Define tools with the OpenAI-style tools parameter. Choose models that list tool-calling support on the model detail page; complex tools, multi-tool selection, and argument reliability vary by model.

| Model | Level | Note |
|---|---|---|
| Gemini 3.x family | Selected models | Use OpenAI-style tools and structured outputs on models such as Gemini 3.6 Flash. Current web grounding requires the explicit SeaLink web_search tool; ordinary chat does not auto-browse or silently enable Google grounding charges. |
| Claude family | Selected models | Use the model detail page to confirm Anthropic tool-use support. |
| GPT family | Selected models | OpenAI-style tools; behavior depends on the selected model. |
| Qwen family | Selected models | Use OpenAI-compatible request shape where tool calling is enabled. |
| Doubao / Kimi / DeepSeek / GLM | Model-dependent | Validate tool-call quality with your own schemas before production. |
Chat requests do not browse automatically. Pass web_search explicitly when you need current sources. Kimi-compatible clients may use $web_search.
