Provider-wide limits

• Limits, in the vendor’s words: 50 credits/month per account

Requires social login or AWS Builder ID. Credits do not roll over. Free requests are served from the US and AWS GovCloud is excluded. The docs’ Free column determines model eligibility; newer Sonnet, Opus, Haiku and GPT tiers marked paid are outside the Free allowance.

• No API endpoint to paste: this row is a tool you install or sign in to.
• What you send may be used to train or improve models unless you turn that off (the vendor’s words).
