Catalog overview

The catalog is Syntax's curated set of models. It includes hundreds of open-weight and provider-hosted models across every model purpose Syntax supports — text generation, embedding, image generation, video generation, OCR, segmentation, TTS, audio generation, mesh recovery, UI grounding, audio transcription, speech-to-speech, image processing, video processing, reranking, and time-series forecasting.

What's in the catalog

Each catalog entry includes everything Syntax needs to serve the model without you having to wire it up by hand:

• The model's identity (name and provenance).
• Its model purpose (e.g., text generation, image generation, OCR).
• Its modalities (text, image, video, audio).
• Recommended serving parameters for the engines Syntax can use.
• The model's license, so attribution and usage requirements are surfaced before you deploy.

When a model is in the catalog, deploying it is a one-click operation on any supported target — local, self-managed remote, managed remote, or routed to a hosted provider.

Open-weight vs provider-hosted

The catalog mixes two kinds of models:

• Open-weight models that Syntax can serve directly on your local hardware, on a self-hosted remote, or on managed remote (dUX). The weights are downloaded and served by Syntax.
• Provider-hosted models that Syntax routes to (OpenAI, Anthropic, Google, etc.). You bring the API key; Syntax handles the routing, alias resolution, and budget tracking.

A single model can have both faces — for example, a frontier model reachable through a hosted provider and an open-weight equivalent you can run locally — and Syntax routes per session based on your preferences.

How to browse

The desktop app's Catalog page is the primary surface for browsing models. It supports:

• Search by name or capability.
• Filter by model purpose, modality, size, license, and curated tier.
• Sort by recency, parameter count, or curated rank.

The Catalog page is read-only — you browse here, then move to the Deployments page (or the Party Builder) when you're ready to deploy.

Per-model deployment options

Every catalog entry exposes:

• Download Locally when local serving is supported on your hardware.
• Download Remotely when you have a self-managed remote target configured.
• Serverless activation when the model is reachable through a hosted provider you've configured.

Whether a button is enabled depends on your hardware tier and your configured providers — Syntax greys out options that won't work rather than letting you pick something that will fail.
