Live latency. Live models.
This table is populated from the service's real /status.json response. Latencies are this-instance p50s since start, not a synthetic promise.

Actually free
Useful limits, stated plainly.
No card. No email. Anonymous access uses a short-lived demo bearer; a revocable durable key doubles the minute rate and gives you a stable identity.

- Exact 500 inference tasks/day for this key
- Also subject to the 5000/day identified-agent limiter
- For embeddings, the exact 500-task quota is the effective daily cap
export BAY_RUN_API_KEY=$(curl -sS -X POST https://run.huggingbay.xyz/v1/keys/free | jq -r .key)What “verified” means
Each embeddings, rerank, and classify response includes a provenance_receipt: a signed envelope binding source commitments, routing and served-model facts, and a semantic output hash. POST /v1/provenance/verify checks that receipt without rerunning inference. It proves receipt integrity and declared execution evidence—not embedding quality, answer truth, or cryptographic attestation of model-weight execution at serve time.

These exact constructor shapes returned 384-dimensional vectors from the live API on 2026-08-18. The model line changes from a proprietary id to Bay Run's pinned open model.
