Borg brings multiple model providers into one subscription. Its Fusion routing profiles select an underlying model for each step, while Atlas Max provides a high-capacity lane.
These are the Borg models currently listed as live in the Borg directory. The descriptions below summarize each model's published use cases; the linked model pages give the full account. A lane id is the value you use to select a model directly in the Borg gateway, not a separate model name. Check the linked pages for context windows, reasoning support and any vendor API list prices before choosing a lane for your work.

How Fusion uses Borg
Borg Fusion can route between models in the subscription catalog according to the task and the selected profile. Having a Borg lane in the catalog does not mean that every Fusion profile will choose it for every request. Published roles for these Borg models include general, coding, design, fast. The model pages distinguish published routing roles from use cases, so you can compare options without assuming a benchmark result or a routing guarantee. You can also choose a listed lane directly if you want to control which model handles a request.
FAQ
Which Borg models are in Borg?
The table and model details above list the current live Borg models in Borg. Each linked page includes the model's lane ids and available specifications. Models awaiting identity review are not shown as live.
How does Fusion use Borg?
Fusion profiles select from available lanes depending on the task. Consult each Borg model page for its published Fusion roles; a missing role is not evidence that the model cannot be selected directly.
Can I select a Borg lane directly?
Yes. Open a Borg model page to find its Borg lane ids and the compatible gateway model field. Use the lane id rather than the public page slug when choosing a model directly.
