The model metadata database shipped with SynapseBridge — a WinUI 3 desktop AI workbench from Gain Publications.
models_db.json is a JSON array (currently 936 entries) describing the LLM models SynapseBridge knows about: capabilities, context windows, max output tokens, vision support, tool support, pricing hints, and a stable canonical name per model.
This repo is NOT a user-facing override mechanism. Starting with SynapseBridge v1.0, the program does not automatically pull from this repo on launch. Major catalog updates ship through Microsoft Store program updates instead.
If you're a SynapseBridge user looking to manually update your local model database:
- Manual replacement is not recommended — your changes will be overwritten by the next program update.
- You can drop a JSON file at
%LOCALAPPDATA%\Packages\GainPublishing.SynapseBridge_<hash>\LocalCache\Roaming\SynapseBridge\models_db.jsonif you really want to override locally, but it's at your own risk. - The shipped MSIX includes the canonical bundled copy under
Assets\models_db.json— that's the source of truth for any given SynapseBridge version.
- Source-of-truth tracking for the bundled JSON across releases
- A reference for anyone building tooling that consumes the same model metadata
- A historical record of how the catalog has evolved
This isn't an open-contribution repo right now. The bundled JSON ships with SynapseBridge and is curated alongside program releases. If you spot an error or want a model added, open an issue and it'll be considered for the next release.
See LICENSE for terms. The JSON itself is metadata about third-party models; SynapseBridge and Gain Publications make no warranty about its accuracy.
