- Temperature auto-clamping for MiniMax models: (0, 1] range enforcement - <think> tag handling for MiniMax M2.7 reasoning output (alongside existing <thinking> support) - MiniMax configuration example in mykey_template.py - Updated README.md and GETTING_STARTED.md with MiniMax provider docs - 19 unit tests + 6 integration tests (3 live tests with MINIMAX_API_KEY) MiniMax models (M2.7, M2.7-highspeed, M2.5, M2.5-highspeed) are accessed via the standard OpenAI-compatible interface at https://api.minimax.io/v1, using the existing LLMSession with an 'oai'-prefixed config key.
