<br>Announced in 2016, Gym is an open-source Python library designed to help with the advancement of support learning algorithms. It aimed to standardize how environments are specified in [AI](https://www.mgtow.tv) research, making released research study more easily reproducible [24] [144] while offering users with an easy user interface for connecting with these environments. In 2022, new advancements of Gym have been moved to the library Gymnasium. [145] [146]
<br>Gym Retro<br>
<br>Released in 2018, Gym Retro is a platform for support learning (RL) research on video games [147] using RL algorithms and research [study generalization](http://165.22.249.528888). [Prior RL](http://www.boot-gebraucht.de) research focused mainly on optimizing agents to fix single tasks. Gym Retro gives the capability to generalize in between games with comparable principles however various appearances.<br>
<br>RoboSumo<br>
<br>Released in 2017, RoboSumo is a virtual world where humanoid metalearning robot agents initially do not have knowledge of how to even walk, but are given the goals of finding out to move and to press the opposing representative out of the ring. [148] Through this adversarial knowing process, [yewiki.org](https://www.yewiki.org/User:HamishKidman) the representatives discover how to adjust to altering conditions. When a representative is then gotten rid of from this virtual environment and positioned in a new virtual environment with high winds, the representative braces to remain upright, suggesting it had actually discovered how to stabilize in a generalized way. [148] [149] OpenAI's Igor Mordatch argued that competition in between representatives could produce an intelligence "arms race" that might increase a representative's ability to operate even outside the context of the competitors. [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](https://youtoosocialnetwork.com) 2, that learn to play against human gamers at a high ability level entirely through trial-and-error algorithms. Before ending up being a group of 5, the first public demonstration took place at The International 2017, the yearly premiere champion competition for the game, where Dendi, a professional Ukrainian player, 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 genuine time, which the knowing software was an action in the direction of creating software application that can deal with complicated jobs like a cosmetic surgeon. [152] [153] The system utilizes a kind of reinforcement learning, as the bots learn gradually by playing against themselves hundreds of times a day for months, and are rewarded for actions such as eliminating an enemy and taking [map goals](https://www.netrecruit.al). [154] [155] [156]
<br>By June 2018, the ability of the bots broadened to play together as a full team of 5, and they were able to beat groups of amateur and semi-professional players. [157] [154] [158] [159] At The International 2018, OpenAI Five played in 2 exhibition matches against expert players, but ended up losing both games. [160] [161] [162] In April 2019, OpenAI Five beat OG, the reigning world champions of the video game at the time, 2:0 in a live exhibition 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](https://scholarpool.com) open online competitors, winning 99.4% of those games. [165]
<br>OpenAI 5's mechanisms in Dota 2's bot gamer shows the obstacles of [AI](https://umindconsulting.com) systems in multiplayer online fight arena (MOBA) games and how OpenAI Five has shown making use of deep reinforcement learning (DRL) representatives to attain superhuman proficiency in Dota 2 matches. [166]
<br>Dactyl<br>
<br>Developed in 2018, Dactyl utilizes maker finding out to train a Shadow Hand, a human-like robot hand, to control physical things. [167] It finds out totally in simulation utilizing the exact same RL algorithms and training code as OpenAI Five. OpenAI tackled the things orientation issue by utilizing domain randomization, a simulation technique which exposes the student to a range of experiences rather than [attempting](http://git.moneo.lv) to fit to reality. The set-up for Dactyl, aside from having movement tracking cameras, also has RGB cams to enable the robotic to control an approximate object by seeing it. In 2018, OpenAI revealed that the system had the ability to manipulate a cube and an [octagonal prism](https://repo.gusdya.net). [168]
<br>In 2019, OpenAI showed that Dactyl might [resolve](https://git.xxb.lttc.cn) a Rubik's Cube. The [robotic](https://setiathome.berkeley.edu) had the ability to resolve the puzzle 60% of the time. Objects like the Rubik's Cube introduce intricate physics that is harder to model. OpenAI did this by improving the toughness of Dactyl to perturbations by utilizing Automatic Domain Randomization (ADR), a simulation method of producing gradually more difficult environments. ADR differs from manual domain randomization by not requiring a human to specify randomization ranges. [169]
<br>API<br>
<br>In June 2020, OpenAI revealed a multi-purpose API which it said was "for accessing new [AI](https://friendfairs.com) designs developed by OpenAI" to let developers get in touch with it for "any English language [AI](https://git.jamarketingllc.com) job". [170] [171]
<br>Text generation<br>
<br>The business has actually popularized generative pretrained transformers (GPT). [172]
<br>OpenAI's initial GPT design ("GPT-1")<br>
<br>The original paper on generative pre-training of a design was written by Alec Radford and his colleagues, and published in preprint on OpenAI's site on June 11, 2018. [173] It revealed how a generative model of language might obtain world knowledge and [procedure long-range](https://www.diekassa.at) reliances by pre-training on a varied corpus with long stretches of contiguous text.<br>
<br>GPT-2<br>
<br>Generative Pre-trained Transformer 2 ("GPT-2") is a without supervision transformer language model and the follower to OpenAI's initial GPT model ("GPT-1"). GPT-2 was announced in February 2019, with only restricted demonstrative [versions](https://www.keeloke.com) at first released to the public. The complete version of GPT-2 was not instantly launched due to issue about prospective abuse, consisting of applications for writing fake news. [174] Some specialists revealed uncertainty that GPT-2 posed a considerable risk.<br>
<br>In reaction to GPT-2, the Allen Institute for Artificial Intelligence reacted with a tool to identify "neural phony news". [175] Other researchers, such as Jeremy Howard, alerted of "the technology to absolutely fill Twitter, email, and the web up with reasonable-sounding, context-appropriate prose, which would muffle all other speech and be difficult to filter". [176] In November 2019, OpenAI launched the total variation of the GPT-2 language model. [177] Several sites host interactive demonstrations of different instances of GPT-2 and other transformer designs. [178] [179] [180]
<br>GPT-2's authors argue unsupervised language designs to be general-purpose learners, highlighted by GPT-2 attaining advanced accuracy and perplexity on 7 of 8 zero-shot tasks (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 slightly 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 utilizing byte pair encoding. This permits 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 model and the [successor](https://iesoundtrack.tv) to GPT-2. [182] [183] [184] OpenAI specified that the complete version of GPT-3 contained 175 billion criteria, [184] 2 orders of magnitude bigger than the 1.5 billion [185] in the complete variation of GPT-2 (although GPT-3 models with as few as 125 million parameters were also trained). [186]
<br>OpenAI mentioned that GPT-3 succeeded at certain "meta-learning" tasks and might generalize the function of a single input-output pair. The GPT-3 release paper provided examples of translation and cross-linguistic transfer knowing between English and Romanian, and in between English and German. [184]
<br>GPT-3 drastically improved benchmark results over GPT-2. OpenAI warned that such scaling-up of [language models](http://gitlab.iyunfish.com) might be approaching or experiencing the fundamental capability constraints of predictive language models. [187] Pre-training GPT-3 needed a number of thousand petaflop/s-days [b] of compute, [compared](https://profesional.id) to tens of petaflop/s-days for the full GPT-2 model. [184] Like its predecessor, [174] the GPT-3 trained model was not immediately released to the general public for issues of possible abuse, although OpenAI planned to enable gain access to through a [paid cloud](https://iamzoyah.com) API after a two-month free private beta that began in June 2020. [170] [189]
<br>On September 23, 2020, GPT-3 was licensed specifically 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://koubry.com) powering the code autocompletion tool GitHub Copilot. [193] In August 2021, an API was released in private beta. [194] According to OpenAI, the model can produce working code in over a dozen shows languages, many [effectively](https://youslade.com) in Python. [192]
<br>Several issues with glitches, design defects and security vulnerabilities were cited. [195] [196]
<br>GitHub Copilot has been accused of giving off copyrighted code, with no author attribution or license. [197]
<br>OpenAI announced that they would terminate assistance for Codex API on March 23, 2023. [198]
<br>GPT-4<br>
<br>On March 14, 2023, OpenAI revealed the release of Generative Pre-trained Transformer 4 (GPT-4), efficient in accepting text or image inputs. [199] They revealed that the upgraded technology passed a simulated law school bar test 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 might likewise read, analyze or create up to 25,000 words of text, and write code in all significant shows 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 capable of taking images as input on ChatGPT. [202] OpenAI has actually decreased to expose numerous technical details and data about GPT-4, such as the [accurate size](http://121.40.194.1233000) of the model. [203]
<br>GPT-4o<br>
<br>On May 13, 2024, OpenAI announced and launched GPT-4o, which can process and generate text, images and audio. [204] GPT-4o attained modern results in voice, multilingual, and vision criteria, setting new records in audio speech recognition and [translation](http://123.207.52.1033000). [205] [206] It scored 88.7% on the Massive Multitask Language Understanding (MMLU) criteria compared to 86.5% by GPT-4. [207]
<br>On July 18, 2024, OpenAI launched GPT-4o mini, a smaller variation of GPT-4o replacing GPT-3.5 Turbo on the ChatGPT user [interface](http://124.221.76.2813000). 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 particularly helpful for enterprises, startups and designers seeking to automate services with [AI](https://freelyhelp.com) representatives. [208]
<br>o1<br>
<br>On September 12, 2024, OpenAI launched the o1-preview and o1-mini designs, which have been designed to take more time to think of their responses, causing greater precision. These models are particularly reliable in science, coding, and reasoning tasks, and were made available to ChatGPT Plus and Team members. [209] [210] In December 2024, o1-preview was replaced by o1. [211]
<br>o3<br>
<br>On December 20, 2024, OpenAI unveiled o3, the follower of the o1 [thinking model](https://justhired.co.in). OpenAI also unveiled o3-mini, a lighter and [faster variation](https://repo.maum.in) of OpenAI o3. As of December 21, 2024, this design is not available for public usage. According to OpenAI, they are testing o3 and o3-mini. [212] [213] Until January 10, 2025, security and security researchers had the chance to obtain early access to these models. [214] The design is called o3 rather than o2 to avoid confusion with [telecommunications companies](https://labs.hellowelcome.org) O2. [215]
<br>Deep research study<br>
<br>Deep research is an [agent developed](https://git.mtapi.io) by OpenAI, [systemcheck-wiki.de](https://systemcheck-wiki.de/index.php?title=Benutzer:CeciliaBradfield) revealed on February 2, 2025. It leverages the abilities of OpenAI's o3 design to perform substantial web browsing, data analysis, and synthesis, delivering detailed reports within a timeframe of 5 to thirty minutes. [216] With searching and Python tools allowed, it reached a [precision](https://www.bjs-personal.hu) 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 resemblance](http://artpia.net) between text and images. It can especially be used for image classification. [217]
<br>Text-to-image<br>
<br>DALL-E<br>
<br>Revealed in 2021, DALL-E is a [Transformer design](http://taesungco.net) that creates images from textual descriptions. [218] DALL-E uses a 12-billion-parameter version of GPT-3 to interpret natural language inputs (such as "a green leather handbag shaped like a pentagon" or "an isometric view of a sad capybara") and produce matching images. It can create pictures of sensible things ("a stained-glass window with a picture of a blue strawberry") as well as items that do not exist in reality ("a cube with the texture of a porcupine"). As of March 2021, no API or [wiki.asexuality.org](https://wiki.asexuality.org/w/index.php?title=User_talk:EttaHorvath267) code is available.<br>
<br>DALL-E 2<br>
<br>In April 2022, OpenAI announced DALL-E 2, an upgraded version of the model with more practical outcomes. [219] In December 2022, OpenAI released on GitHub software application for Point-E, a brand-new fundamental system for transforming 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 general public as a ChatGPT Plus feature 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 prompts [223] as well as extend existing videos forwards or backwards in time. [224] It can produce videos with resolution as much as 1920x1080 or 1080x1920. The optimum length of created videos is unidentified.<br>
<br>Sora's advancement team named it after the Japanese word for "sky", to symbolize its "unlimited creative potential". [223] Sora's technology is an [adaptation](https://gogs.koljastrohm-games.com) of the innovation behind the DALL · E 3 text-to-image model. [225] OpenAI trained the system utilizing publicly-available videos along with copyrighted videos [certified](https://njspmaca.in) for that purpose, but did not reveal the number or the exact sources of the videos. [223]
<br>OpenAI showed some Sora-created high-definition videos to the general public on February 15, 2024, mentioning that it could produce videos approximately one minute long. It also shared a technical report [highlighting](http://47.95.167.2493000) the methods used to train the model, and the model's abilities. [225] It acknowledged some of its shortcomings, including struggles imitating intricate physics. [226] Will Douglas Heaven of the MIT Technology Review called the presentation videos "outstanding", however kept in mind that they should have been cherry-picked and might not represent Sora's normal output. [225]
<br>Despite uncertainty from some academic leaders following Sora's public demo, noteworthy entertainment-industry figures have shown significant interest in the innovation's potential. In an interview, actor/filmmaker Tyler Perry expressed his astonishment at the technology's ability to generate practical video from text descriptions, mentioning its possible to transform storytelling and material production. He said that his enjoyment about Sora's possibilities was so strong that he had actually decided to stop briefly strategies for broadening his Atlanta-based motion picture studio. [227]
<br>Speech-to-text<br>
<br>Whisper<br>
<br>Released in 2022, Whisper is a general-purpose speech recognition model. [228] It is trained on a big dataset of varied audio and is likewise a multi-task model that can perform multilingual speech acknowledgment along with speech translation and language identification. [229]
<br>Music generation<br>
<br>MuseNet<br>
<br>Released in 2019, MuseNet is a deep neural net trained to anticipate subsequent musical notes in MIDI music files. It can generate tunes with 10 instruments in 15 designs. According to The Verge, a tune produced by MuseNet tends to begin fairly however then fall under chaos the longer it plays. [230] [231] In popular culture, initial applications of this tool were utilized as early as 2020 for the internet psychological 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 generate music with vocals. After training on 1.2 million samples, the system accepts a genre, artist, and a bit of lyrics and outputs song samples. OpenAI stated the songs "reveal local musical coherence [and] follow conventional chord patterns" but acknowledged that the tunes lack "familiar larger musical structures such as choruses that repeat" which "there is a substantial gap" in between Jukebox and human-generated music. The Verge stated "It's technically excellent, even if the results seem like mushy versions of songs that may feel familiar", while Business Insider mentioned "remarkably, a few of the resulting tunes are memorable and sound genuine". [234] [235] [236]
<br>User user interfaces<br>
<br>Debate Game<br>
<br>In 2018, OpenAI introduced the Debate Game, which teaches devices to debate toy issues in front of a human judge. The purpose is to research study whether such an approach may assist in auditing [AI](http://git.medtap.cn) decisions and in developing explainable [AI](http://git.r.tender.pro). [237] [238]
