MCP & tool use

OpenAI says the GPT-4 API is generally available and older models in the Completions API will be deprecated. Only the title confirms these two facts; the post body is empty and does not disclose scope, timeline, or affected model names. The real issue to watch is migration cost: this is both an API and model transition.

OpenAI says ChatGPT is getting memory and new controls, with 2 changes disclosed in the title. The body is empty, so default state, opt-out scope, and user-tier availability are not disclosed. The key issue is control granularity; the title alone is not enough to judge product impact.
