Cloudflare AI gateway

Cloudflare AI Gateway sits in front of provider APIs and lets you add analytics, caching, and controls. For Anthropic, OpenClaw uses the Anthropic Messages API through your Gateway endpoint.

When thinking is enabled for Anthropic Messages models, OpenClaw strips trailing assistant prefill turns before sending the payload through Cloudflare AI Gateway. Anthropic rejects response prefilling with extended thinking, while ordinary non-thinking prefill remains available.
