These are the OpenAI 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.

Borg Fusion can route between models in the subscription catalog according to the task and the selected profile. Having a OpenAI lane in the catalog does not mean that every Fusion profile will choose it for every request. No specific routing assignments for OpenAI are published in this catalog. 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.
The table and model details above list the current live OpenAI models in Borg. Each linked page includes the model's lane ids and available specifications. Models awaiting identity review are not shown as live.
Fusion profiles select from available lanes depending on the task. Consult each OpenAI model page for its published Fusion roles; a missing role is not evidence that the model cannot be selected directly.
Yes. Open a OpenAI 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.
