Lataa Token Use 1.2.3

tokenuse 1.2.3, named Back Pay, teaches the pricing books about Claude Opus 5 and then settles the bill for the calls that were already made. Opus 5 matched no pricing row until now, so every Opus 5 call quietly fell through to the Claude Sonnet 4.6 fallback and was billed at $3/$15 per MTok instead of $5/$25 — an under-count of roughly 40% that no warning surfaced, because an unpriced model is indistinguishable from a cheap one once the fallback has done its work. This release prices the model properly, names it across every surface, and includes a one-shot archive repair that puts the missing cost back into history.
Highlights
- Claude Opus 5 is priced and named: $5/MTok input and $25/MTok output, with 5-minute cache writes at $6.25, cache reads at $0.50, and fast mode at 2x base. It appears as "Opus 5" in the Opus family across the dashboard, reports, and model pages.
- History is repaired automatically: archive schema v8 corrects Opus 5 costs already frozen into archive.db, once, the first time this version starts. Existing Opus 5 totals will rise; nothing else is touched.
- Copilot coverage too: GitHub's Opus 5 rate is tracked under the copilot tool scope, alongside the existing per-provider Copilot rows.
- A broken pricing refresh is fixed: Cursor restructured its documentation and removed the table the refresh keyed on, which was failing the entire refresh run rather than just that one source.
Opus 5 pricing
The curated Anthropic rows now carry Claude Opus 5 with a 2x fast_multiplier, matching Claude Code fast mode's published $10/$50 per MTok. The LiteLLM import needed no change: the existing claude-opus- filter picked up claude-opus-5 and its Bedrock and Google Cloud regional variants on the next refresh. The shared model registry gains an Opus 5 rule ahead of the claude-opus-4* prefixes, so the point-release-free id is not shadowed by its predecessors, and dated or vendor-prefixed ids fold into it as usual.
Claude Opus 4.7 fast mode was removed upstream on July 24, 2026. Its 6x fast_multiplier row is deliberately kept so archived fast-mode calls from before the removal still price correctly.
Repairing archived costs
Archived costs are frozen at import time on purpose — the archive inherits import-time cost precisely so that history is never silently repriced — so this correction is a deliberate, versioned migration rather than an ongoing reprice pass. It runs once, gated on the schema version, and cannot re-run.
The repair rescales affected rows rather than recomputing them. Opus 5's input, output, cache-write, and cache-read rates are each exactly 5/3 of the Sonnet 4.6 rates the calls were charged at, so a single factor restores the true cost. That approach is not just simpler than a recompute, it is more accurate: the 1-hour cache-write premium scales with the cache-write rate but is never persisted on the row, so a recompute would silently drop it. Web-search requests bill at $0.01 under both rows and are held out of the rescale, and speed = 'fast' rows additionally pick up the 2x multiplier the fallback row never carried.
Every row is checked before it is touched. A row whose stored cost already reflects Opus 5 pricing is skipped, so anyone who downloaded corrected pricing books before upgrading the binary cannot be double-charged. Model ids are matched through the shared canonicalization, so dated and vendor-prefixed ids are included while a distinct neighbour such as claude-opus-5-fast is not.
Pricing refresh maintenance
Cursor folded its standalone "Auto pricing" table into the combined "Model pricing" table on the same documentation page. Because a markdown source whose heading no longer exists fails the whole refresh rather than only its own rows, this had taken --refresh-prices out of service entirely. Cursor Auto is now read from that table's Auto Cost row; its rates are unchanged at $1.25 input and cache write, $0.25 cache read, and $6 output.
Upgrade notes
- The archive schema moves from v7 to v8. The migration runs on first launch and rewrites only the cost of Opus 5 calls that were priced at the fallback rate; no table, column, or row is added or removed.
- Expect Opus 5 spend to increase across every period that contains Opus 5 usage. This is the correction, not new usage.
- Older binaries can still open a v8 archive: the schema is unchanged, so only the corrected cost values differ.
- Pricing books downloaded through the Config page are separate from the books embedded in the binary and take precedence over them. Re-download them after upgrading, or newly ingested Opus 5 calls will keep using the stale rates.
- Local usage analysis remains local. Network use stays limited to confirmed Config-page downloads, opt-in quota sync, Windows/Linux update checks, and maintainer refresh or release paths.
- The release tag should be v1.2.3 and must match the root Cargo package, desktop Cargo package, desktop package.json, and Tauri config versions.
