Trait Implementations

impl ModelProvider for MetaProvider

fn capabilities(&self) -> &Capabilities

Capabilities the provider advertises. The reducer reads this when building the outgoing ChatRequest (e.g. whether to attach reasoning controls).

fn chat<'life0, 'async_trait>( &'life0 self, request: ChatRequest, ctx: StreamContext, ) -> Pin<Box<dyn Future<Output = Result<FinalResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Stream a chat turn. Typed events flow through ctx.sink; the returned FinalResponse carries token usage and the Anthropic thinking-signature (opaque blob required to continue extended thinking across turns).

fn resolve_context_window<'life0, 'life1, 'async_trait>( &'life0 self, request: &'life1 ChatRequest, ) -> Pin<Box<dyn Future<Output = ContextSizing> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Resolve the effective context window for a turn (what the model will actually enforce). The default returns the static advertised window; Ollama overrides this to probe the model’s real window and auto-fit num_ctx to host memory, honoring the request’s per-model ollama_num_ctx override. None means “let the backend decide”.

fn verify_placement<'life0, 'async_trait>( &'life0 self, current_num_ctx: Option<usize>, ) -> Pin<Box<dyn Future<Output = Option<ModelPlacement>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Best-effort: where the loaded model currently sits in memory. The default returns None (unknown / not applicable); Ollama overrides it to probe /api/ps. Awaited only on the effect runtime, after a turn (when the model is resident), so it never blocks the UI.

fn supports_vision<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Option<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Best-effort: whether the active model can actually see images. None means “unknown / not applicable” — the default for providers that don’t probe, and for cloud providers whose vision support is already known good; Some(false) is what drives the no-vision-model warning. Awaited only on the effect runtime, so a probe never blocks the UI.
