From bb3f4bd62b61d51884e4032bfd432da4cec5da89 Mon Sep 17 00:00:00 2001 From: Bryan Helmkamp <19+brynary@users.noreply.github.com> Date: Mon, 25 May 2026 17:22:32 -0400 Subject: [PATCH] feat(model): add gemini-3.5-flash (#403) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Updates the built-in Gemini catalog for the current Gemini API lineup by adding `gemini-3.5-flash` and promoting `gemini-3.1-flash-lite` to the canonical small default. The old `gemini-3.1-flash-lite-preview` ID remains accepted as an alias and resolves to the stable API ID, avoiding a breaking change for existing workflows. The catalog test changes remove Gemini-specific data assertions and keep only a generic small-default invariant, so future declarative catalog updates do not require Rust test churn. ## Verification - `cargo nextest run -p fabro-model` - `cargo +nightly-2026-04-14 fmt --check --all` --- [![Compound Engineering](https://img.shields.io/badge/Compound_Engineering-6366f1)](https://github.com/EveryInc/compound-engineering-plugin) 🤖 Generated with GPT-5 (unknown context, default reasoning) via [Codex](https://openai.com/codex) --- docs/public/core-concepts/models.mdx | 3 +- lib/crates/fabro-model/src/catalog.rs | 107 +++--------------- .../src/catalog/providers/gemini.toml | 41 +++++-- 3 files changed, 53 insertions(+), 98 deletions(-) diff --git a/docs/public/core-concepts/models.mdx b/docs/public/core-concepts/models.mdx index c92d89824..71e8d6e4a 100644 --- a/docs/public/core-concepts/models.mdx +++ b/docs/public/core-concepts/models.mdx @@ -28,8 +28,9 @@ No single model is best at everything.
