# CommitBrief v1.4.1

> A model-refresh release — OpenAI GPT-5 family support (including gpt-5.5-pro via the Responses API), the Gemini 3.x lineup, Claude Opus 4.8 as the new Anthropic default, and a setup wizard that no longer makes you retype an API key just to switch provider or model.

Released May 30, 2026

## Added

- **OpenAI GPT-5 family — `gpt-5.5`, `gpt-5.4-mini`, `gpt-5.5-pro`.** All three
  are selectable in `commitbrief setup` with correct context windows
  (1.05M / 400K / 1.05M input) and pricing. The new default OpenAI model is
  **`gpt-5.4-mini`**. `gpt-5.5-pro` runs through OpenAI's Responses API (it
  isn't offered on Chat Completions) and can take several minutes per review;
  reasoning models get a larger default output-token budget so a findings
  response is never truncated by reasoning tokens.

- **Gemini `gemini-3.5-flash`.** Added alongside the rest of the refreshed
  Gemini lineup below.

## Changed

- **Gemini lineup refreshed to the 3.x family.** `gemini-2.5-pro` →
  `gemini-3.1-pro-preview`, `gemini-2.5-flash` → `gemini-3.5-flash`,
  `gemini-1.5-flash` → `gemini-3.1-flash-lite`. The new default Gemini model
  is **`gemini-3.5-flash`**. Pricing and context windows updated;
  `gemini-3.1-pro-preview` carries tiered pricing (the ≤200K-token base tier
  is snapshotted). Configs pinning a removed 2.x / 1.5 model should switch to
  a 3.x ID.

- **Anthropic: `claude-opus-4-7` → `claude-opus-4-8`.** Opus 4.8 is now the
  default Anthropic model, with its built-in pricing ($5 input / $25 output /
  $0.50 cache-read per 1M) and 1M-token context window updated to match
  Anthropic's current model docs. Configs pinning `claude-opus-4-7` should
  switch to `claude-opus-4-8`.

- **`setup` no longer forces an API-key re-entry when one already exists.**
  Re-running `commitbrief setup` for a provider that already has a key now
  lets you leave the key prompt blank to keep the stored key, so switching
  only the active provider or model doesn't mean retyping credentials.
  First-time configuration still requires a non-empty key. For a
  non-interactive path, `providers use <name>` switches the active provider
  and `config set providers.<name>.model <model>` changes the model — both
  leave API keys untouched.
