fix: claude-sonnet-5 intro pricing 2/10 (0.39.20) - #17
Merged
Conversation
Dashboard overstated Claude Sonnet 5 cost by 50%. Anthropic's official
intro price is 2/10 USD/MTok (cache_read 0.20, cache_write 2.50) through
2026-08-31; sticker is 3/15. The bundled LiteLLM seed already carries the
intro rate, but a curated exact pin + 5 edge-patch tables forced 3/15.
- Drop the curated exact `claude-sonnet-5` pin (+ its now-dead fuzzy rule):
the src path falls through to the seed's exact entry (matcher step 2) at
2/10 and will auto-track LiteLLM's revert to 3/15 after the intro window,
no manual edit needed.
- Update the 5 dashboard/edge-patches MODEL_PRICING tables to 2/10 (edge
patches don't read the seed). These are hardcoded and must be reverted
manually after 2026-08-31 — dated reminder added to curated-overrides
_meta.sonnet5_intro_price_expiry (mirrors the deepseek expiry convention).
- Regression tests: pricing.test.js asserts claude-sonnet-5 resolves to
2/10 (computeRowCost 3.725, not 5.5875); edge-patch-pricing-sync asserts
the parsed value equals 2/10/0.2/2.5 across all 5 tables.
- Version bump 0.39.19 -> 0.39.20 (source only; npm publish separate).
Verified: getModelPricing('claude-sonnet-5')=2/10 against real seed;
node --test 55/55, vitest 7/7, validators clean.
Closes #16
