Fixes #1617


Summary by cubic

Fixes #1617 by accounting for Codex cache-write tokens, which were previously ignored and understated usage and cost. Cache-write usage is now parsed, aggregated, priced, and included in table, JSON, unified, and replay output.

  • Adds a Cache Create column to Codex table and JSON reports and includes cache-write tokens in totals.
  • Applies cache-write pricing, including long-context rates, and subtracts cache-write tokens from the reported inputTokens figure.
  • Accepts both cache_write_input_tokens and cache_creation_input_tokens field names from Codex logs.
  • Normalizes cumulative cache deltas so resets and series changes don't produce invalid usage.
  • Keeps daily dates readable in narrow standard and no-cost tables.

Written for commit 7a75b23. Summary will update on new commits.

Review in cubic

Summary by CodeRabbit

  • New Features

    • Added cache-creation token reporting to Codex usage summaries, model breakdowns, totals, and daily reports.
    • Added a “Cache Create” column to usage tables, including long-context usage.
    • Added pricing calculations for cache-creation tokens, including high-volume long-context rates.
  • Bug Fixes

    • Improved separation of cached, cache-created, regular input, and output tokens.
    • Corrected cumulative usage handling and cache-write processing.
    • Improved usage normalization to prevent invalid token totals and ensure accurate costs.

Include Codex cache-write usage in costs, reports, and machine-readable output.

📝 Walkthrough

Walkthrough

The Codex adapter now parses cache-write usage, carries cache-creation tokens through aggregation and long-context buckets, reports them in JSON and tables, and includes model-specific cache-creation cost.

Changes

Codex cache-creation accounting

Layer / File(s) Summary
Usage contracts and normalization
rust/adapters/codex/src/types.rs, rust/adapters/codex/src/parser.rs, rust/adapters/codex/src/replay.rs
Usage structures include cache-creation fields. Raw usage accepts both cache-write field spellings and normalizes their values.
Usage ingestion and deduplication
rust/adapters/codex/src/loader.rs
Deduplication keys include cache-creation tokens. Cumulative usage snapshots produce normalized cache-write deltas.
Aggregation and recorded usage merging
rust/adapters/codex/src/aggregate.rs
Group, model, usage-bucket, long-context, recorded-usage, and parallel-merge paths preserve cache-creation tokens.
Reporting, pricing, and regression coverage
rust/adapters/codex/src/report.rs, rust/adapters/codex/src/lib.rs, rust/crates/ccusage-adapter-all/src/loader.rs, rust/crates/ccusage-adapter-all/src/tests.rs, rust/crates/ccusage-core/src/pricing.rs, rust/crates/ccusage/src/main.rs
JSON and table reports emit cache-creation tokens. Cost calculation uses cache-creation pricing. Tests cover parsing, aggregation, rendering, pricing, and GPT-5.6 Terra output.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 7a75b

The PR adds Codex cache-write token accounting across parsing, aggregation, pricing, and reporting without a concrete merge-blocking risk remaining; it is merge-ready after normal checks and review.

Caution

This PR still drops cache-write tokens from supported API-shaped Codex usage records, so those reports remain undercounted and underpriced.

Reviewed changes This review covers the Codex cache-write parsing, aggregation, replay and deduplication, focused and unified reporting, pricing accessors, table layout, and regression tests.

  • Usage plumbing Added cache-creation counters through raw usage, events, aggregation buckets, replay matching, deduplication, and service-tier accounting.
  • Cost calculation Added normal and long-context cache-creation pricing and excluded cache-write tokens from reported uncached input totals.
  • Report output Populated cacheCreationTokens in focused JSON, tables, and unified rows, while preserving narrow daily date formatting.
  • Validation The focused Codex adapter, unified adapter, core pricing, and formatting checks pass in the pinned Nix shell.

ℹ️ Codex cache-write billing is undocumented

The Codex guide's cost formula still lists only non-cached input, cache reads, and output, and its token mapping omits cache writes. Since this PR changes user-visible totals and costs, the guide should explain cacheCreationTokens, cache-write pricing, and that older logs without the field cannot recover it.

Technical details
# Document Codex cache-write usage

## Affected sites
- `rust/adapters/codex/src/README.md:38-46` — the Codex token mapping omits cache-creation tokens.
- `docs/guide/codex/index.md:46-54` — the Codex cost formula omits cache-write pricing.
- `docs/guide/codex/index.md:84-94` — the Codex JSON section does not identify cache-creation output.

## Required outcome
- Document that Codex `cacheCreationTokens` comes from cache-write usage when present, is priced separately using the model's cache-creation rate, and is unavailable in older logs that lack the source field.

OpenAI Responses-style usage puts cache writes under usage.input_tokens_details.cache_write_tokens, not at the top level. Because the existing headless parser already accepts response.usage, this deserializer silently turns such a supported record into cache_creation_tokens == 0, leaving both cacheCreationTokens and its cost understated.

Technical details
# Preserve nested Responses API cache-write usage

## Affected sites
- `rust/adapters/codex/src/types.rs:256` — `CodexRawUsageFields` has no nested `input_tokens_details` representation.
- `rust/adapters/codex/src/parser.rs:785-807` — headless parsing already selects top-level, `data.usage`, `result.usage`, and `response.usage`.
- `rust/adapters/codex/src/report.rs:111` — reports the resulting zero as `cacheCreationTokens`.

## Required outcome
- Parse `usage.input_tokens_details.cache_write_tokens` for supported headless/API-shaped records and normalize it into `CodexRawUsage.cache_creation_tokens`, while preserving the direct Codex `cache_write_input_tokens` spelling.
- Add a fixture that reaches the nested `response.usage` path and asserts the cache-write tokens affect both output and cost.

## Suggested approach
- Represent `input_tokens_details` in the raw usage deserializer or normalize the nested object before deserialization.

Preserve the public API for non_cached_input_tokens.

No in-repository callers use the former two-argument signature, but the helper is exported and documented as public. Downstream callers with that signature will fail to compile. Preserve the existing function and add a separately named helper for cache-creation tokens.

two-argument non_cached_input_tokens API and keep its existing behavior for
cached input tokens. Move the cache-creation subtraction into a separately named
public helper, updating only the relevant internal calculation to use it so
downstream callers of non_cached_input_tokens remain source-compatible.

Important

The previously reported nested Codex cache-write parsing issue remains unresolved. No additional issues were found in this incremental delta.

Reviewed changes This incremental review covers the Codex normalization, reporting, and regression-test changes since the prior Pullfrog review.

  • Normalized cumulative deltas Clamped cache-read and cache-creation counters after subtraction so reset and series-change snapshots cannot exceed the input delta.
  • Preserved report accounting Applied the normalized cache-creation values through focused and unified reports, table totals, and long-context pricing paths.
  • Added regression coverage Covered cumulative reset and series-change normalization, cache-creation table output, narrow date formatting, unified rows, and pricing accessors.

ccusage performance comparison

PR SHA: 2f2faa6362bc
Base SHA: aa912efb2f35

This compares the Rust PR release binary against the configured base package on the same CI runner.

Package runtime diagnostics

Compares the PR package wrapper, the installed native optional dependency binary, and the workspace release binary on the same large fixture. This identifies whether slow package results come from JavaScript wrapper overhead, the published native binary build, or the Rust core itself.

Fixtures: Claude /home/runner/_work/_temp/ccusage-large-fixture (1.01 GiB, 2597 files), Codex /home/runner/_work/_temp/ccusage-large-codex-fixture (1.01 GiB, 2597 files)
All rows run --offline --json, measured by hyperfine with 0 warmups and 1 runs. This isolates wrapper overhead from the installed native optional dependency and the workspace release binary built on the runner.

Committed fixture performance

Committed small fixtures for stable PR-to-PR feedback and explicit Claude/Codex command coverage.

Fixtures: Claude apps/ccusage/test/fixtures/claude (0.00 MiB, 2 files), Codex apps/ccusage/test/fixtures/codex (0.00 MiB, 1 files)
Base runs the published ccusage package from pkg.pr.new, installed before measurement; PR runs the published native ccusage binary from pkg.pr.new, installed before measurement. Both run --offline --json, measured by hyperfine with 2 warmups and 7 runs.
Peak RSS is measured separately with /usr/bin/time using 1 runs. Lower RSS ratios are better.

Large real-world-shaped fixture performance

Generated fixtures shaped from aggregate local log statistics: thousands of JSONL files, many small sessions, and a long tail of larger sessions. No real prompts, paths, or outputs are stored in the fixtures.

This compares the PR package against the configured base package on the same CI runner.

Package runtime diagnostics

Compares the PR package wrapper, the installed native optional dependency binary, and the workspace release binary on the same large fixture. This identifies whether slow package results come from JavaScript wrapper overhead, the published native binary build, or the Rust core itself.

Fixtures: Claude /home/runner/_work/_temp/ccusage-large-fixture (1.01 GiB, 2597 files), Codex /home/runner/_work/_temp/ccusage-large-codex-fixture (1.01 GiB, 2597 files)
All rows run --offline --json, measured by hyperfine with 0 warmups and 1 runs. This isolates wrapper overhead from the installed native optional dependency and the workspace release binary built on the runner.

Upstream through 8841f92: official Antigravity SQLite adapter (ccusage#1677),
ZCode (ccusage#1675) and Grok Build CLI sources, Copilot session-state usage
(ccusage#1676), Codex originator breakdowns and cache-write token accounting
(ccusage#1663, ccusage#1674), date-window file skipping (ccusage#1665), session totals scoped
to the date window (ccusage#1664), OpenCode v2 session usage (ccusage#1668),
timestamp-aware DeepSeek V4 pricing (ccusage#1679), ETag-validated pricing cache
refreshes (ccusage#1672), and numeric-column preservation in narrow tables
(ccusage#1671).

Conflict resolutions per the personal divergence ledger:

- Antigravity: adopt the upstream native adapter wholesale; remove the
  personal heuristic adapter and the antigravity-analysis/ provenance
  directory.
- Codex: keep counting copied parent history (replay.rs stays deleted),
  keep tier changes applying at the following turn_context, keep the
  pre-v0.144.0 fast windows and the 2x fast-multiplier fallback, and keep
  the append-aware grouped cache with serde'd parser state. Integrate
  upstream cache-write tokens, originator sources, session_meta line
  detection, and filter_codex_usage_files date-window skipping. Bump the
  group, per-file event, and all-agent row cache discriminators.
- Claude: rewire the cached daily/session summary wrappers onto
  upstream's date-scoped loaders (ccusage#1664).
- OpenCode: keep WAL-signature cache signatures, the summary cache
  wrapper, and --no-cost -> Display mapping; take upstream's v2 session
  usage loading and split directory loader.
- Pricing: keep the explicit GLM-5.2 rates and 1,000,000-token context
  limit (now via put_builtin_entry for both GLM-5.1 and GLM-5.2); take
  upstream's DeepSeek V4 scheduled rates and catalog rules.
- Terminal: keep full dates whenever the minimum full-date layout fits
  and attached breakdown rows; take upstream's content-aware fallback
  minimums and numeric-column floors, adapting the 80-column regression
  test to the personal full-date policy.
- Presentation: keep the hidden-by-default Models column and the
  all-agent --with-models opt-in; regenerate zcode/copilot session
  snapshots under the wider first-column floor.
- Ledger: audit baseline updated to 8841f92; heuristic Antigravity and
  replay suppression recorded as retired divergences.
