Anthropic Claude models in ClawAI

What the Claude lineup covers

Anthropic’s current lineup has three tiers: Claude Opus 4 at the top, built for the hardest and most involved tasks; Claude Sonnet 4 as the general-purpose middle tier; and Claude Haiku 4.5 as the fast, lower-cost option for simpler requests. ClawAI’s router can move between them per request.

When a task suits a Claude model

Claude models are commonly used for long-document work, careful step-by-step writing, and coding assistance where following detailed instructions matters. As with any provider, the right model for a specific task is something worth verifying against your own workload — see how to read AI benchmarks below for what a published number does and does not tell you.

How ClawAI routes to it

ClawAI’s router can send a request to a Claude model automatically under Auto, High Reasoning or Cost Saver routing, or you can pin one under Manual Model mode. Anthropic is the only provider in this list that publishes a separate cache-write rate, which is a billing detail rather than a capability difference — it does not change what the model can do.

Questions people ask

What is the difference between Opus, Sonnet and Haiku?

They are three cost and capability tiers of the same model family — Opus is the highest tier, Sonnet the mid tier, Haiku the fastest and lowest-cost tier. ClawAI’s router can pick between them, or you can choose manually.

Does ClawAI have a direct partnership with Anthropic?

No. ClawAI connects to Anthropic’s public API the same way any application with an API key would.

Is Claude Opus 4 available on every plan?

Model availability is enforced by your plan and the live catalog, not by this page. Confirm the current lineup on the pricing page before choosing a plan for a specific model.
