OpenAI has posted in their official blog that GPT-4 is now accessible to paying API users. GPT-4 API was launched back in March, but was in a closed testing stage. This API is able to utilize OpenAI's large language model (LLM) to assist in coding, summarization, composition, and analysis. OpenAI is also releasing a deprecation plan for their older models in Completions API to optimize their compute capacity. OpenAI plans to expand access to ChatGPT, the API and Codex in the coming weeks. GPT-5.4, OpenAI's most recent frontier AI model, is now available via the API and Codex, as well as in ChatGPT as GPT-5.4 Thinking.
