Agnes AI’s own models behind an OpenAI-compatible API, with its Flash text models charged at zero today and image generation free beside them
agnes-3.0-flash, agnes-2.5-flash
“Is the API free to use? Yes. Our core AI models are free to use indefinitely”, the FAQ says, and the pricing page shows the mechanism: agnes-2.5-flash and agnes-3.0-flash list at $0.05 in / $0.15 out per 1M and are charged $0 — “Cached input, input tokens, and output tokens are currently free for agnes-2.5-flash and agnes-3.0-flash” — while agnes-2.5-pro bills $0.45/$0.90 and the pro beta $0.10/$0.30. The page is candid that the zero is a current price rather than a contract: “Promotional end dates are subject to Agnes AI platform announcements and your account bill”. The ceiling is a rate, not a quota: a key that is neither on a paid Token Plan nor enterprise-verified gets 30 requests a minute allowed and 20 effective on text models (Token Plan FAQ, effective 2026-06-22), and no daily figure is published. Image models are free at every resolution too. The terms are governed by Singapore law. The docs live on wiki.agnes-ai.com. Read 2026-09-14
