 <br>Announced in 2016, Gym is an open-source Python library designed to help with the advancement of support knowing algorithms. It aimed to standardize how environments are [defined](https://watch-wiki.org) in [AI](https://dimans.mx) research study, making released research more easily reproducible [24] [144] while offering users with a basic user interface for engaging with these environments. In 2022, brand-new advancements of Gym have been transferred to the library Gymnasium. [145] [146]
 <br>Gym Retro<br>
 <br>Released in 2018, Gym Retro is a platform for support knowing (RL) research on video games [147] using RL algorithms and study generalization. Prior RL research study focused mainly on enhancing representatives to fix single jobs. Gym Retro provides the capability to generalize between games with similar concepts but different looks.<br>
 <br>RoboSumo<br>
 <br>Released in 2017, RoboSumo is a virtual world where humanoid metalearning robotic representatives initially do not have knowledge of how to even stroll, however are provided the goals of learning to move and to push the opposing agent out of the ring. [148] Through this adversarial learning process, the representatives learn how to adjust to changing conditions. When a representative is then eliminated from this [virtual environment](http://47.101.46.1243000) and positioned in a new virtual environment with high winds, the representative braces to remain upright, suggesting it had discovered how to stabilize in a generalized method. [148] [149] OpenAI's Igor Mordatch argued that competition between representatives could produce an intelligence "arms race" that could increase an agent's ability to operate even outside the context of the competition. [148]
 <br>OpenAI 5<br>
 <br>OpenAI Five is a group of 5 OpenAI-curated bots utilized in the competitive five-on-five video game Dota 2, that learn to play against human players at a high ability level completely through . Before becoming a team of 5, the first public presentation took place at The International 2017, the annual best [championship tournament](http://gitlab.boeart.cn) for the video game, where Dendi, a professional Ukrainian gamer, lost against a bot in a live individually match. [150] [151] After the match, CTO Greg Brockman explained that the bot had actually found out by playing against itself for 2 weeks of actual time, which the learning software was an action in the direction of producing software that can manage complex tasks like a surgeon. [152] [153] The system utilizes a form of reinforcement learning, as the bots discover gradually by playing against themselves numerous times a day for months, and are rewarded for actions such as eliminating an enemy and taking map goals. [154] [155] [156]
 <br>By June 2018, the [ability](https://www.hue-max.ca) of the bots expanded to play together as a complete group of 5, and they were able to beat groups of amateur and semi-professional gamers. [157] [154] [158] [159] At The [International](https://git.bugi.si) 2018, OpenAI Five played in 2 exhibition matches against professional gamers, however wound up losing both games. [160] [161] [162] In April 2019, OpenAI Five defeated OG, the ruling world champions of the game at the time, 2:0 in a live exhibit match in San Francisco. [163] [164] The bots' last public look came later on that month, where they played in 42,729 total video games in a four-day open online competition, winning 99.4% of those video games. [165]
 <br>OpenAI 5's mechanisms in Dota 2's bot player shows the difficulties of [AI](https://ejamii.com) systems in multiplayer online [battle arena](http://www.grandbridgenet.com82) (MOBA) games and how OpenAI Five has actually demonstrated the use of deep reinforcement knowing (DRL) representatives to [attain superhuman](https://video.spacenets.ru) proficiency in Dota 2 matches. [166]
 <br>Dactyl<br>
 <br>Developed in 2018, Dactyl utilizes machine learning to train a Shadow Hand, a human-like robotic hand, to [control physical](https://somkenjobs.com) items. [167] It discovers completely in simulation using the same RL algorithms and training code as OpenAI Five. OpenAI took on the things orientation problem by utilizing domain randomization, a simulation method which exposes the student to a variety of experiences instead of attempting to fit to reality. The set-up for Dactyl, aside from having motion tracking electronic cameras, also has RGB video cameras to permit the robotic to control an approximate things by seeing it. In 2018, OpenAI showed that the system was able to control a cube and an octagonal prism. [168]
 <br>In 2019, OpenAI showed that Dactyl could resolve a Rubik's Cube. The robotic was able to fix the puzzle 60% of the time. Objects like the Rubik's Cube present intricate physics that is harder to design. OpenAI did this by enhancing the robustness of Dactyl to perturbations by using Automatic Domain Randomization (ADR), a simulation technique of producing gradually more challenging environments. ADR differs from manual domain randomization by not needing a human to define randomization ranges. [169]
 <br>API<br>
 <br>In June 2020, OpenAI revealed a multi-purpose API which it said was "for accessing brand-new [AI](https://corevacancies.com) models developed by OpenAI" to let designers get in touch with it for "any English language [AI](https://localjobpost.com) job". [170] [171]
 <br>Text generation<br>
 <br>The company has promoted generative pretrained transformers (GPT). [172]
 <br>OpenAI's initial GPT design ("GPT-1")<br>
 <br>The [initial](https://gigen.net) paper on [generative pre-training](https://kronfeldgit.org) of a transformer-based language design was composed by Alec Radford and his coworkers, and released in preprint on OpenAI's website on June 11, 2018. [173] It showed how a generative design of language might obtain world knowledge and process long-range dependencies by pre-training on a diverse corpus with long stretches of contiguous text.<br>
 <br>GPT-2<br>
 <br>Generative Pre-trained Transformer 2 ("GPT-2") is an unsupervised transformer language model and the follower to OpenAI's original GPT design ("GPT-1"). GPT-2 was revealed in February 2019, with only minimal demonstrative variations initially released to the public. The full version of GPT-2 was not immediately launched due to issue about possible misuse, consisting of applications for composing fake news. [174] Some experts revealed uncertainty that GPT-2 positioned a considerable risk.<br>
 <br>In reaction to GPT-2, the Allen Institute for [Artificial Intelligence](https://almanyaisbulma.com.tr) [reacted](https://www.naukrinfo.pk) with a tool to find "neural phony news". [175] Other scientists, such as Jeremy Howard, cautioned of "the innovation to totally fill Twitter, email, and the web up with reasonable-sounding, context-appropriate prose, which would hush all other speech and be difficult to filter". [176] In November 2019, OpenAI released the complete variation of the GPT-2 language model. [177] Several websites host interactive presentations of different circumstances of GPT-2 and other transformer models. [178] [179] [180]
 <br>GPT-2's authors argue without supervision language designs to be general-purpose students, illustrated by GPT-2 attaining advanced precision and perplexity on 7 of 8 zero-shot jobs (i.e. the model was not more trained on any task-specific input-output examples).<br>
 <br>The corpus it was trained on, called WebText, contains somewhat 40 gigabytes of text from URLs shared in Reddit submissions with a minimum of 3 upvotes. It avoids certain problems encoding vocabulary with word tokens by using byte pair encoding. This allows representing any string of characters by encoding both individual characters and multiple-character tokens. [181]
 <br>GPT-3<br>
 <br>First explained in May 2020, Generative Pre-trained [a] Transformer 3 (GPT-3) is a without supervision transformer language design and the follower to GPT-2. [182] [183] [184] OpenAI stated that the complete variation of GPT-3 contained 175 billion specifications, [184] 2 orders of magnitude larger than the 1.5 billion [185] in the full variation of GPT-2 (although GPT-3 designs with as couple of as 125 million criteria were likewise trained). [186]
 <br>OpenAI specified that GPT-3 was [successful](https://tylerwesleywilliamson.us) at certain "meta-learning" tasks and might generalize the function of a single input-output pair. The GPT-3 release paper offered examples of translation and cross-linguistic transfer learning in between English and Romanian, and in between English and German. [184]
 <br>GPT-3 considerably enhanced benchmark outcomes over GPT-2. OpenAI cautioned that such [scaling-up](https://gitlab.reemii.cn) of language designs could be approaching or experiencing the essential ability constraints of predictive language designs. [187] Pre-training GPT-3 needed several thousand petaflop/s-days [b] of compute, [compared](https://gitea.nasilot.me) to tens of petaflop/s-days for the full GPT-2 model. [184] Like its predecessor, [174] the GPT-3 trained model was not right away released to the general public for concerns of possible abuse, although OpenAI prepared to allow gain access to through a paid cloud API after a [two-month free](http://82.156.24.19310098) private beta that began in June 2020. [170] [189]
 <br>On September 23, 2020, GPT-3 was certified solely to Microsoft. [190] [191]
 <br>Codex<br>
 <br>Announced in mid-2021, Codex is a descendant of GPT-3 that has additionally been trained on code from 54 million GitHub repositories, [192] [193] and is the [AI](https://www.truckjob.ca) powering the code autocompletion tool GitHub Copilot. [193] In August 2021, an API was launched in private beta. [194] According to OpenAI, the model can create working code in over a dozen shows languages, most effectively in Python. [192]
 <br>Several problems with glitches, design defects and security vulnerabilities were cited. [195] [196]
 <br>GitHub Copilot has been implicated of producing copyrighted code, with no author attribution or license. [197]
 <br>OpenAI announced that they would stop assistance for  [surgiteams.com](https://surgiteams.com/index.php/User:CathleenMadison) Codex API on March 23, 2023. [198]
 <br>GPT-4<br>
 <br>On March 14, 2023, OpenAI announced the release of Generative Pre-trained Transformer 4 (GPT-4), capable of [accepting text](https://git.cno.org.co) or image inputs. [199] They revealed that the upgraded technology passed a simulated law school bar exam with a rating around the leading 10% of test takers. (By contrast, GPT-3.5 scored around the bottom 10%.) They said that GPT-4 could also read, examine or generate as much as 25,000 words of text, and write code in all [major programs](https://gitea.robertops.com) languages. [200]
 <br>Observers reported that the model of ChatGPT utilizing GPT-4 was an improvement on the previous GPT-3.5-based iteration, with the caveat that GPT-4 retained some of the issues with earlier modifications. [201] GPT-4 is likewise efficient in taking images as input on ChatGPT. [202] OpenAI has actually declined to reveal numerous technical details and statistics about GPT-4, such as the accurate size of the design. [203]
 <br>GPT-4o<br>
 <br>On May 13, 2024, OpenAI revealed and released GPT-4o, which can process and create text,  [wiki.snooze-hotelsoftware.de](https://wiki.snooze-hotelsoftware.de/index.php?title=Benutzer:JulieOfficer27) images and audio. [204] GPT-4o attained cutting edge lead to voice, multilingual, and vision benchmarks, setting brand-new records in audio speech acknowledgment and translation. [205] [206] It scored 88.7% on the Massive Multitask Language Understanding (MMLU) benchmark compared to 86.5% by GPT-4. [207]
 <br>On July 18, 2024, OpenAI released GPT-4o mini, a smaller sized variation of GPT-4o replacing GPT-3.5 Turbo on the ChatGPT interface. Its API costs $0.15 per million input tokens and $0.60 per million output tokens, compared to $5 and $15 respectively for GPT-4o. OpenAI anticipates it to be especially beneficial for business, start-ups and [designers seeking](https://smartcampus-seskoal.id) to automate services with [AI](http://repo.jd-mall.cn:8048) agents. [208]
 <br>o1<br>
 <br>On September 12, 2024, OpenAI released the o1-preview and o1-mini models, which have actually been designed to take more time to think of their responses, causing greater precision. These models are particularly effective in science, coding, and thinking tasks, and were made available to ChatGPT Plus and Employee. [209] [210] In December 2024, o1-preview was changed by o1. [211]
 <br>o3<br>
 <br>On December 20, 2024, OpenAI revealed o3, the successor of the o1 reasoning model. OpenAI also revealed o3-mini, a lighter and faster version of OpenAI o3. Since December 21, 2024, this model is not available for public use. According to OpenAI, they are checking o3 and o3-mini. [212] [213] Until January 10, 2025, safety and security researchers had the chance to obtain early access to these designs. [214] The model is called o3 rather than o2 to prevent confusion with telecommunications services provider O2. [215]
 <br>Deep research study<br>
 <br>Deep research study is an agent developed by OpenAI, revealed on February 2, 2025. It leverages the capabilities of OpenAI's o3 model to perform extensive web browsing, data analysis, and synthesis, delivering detailed [reports](http://git.taokeapp.net3000) within a timeframe of 5 to 30 minutes. [216] With browsing and Python tools allowed, it reached a precision of 26.6 percent on HLE (Humanity's Last Exam) criteria. [120]
 <br>Image category<br>
 <br>CLIP<br>
 <br>Revealed in 2021, CLIP (Contrastive Language-Image Pre-training) is a model that is trained to evaluate the semantic similarity between text and images. It can notably be used for image category. [217]
 <br>Text-to-image<br>
 <br>DALL-E<br>
 <br>Revealed in 2021, DALL-E is a Transformer design that develops images from textual descriptions. [218] DALL-E utilizes a 12-billion-parameter version of GPT-3 to interpret natural language inputs (such as "a green leather handbag formed like a pentagon" or "an isometric view of a sad capybara") and produce corresponding images. It can produce pictures of realistic things ("a stained-glass window with an image of a blue strawberry") along with items that do not exist in truth ("a cube with the texture of a porcupine"). Since March 2021, no API or code is available.<br>
 <br>DALL-E 2<br>
 <br>In April 2022, OpenAI announced DALL-E 2, an updated variation of the design with more reasonable results. [219] In December 2022, OpenAI published on GitHub software application for Point-E, a new fundamental system for converting a text description into a 3-dimensional model. [220]
 <br>DALL-E 3<br>
 <br>In September 2023, OpenAI announced DALL-E 3, a more powerful design much better able to produce images from complex descriptions without manual prompt engineering and render complicated details like hands and text. [221] It was released to the public as a [ChatGPT](https://git.jordanbray.com) Plus function in October. [222]
 <br>Text-to-video<br>
 <br>Sora<br>
 <br>Sora is a text-to-video design that can create videos based upon short detailed triggers [223] along with extend existing videos forwards or in reverse in time. [224] It can produce videos with resolution up to 1920x1080 or 1080x1920. The optimum length of generated videos is unidentified.<br>
 <br>Sora's advancement group called it after the Japanese word for "sky", to signify its "unlimited innovative capacity". [223] Sora's technology is an adjustment of the innovation behind the DALL · E 3 [text-to-image](https://job.honline.ma) model. [225] OpenAI trained the system utilizing publicly-available videos in addition to copyrighted videos certified for that function, however did not expose the number or the exact sources of the videos. [223]
 <br>OpenAI showed some [Sora-created high-definition](https://careers.webdschool.com) videos to the public on February 15, 2024, specifying that it could generate videos approximately one minute long. It also shared a technical report highlighting the techniques used to train the model, and the model's abilities. [225] It acknowledged some of its imperfections, including battles simulating complicated physics. [226] Will Douglas Heaven of the MIT Technology Review called the presentation videos "impressive", however noted that they should have been cherry-picked and might not represent Sora's common output. [225]
 <br>Despite uncertainty from some scholastic leaders following Sora's public demo, notable entertainment-industry figures have shown substantial interest in the technology's potential. In an interview, actor/filmmaker Tyler Perry [revealed](https://municipalitybank.com) his awe at the technology's ability to generate sensible video from text descriptions, citing its possible to change storytelling and content production. He said that his enjoyment about Sora's possibilities was so strong that he had actually chosen to stop briefly strategies for expanding his Atlanta-based movie studio. [227]
 <br>Speech-to-text<br>
 <br>Whisper<br>
 <br>Released in 2022, Whisper is a general-purpose speech acknowledgment model. [228] It is trained on a large dataset of varied audio and is also a multi-task design that can [perform multilingual](https://bikapsul.com) speech acknowledgment along with speech translation and language recognition. [229]
 <br>Music generation<br>
 <br>MuseNet<br>
 <br>Released in 2019, MuseNet is a deep neural net trained to predict subsequent musical notes in MIDI music files. It can produce songs with 10 instruments in 15 designs. According to The Verge, a song produced by MuseNet tends to start fairly but then fall into mayhem the longer it plays. [230] [231] In pop culture, initial applications of this tool were used as early as 2020 for the web mental thriller Ben Drowned to create music for the titular character. [232] [233]
 <br>Jukebox<br>
 <br>Released in 2020, Jukebox is an open-sourced algorithm to create music with vocals. After training on 1.2 million samples, the system accepts a category, artist, and a bit of lyrics and outputs tune samples. OpenAI mentioned the tunes "reveal local musical coherence [and] follow conventional chord patterns" however acknowledged that the songs lack "familiar larger musical structures such as choruses that duplicate" and that "there is a significant space" between Jukebox and [human-generated music](https://git.agri-sys.com). The Verge stated "It's technologically outstanding, even if the results sound like mushy variations of songs that may feel familiar", while Business Insider mentioned "remarkably, a few of the resulting tunes are catchy and sound legitimate". [234] [235] [236]
 <br>Interface<br>
 <br>Debate Game<br>
 <br>In 2018, OpenAI released the Debate Game, which [teaches makers](http://tfjiang.cn32773) to debate toy problems in front of a human judge. The purpose is to research study whether such a method may assist in auditing [AI](http://xn--jj-xu1im7bd43bzvos7a5l04n158a8xe.com) choices and in establishing explainable [AI](https://tradingram.in). [237] [238]
