What GPT-6 Sol is good for

GPT-6 Sol is the original GPT-6 Sol coding and agent tier. GPT-6.1 Sol is a distinct newer successor; Luna is cheaper, while Astra is the flagship. It accepts text and image inputs and generates text, with adjustable reasoning effort. The documented large context capacity is useful for substantial inputs, though unusually long API requests may be charged differently. Evaluate response quality against the neighboring tiers before committing a workflow, since matching context windows do not imply matching capability. Borg includes this lane in its subscription; Borg Fusion can route to it, or you can select its lane directly for a fixed model choice.

How Borg uses it

GPT-6 Sol is available as a subscription catalog lane in Borg. The catalog does not publish which Fusion profiles route to this model, so no routing role is claimed here. You can pick it directly by setting the OpenAI-compatible gateway model field to a listed lane id. Check the current catalog for availability before building a workflow around a lane.

Time to first token (gateway proxy): time until the first streamed response event reaches the gateway; our closest available measure of time to first token
Tokens per second (end to end): tokens per second, end to end: provider-reported output tokens divided by the whole turn's elapsed time, including queueing and reasoning; not a streaming per-token rate

Share of requests Borg completed successfully, excluding requests the client cancelled.

Completion speed covers the whole turn including queueing and reasoning time; it is not a streaming tokens-per-second figure.
