OpenAI has just announced the availability of a new model variant, chatgpt-4o-latest, through their API. This model is designed specifically to enhance chat use cases, offering developers the opportunity to leverage the latest advancements in chat-optimized AI.

According to the announcement on X by OpenAI Developers (@OpenAIDevs), while chatgpt-4o-latest will continuously track the latest improvements in the ChatGPT model, OpenAI recommends using gpt-4o-2024-08-06 for most API usage. This model from last week is optimized for function calling, instruction following, and other typical API operations, making it a more stable choice for those purposes.
