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.

/**
|
|
* model-pricing.ts — single source of truth for paid cloud CHAT/completion
|
|
* model pricing (USD per 1M tokens, input | output).
|
|
*
|
|
* Every chat-pricing site in the codebase derives its numbers from this table:
|
|
* - anthropic-pricing.ts (bare-keyed Anthropic view + estimateMaxCostUsd)
|
|
* - takes-quality-eval/pricing.ts (curated fail-closed allowlist)
|
|
* - eval-contradictions/cost-tracker.ts (silent-Haiku-fallback view)
|
|
* - cross-modal-eval/runner.ts (multi-provider eval panel)
|
|
* - skillopt/preflight.ts (Sonnet-fallback warn-only estimate)
|
|
* The bare-keyed `ANTHROPIC_PRICING` view is itself consumed by budget/budget-tracker.ts,
|
|
* minions/batch-projection.ts, and cycle/budget-meter.ts — so those inherit canonical too.
|
|
*
|
|
* The dollar amounts live HERE ONCE — update prices in this file only. Each
|
|
* consumer keeps its own key allowlist and miss-handling policy (fail-closed
|
|
* vs warn-only vs null); this module owns the values, not the policy. Because
|
|
* every other table is DERIVED from this one (not a hand-copied duplicate),
|
|
* cross-table price drift — the kind that left Opus 4.7 at $15/$75 in one table
|
|
* for months — is structurally impossible. test/model-pricing.test.ts pins that:
|
|
* its "drift guard" asserts each derived view still equals canonical (a
|
|
* regression trip-wire if anyone later re-hardcodes a view back into a duplicate)
|
|
* and that the cross-modal panel models are all present in canonical.
|
|
*
|
|
* Prices verified 2026-06-03 against published provider pricing:
|
|
* - Anthropic: https://platform.claude.com/docs/en/about-claude/models/overview
|
|
* - OpenAI: https://openai.com/api/pricing
|
|
* - Google: https://ai.google.dev/gemini-api/docs/pricing
|
|
* The dream-budget audit JSONL snapshots the rate per call, so historical
|
|
* estimates stay reproducible even after this table changes.
|
|
*
|
|
* Scope: PAID CLOUD chat models only. Free/local providers (llama-server,
|
|
* zero-cost rerankers) are intentionally absent — callers treat those as
|
|
* zero-cost elsewhere. Embeddings live in embedding-pricing.ts (different unit:
|
|
* per-MTok, char-based).
