- **OpenAI's Python SDK adds GPT-6.1 Sol** (Assistant changes, [OpenAI](https://cookiesforai.app/ai-news/openai), 29 SEP 2026): Version 3.21.0 of the official OpenAI Python SDK adds the GPT-6.1 Sol model identifier. Why it matters: Apps built on OpenAI's API can test GPT-6.1 Sol through the official SDK. [OpenAI Python SDK releases](https://github.com/openai/openai-python/releases/tag/v3.21.0)
- **Codex makes GPT-6.1 Sol its default model** (Assistant changes, [OpenAI](https://cookiesforai.app/ai-news/openai), 29 SEP 2026): Codex 0.159.1 adds GPT-6.1 Sol as the default model in the bundled catalog and the Amazon Bedrock Mantle and Runtime catalogs.

New input can steer Codex during model responses or long-running code-mode calls. Why it matters: Redirecting a coding agent mid-task saves time on long runs.
