Time

Rows with a rate that changes by time of day, promo window or service tier are priced for this scenario instead of their flat listed rate; a brand-colored label under the model name names which one applies. Context size for band-priced rows uses the input-token count below.

Picking a specific hour also previews time-of-day rates that are scheduled but have not started billing yet; those rows are labelled · preview with their start instant. Now only ever shows rates that are billable at this moment.

Flagship (hardest reasoning / coding / agentic). GA 2026-07-09. No longer at parity with OpenAI direct: OpenAI cut Sol to $4.00/$0.40/$20.00 on 2026-08-21 as promotional pricing, and this Foundry meter has not followed — Foundry is 1.25x direct on input and cached input, and 1.50x on output.

Azure Retail Prices API 'Foundry Models' meters (5.6 sol Std Gl, effective 2026-07-01; captured 2026-07-21, re-verified unchanged in a full paged sweep on 2026-08-22 — all sol meters still carry the single 2026-07-01 tranche, with no 2026-08-01 tranche of the kind that carried the Terra and Luna cuts). Cache write bills at 1.25x uncached input ($6.25/M meter); reads stay ~90% off. OpenAI's own rate for gpt-5.6-sol, read via raw DOM from developers.openai.com/api/docs/pricing on 2026-08-22, is $4.00/$0.40/$20.00 with a $5.00/M cache write, labelled promotional and "available at least through November 21, 2026".
