Create Batch
Create a batch job.
Accepts requests inline — no separate file upload step required.
Model and provider are resolved from body.model across all requests;
all requests must target the same model.
Returns 429 (batch_limit_exceeded) if the owner already has 10 or more batches in a non-terminal state. Returns 501 (not_implemented) if the resolved provider doesn’t support batch.

Headers
Dated version of the API contract to pin this request to. Omit it and the request is served under 2026-08 — the oldest supported version, so an existing integration is never moved by a release. A malformed or unsupported value is rejected with 400 invalid_api_version rather than falling back silently. The version actually served is echoed as X-Mesh-Version on every response, including errors.
