hgeldenhuys c683b36d4c fix(model): default to anthropic/claude-sonnet-4.5 — mimo burned its budget on reasoning tokens 
xiaomi/mimo-v2.5-pro is a reasoning model. With max_tokens=6000 it produced 5999 reasoning_tokens and zero actual output (just CSS + empty body). Reasoning models compete with their own output for the token budget — wrong fit for HTML composition.

Sonnet 4.5 is non-reasoning, ~50 tok/s, produces clean structured HTML at 5K-token output sizes. Override via OPENROUTER_MODEL env var.

pitch-builder

Throwaway Kapable App that turns a brief + a client URL into a 2-page A4 client-pitch PDF.

Stack

RR7 + Bun BFF. Single page with a form on the left and an iframe preview on the right. The "Save as PDF" button calls iframe.contentWindow.print() which opens the browser's native print dialog — choose "Save as PDF" with A4 paper size, no margins. No headless Chrome dependency on the server.

Endpoints

  • GET / — form + preview UI.
  • POST /api/compose — body: { clientName, clientUrl?, audience, brief, mode }. Calls OpenRouter, returns { html, elapsed_ms, usage, model }.
  • GET /health — 200 ok.
