How we price

Order

Providers are listed cheapest input rate first, then by output rate, a tie going to the creator's own listing. A provider that lists the model without a published rate sits at the end.

Prices

Base-tier, on-demand rates in USD per 1M tokens, converted at ECB reference rates where a provider publishes in another currency. Cached-input and batch rates show only where a provider publishes them. "Cheapest" marks the one provider with the lowest input and output pair; a tie wears no badge.

Cost

Input rate times the input tokens plus output rate times the output tokens, at the monthly volume set above the table. Cached-input, batch, long-context and reasoning-token billing are not modelled.

Transparency and funding

Heads up: Base-tier, on-demand rates per 1M tokens; cached, batch and long-context tiers excluded. A provider may serve a shorter context or a quantized build than the creator's release. Verify before provisioning. More on how we price.

Common questions

What is Claude Sonnet 4 good for?

Coding and reasoning, with a choice of instant or extended thinking. It takes text and images, at the Sonnet tier below Opus.

When is Claude Sonnet 4 not a good fit?

Any new work: Anthropic retired it in June 2026, and Sonnet 4.5 and 4.6 know more recent events. No audio or video input, and closed weights, so no self-hosting.

The cheapest hosted rate is $3.00 / $15.00 per 1M tokens via Replicate.

How does Claude Sonnet 4 compare with Claude Sonnet 4.5?

Anthropic says Claude Sonnet 4.5 improves on Claude Sonnet 4 most in computer use, reasoning and math, and holds focus on long multi-step tasks for many hours. The launch added a memory tool and context editing so agents can run longer. Same price, 200K-token context and text and image input. Claude Sonnet 4 came out 4 months earlier and has a newer knowledge cutoff (March 2025 against January 2025).

Can I self-host Claude Sonnet 4?
