Capture complete calls
Inspect supported messages, completions, usage, latency, application identity, and route reasons.
// Anthropic-compatible integration
Observe Claude workloads without starting over.
Send supported Anthropic Messages traffic through Punk to establish a workload-specific record of model behavior, cost, latency, policy, and routes. Start observe-only so the live model remains authoritative.
Punk is an independent infrastructure product and is not affiliated with Anthropic. Model names and product marks belong to their respective owners.
// the useful first result
See the workload before optimizing it.
Separate work types
Find repeated request families and isolate novel or consequential work that should remain live.
Test only candidates
Replay and shadow scoped alternatives instead of making a blanket claim about model interchangeability.
// adaptive runtime role
Keep model quality where reasoning is needed.
The goal is not to replace Claude everywhere. It is to learn which requests still deserve live reasoning and which repeated patterns may earn a governed, verified route.
Good candidates
- Structured, reviewable classifications
- Stable summaries from authorized context
- Recurring read-only tool plans
- Repeated requests with clear outcome signals
Verify before production
- Streaming and tool-use behavior
- System prompts and content blocks
- Structured output expectations
- Provider-specific features and errors
- Identity and side-effect declarations
Compatibility is scoped. A base URL change can cover supported model traffic. It does not automatically instrument every tool, browser action, approval, or application outcome.
Start with one Claude-powered task.
Confirm supported behavior and trace quality in observe-only mode before expanding the workload.
