Anthropic's Claude API is per-token with no free tier: Fable 5.1 $10/$50, Opus 5 $5/$25, Sonnet 5 $2/$10 and Haiku 4.5 $1/$5 per 1M in/out, with the full 1M-token context at standard pricing on 4.6+, a 50% batch discount, prompt-caching reads at 0.1× input (0.025× on Fable 5.1), 1.1× US-only inference, and itemized server-tool pricing. Consumer plans (Free/Pro/Max) are a separate product.

No free tier on the API (verified 2026-09-16) — first requests bill at per-token rates. The claude.ai Free plan is a separate consumer product with usage limits, not API access.

Claude's consumer app is sold on a plan matrix published at anthropic.com/pricing. The Free column includes chat on web, iOS, Android and desktop, Sonnet and Haiku model access, a 200k-token context window, web search, artifacts, memory, skills, connectors, voice mode, incognito chats and file creation and editing through code execution, while Opus, Fable, Claude Code, Projects, Research, Claude in Chrome and the Microsoft 365 and Outlook integrations are all marked as not included. Anthropic states only that usage limits apply and does not publish a numeric message or token cap for the Free plan.

No free tier stated on official pages (checked 2026-09-16) as a credit: the consumer Free plan is a listed plan tier but no allowance or numeric cap is published, and the API docs state only that new API users receive a small amount of free credits without quantifying them.
