From 9768651b523c748ae9c716bc64348e69f4eef947 Mon Sep 17 00:00:00 2001 From: Bryan Helmkamp <19+brynary@users.noreply.github.com> Date: Sat, 16 May 2026 05:18:21 -0700 Subject: [PATCH] feat(model): add opt-in Ollama catalog provider (#268) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Adds Ollama as a disabled-by-default built-in catalog provider backed entirely by provider TOML. Enabling `[llm.providers.ollama] enabled = true` exposes the bundled `qwen3-coder` sample model through the existing OpenAI-compatible adapter, while other local Ollama models still require explicit model blocks until fabro-sh/fabro#267 adds discovery. The docs now show the opt-in setting and note that local users can set `OLLAMA_API_KEY=ollama` for Ollama's OpenAI-compatible endpoint. ## Verification - `cargo nextest run -p fabro-model` - `cargo nextest run -p fabro-cli cmd::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 via [Codex](https://openai.com/codex) --------- Co-authored-by: roALAB1 <233429779+roALAB1@users.noreply.github.com> Co-authored-by: Claude Opus 4.7 (1M context) --- docs/public/core-concepts/models.mdx | 11 +++++++ lib/crates/fabro-cli/tests/it/cmd/model.rs | 8 ++--- lib/crates/fabro-client/src/client.rs | 11 ++----- lib/crates/fabro-model/src/catalog.rs | 29 +++++++++++++++++++ .../src/catalog/providers/ollama.toml | 26 +++++++++++++++++ 5 files changed, 73 insertions(+), 12 deletions(-) create mode 100644 lib/crates/fabro-model/src/catalog/providers/ollama.toml diff --git a/docs/public/core-concepts/models.mdx b/docs/public/core-concepts/models.mdx index 71b469545..1b52c0d58 100644 --- a/docs/public/core-concepts/models.mdx +++ b/docs/public/core-concepts/models.mdx @@ -98,6 +98,17 @@ Header values and credentials are typed references, not raw secrets.
