GPT-5.6 Sol comparability rate on ChatGPT Plus, Pro 5x and Pro 20x stored at $2.00 / $10.00 per 1M (cached read $0.20) → GPT-5.6 Sol comparability rate $4.00 / $20.00 per 1M (cached read $0.40, cache write $5.00) — the vendor’s own Standard row
Rate-provenance correction: OpenAI’s pricing page headlines gpt-5.6-sol in its Standard table at $4.00 input / $20.00 output per 1M with cached input $0.40 and cache write $5.00, and notes that this promotional pricing is available at least through November 21, 2026. The $2.00 / $10.00 figure these three consumer rules carried is the page’s Batch and Flex tariff, byte-identical to its gpt-6-sol row. Measured: cost per request $0.0131 -> $0.0262, halving Sol’s Req/$1 on Plus (76 -> 38), Pro 5x (76 -> 38) and Pro 20x (76 -> 38).
