Claude pricing is the most legible of the big three: Haiku 4.5 at $1 input / $5 output per 1M tokens, Sonnet 5 at $2 / $10, Opus 5.5 at $4 / $20, and the Mythos-class Fable 5.1 at $10 / $50. Opus 5.5 (September 2026) cut the Opus rate from $5 / $25 to $4 / $20, and Sonnet 5’s $2 / $10 launch price is now permanent. All current models offer at least 200K context, with the frontier models at 1M.
Claude is also the only one of the big three with no long-context surcharge: the full 1M-token window on current models bills at standard rates, where GPT charges 2× input beyond 272K tokens and Gemini 2× beyond 200K. For huge-prompt workloads, that quietly flips the price comparison.
Prompt caching is explicit rather than automatic: you mark cache breakpoints, pay 1.25× input to write a prefix into the five-minute cache (2× for the one-hour cache), then read it back at a fraction of the fresh-input price — a tenth on most models, and far less on the newest: Opus 5.5 reads at $0.20 (5% of input) and Fable 5.1 at $0.25 (2.5%). For long system prompts and tool definitions, reads dominate writes and the net saving is dramatic.
The Batch API halves both input and output prices for asynchronous jobs, and it stacks with cache pricing — batched, cached input on Sonnet 5 costs pennies per million tokens.
Claude bills per token with separate input and output rates per million tokens: Haiku 4.5 at $1 / $5, Sonnet 5 at $2 / $10, Opus 5.5 at $4 / $20, and Claude Fable 5.1 at $10 / $50. Cache reads cost a tenth of fresh input on most models — and just 5% on Opus 5.5 and 2.5% on Fable 5.1.
Claude Haiku 4.5 at $1 input / $5 output per 1M tokens ($2/1M blended). It supports the same tool use, vision, and reasoning surface as its bigger siblings with a 200K context window — the default pick for high-volume production traffic on Claude.
You set cache breakpoints on stable prompt prefixes. Writing a prefix to the cache costs a small premium over the normal input rate; every subsequent request that reuses it pays the cache-read rate — roughly 10× cheaper, and 20–40× on Opus 5.5 and Fable 5.1 — until the cache expires. Apps with long system prompts, RAG contexts, or big tool definitions save the most.
Tier for tier, mostly yes since GPT-6: Opus 5.5 ($8/1M blended) vs GPT-6 Sol ($4), and Haiku 4.5 ($2) vs GPT-6 Luna ($0.20) at the small end. At the top, Fable 5.1 and GPT-6 Astra are priced identically at $10 / $50, and Sonnet 5 ($4) matches GPT-6 Sol. On prompts past ~272K tokens the gap narrows, because GPT bills 2× input beyond that threshold and Claude doesn’t. The matchup table below puts all three vendors side by side.
No — API usage is pay-as-you-go. Claude.ai consumer subscriptions (Pro, Max) are a separate product and include no API credits.
