tinker.types.ClientConfigResponse

class tinker.types.ClientConfigResponse( BaseModel)

Server-side feature flags resolved for this caller.

Uses BaseModel (extra="ignore") so new flags from the server are silently dropped until the SDK adds fields for them.

Fields:

• pjwt_auth_enabled ( bool)
• credential_default_source ( str)
• sample_dispatch_bytes_semaphore_size ( int)
• inflight_response_bytes_semaphore_size ( int)
• parallel_fwdbwd_chunks ( bool)
• proto_write_fwdbwd ( bool) – When true, the SDK serializes ForwardBackwardRequest as proto bytes and POSTs with Content-Type: application/x-protobuf. Falls back to JSON when false (default) or when the request can't be encoded in proto.
• proto_compress_fwdbwd ( bool) – When true (and proto_write_fwdbwd is also true), the SDK zstd-compresses the proto fwd/bwd request body and sets Content-Encoding: zstd. Real fwd/bwd payloads compress >10× — the API server decompresses transparently via an ASGI middleware. Ignored on the JSON path.
• fwd_via_fwdbwd ( bool) – When true (and proto_write_fwdbwd is also true), TrainingClient.forward() routes through /api/v1/forward_backward with forward_only=True on the proto instead of /api/v1/forward. Ignored when proto_write_fwdbwd is false (the JSON /forward path remains).
• billing_exception_max_pause_duration_sec ( int)
• sample_no_retries ( bool)
• sample_enable_stuck_detection ( bool) – When true, the SDK runs the retry handler's progress timeout check that raises APIConnectionError("...Requests appear to be stuck.") when no progress is made within RetryConfig.progress_timeout.
• sample_max_concurrent_requests ( int) – Maximum number of in-flight sampling requests a SamplingClient will allow (the size of its retry handler's semaphore). Always applied as the sampling RetryConfig.max_connections, overriding any value in a caller-provided retry_config.
• use_pyqwest_transport ( bool) – When true, the SDK builds its default httpx async client on top of the pyqwest (reqwest/hyper-based) transport adapter. Set to false server-side to force every client to fall back to httpx's default transport.
