| Family | Transport | Default protocol | Fallback chain | Tool delivery | Notes |
|---|---|---|---|---|---|
| Qwen | OpenAI-compatible | json_decision_v1 | xml_decision_v1 -> react_text_v1 | api_parameter | Native tool calls are preferred when the endpoint returns tool_calls |
| Kimi | OpenAI-compatible | json_decision_v1 | react_text_v1 | api_parameter | Keep the same coding-agent shape with minimal prompt churn |
| MiniMax | OpenAI-compatible | minimax_tool_call_v1 | terminus_xml_v1 -> terminus_json_v1 -> json_decision_v1 | api_parameter | Preserves the MiniMax-specific parser advantage |
gpt-oss | OpenAI-compatible | json_decision_v1 | react_text_v1 | api_parameter | Targets open-weight or third-party compatible serving |
| Gemma 4 | OpenAI-compatible | json_decision_v1 | react_text_v1 | prompt_injection | Served Gemma 4 path, not native Gemini SDK binding |
Use the matrix correctly
This table is not a ranking. It is the default harness contract QitOS will use when you ask for a family preset. If you need to override one part, do it explicitly:- override the protocol
- override the base URL
- override the model name
