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.
