2026-10-13-pi-coding-agent-prompt-length-pricing-tiers-stop-disappearing-from-model-cost-estimates

Prompt-length pricing tiers stop disappearing from model cost estimates. Model-catalog loaders preserve prompt-length pricing tiers for OpenCode, OpenCode Go, OpenRouter, Vercel AI Gateway, Google, MiniMax, and other models.dev providers. Dropping those tiers undercounted some long-prompt costs. OpenRouter time-of-day overrides are still not modeled.

Channel: tagged-release. Half: defect. Date: 2026-10-07.

Operator consequence: Rebaseline long-context cost comparisons with 1.1.0 or newer accounting. Distinguish a corrected estimate from a provider price change or proof of the final bill.
