Simon Willison found it in the OpenRouter price list. 1.6T MoE, ~49B active, 1M context, up to 384K output, at $0.435/M input (cache miss) and $0.87/M output. The agentic-coding deltas versus the preview are the story: DeepSWE 12.8 → 62.7, CyberGym 52.7 → 83.3, Terminal Bench 2.1 72.1 → 87.9. Near-frontier agent coding at roughly 1/60th of frontier pricing, with a significant API price increase already announced. Willison also notes the three reasoning-effort levels produce visibly different SVG output on his pelican benchmark, which he hasn't seen from other configurable-effort models. Meanwhile the Hugging Face repos still host April preview artifacts and the API endpoint swapped underneath the same model ID: Vercel's AI Gateway picked up new weights by default, so existing code changed silently.
