Standard on-demand rates from each provider's official pricing page, verified July 2026; figures exclude caching and batch discounts and any long-context surcharges. DeepSeek V4 Pro: Cache-hit input bills at $0.044 per 1M at peak ($0.022 off-peak). Figures use PEAK rates. DeepSeek bills by time of day: peak is 01:00-04:00 and 06:00-10:00 UTC, and off-peak (the other 17 hours) is half these prices. We publish peak so the figure can never understate a bill; halve it for off-peak traffic. Mistral Large 3: Despite the name, Large 3 is priced below Medium 3.5 — it is Mistral's open-weight line; Medium 3.5 is the premium API model. Cached input reads bill at 10% of the input rate, with no cache-creation or storage fee. Price is one input — quality, latency and context limits differ. Confirm live pricing before committing.
