Key takeaways · AI-distilled
Cline replaced XML-formatted tool calls inside model text with tool definitions sent as JSON schemas to providers' native tool-calling APIs. Cline reports fewer 'invalid API response' errors, with the clearest gain on gpt-5-codex.
Models without native tool-calling support keep Cline's text-based tool format, and native calling excludes gpt-5-chat even though other GPT-5 models are supported.
Cline made auto-approve always on by default and removed the main toggle, favorites, 'Toggle all' and the max-requests limit, saying those features added complexity without meaningful value.
MiniMax M2 uses what MiniMax calls interleaved thinking, re-evaluating its approach throughout a request as tool outputs arrive instead of reasoning only at the start. It was free in the Cline provider until November 7, 2025.
