A pelican for GPT-5.5 via the semi-official Codex backdoor API

Simon Willison 行业观点 入门 Impact: 7/10

Although OpenAI's latest model GPT-5.5 hasn't officially launched its API, developers are already accessing it through a 'semi-official backdoor' in its Codex CLI using their ChatGPT subscription, revealing new dynamics in the battle over AI model distribution channels.

Key Points

  • GPT-5.5 is released but its API is not yet publicly available
  • limited to ChatGPT subscribers and Codex
  • The developer community discovered they can call the model directly using existing subscriptions via a specific Codex CLI endpoint
  • OpenAI tacitly approves or even encourages this
  • in stark contrast to Anthropic's ban of similar tools
  • Simon Willison developed an LLM plugin based on this
  • allowing any developer to 'freeload' the API via subscription
