Ten lesser-known or infrastructure-adjacent providers with a verified free allowance, checked on 2026-10-12 across official documentation and focused current references. Quotas come in incompatible units — tokens, requests, neurons, dollars and audio minutes — so they are grouped by tier type rather than ranked on one scale. Two candidates failed verification: Chutes documents no zero-cost tier now, and Pollinations requires an API key with no concrete free allowance stated in its current docs.

Comparison of free AI API allowances excluding mainstream providers, checked 2026-10-12. Built from 23 researched rows across two result sets mixing official documentation (Scaleway, Cloudflare, Hugging Face, Cerebras) with focused current references; 10 providers displayed, the rest kept as validation or negative evidence (OrcaRouter, aggregator proxies, startup-credit programs, Chutes, Pollinations, mainstream providers). Quotas use incompatible units and are quoted verbatim, not converted or scored. Community-sourced limits can change without notice; SambaNova's current signup requirement is unresolved — verify in console.
