ability to automatically append signatures to outgoing emails. It also integrates with the Contacts list, Calendar, Maps and other apps. Mail was originally developed by NeXT as NeXTMail, the email application for its NeXTSTEP operating system. It supported rich text formatting with images and voice messaging, and MIME emails. It also supported

2772-421: The agent can seek information to improve its preferences. Information value theory can be used to weigh the value of exploratory or experimental actions. The space of possible future actions and situations is typically intractably large, so the agents must take actions and evaluate situations while being uncertain of what the outcome will be. A Markov decision process has a transition model that describes

2838-510: The agent may not be certain about the situation they are in (it is "unknown" or "unobservable") and it may not know for certain what will happen after each possible action (it is not "deterministic"). It must choose an action by making a probabilistic guess and then reassess the situation to see if the action worked. In some problems, the agent's preferences may be uncertain, especially if there are other agents or humans involved. These can be learned (e.g., with inverse reinforcement learning ), or

2904-529: The agent to operate with incomplete or uncertain information. AI researchers have devised a number of tools to solve these problems using methods from probability theory and economics. Precise mathematical tools have been developed that analyze how an agent can make choices and plan, using decision theory , decision analysis , and information value theory . These tools include models such as Markov decision processes , dynamic decision networks , game theory and mechanism design . Bayesian networks are

2970-527: The app's icon. The Mail app icon was changed to be more consistent with the iOS version, depicting a white envelope on a blue background, albeit with a more "3D" look that has the text "Apple Park California 95014" subtly etched on the envelope. Mail now also supports interactive notifications and integrates with the Reminders app to let Siri suggest possible reminders based on who you are emailing. Mail now has an option to block trackers in emails from viewing

3036-493: The application had returned to being known simply as Mail. Mail was included in all versions of macOS up to and including Mac OS X Panther , which was released on October 24, 2003. It was integrated with other Apple applications such as Address Book , iChat , and iCal . Some of its features that remain in the most recent version of Mail include rules for mailboxes, junk mail filtering and multiple account management. In Mac OS X Tiger (version 10.4), Mail version 2 included

3102-648: The common sense knowledge problem ). Margaret Masterman believed that it was meaning and not grammar that was the key to understanding languages, and that thesauri and not dictionaries should be the basis of computational language structure. Modern deep learning techniques for NLP include word embedding (representing words, typically as vectors encoding their meaning), transformers (a deep learning architecture using an attention mechanism), and others. In 2019, generative pre-trained transformer (or "GPT") language models began to generate coherent text, and by 2023, these models were able to get human-level scores on

3168-527: The company to refocus its efforts on AI. In an interview with Good Morning America , Apple CEO Tim Cook stated that generative AI had "great promise" but had some potential dangers, and that it was "looking closely" at ChatGPT. It was first reported in July 2023 that Apple was creating its own internal large language model, codenamed "Ajax". In October 2023, Apple was reportedly on track to release generative AI features into its operating systems by 2024, including

3234-535: The email. Apple's Photos app includes a feature to create custom memory movies and enhanced search capabilities. Users can describe a story, and using Apple Intelligence, selects matching photos, videos, and music. Users can also remove distractions in images with the Clean Up tool in the Photos app. Apple Intelligence identifies background objects and removes them with a tap, brush, or circle. It organizes these into

3300-536: The iOS 18.1, macOS 15.1, and iPadOS 18.1 developer betas, released partially in October 2024, and will fully launch by 2025. UK, Australia, Canada, New Zealand, and South African localized versions of English will have support by the end of 2024, while Chinese, English (India), English (Singapore), French, German, Italian, Japanese, Korean, Portuguese, Spanish, and Vietnamese will be added over the course of 2025. Apple Intelligence consists of an on-device model as well as

3366-440: The intelligence of existing computer agents. Moderate successes related to affective computing include textual sentiment analysis and, more recently, multimodal sentiment analysis , wherein AI classifies the affects displayed by a videotaped subject. A machine with artificial general intelligence should be able to solve a wide variety of problems with breadth and versatility similar to human intelligence . AI research uses

3432-537: The late 1980s and 1990s, methods were developed for dealing with uncertain or incomplete information, employing concepts from probability and economics . Many of these algorithms are insufficient for solving large reasoning problems because they experience a "combinatorial explosion": They become exponentially slower as the problems grow. Even humans rarely use the step-by-step deduction that early AI research could model. They solve most of their problems using fast, intuitive judgments. Accurate and efficient reasoning

3498-457: The most difficult problems in knowledge representation are the breadth of commonsense knowledge (the set of atomic facts that the average person knows is enormous); and the sub-symbolic form of most commonsense knowledge (much of what people know is not represented as "facts" or "statements" that they could express verbally). There is also the difficulty of knowledge acquisition , the problem of obtaining knowledge for AI applications. An "agent"

3564-596: The option to interact via text by double tapping the home bar without enabling the feature in the Accessibility menu, or double-clicking the command key on macOS. In a later update, Apple Intelligence will add the ability for Siri to use personal context from device activities to answer queries. Apple Intelligence adds a feature called Priority Messages to the Mail app, which shows urgent emails such as same-day invitations or boarding passes, with AI generated summaries of

3630-405: The other hand. Classifiers are functions that use pattern matching to determine the closest match. They can be fine-tuned based on chosen examples using supervised learning . Each pattern (also called an " observation ") is labeled with a certain predefined class. All the observations combined with their class labels are known as a data set . When a new observation is received, that observation

3696-411: The probability that a particular action will change the state in a particular way and a reward function that supplies the utility of each state and the cost of each action. A policy associates a decision with each possible state. The policy could be calculated (e.g., by iteration ), be heuristic , or it can be learned. Game theory describes the rational behavior of multiple interacting agents and

3762-1454: The release of iOS 18 . Analyst Ming-Chi Kuo speculates that the RAM requirements of the on-device model prohibits Apple Intelligence from running on older iPhone models. Artificial intelligence Artificial intelligence ( AI ), in its broadest sense, is intelligence exhibited by machines , particularly computer systems . It is a field of research in computer science that develops and studies methods and software that enable machines to perceive their environment and use learning and intelligence to take actions that maximize their chances of achieving defined goals. Such machines may be called AIs. Some high-profile applications of AI include advanced web search engines (e.g., Google Search ); recommendation systems (used by YouTube , Amazon , and Netflix ); interacting via human speech (e.g., Google Assistant , Siri , and Alexa ); autonomous vehicles (e.g., Waymo ); generative and creative tools (e.g., ChatGPT , and AI art ); and superhuman play and analysis in strategy games (e.g., chess and Go ). However, many AI applications are not perceived as AI: "A lot of cutting edge AI has filtered into general applications, often without being called AI because once something becomes useful enough and common enough it's not labeled AI anymore ." The various subfields of AI research are centered around particular goals and

3828-561: The release of Siri in the iPhone 4S in 2011. In the years after its release, Apple engaged in efforts to ensure its artificial intelligence operations remained covert; according to University of California, Berkeley professor Trevor Darrell , the company's secrecy deterred graduate students. The company started expanding its artificial intelligence team in 2015, opening up its operations by publishing more scientific papers and joining AI industry research groups. Apple reportedly acquired more AI companies from 2016 to 2020. In 2017, Apple released

3894-499: The server foundation models beat the performance of OpenAI 's GPT-3 , while roughly matching the performance of GPT-4 . Apple's cloud models are built on a Private Cloud Compute platform which is designed heavily with user privacy and end-to-end encryption in mind. Unlike other generative AI services like ChatGPT which use servers from third-parties, Apple Intelligence's cloud models are run entirely on Apple servers with custom Apple silicon hardware built for end-to-end encryption. It

3960-471: The technology . The general problem of simulating (or creating) intelligence has been broken into subproblems. These consist of particular traits or capabilities that researchers expect an intelligent system to display. The traits described below have received the most attention and cover the scope of AI research. Early researchers developed algorithms that imitated step-by-step reasoning that humans use when they solve puzzles or make logical deductions . By

In reinforcement learning , the agent is rewarded for good responses and punished for bad ones. The agent learns to choose responses that are classified as "good". Transfer learning

4158-420: The use of particular tools. The traditional goals of AI research include reasoning , knowledge representation , planning , learning , natural language processing , perception, and support for robotics . General intelligence —the ability to complete any task performable by a human on an at least equal level—is among the field's long-term goals. To reach these goals, AI researchers have adapted and integrated

4224-733: Was also designed to make sure that the software running on said servers matches the independently verifiable software accessible to researchers. In case of a software mismatch, Apple devices will refuse to connect to the servers. Apple Intelligence features writing tools that are powered by AI, including Rewrite, and Proofread. These features help enhance users' writing to make it more friendly, concise or professional, similar to Grammarly 's AI writing features. It can also be used to generate summaries , key points, tables , and lists from an article or piece of writing. GPT-4o will be available as an optional integrated part of Writing Tools. Apple Intelligence can be used to generate images on-device with

4290-474: Was split off into a stand-alone application. The RSS reader and to-dos were discontinued. In OS X Mavericks (version 10.9), Mail ceased support for plain-text MIME multipart/alternative messages and solely retained the HTML or rich-text version. In OS X Yosemite (version 10.10), Mail introduced Markup (inline annotation of PDF or image files) and Mail Drop (automatically uploads attachments to iCloud, and sends

4356-474: Was the capability to group messages by subject in a similar fashion to Mail on iOS 4 . The bounce function, where unwanted emails could be bounced back to the sender, was dropped, as was support for Exchange push email. In OS X Mountain Lion (version 10.8), Mail received VIP tagging, Safari -style inline search for words within an email message, the ability to sync with iCloud and new sharing features. Notes
