claude-sonnet-5 and claude-fable-5 are GA Anthropic models, but neither
was in CANONICAL_PRICING. A brain routing a tier to them (e.g.
models.tier.reasoning = anthropic:claude-sonnet-5) ran with cost
telemetry blind on that tier: canonicalLookup missed, the budget meter
logged BUDGET_METER_NO_PRICING and disabled the gate, and cost views
under-reported spend.
- model-pricing.ts: anthropic:claude-sonnet-5 at $3/$15 and
anthropic:claude-fable-5 at $10/$50. Sonnet 5's launch intro discount
($2/$10 through 2026-08-31) is deliberately not modeled — the table
carries standard rates so estimates stay conservative and the entry
needs no time-bombed edit when the promo lapses.
- takes-quality-eval/pricing.ts: claude-sonnet-5 added to the curated
SUPPORTED_MODELS allowlist (a likely judge override). Fable 5 stays
out — priced for warn-only consumers, not a budgeted-eval panel model.
- model-pricing.test.ts: pin tests for both rows, matching the existing
Opus 4.8/4.7 pattern. Drift guards iterate the table; no changes.
All derived views (ANTHROPIC_PRICING bare view -> budget-tracker,
batch-projection, budget-meter) pick the rows up automatically.

* fix(pricing): unify chat-model pricing into one canonical source; add Opus 4.8 (#1819)
Single canonical CANONICAL_PRICING table (src/core/model-pricing.ts) with
canonicalLookup; ANTHROPIC_PRICING and takes-quality MODEL_PRICING become
derived views. cost-tracker, cross-modal runner, skillopt preflight, brainstorm
orchestrator, and brain-score all source from it. Adds Opus 4.8 ($5/$25) so
--max-cost-usd and the dream-cycle budget meter enforce on 4.8 runs; fixes a
stale Opus 4.7 $15/$75 in the takes-quality gate and reconciles Gemini 2.0 Flash
to $0.10/$0.40. Because every table derives from canonical, cross-table price
drift is structurally impossible.
* chore: bump version and changelog (v0.42.25.0)
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs: document canonical chat-pricing table for v0.42.25.0
Add KEY_FILES.md entries for src/core/model-pricing.ts (canonical
CANONICAL_PRICING + canonicalLookup) and refresh the now-derived
anthropic-pricing.ts + takes-quality-eval/pricing.ts entries to
current-state. Add the "one canonical chat-pricing table" cross-cutting
invariant to CLAUDE.md. Fix the stale model-price snapshot pointer in
SEARCH_MODE_METHODOLOGY.md (anthropic-pricing.ts -> model-pricing.ts).
Regenerate llms-full.txt.
