编译时校验的 OpenRouter 模型 ID。`model_supports!` 宏会根据内置的 OpenRouter 索引校验模型 ID 及其所需功能，并展开为模型 ID 字符串。 ```rust use openrouter_toolkit::model_supports; const MODEL: &str = model_supports!( "openai/gpt-5.4", param::tools, input::image, output::text, ); ``` 动态变体同样适用： ```rust const MODEL: &str = model_supports!("moonshotai/kimi-k2-0905:exacto", param::tools); ``` * `param::*` — 请求参数（例如 `param::tools`） * `input::*` — 输入模态（例如 `input::image`） * `output::*` — 输出模态（例如 `output::text`）未知功能示例： ```rust const MODEL: &str = model_supports!("qwen/qwen3.7-max", param::toolz); // error: unknown OpenRouter capability `param::toolz`; did you mean `param::tools`? ``` 模型不支持的功能示例： ```rust const MODEL: &str = model_supports!("qwen/qwen3.7-max", input::image); // error: OpenRouter model `qwen/qwen3.7-max` does not support required capability(s): input::image ```

对不起。

Compile-time checked OpenRouter model ids.

model_supports! validates a model id and its required capabilities against a vendored OpenRouter index, then expands to the model id string.

use openrouter_toolkit::model_supports;

const MODEL: &str = model_supports!(
    "openai/gpt-5.4",
    param::tools,
    input::image,
    output::text,
);

Dynamic variants work too:

const MODEL: &str = model_supports!("moonshotai/kimi-k2-0905:exacto", param::tools);

param::* — request parameters (e.g. param::tools)
input::* — input modalities (e.g. input::image)
output::* — output modalities (e.g. output::text)

Unknown capability:

const MODEL: &str = model_supports!("qwen/qwen3.7-max", param::toolz);

error: unknown OpenRouter capability `param::toolz`; did you mean `param::tools`?

Capability not supported by the model:

const MODEL: &str = model_supports!("qwen/qwen3.7-max", input::image);

error: OpenRouter model `qwen/qwen3.7-max` does not support required capability(s): input::image
