 <br>Announced in 2016, Gym is an [open-source Python](https://git.li-yo.ts.net) library created to assist in the development of reinforcement learning algorithms. It aimed to standardize how environments are specified in [AI](http://www.getfundis.com) research study, making released research study more easily reproducible [24] [144] while offering users with a basic interface for interacting with these environments. In 2022, brand-new developments 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 reinforcement learning (RL) research study on computer game [147] using RL algorithms and research study generalization. Prior RL research [study focused](http://xintechs.com3000) mainly on enhancing agents to solve single jobs. Gym Retro provides the ability to generalize in between video games with similar concepts but various looks.<br>
 <br>RoboSumo<br>
 <br>Released in 2017, RoboSumo is a virtual world where humanoid metalearning robotic agents at first lack knowledge of how to even stroll, however are offered the goals of discovering to move and to push the opposing representative out of the ring. [148] Through this adversarial learning process, the representatives learn how to adapt to altering conditions. When an agent is then gotten rid of from this [virtual environment](https://saathiyo.com) and put in a brand-new virtual environment with high winds, the representative braces to remain upright, suggesting it had actually found out how to balance in a generalized method. [148] [149] OpenAI's Igor Mordatch argued that competition between [representatives](http://pyfup.com3000) could produce an intelligence "arms race" that might increase an agent's capability to work even outside the context of the competition. [148]
 <br>OpenAI 5<br>
 <br>OpenAI Five is a group of 5 OpenAI-curated bots used in the competitive five-on-five computer game Dota 2, that learn to play against human players at a high ability level totally through experimental algorithms. Before ending up being a group of 5, the first public presentation happened at The International 2017, the annual premiere championship competition for the video game, where Dendi, a professional Ukrainian gamer, lost against a bot in a live one-on-one match. [150] [151] After the match, CTO Greg Brockman explained that the bot had actually discovered by [playing](http://106.15.41.156) against itself for two weeks of actual time, and that the learning software was a step in the instructions of creating software application that can deal with complex jobs like a cosmetic surgeon. [152] [153] The system uses a type of [reinforcement](http://sbstaffing4all.com) knowing, as the bots learn over time by playing against themselves hundreds of times a day for months, and are rewarded for actions such as eliminating an opponent and taking map goals. [154] [155] [156]
 <br>By June 2018, the capability of the bots broadened to play together as a full team of 5, and they had the ability to defeat groups of amateur and semi-professional gamers. [157] [154] [158] [159] At The International 2018, OpenAI Five played in 2 exhibit matches against professional gamers, but ended up losing both games. [160] [161] [162] In April 2019, OpenAI Five defeated OG, the reigning world champions of the game at the time, 2:0 in a live exhibit match in San Francisco. [163] [164] The bots' last public appearance came later that month, where they played in 42,729 total games in a four-day open online competitors, winning 99.4% of those video games. [165]
 <br>OpenAI 5's mechanisms in Dota 2's bot gamer reveals the obstacles of [AI](http://101.200.181.61) systems in multiplayer online battle arena (MOBA) video games and how OpenAI Five has demonstrated making use of deep reinforcement [learning](https://git.rungyun.cn) (DRL) representatives to attain superhuman skills in Dota 2 matches. [166]
 <br>Dactyl<br>
 <br>Developed in 2018, Dactyl utilizes machine finding out to train a Shadow Hand, a human-like robot hand, to control physical items. [167] It finds out totally in simulation utilizing the exact same RL algorithms and training code as OpenAI Five. OpenAI took on the object orientation problem by using domain randomization, a simulation approach which exposes the learner to a range of experiences instead of [attempting](https://bertlierecruitment.co.za) to fit to reality. The set-up for Dactyl, aside from having motion tracking cameras, also has RGB cams to permit the robotic to control an approximate things by seeing it. In 2018, OpenAI revealed that the system had the ability to control a cube and an octagonal prism. [168]
 <br>In 2019, OpenAI showed that Dactyl could solve a Rubik's Cube. The robotic had the [ability](https://inspiredcollectors.com) 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 improving the robustness of Dactyl to perturbations by utilizing Automatic Domain Randomization (ADR), a simulation method of generating progressively harder environments. ADR varies from manual domain randomization by not needing a human to specify [randomization ranges](http://175.24.176.23000). [169]
 <br>API<br>
 <br>In June 2020, OpenAI revealed a multi-purpose API which it said was "for accessing new [AI](https://www.garagesale.es) models developed by OpenAI" to let developers call on it for "any English language [AI](https://deepsound.goodsoundstream.com) job". [170] [171]
 <br>Text generation<br>
 <br>The business has [promoted generative](http://publicacoesacademicas.unicatolicaquixada.edu.br) pretrained [transformers](https://git.sicom.gov.co) (GPT). [172]
 <br>OpenAI's original GPT model ("GPT-1")<br>
 <br>The original paper on generative pre-training of a transformer-based language design was written by Alec Radford and his colleagues, and released in preprint on OpenAI's website on June 11, 2018. [173] It demonstrated how a generative model of language might obtain world understanding and procedure long-range dependences by pre-training on a diverse corpus with long stretches of adjoining text.<br>
 <br>GPT-2<br>
 <br>Generative Pre-trained Transformer 2 ("GPT-2") is a not being [watched](http://valueadd.kr) transformer language model and the successor to [OpenAI's original](https://www.iwatex.com) GPT design ("GPT-1"). GPT-2 was announced in February 2019, with just restricted demonstrative variations at first launched to the general public. The complete variation of GPT-2 was not instantly released due to concern about prospective abuse, including applications for writing phony news. [174] Some professionals expressed uncertainty that GPT-2 presented a considerable danger.<br>
 <br>In action to GPT-2, the Allen  for Artificial Intelligence reacted with a tool to find "neural phony news". [175] Other scientists, 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 muffle all other speech and be difficult to filter". [176] In November 2019, OpenAI launched the total variation of the GPT-2 language design. [177] Several sites host interactive demonstrations of various instances of GPT-2 and other transformer models. [178] [179] [180]
 <br>GPT-2's authors argue unsupervised language designs to be general-purpose students, illustrated by GPT-2 attaining state-of-the-art accuracy 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](https://git.rungyun.cn) of text from URLs shared in Reddit submissions with at least 3 upvotes. It avoids certain problems encoding vocabulary with word tokens by using byte pair encoding. This permits representing any string of characters by encoding both specific 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 not being watched transformer language model and the follower to GPT-2. [182] [183] [184] OpenAI specified that the full variation of GPT-3 contained 175 billion parameters, [184] two 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](https://csmsound.exagopartners.com) were also trained). [186]
 <br>OpenAI mentioned that GPT-3 succeeded at certain "meta-learning" tasks and could generalize the purpose 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 could be approaching or experiencing the basic ability constraints of predictive language models. [187] Pre-training GPT-3 required several thousand petaflop/s-days [b] of compute, compared to 10s of petaflop/s-days for the complete GPT-2 model. [184] Like its predecessor, [174] the GPT-3 trained design was not instantly [launched](https://anychinajob.com) to the public for concerns of possible abuse, although OpenAI prepared to allow gain access to through a paid cloud API after a two-month complimentary personal 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](https://startuptube.xyz) of GPT-3 that has actually in addition been trained on code from 54 million GitHub repositories, [192] [193] and is the [AI](https://community.scriptstribe.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 create working code in over a [dozen programs](https://git.muehlberg.net) languages, most efficiently in Python. [192]
 <br>Several problems with glitches, design defects and security vulnerabilities were mentioned. [195] [196]
 <br>GitHub Copilot has been accused of releasing copyrighted code, with no author attribution or license. [197]
 <br>OpenAI announced that they would terminate support 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 updated technology passed a simulated law school bar examination 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 might likewise check out, examine or generate approximately 25,000 words of text, and compose code in all major shows languages. [200]
 <br>[Observers](https://kenyansocial.com) reported that the model of ChatGPT using GPT-4 was an improvement on the previous GPT-3.5-based version, with the caution that GPT-4 retained a few of the issues with earlier modifications. [201] GPT-4 is also efficient in taking images as input on ChatGPT. [202] OpenAI has declined to reveal numerous technical details and stats about GPT-4, such as the [precise size](http://hybrid-forum.ru) of the design. [203]
 <br>GPT-4o<br>
 <br>On May 13, 2024, OpenAI revealed and launched GPT-4o, which can process and generate text, images and audio. [204] GPT-4o attained advanced lead to voice, multilingual, and vision benchmarks, setting new records in audio speech recognition and translation. [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 version of GPT-4o changing 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, start-ups and designers looking for to automate services with [AI](http://115.124.96.179:3000) representatives. [208]
 <br>o1<br>
 <br>On September 12, 2024, OpenAI released the o1-preview and o1-mini models, which have actually been developed to take more time to think of their actions, causing greater precision.

 <br>On December 20,  [surgiteams.com](https://surgiteams.com/index.php/User:NXOFrancisco) 2024, [OpenAI revealed](https://hip-hop.id) o3, the follower of the o1 thinking model. OpenAI likewise revealed o3-mini, a lighter and quicker variation of OpenAI o3. As of December 21, 2024, this model 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 researchers](http://connect.lankung.com) had the chance to obtain early access to these designs. [214] The design is called o3 instead of o2 to prevent confusion with telecoms providers O2. [215]
 <br>Deep research<br>
 <br>Deep research is an agent established by OpenAI, revealed on February 2, 2025. It leverages the capabilities of [OpenAI's](http://www.andreagorini.it) o3 model to carry out extensive web browsing, information analysis, and synthesis, delivering detailed reports within a timeframe of 5 to 30 minutes. [216] With searching and Python tools enabled, it reached an accuracy of 26.6 percent on HLE (Humanity's Last Exam) criteria. [120]
 <br>Image classification<br>
 <br>CLIP<br>
 <br>Revealed in 2021, CLIP (Contrastive Language-Image Pre-training) is a model that is trained to examine the semantic resemblance in between text and images. It can notably be utilized for image category. [217]
 <br>Text-to-image<br>
 <br>DALL-E<br>
 <br>Revealed in 2021, DALL-E is a Transformer design that creates images from [textual descriptions](http://47.108.140.33). [218] DALL-E utilizes a 12[-billion-parameter](http://dnd.achoo.jp) version of GPT-3 to translate natural language inputs (such as "a green leather bag formed like a pentagon" or "an isometric view of an unfortunate capybara") and create matching images. It can create images of realistic things ("a stained-glass window with an image of a blue strawberry") as well as things that do not exist in reality ("a cube with the texture of a porcupine"). As of March 2021, no API or code is available.<br>
 <br>DALL-E 2<br>
 <br>In April 2022, OpenAI revealed DALL-E 2, an updated version of the design with more sensible outcomes. [219] In December 2022, OpenAI published on GitHub software for Point-E, a brand-new primary system for converting a text description into a 3-dimensional design. [220]
 <br>DALL-E 3<br>
 <br>In September 2023, OpenAI announced DALL-E 3, a more effective design much better able to produce images from complex descriptions without manual prompt engineering and render complex details like hands and text. [221] It was launched to the public as a [ChatGPT](https://seekinternship.ng) 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 on short detailed triggers [223] along with extend existing videos forwards or backwards in time. [224] It can create videos with resolution as much as 1920x1080 or 1080x1920. The optimum length of created videos is unknown.<br>
 <br>Sora's development group called it after the Japanese word for "sky", to signify its "limitless innovative capacity". [223] Sora's technology is an adjustment of the technology behind the DALL · E 3 text-to-image design. [225] OpenAI trained the system utilizing publicly-available videos in addition to copyrighted videos certified for that purpose, but did not expose the number or the precise 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 approaches [utilized](http://47.113.115.2393000) to train the model, and the design's abilities. [225] It acknowledged a few of its imperfections, including struggles [replicating intricate](http://118.195.204.2528080) physics. [226] Will Douglas Heaven of the MIT Technology Review called the presentation videos "excellent", but noted that they should have been cherry-picked and may not represent Sora's common output. [225]
 <br>Despite uncertainty from some [scholastic leaders](http://git.oksei.ru) following Sora's public demo, [notable](https://thathwamasijobs.com) entertainment-industry figures have actually shown considerable interest in the innovation's capacity. In an interview, actor/filmmaker Tyler Perry expressed his awe at the technology's ability to produce realistic video from text descriptions, citing its possible to reinvent storytelling and material creation. He said that his excitement about Sora's possibilities was so strong that he had actually chosen to pause prepare for broadening his Atlanta-based movie studio. [227]
 <br>Speech-to-text<br>
 <br>Whisper<br>
 <br>Released in 2022, Whisper is a general-purpose speech recognition design. [228] It is trained on a big dataset of diverse audio and is likewise a multi-task model that can carry out multilingual 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 anticipate subsequent [musical](https://pakkjob.com) notes in MIDI music files. It can produce songs with 10 instruments in 15 styles. According to The Verge, a tune produced by MuseNet tends to start fairly but then fall into mayhem the longer it plays. [230] [231] In popular culture, preliminary applications of this tool were used as early as 2020 for the web mental thriller Ben Drowned to develop music for the titular character. [232] [233]
 <br>Jukebox<br>
 <br>Released in 2020, [Jukebox](https://ka4nem.ru) is an open-sourced algorithm to generate 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 songs "reveal regional musical coherence [and] follow standard chord patterns" but acknowledged that the tunes do not have "familiar bigger musical structures such as choruses that duplicate" which "there is a considerable space" in between Jukebox and human-generated music. The [Verge stated](http://linyijiu.cn3000) "It's highly outstanding, even if the outcomes seem like mushy versions of tunes that may feel familiar", while Business Insider mentioned "surprisingly, some of the resulting songs are memorable and sound legitimate". [234] [235] [236]
 <br>Interface<br>
 <br>Debate Game<br>
 <br>In 2018, OpenAI released the Debate Game, which teaches devices to debate toy issues in front of a human judge. The function is to research whether such an approach may help in auditing [AI](http://gogs.oxusmedia.com) choices and in establishing explainable [AI](https://chutpatti.com). [237] [238]
 <br>Microscope<br>
 <br>Released in 2020, Microscope [239] is a collection of visualizations of every substantial layer and neuron of eight neural network models which are frequently studied in interpretability. [240] Microscope was developed to analyze the features that form inside these neural networks quickly. The models included are AlexNet, VGG-19, various versions of Inception, and various variations of CLIP Resnet. [241]
 <br>ChatGPT<br>
 <br>Launched in November 2022, ChatGPT is an expert system tool built on top of GPT-3 that offers a conversational interface that permits users to ask concerns in natural language. The system then reacts with a response within seconds.<br>
