Generative Pre-trained Transformer 3.5 (GPT-3.5) is a sub class of GPT-3 Models created by OpenAI in 2022. On March 15, 2022, OpenAI made available new versions of GPT-3 and Codex in its API with edit and insert capabilities under the names "text-davinci-002" and "code-davinci-002". [ 28 ]
OpenAI has released significant GPT foundation models that have been sequentially numbered, to comprise its "GPT-n" series. [10] Each of these was significantly more capable than the previous, due to increased size (number of trainable parameters) and training. The most recent of these, GPT-4o, was released in May 2024. [11]
OpenAI invited safety and security researchers to apply for early access of these models until January 10, 2025. [3] There are two different models: o3 and o3-mini. [4] On January 31, 2025, OpenAI released o3-mini to all ChatGPT users (including free-tier) and some API users. o3-mini features three reasoning effort levels: low, medium and high ...
For example, the small (i.e. 117M parameter sized) GPT-2 model has had twelve attention heads and a context window of only 1k tokens. [44] In its medium version it has 345M parameters and contains 24 layers, each with 12 attention heads. For the training with gradient descent a batch size of 512 was utilized. [28]
Generative AI systems trained on words or word tokens include GPT-3, GPT-4, GPT-4o, LaMDA, LLaMA, BLOOM, Gemini and others (see List of large language models). They are capable of natural language processing, machine translation, and natural language generation and can be used as foundation models for other tasks. [62]
The next biggest model out there, as far as we're aware, is OpenAI's GPT-3, which uses a measly 175 billion parameters. Background: Language models are capable of performing a variety of functions ...
