feat: Make Sonnet 4.6 free for one week in review mode by kiloconnect[bot] · Pull Request #295 · Kilo-Org/cloud

kiloconnect · 2026-02-17T18:59:58Z

Summary

Make Claude Sonnet 4.6 (claude-sonnet-4-6-20250514) free for one week in Code Reviewer (review mode).

Promotion window: 2026-02-18 00:00 UTC → 2026-02-25 00:00 UTC (7 days)

Changes

Free model promotion (following PR #27 patterns)

Add sonnet_46_free_review_model in src/lib/providers/anthropic.ts with review_only: true flag
Extend KiloFreeModel type with review_only, promotion_start, and promotion_end fields
Register the model in kiloFreeModels array in src/lib/models.ts
Hide review-only models from the public model list (same pattern as slackbot_only)
Block access to review-only models outside of internal API (Code Reviewer) and outside the promotion window

Promotion-aware model selection

Add getDefaultCodeReviewModel() function that returns the promotional model during the active window
Update prepare-review-payload.ts to use the promotion-aware model selection
When no custom model is configured, code reviews automatically use Sonnet 4.6 during the promotion

Tracking & Reporting

Structured logging: Log when the promotional model is selected for a code review (includes reviewId, owner, promotion dates)
Admin endpoint: New getReviewPromotionStats tRPC query in the admin code reviews router that reports:
- Total/completed/failed reviews using the promo model
- Unique users and organizations
- Daily breakdown with per-day user counts
- Promotion active status
Helper functions: isReviewOnlyModel(), isReviewPromotionActive(), getActiveReviewPromotionModel()

Access control

Review-only models return "model does not exist" when accessed outside of Code Reviewer (internalApiUse)
Promotion automatically expires — after promotion_end, the model returns "does not exist"
No changes needed to billing: code reviews already use skipBalanceCheck: true

Files changed

src/lib/providers/kilo-free-model.ts — Extended type with review_only, promotion_start, promotion_end
src/lib/providers/anthropic.ts — Added sonnet_46_free_review_model definition
src/lib/models.ts — Registered model + added helper functions
src/lib/providers/openrouter/index.ts — Filter review-only models from public list
src/app/api/openrouter/[...path]/route.ts — Access control for review-only models
src/lib/code-reviews/core/constants.ts — Promotion-aware getDefaultCodeReviewModel()
src/lib/code-reviews/triggers/prepare-review-payload.ts — Use promotion model + tracking logs
src/routers/admin-code-reviews-router.ts — getReviewPromotionStats admin endpoint

Testing

TypeScript type checking passes
No snapshot changes (review-only models are hidden from public model list)

src/lib/code-reviews/core/constants.ts

+ */
+export function getDefaultCodeReviewModel(): string {
+  const promoModel = getActiveReviewPromotionModel();
+  return promoModel?.internal_id ?? BASE_CODE_REVIEW_MODEL;


CRITICAL: getDefaultCodeReviewModel() returns internal_id instead of public_id, which means the promotional model will not be recognized as free by the API route.

The API route at src/app/api/openrouter/[...path]/route.ts uses the model ID to check isFreeModel(), isReviewOnlyModel(), and isRateLimitedModel() — all of which match against public_id. The applyProviderSpecificLogic() function in src/lib/providers/index.ts:243 then rewrites requestToMutate.model from public_id → internal_id before sending to OpenRouter.

By returning internal_id here, the model bypasses the review-only access gate and isn't recognized as free, so users will be charged credits for what's supposed to be a free promotional model.

For reference, the Slack integration correctly uses public_id (opus_46_free_slackbot_model.public_id) in src/lib/integrations/slack-service.ts:20.

Suggested change

return promoModel?.internal_id ?? BASE_CODE_REVIEW_MODEL;

return promoModel?.public_id ?? BASE_CODE_REVIEW_MODEL;

+        and(
+          gte(cloud_agent_code_reviews.created_at, promoStart),
+          lt(cloud_agent_code_reviews.created_at, promoEnd),
+          eq(cliSessions.last_model, promoModelId)


WARNING: This query matches last_model against promoModel.internal_id. If the critical bug in getDefaultCodeReviewModel() is fixed to return public_id instead of internal_id, then last_model in the DB will store the public_id (e.g. anthropic/claude-sonnet-4-6-20250514:review), and this query will need to match on public_id as well.

Consider using promoModel.public_id here to stay consistent with the fix, or add a comment clarifying which ID format last_model stores.

Overview

Severity	Count
CRITICAL	1

SUGGESTION	0

Issue Details (click to expand)

CRITICAL

File	Line	Issue
`src/lib/code-reviews/core/constants.ts`	25	`getDefaultCodeReviewModel()` returns `internal_id` instead of `public_id` — the promotional model won't be recognized as free by the API route, causing users to be charged credits

WARNING

File	Line	Issue
`src/routers/admin-code-reviews-router.ts`	399	Admin stats query matches `last_model` against `internal_id`; if the CRITICAL fix switches to `public_id`, this query will also need updating

Other Observations (not in diff)

Issues found in unchanged code that cannot receive inline comments:

File	Line	Issue
`src/lib/models.ts`	56	`isRateLimitedModel()` excludes `slackbot_only` but not `review_only` models — the review-only promo model will be subject to the standard free-model IP rate limiter, which may not be desired since it's accessed via `internalApiUse` (code reviewer)
