DeepSeek V4 metadata now reflects the 2026-08-13 revision. V4 Pro supports low reasoning effort. Both V4 models use the same reasoning-effort mappings, with updated tests.

DeepSeek reasoning effort updates

Layer / File(s)	Summary
Model metadata packages/types/src/providers/deepseek.ts	V4 Pro now supports low. The metadata revision comments use 2026-08-13. Pricing values remain unchanged.
Reasoning-effort normalization and tests src/api/providers/deepseek.ts, src/api/providers/__tests__/deepseek.spec.ts	Both V4 models map low to low, medium/high/xhigh to high, and max to max. Tests cover the updated mappings.

This localized provider-mapping and pricing-date update has no actionable merge-blocking risk remaining beyond normal checks and review.

Review and test-failure triage complete.

• The live PR advanced to 2757402, which independently added the missing model guard and corrected the DeepSeek mapping tests. The focused suite passes with 30 tests passed and 1 skipped.
• I prepared and validated the remaining cleanup locally: remove the unrelated future-dated pricing annotations while preserving the deepseek-v4-pro capability date. The full repository suite passed with 10/10 tasks and 7,370 tests; repository-wide lint and type checks also passed.
• Push is blocked because this is a fork PR (WHMHammer/Zoo-Code:upstream-pr) and GitHub rejected the branch update with permission denied. No review threads were available to resolve.

The remaining action for the contributor is to revert the date-only pricing annotation changes, or grant maintainers write access to the PR branch so the prepared cleanup can be applied.
