Key Points

  • The “llm 0.31” release adds new support for the GPT-5.5 OpenAI model via the command-line flag `-m gpt-5.5`.
  • It introduces a `-o verbosity` option to control text verbosity for GPT-5+ OpenAI models with values `low`, `medium`, and `high`.
  • It adds an `-o image_detail` option to set the image attachment detail level for OpenAI image inputs, supporting `low`, `high`, `auto`, and (for GPT-5.4/5.5) `original`.
  • Models defined in `extra-openai-models.yaml` are now also registered as asynchronous, expanding concurrency support for additional OpenAI models.
