OpenAI Update

OpenAI has released a dev-digest.

In case you’re not aware, the Response API is their replacement for the “standard” Chat Completion API, which is practically no longer being developed. https://openai.com/index/new-tools-and-features-in-the-responses-api/

  • [[OpenAI Response API]] Added support for remote MCP. This wasn’t hard to implement on one’s own side. And I might continue doing so to maintain control and be able to influence decision-making. But for very simple projects, this is an interesting possibility.
  • [Response API] Added gpt-image-1 as a tool with image streaming and editing.
  • [Response API] Code Interpreter Tool: writing and running Python code. Sounds cool, and in certain cases, it improves answer quality, but 3 cents for each container creation for my personal tasks isn’t worth it. Although for a data-scientist assistant, it might be quite justified. Especially paired with File search, which allows uploading files and searching through them.
  • [Response API] Background mode: so you don’t have to wait synchronously, but can send and poll for status.
  • [Response API] Reasoning summaries: you still can’t see the chain-of-thought of reasoning models (I still don’t understand why), but now you can at least get a summary. I wonder if it will differ much from the thoughts the model writes directly in the response (or tool call) if asked. In theory, it’s useful for “debugging” prompts.
  • Added “flex” mode to all APIs: models respond slower, but the prices are like in the Batch API + a discount for cached input tokens. For now, it’s in beta and only available for o3 and o4-mini. https://platform.openai.com/docs/guides/flex-processing
  • Enabled fine-tuning for o4-mini.
  • In Codex CLI, you can now log in via ChatGPT. ChatGPT Plus and Pro users can redeem $5 and $50 in free API credits, respectively, for the next 2 weeks.
  • In Codex CLI, a new model codex-mini was added, for which you can get 10M free tokens if you sell your soul provide access to your data.
  • Codex is now available in ChatGPT Pro and Team.
