OVHcloud AI Endpoints (no-signup anonymous free tier)

Callable anonymously with no registration and no API Key required (rate-limited by IP + model); registering and generating an API Key raises the rate limit, with 20+ open-source models hosted in European data centers, OpenAI SDK compatible

Third-party hands-on testing puts the anonymous Playground tier at roughly 2 RPM per IP per model (the official page doesn't disclose an exact figure, only that it's 'rate-limited by IP, by model'); once registered, the API Key's rate limit is raised separately per Public Cloud project and model, again without an official published figure. There's also a separate Public Cloud new-customer trial: a $200 general-purpose cloud credit valid for 1 month, requiring a valid payment method to claim — a different thing from the anonymous/registered 'AI Endpoints free access' tiers described here; don't confuse the two.

⚠️One of the lowest-friction entries in this category — the anonymous tier doesn't even require registering an account; just take the API endpoint and call 20+ open-source models directly, including Qwen, Mistral, Llama, and DeepSeek — well-suited to quick verification or lightweight scripts. The rate limit is conservative (community testing puts it around 2 RPM per IP per model), unsuited to high-frequency production use; heavy use requires registering to unlock a higher rate limit, or switching to the paid/large-credit options elsewhere in this list. Data is hosted in the EU, a plus for scenarios sensitive to European privacy compliance.
