Practical rate limiting takes the form of in-app waits during peak demand on the free tier (mitigated by the c.ai+ subscription tier which gets priority access). No formal RPM/TPM developer limits are published. notes: >- Free-tier users see longer wait times during peak load; c.ai+ subscribers get priority. There is no public RPM / TPM specification. sources: - https://character.ai/ responseCodes: throttled: 429 limits: - name: Free-Tier Throttling scope: account metric: in_app_wait limit: variable, peak-load dependent notes: Free users may experience increased wait times for chat responses during peak demand. - name: c.ai+ Priority Access scope: account metric: priority limit: prioritized over free tier notes: c.ai+ subscribers receive priority queuing and faster responses. - name: Developer API scope: not_applicable metric: not_offered limit: not offered notes: Character.AI does not publish a public developer API or its rate limits. policies: - name: Subscribe for Priority description: c.ai+ subscription mitigates wait-times during peak demand. maintainers: - FN: Kin Lane email: kin@apievangelist.com
