About Perf
Perf is a single API endpoint that automatically picks the best LLM for each request and guarantees valid JSON output. You call perf.chat(messages) and it handles everything - classifies the task, routes to the cheapest model that can handle it (GPT-4o, Claude, Haiku, etc.), validates the output, and retries if needed. No more JSON parsing failures. No more overpaying for simple tasks. No more writing routing logic yourself.

Ran 500 prompts through Perf: 100% valid JSON, 90% cheaper than GPT-4o baseline. Excited to get this out to those tired of JSON validation errors.
