It uses Messages with adaptive thinking, drops sampling options, + forwards forced tool choice, and has a 1,000,000-token context and + 128,000-token output limit. Prompts over 100,000 tokens, counting cache reads + and writes, are priced at $0.50/$0.05/$0.625/$2.50 per million input, cache + read, cache write and output tokens instead of $0.10/$0.01/$0.125/$0.50, and + one-hour cache writes at $1 instead of $0.20. Live text and tool cases + passed on 2026-10-10, and a live request confirmed forced tool choice with + adaptive thinking. + +### Changed (breaking) + +- `Baikai.Model.InputPriceTier` gains a third field, `longCacheWriteCost :: + Maybe Rational`: the one-hour cache-write rate for requests that cross that + tier. `resolveRates` now takes the long rate from the selected tier rather + than overriding every tier with the policy-level rate, and validation rejects + a policy whose policy-level long rate leaves any tier without one. Tier JSON + without the key decodes as `Nothing`. __Breaking__: positional constructions + of `InputPriceTier` need the new argument. + ### Changed +- Catalog: the 2026-10-10 model refresh lowers `anthropic_claude_sonnet_5_5`'s + cache-read rate from $0.20 to $0.10 per million tokens, following Anthropic's + 2026-10-07 price cut, and corrects `anthropic_claude_sonnet_4_5`'s context + window from 1,000,000 to 200,000 tokens (its 1M beta ended on 2026-04-30). + Claude Haiku 5.5 was curated separately (see Added). No OpenAI model was + added. + - Documentation: the 2026-10-02 model refresh found no new OpenAI or Anthropic models; the catalog is unchanged. `docs/user/models-and-providers.md` notes Anthropic's retirement of Claude Sonnet 4.5 on 2026-11-30 (deprecation of - `anthropic_claude_sonnet_4_5` is planned in plan 89 for removal in 0.8.0.0), + `anthropic_claude_sonnet_4_5` is planned in plan 89 for a future release; + it remains in 0.8.0.0), why the access-gated Claude Mythos models are not curated, and how GPT-6 Astra's new ultrafast service tier is costed. + +### Fixed + +- The shared batch subprocess scope now owns POSIX process groups, joins pipe + readers, and synchronously reaps direct children before acknowledging + cancellation. Executable-version probes use the same scope. Darwin/Linux + coverage excludes processes that deliberately escape the group and adopted + descendant reaping; Windows retains direct-child cleanup. The provider fixes + ship in `baikai-claude 0.7.1.1` and `baikai-openai 0.7.1.1`; see + [plan 90](docs/plans/90-terminate-owned-batch-cli-process-groups-before-acknowledging-cancellation.md) + and [BUG-1](docs/bug-reports/batch-cli-cancellation-leaves-child-alive.md). + +- `baikai`'s source distribution now ships `data/models/*.json` and the test + suite's fixtures under `test/fixtures/`. Without them, running the suite from + the Hackage tarball failed 27 of 794 tests on missing files: the fixtures + themselves, plus the catalog round-trip test, whose `baikai-gen-models` run + had no model data to read. + +## [baikai-claude 0.7.1.1] - 2026-10-10 + +### Fixed + +- Batch `claude -p` calls stop owned POSIX process-group members and join pipe + readers before acknowledging cancellation, including active synthetic streams + and evidence probes. Preserves the original asynchronous exception. Resolves + [BUG-1](docs/bug-reports/batch-cli-cancellation-leaves-child-alive.md). + +### Changed + +- Requires `baikai ^>=0.8.0` for shared subprocess ownership and the new pricing + tier field. No provider API change. Haiku 5.5 request contracts are covered + by offline tests. + +## [baikai-openai 0.7.1.1] - 2026-10-10 + +### Fixed + +- Batch `codex exec` calls stop owned POSIX process-group members and join pipe + readers before acknowledging cancellation, including active synthetic streams, + repeated cancellation, and evidence probes. The temporary schema survives + until subprocess cleanup finishes. Resolves + [BUG-1](docs/bug-reports/batch-cli-cancellation-leaves-child-alive.md). + +### Changed + +- Requires `baikai ^>=0.8.0` for shared subprocess ownership and the new pricing + tier field.
