| Pollinations.ai no cardno phoneOpenAI-compat | Trial | Quest Pollen: create an account, complete eligible Quests on the Quests dashboard and claim the rewards; Quest Pollen is spent before paid Pollen on regular (non-paid-only) models.

Text, image, video, audio, embeddings and 3D models behind one OpenAI-compatible API | The old anonymous 1 req/15s and Seed 1 req/5s tiers (and the watermark/nologo scheme) are gone from the current docs; the API moved to gen.pollinations.ai with keys from enter.pollinations.ai. Quest availability and reward amounts change ("the dashboard and the linked issue are the source of truth"). No credit card needed to try. Paid-only models require Paid Pollen.

The self-hosted OSS weights carry a separate restriction (research/personal/startups under $2M ARR/funding). Signup does not require a phone number; checked via Google signup flow on 2026-10-02. | 2026-10-02 |
