 <br>Announced in 2016, Gym is an open-source Python library developed to help with the development of reinforcement learning algorithms. It aimed to standardize how environments are specified in [AI](https://lastpiece.co.kr) research, making published research study more quickly reproducible [24] [144] while providing users with a simple user interface for connecting with these environments. In 2022, [brand-new developments](https://adventuredirty.com) of Gym have been relocated 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 computer game [147] using RL algorithms and study generalization. Prior RL research focused mainly on [optimizing representatives](http://park7.wakwak.com) to resolve single jobs. Gym Retro gives the capability to generalize between video games with comparable principles but different appearances.<br>
 <br>RoboSumo<br>
 <br>Released in 2017, RoboSumo is a virtual world where humanoid metalearning robotic agents at first lack understanding of how to even walk, however are given the objectives of finding out to move and to press the opposing representative out of the ring. [148] Through this adversarial knowing process, the agents discover how to adjust to altering conditions. When an agent is then removed from this virtual environment and placed in a brand-new virtual environment with high winds, the representative braces to remain upright, suggesting it had actually learned how to stabilize in a generalized way. [148] [149] OpenAI's Igor Mordatch argued that competition between agents might produce an intelligence "arms race" that could increase a representative's ability to work even outside the context of the competition. [148]
 <br>OpenAI 5<br>
 <br>OpenAI Five is a team of 5 OpenAI-curated bots utilized in the competitive five-on-five computer game Dota 2, that learn to play against human gamers at a high ability level entirely through trial-and-error algorithms. Before becoming a team of 5, the very first public demonstration took place at The International 2017, the yearly best [championship competition](https://ivytube.com) for the video game, where Dendi, an expert Ukrainian player, lost against a bot in a live individually matchup. [150] [151] After the match, CTO Greg Brockman explained that the bot had learned by playing against itself for 2 weeks of actual time, which the learning software was a step in the direction of developing software that can handle complicated jobs like a cosmetic surgeon. [152] [153] The system uses a kind of support 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 killing an opponent and taking map goals. [154] [155] [156]
 <br>By June 2018, the ability of the bots expanded to play together as a full team of 5, and they had the ability to beat groups of amateur and semi-professional players. [157] [154] [158] [159] At The International 2018, OpenAI Five played in two exhibit matches against expert players, but ended up losing both video games. [160] [161] [162] In April 2019, OpenAI Five beat OG, the ruling world champs 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 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](https://collegetalks.site) in Dota 2's bot player reveals the difficulties of [AI](https://app.hireon.cc) systems in multiplayer online fight arena (MOBA) video games and how OpenAI Five has actually demonstrated the use of deep support learning (DRL) agents to attain superhuman competence 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](https://git.flandre.net) hand, to control physical things. [167] It learns completely in simulation using the same RL algorithms and [training code](https://kition.mhl.tuc.gr) as OpenAI Five. OpenAI tackled the item orientation issue by [utilizing domain](https://airsofttrader.co.nz) randomization, a simulation approach which exposes the learner to a range of experiences rather than attempting to fit to truth. The set-up for Dactyl, aside from having motion tracking video cameras, likewise has RGB cameras to permit the robotic to manipulate an approximate item 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 might fix a Rubik's Cube. The robot had the ability to solve the puzzle 60% of the time. Objects like the [Rubik's Cube](https://www.jgluiggi.xyz) present [intricate physics](https://www.hireprow.com) that is harder to model. OpenAI did this by improving the robustness of Dactyl to perturbations by utilizing Automatic [Domain Randomization](https://gitea.fcliu.net) (ADR), a simulation method of generating gradually harder environments. ADR differs from manual domain randomization by not requiring a human to specify randomization varieties. [169]
 <br>API<br>
 <br>In June 2020, OpenAI revealed a multi-purpose API which it said was "for accessing new [AI](http://39.101.160.11:8099) models developed by OpenAI" to let developers contact it for "any English language [AI](https://phdjobday.eu) job". [170] [171]
 <br>Text generation<br>
 <br>The business has actually promoted generative pretrained transformers (GPT). [172]
 <br>OpenAI's original GPT design ("GPT-1")<br>
 <br>The original paper on generative pre-training of a transformer-based language model was written by Alec Radford and his colleagues, and [published](https://dispatchexpertscudo.org.uk) in preprint on OpenAI's website on June 11, 2018. [173] It demonstrated how a generative design of language might obtain world knowledge and procedure long-range [dependences](https://hub.tkgamestudios.com) by pre-training on a [varied corpus](https://energypowerworld.co.uk) 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 design and the follower to OpenAI's initial GPT design ("GPT-1"). GPT-2 was announced in February 2019, with only restricted demonstrative variations at first launched to the public. The full version of GPT-2 was not immediately launched due to issue about potential abuse, including applications for composing phony news. [174] Some specialists expressed uncertainty that GPT-2 postured a considerable threat.<br>
 <br>In reaction to GPT-2, the Allen Institute for Artificial Intelligence [reacted](https://www.viewtubs.com) with a tool to find "neural phony news". [175] Other researchers, such as Jeremy Howard, alerted of "the innovation to completely 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 total variation of the GPT-2 language design. [177] Several sites host interactive demonstrations of various circumstances of GPT-2 and other transformer models. [178] [179] [180]
 <br>GPT-2's authors argue unsupervised language models to be general-purpose learners, illustrated by GPT-2 attaining modern precision 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 a little 40 gigabytes of text from URLs shared in Reddit submissions with a minimum of 3 upvotes. It [prevents](http://123.60.97.16132768) certain concerns encoding vocabulary with word tokens by utilizing byte pair encoding. This allows representing any string of characters by encoding both specific characters and [multiple-character tokens](http://hitq.segen.co.kr). [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 to GPT-2. [182] [183] [184] OpenAI mentioned that the full version of GPT-3 contained 175 billion criteria, [184] two orders of magnitude larger than the 1.5 billion [185] in the complete version of GPT-2 (although GPT-3 designs with as couple of as 125 million specifications were likewise trained). [186]
 <br>OpenAI mentioned that GPT-3 succeeded at certain "meta-learning" jobs and might generalize the function of a single input-output pair. The GPT-3 release paper gave examples of translation and cross-linguistic transfer knowing between English and Romanian, and between English and German. [184]
 <br>GPT-3 considerably improved [benchmark](http://gitea.smartscf.cn8000) results over GPT-2. OpenAI cautioned that such scaling-up of language models might be approaching or [experiencing](http://visionline.kr) the essential capability constraints of predictive language models. [187] Pre-training GPT-3 required numerous thousand petaflop/s-days [b] of calculate, compared to 10s of petaflop/s-days for the complete GPT-2 model. [184] Like its predecessor, [174] the GPT-3 trained model was not instantly launched to the general public for issues of possible abuse, although OpenAI prepared to permit gain access to through a paid cloud API after a two-month complimentary private beta that began in June 2020. [170] [189]
 <br>On September 23, 2020, GPT-3 was licensed exclusively to Microsoft. [190] [191]
 <br>Codex<br>
 <br>Announced in mid-2021, Codex is a descendant of GPT-3 that has furthermore been trained on code from 54 million GitHub repositories, [192] [193] and is the [AI](https://redsocial.cl) powering the code autocompletion tool GitHub Copilot. [193] In August 2021, an API was launched in personal beta. [194] According to OpenAI, the model can create working code in over a dozen shows languages, a lot of efficiently in Python. [192]
 <br>Several problems with problems, style flaws and security vulnerabilities were mentioned. [195] [196]
 <br>GitHub Copilot has been accused of emitting copyrighted code, with no author attribution or license. [197]
 <br>OpenAI announced that they would discontinue 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), capable of accepting text or  [setiathome.berkeley.edu](https://setiathome.berkeley.edu/view_profile.php?userid=11857434) image inputs. [199] They revealed that the upgraded technology passed a simulated law school bar test with a rating around the top 10% of [test takers](https://hafrikplay.com). (By contrast, GPT-3.5 scored around the bottom 10%.) They said that GPT-4 could likewise read, examine or create up to 25,000 words of text, and compose code in all major programs languages. [200]
 <br>Observers reported that the version of ChatGPT using GPT-4 was an enhancement on the previous GPT-3.5-based model, with the caveat that GPT-4 retained a few of the problems with earlier modifications. [201] GPT-4 is likewise capable of taking images as input on ChatGPT. [202] OpenAI has actually decreased to reveal numerous [technical details](https://kittelartscollege.com) and data about GPT-4, such as the precise size of the model. [203]
 <br>GPT-4o<br>
 <br>On May 13, 2024, OpenAI announced and launched GPT-4o, which can process and [generate](https://git.hichinatravel.com) text, images and audio. [204] GPT-4o attained modern lead to voice,  [wavedream.wiki](https://wavedream.wiki/index.php/User:ShereeHein) 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 launched](https://www.soundofrecovery.org) GPT-4o mini, a smaller version of GPT-4o [replacing](http://129.151.171.1223000) 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 expects it to be particularly helpful for enterprises, startups and designers seeking to automate services with [AI](http://git.scdxtc.cn) agents. [208]
 <br>o1<br>
 <br>On September 12, 2024, [OpenAI launched](https://www.wotape.com) the o1-preview and o1-mini models, which have been developed to take more time to believe about their responses, leading to greater precision. These models are particularly effective in science, coding, and thinking tasks, and were made available to ChatGPT Plus and Staff member. [209] [210] In December 2024, o1-preview was replaced by o1. [211]
 <br>o3<br>
 <br>On December 20, 2024, OpenAI revealed o3, the follower of the o1 reasoning model. OpenAI also revealed o3-mini, a lighter and much faster variation of OpenAI o3. Since December 21, 2024, this design is not available for public usage. According to OpenAI, they are evaluating o3 and o3-mini.
