<br>Announced in 2016, Gym is an open-source Python library developed to assist in the development of support learning algorithms. It aimed to standardize how environments are defined in [AI](http://118.89.58.19:3000) research, making published research study more quickly reproducible [24] [144] while offering users with an easy interface for [surgiteams.com](https://surgiteams.com/index.php/User:RolandoHorniman) engaging with these environments. In 2022, brand-new developments of Gym have actually been moved to the [library Gymnasium](http://152.136.187.229). [145] [146]
<br>Gym Retro<br>
<br>Released in 2018, Gym Retro is a platform for reinforcement knowing (RL) research study on computer game [147] utilizing RL algorithms and research [study generalization](http://47.108.94.35). Prior RL research focused mainly on optimizing representatives to resolve single tasks. Gym Retro offers the ability to generalize in between video games with similar principles however different appearances.<br>
<br>RoboSumo<br>
<br>Released in 2017, RoboSumo is a virtual world where humanoid metalearning robot representatives at first lack knowledge of how to even stroll, [surgiteams.com](https://surgiteams.com/index.php/User:CathleenMadison) but are offered the goals of [finding](https://kiaoragastronomiasocial.com) out to move and to press the opposing agent out of the ring. [148] Through this adversarial learning process, the representatives learn how to adapt to changing conditions. When an agent is then gotten rid of from this virtual environment and put in a new virtual environment with high winds, the agent braces to remain upright, recommending it had actually found out how to balance in a generalized method. [148] [149] OpenAI's Igor Mordatch argued that competition in between agents could produce an intelligence "arms race" that might increase a representative's ability to function even outside the context of the competitors. [148]
<br>OpenAI 5<br>
<br>OpenAI Five is a team of 5 OpenAI-curated bots used in the competitive five-on-five computer game Dota 2, that discover to play against human gamers at a high skill level entirely through experimental algorithms. Before becoming a team of 5, the first public demonstration occurred at The International 2017, the yearly premiere champion tournament for the video 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 discovered by playing against itself for two weeks of actual time, which the [knowing software](https://socialpix.club) was a step in the direction of creating software [application](https://www.miptrucking.net) that can deal with complicated tasks like a cosmetic surgeon. [152] [153] The system uses a type of reinforcement learning, as the bots find out gradually by playing against themselves numerous times a day for [raovatonline.org](https://raovatonline.org/author/alvaellwood/) months, and are rewarded for actions such as killing an opponent and taking map objectives. [154] [155] [156]
<br>By June 2018, the [ability](https://gitea.rodaw.net) 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 players](https://jollyday.club). [157] [154] [158] [159] At The International 2018, OpenAI Five played in 2 exhibition matches against professional gamers, but ended up losing both video games. [160] [161] [162] In April 2019, OpenAI Five beat OG, the reigning world champs of the video game at the time, 2:0 in a live exhibition match in San Francisco. [163] [164] The bots' final public appearance came later on that month, where they played in 42,729 total games in a four-day open online competition, winning 99.4% of those games. [165]
<br>OpenAI 5's mechanisms in Dota 2's bot player shows the challenges of [AI](http://13.228.87.95) systems in multiplayer online battle arena (MOBA) [video games](http://101.132.163.1963000) and how OpenAI Five has actually demonstrated using deep support knowing (DRL) agents to attain superhuman proficiency in Dota 2 matches. [166]
<br>Dactyl<br>
<br>Developed in 2018, Dactyl uses maker learning to train a Shadow Hand, a human-like robot hand, to control physical things. [167] It learns totally in simulation using the exact same RL algorithms and training code as OpenAI Five. OpenAI dealt with the things orientation issue by utilizing domain randomization, a simulation approach which exposes the learner to a variety of experiences instead of trying to fit to reality. The set-up for Dactyl, aside from having motion tracking cameras, also has RGB video cameras to enable the robotic to manipulate an arbitrary item by seeing it. In 2018, OpenAI revealed that the system was able to control a cube and an octagonal prism. [168]
<br>In 2019, OpenAI demonstrated that Dactyl could fix a Rubik's Cube. The robotic was able to solve the puzzle 60% of the time. Objects like the Rubik's Cube introduce complicated physics that is harder to model. OpenAI did this by enhancing the toughness of Dactyl to perturbations by utilizing Automatic Domain Randomization (ADR), a simulation approach of producing gradually more challenging environments. ADR differs from manual domain randomization by not needing a human to specify randomization ranges. [169]
<br>API<br>
<br>In June 2020, [OpenAI revealed](http://carecall.co.kr) a multi-purpose API which it said was "for accessing brand-new [AI](https://www.lizyum.com) designs established by OpenAI" to let developers call on it for "any English language [AI](https://172.105.135.218) job". [170] [171]
<br>Text generation<br>
<br>The company has popularized generative pretrained transformers (GPT). [172]
<br>OpenAI's initial GPT model ("GPT-1")<br>
<br>The [original](http://8.142.36.793000) paper on generative pre-training of a transformer-based language model was written by Alec Radford and his colleagues, and released in [preprint](https://ayjmultiservices.com) on OpenAI's website on June 11, 2018. [173] It [demonstrated](http://209.141.61.263000) how a generative design of language could obtain world knowledge and process long-range 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 not being watched transformer language model and the successor [it-viking.ch](http://it-viking.ch/index.php/User:AngelicaSnowball) to OpenAI's original GPT design ("GPT-1"). GPT-2 was revealed in February 2019, with only restricted demonstrative versions at first launched to the public. The full version of GPT-2 was not instantly released due to concern about possible misuse, consisting of applications for composing fake news. [174] Some specialists expressed uncertainty that GPT-2 positioned a significant danger.<br>
<br>In reaction to GPT-2, the Allen Institute for Artificial Intelligence responded with a tool to discover "neural fake news". [175] Other researchers, such as Jeremy Howard, cautioned of "the technology to totally fill Twitter, email, and the web up with reasonable-sounding, context-appropriate prose, which would drown out all other speech and be difficult to filter". [176] In November 2019, OpenAI released the complete variation of the GPT-2 language design. [177] Several websites host interactive presentations of various instances of GPT-2 and other transformer models. [178] [179] [180]
<br>GPT-2's authors argue without supervision language designs to be general-purpose learners, shown by GPT-2 attaining state-of-the-art precision and perplexity on 7 of 8 zero-shot tasks (i.e. the model was not further trained on any task-specific input-output examples).<br>
<br>The corpus it was trained on, called WebText, contains a little 40 gigabytes of text from URLs shared in Reddit submissions with a minimum of 3 upvotes. It avoids certain concerns encoding vocabulary with word tokens by utilizing byte pair encoding. This permits representing any string of characters by encoding both private characters and multiple-character tokens. [181]
<br>GPT-3<br>
<br>First explained in May 2020, [engel-und-waisen.de](http://www.engel-und-waisen.de/index.php/Benutzer:RoxanneRawson) Generative Pre-trained [a] Transformer 3 (GPT-3) is a not being watched transformer language design and the successor to GPT-2. [182] [183] [184] OpenAI mentioned that the full version of GPT-3 contained 175 billion specifications, [184] two orders of magnitude larger than the 1.5 billion [185] in the full version of GPT-2 (although GPT-3 designs with as couple of as 125 million parameters were also trained). [186]
<br>OpenAI mentioned that GPT-3 was successful at certain "meta-learning" tasks and could generalize the [function](https://prosafely.com) of a single input-output pair. The GPT-3 release paper provided examples of translation and [cross-linguistic transfer](https://noaisocial.pro) knowing in between English and Romanian, and in between English and German. [184]
<br>GPT-3 dramatically improved [benchmark outcomes](https://app.hireon.cc) over GPT-2. OpenAI cautioned that such scaling-up of language designs might be approaching or experiencing the fundamental ability constraints of predictive language models. [187] Pre-training GPT-3 required numerous thousand petaflop/s-days [b] of calculate, [compared](http://motojic.com) to 10s of petaflop/s-days for the full GPT-2 model. [184] Like its predecessor, [174] the GPT-3 trained model was not immediately launched to the general public for concerns of possible abuse, although OpenAI planned to allow gain access to through a [paid cloud](https://redmonde.es) API after a two-month totally free personal beta that started in June 2020. [170] [189]
<br>On September 23, 2020, GPT-3 was certified specifically to Microsoft. [190] [191]
<br>Codex<br>
<br>Announced in mid-2021, Codex is a descendant of GPT-3 that has actually additionally been trained on code from 54 million GitHub repositories, [192] [193] and is the [AI](https://www.ahhand.com) powering the code autocompletion tool GitHub Copilot. [193] In August 2021, an API was released in personal beta. [194] According to OpenAI, the model can produce working code in over a dozen shows languages, [disgaeawiki.info](https://disgaeawiki.info/index.php/User:SusieGoodwin) most effectively in Python. [192]
<br>Several concerns with glitches, style flaws and were cited. [195] [196]
<br>GitHub Copilot has actually been implicated of producing copyrighted code, without any author attribution or license. [197]
<br>OpenAI announced that they would stop assistance for 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), efficient in accepting text or image inputs. [199] They announced that the upgraded innovation passed a simulated law school bar exam with a rating around the top 10% of test takers. (By contrast, GPT-3.5 scored around the bottom 10%.) They said that GPT-4 could likewise check out, analyze or produce as much as 25,000 words of text, and compose code in all significant programming languages. [200]
<br>Observers reported that the model of ChatGPT using GPT-4 was an enhancement on the previous GPT-3.5-based model, with the caveat that GPT-4 [retained](https://www.athleticzoneforum.com) a few of the issues with earlier revisions. [201] GPT-4 is likewise [efficient](https://gitea.belanjaparts.com) in taking images as input on ChatGPT. [202] OpenAI has decreased to reveal numerous technical [details](https://camtalking.com) and [yewiki.org](https://www.yewiki.org/User:WinifredHassell) stats about GPT-4, such as the exact size of the design. [203]
<br>GPT-4o<br>
<br>On May 13, 2024, OpenAI revealed and launched GPT-4o, which can process and create text, images and audio. [204] GPT-4o attained state-of-the-art lead to voice, multilingual, and vision benchmarks, setting new records in [audio speech](http://117.50.220.1918418) acknowledgment and translation. [205] [206] It scored 88.7% on the Massive Multitask Language Understanding (MMLU) standard 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 user 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 expects it to be especially beneficial for business, startups and developers looking for to automate services with [AI](http://8.137.54.213:9000) agents. [208]

[211]
<br>o3<br>
<br>On December 20, 2024, OpenAI unveiled o3, the successor of the o1 [reasoning design](https://video.disneyemployees.net). OpenAI also revealed o3-mini, a lighter and much faster variation of OpenAI o3. As of December 21, 2024, this design is not available for public use. According to OpenAI, they are testing o3 and o3-mini. [212] [213] Until January 10, 2025, safety and security scientists had the opportunity to obtain early access to these models. [214] The design is called o3 instead of o2 to avoid confusion with telecoms companies O2. [215]
<br>Deep research<br>
<br>Deep research study is an [agent developed](http://xingyunyi.cn3000) by OpenAI, unveiled on February 2, 2025. It leverages the capabilities of OpenAI's o3 design to carry out extensive web surfing, data analysis, and synthesis, providing detailed reports within a timeframe of 5 to thirty minutes. [216] With browsing and Python tools allowed, it reached an accuracy of 26.6 percent on HLE (Humanity's Last Exam) standard. [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 in 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 model that develops images from textual descriptions. [218] DALL-E utilizes a 12-billion-parameter version of GPT-3 to translate natural language inputs (such as "a green leather purse shaped like a pentagon" or "an isometric view of a sad capybara") and produce matching images. It can produce pictures of realistic items ("a stained-glass window with an image of a blue strawberry") as well as things that do not exist in [reality](http://yijichain.com) ("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 version of the design with more sensible results. [219] In December 2022, OpenAI published on GitHub [software](http://moyora.today) for Point-E, a new basic system for converting a [text description](https://bertlierecruitment.co.za) into a 3-dimensional model. [220]
<br>DALL-E 3<br>
<br>In September 2023, OpenAI announced DALL-E 3, a more effective design much better able to generate images from complicated 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 produce videos based upon short detailed prompts [223] along with extend existing videos forwards or backwards in time. [224] It can produce videos with resolution approximately 1920x1080 or 1080x1920. The optimum length of generated videos is unknown.<br>
<br>Sora's advancement group called it after the [Japanese](https://yeetube.com) word for "sky", to represent its "unlimited creative potential". [223] Sora's technology is an adjustment of the innovation behind the DALL · E 3 text-to-image model. [225] OpenAI trained the system using publicly-available videos in addition to copyrighted videos licensed for that purpose, however did not expose the number or the specific sources of the videos. [223]
<br>OpenAI demonstrated some Sora-created high-definition videos to the public on February 15, 2024, specifying that it might generate videos up to one minute long. It also shared a technical report highlighting the techniques used to train the design, and the model's capabilities. [225] It acknowledged some of its shortcomings, consisting of battles imitating complicated physics. [226] Will Douglas Heaven of the MIT Technology Review called the presentation videos "impressive", however kept in mind that they need to have been cherry-picked and might not represent Sora's typical output. [225]
<br>Despite uncertainty from some academic leaders following Sora's public demonstration, significant entertainment-industry figures have actually revealed significant interest in the technology's potential. In an interview, actor/filmmaker Tyler Perry revealed his awe at the technology's capability to produce realistic video from text descriptions, mentioning its possible to change storytelling and content development. He said that his excitement about Sora's possibilities was so strong that he had actually chosen to stop briefly prepare for [expanding](https://gitea.cisetech.com) his Atlanta-based motion picture studio. [227]

[229]
<br>Music generation<br>
<br>MuseNet<br>
<br>Released in 2019, MuseNet is a deep neural net trained to forecast subsequent musical notes in MIDI music files. It can generate tunes with 10 instruments in 15 styles. According to The Verge, a song generated by MuseNet tends to begin fairly but then fall under turmoil the longer it plays. [230] [231] In popular culture, initial applications of this tool were used as early as 2020 for the web psychological [thriller](https://git.luoui.com2443) Ben Drowned to produce 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](https://agora-antikes.gr) a genre, artist, and a bit of lyrics and outputs tune samples. OpenAI mentioned the songs "reveal local musical coherence [and] follow conventional chord patterns" but acknowledged that the songs lack "familiar larger musical structures such as choruses that repeat" and that "there is a considerable gap" in between Jukebox and human-generated music. The Verge stated "It's technically excellent, even if the outcomes sound like mushy variations of tunes that may feel familiar", while Business Insider specified "remarkably, a few of the resulting songs are memorable and sound genuine". [234] [235] [236]
<br>Interface<br>
<br>Debate Game<br>
<br>In 2018, OpenAI introduced the Debate Game, which teaches machines to discuss toy problems in front of a human judge. The purpose is to research study whether such an approach may help in auditing [AI](https://www.9iii9.com) decisions and in developing explainable [AI](https://gitlab.lycoops.be). [237] [238]
<br>Microscope<br>
<br>Released in 2020, Microscope [239] is a collection of visualizations of every considerable layer and neuron of 8 neural network models which are often studied in interpretability. [240] Microscope was developed to examine the features that form inside these neural networks quickly. The designs consisted of are AlexNet, VGG-19, different versions of Inception, and different variations of CLIP Resnet. [241]
<br>ChatGPT<br>
<br>Launched in November 2022, ChatGPT is an expert system tool developed on top of GPT-3 that provides a conversational user interface that permits users to ask concerns in natural language. The system then reacts with a response within seconds.<br>
