Providers
Provider capability evidence
Separate declared support from verified provider behavior.
Provider capability metadata advertises expected support. Live behavior depends on adapter version, chosen model, account access and endpoint configuration.
Read the declared capabilities
- Core provider metadata and negotiation
- TypeScript provider registry and family registrations
- Native provider adapters

| Capability | Evidence to retain |

| Tool calling | Tool-call arguments, correlated execution result, final response |
| Streaming | Ordered chunks, terminal state, cancellation and error paths |
| Structured output | Validated output against the requested schema |
| Multimodal input | Supported content type and an actual provider result |
| Usage | Provider usage metadata and SDK aggregation |
| Sessions | Authentication/session state and recovery behavior |
This page intentionally makes no provider-wide live availability or performance claim. Read the provider's current catalog and keep exact model identifiers in deployment configuration rather than timeless quickstart text.
