Cost was previously computed with a single flat rate (Sonnet-based claudeStatus.pricing.* defaults) regardless of which model produced each entry, overestimating Haiku usage ~3x and underestimating Opus usage up to 5x. Each JSONL entry carries message.model, so price entries by it. - jsonlReader: built-in per-model rate table (Fable/Mythos 5, legacy Opus <=4.1, Opus 4.5+, Haiku, Sonnet) with resolveModelPricing() and entryCost(); UsageEntry gains a model field - New setting claudeStatus.pricing.useModelPricing (default true); unknown models and disabled mode fall back to manual pricing.* rates - All cost consumers (readAllUsage, projectCost, prediction, heatmap) now take CostOptions from config; prediction and heatmap previously ignored user pricing settings entirely and always used defaults - AggregatedUsage gains costByModel5h; dashboard token breakdown lists per-model 5h cost - l10n: EN/JA/ZH for the setting description and dashboard label - Docs: DATA.md pricing tables, SETTINGS.md, README (EN/JA/ZH), CHANGELOG - Tests: rate resolution, fallback, entryCost toggle, model parsing Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012ZLCLQeudf1LQBnBSyyr4f

Summary
Costs were computed with one flat rate — the Sonnet-based
claudeStatus.pricing.*defaults — regardless of which model produced each entry. That overestimates Haiku 4.5 usage ~3× and underestimates Opus usage up to 5×. Every JSONL entry carriesmessage.model, so this PR prices each entry by its model.Changes
Built-in per-model rates (
resolveModelPricing()injsonlReader.ts, first match wins, per 1M tokens; cache read = 0.1× input, cache write = 1.25× input per Anthropic's published pricing):fable,mythosclaude-3-opus,opus-4-0/1,opus-4-2025opushaikusonnetclaudeStatus.pricing.useModelPricing(boolean, defaulttrue). Unrecognized models (e.g.<synthetic>) — and every entry when disabled — fall back to the manualclaudeStatus.pricing.*rates, so the old behavior is one toggle away.CostOptions:readAllUsage,projectCost,prediction,heatmapnow takeconfig.costOptions. This also fixes a pre-existing inconsistency: prediction and heatmap previously ignored the user'spricing.*settings and always used the hardcoded defaults.sonnet-4-5: $0.42,haiku-4-5: $0.03), fed by a newcostByModel5haggregate.package.nls*+l10n/bundle.l10n.*).docs/DATA.md(model-aware + manual pricing tables),docs/SETTINGS.md, README settings tables (EN / JA / ZH), CHANGELOG.Tests
New suites cover rate resolution per family (including the legacy-Opus-before-generic-Opus ordering), fallback for unknown/missing models, the
useModelPricingtoggle inentryCost, andmodelparsing inreadUsageEntries.npm run lint✅,npm run compile✅, unit suites (43 tests) ✅ via mocha;@vscode/test-electroncannot download VS Code in this sandbox — please rely on CI for the extension-host suites.Note: since costs are estimates, displayed totals will change for users mixing models (they become more accurate). Called out in the CHANGELOG.
