  "claim": "A 32×32 jev-paint painting is between 1 and 8 Jev requests and roughly 1,000 to 3,100 typed questions, for about a fifth of a US cent to a bit over one cent. The request and question counts are exact — they come from running jev-paint's own buildRequests() offline. The cost is an estimate, because the request bodies were never sent: the token counts are inferred from a characters-per-token ratio calibrated on a different project's recorded Jev usage.",
  "method": "Ran jev-paint's web/jev.mjs buildRequests(prompt, method, 32) in Node and counted the returned batches and questions directly. Serialized each batch with JSON.stringify and counted characters. Converted characters to input tokens using the 2.726-3.444 chars/token band measured over the 226 recorded Jev requests in openroboto-ai/jev-robot-control (which log both the exact request payload and the API's own input_tokens). Priced at $0.042 per 1M input tokens, output free, which is the rate that fits those 226 recorded (input_tokens, output_tokens, cost_usd) triples to the cent.",

  "note": "Latency is NOT estimated here and no wall-clock claim is made: nobody has published a Jev latency figure for a 27k-token request, and these bodies were never sent. Four requests run concurrently, so an 8-request painting is two waves. The prompt used for sizing is jev-paint's own committed sunflower fixture prompt; a longer prompt shifts every row up slightly because the state block is repeated in every batch.",
