What Are ChatGPT and Its Friends? – O’Reilly
GPT-3.5 is one of a class of language models that are sometimes called “large language models” (LLMs)
- ChatGPT itself
Developed by OpenAI; based on GPT-3.5 with specialized training. An API for ChatGPT is available. - GPT-2, 3, 3.5, and 4
Large language models developed by OpenAI. GPT-2 is open source. GPT-3 and GPT-4 are not open source, but are available for free and paid access. The user interface for GPT-4 is similar to ChatGPT. - Sydney
The internal code name of the chatbot behind Microsoft’s improved search engine, Bing. Sydney is based on GPT-4,1 with additional training. - Kosmos-1
Developed by Microsoft, and trained on image content in addition to text. Microsoft plans to release this model to developers, though they haven’t yet. - LaMDA
Developed by Google; few people have access to it, though its capabilities appear to be very similar to ChatGPT. Notorious for having led one Google employee to believe that it was sentient. - PaLM
Also developed by Google. With three times as many parameters as LaMDA, it appears to be very powerful. PaLM-E, a variant, is a multimodal model that can work with images; it has been used to control robots. Google has announced an API for PaLM, but at this point, there is only a waiting list. - Chinchilla
Also developed by Google. While it is still very large, it is significantly smaller than models like GPT-3 while offering similar performance. - Bard
Google’s code name for its chat-oriented search engine, based on their LaMDA model, and only demoed once in public. A waiting list to try Bard was recently opened. - Claude
Developed by Anthropic, a Google-funded startup. Poe is a chat app based on Claude, and available through Quora; there is a waiting list for access to the Claude API. - LLaMA
Developed by Facebook/Meta, and available to researchers by application. Facebook released a previous model, OPT-175B, to the open source community. The LLaMA source code has been ported to C++, and a small version of the model itself (7B) has been leaked to the public, yielding a model that can run on laptops. - BLOOM
An open source model developed by the BigScience workshop. - Stable Diffusion
An open source model developed by Stability AI for generating images from text. A large language model “understands” the prompt and controls a diffusion model that generates the image. Although Stable Diffusion generates images rather than text, it’s what alerted the public to the ability of AI to process human language.
