Claude Sonnet 4.6 Is Here — Free Upgrade for All Agents

Anthropic just released Claude Sonnet 4.6, the successor to Sonnet 4.5 — and starting today, all new agent deployments on Clawly will use it by default.

What's new

Sonnet 4.6 is a drop-in upgrade over Sonnet 4.5. It delivers stronger reasoning, better instruction following, and improved tool use — all at exactly the same token pricing ($3 per million input tokens, $15 per million output tokens). You're getting a more capable model for the same cost.

What this means for you

• New agents deployed from today onward will automatically use Claude Sonnet 4.6 on both Managed and BYOK plans.
• Existing agents running Sonnet 4.5 will continue to work. If you'd like to upgrade, simply redeploy your agent from the dashboard — your config, channels, and workspace will carry over.
• Pricing stays the same. Whether you're on BYOK or Managed, token rates are identical to Sonnet 4.5. No plan changes needed.

Why we default to the latest

Part of the value of a managed hosting platform is that you don't have to chase model updates yourself. When a better model ships at the same price, we move new deployments to it so you're always getting the best available performance. You can always pin a specific model version in your agent config if you prefer stability over freshness.

Try it out

Head to your dashboard and deploy a new agent, or redeploy an existing one to pick up Sonnet 4.6. You should notice improvements in multi-step reasoning, tool use accuracy, and overall response quality.
