Free AI Chat Assistants: Free Tiers, Limits

Free AI Chat Assistants

30 resources

Chat collects assistants you can hold a conversation with: general chatbots, role and character playgrounds, long-document readers, and the APIs that serve the same capability. Coding-specific assistants live under Coding, while anything whose main job is driving other software sits under Agents. Free access here is mostly a cap per window — a number of replies every few hours, or a token budget that resets daily — rather than a countdown. Access tells web-only products from ones issuing a key; Type splits permanent tiers from sign-up promotions.

Web version free; flagship models have request limits (see the site for details)
API new-user free quota Each model gets its own bonus quota (typically 1,000,000 tokens per model; quotas are per-model, not transferable). Validity is usually 90 days but the start point differs: models already released count from account activation, models released later count from their release date. Expired quota is void and never reissued or extended, and re-registering under the same verified entity does not grant it again.
