Expand description

Static capability advertisement returned by provider implementations.

Fields§

§chat: bool

Provider can return a complete chat response.

§chat_stream: bool

Provider can stream chat events.

§tool_calling: bool

Provider accepts tool definitions in chat requests.

§parallel_tool_calls: bool

Provider can execute or request multiple tool calls concurrently.

§json_schema_output: bool

Provider can constrain output with a JSON schema.

§vision: bool

Provider can consume image content.

§embeddings: bool

Provider can produce embeddings.

§max_input_tokens: Option<u32>

Maximum supported input tokens, when known.

§max_output_tokens: Option<u32>

Maximum supported output tokens, when known.

§prompt_caching: bool

Provider supports prompt caching.

false for providers with no caching (e.g. local models without a cache layer). true for providers that either accept explicit cache markers (Anthropic) or perform automatic prefix caching (OpenAI, DeepSeek).

§max_cache_breakpoints: Option<u8>

Maximum number of cache breakpoints the provider accepts.

Some(4) for Anthropic (which permits up to four cache_control markers per request). None for providers that perform automatic caching without an explicit breakpoint concept (OpenAI, DeepSeek).

§cache_ttl_options: Vec<CacheTtl>

Cache TTLs the provider supports.

Empty for providers with automatic caching. Non-empty for Anthropic ([FiveMinutes, OneHour]).
