Models

These are the lanes in the catalogue. The numbers below are read from the same file that writes them to the database, so this page cannot drift away from what the platform actually serves.

Which lanes can be called

A lane can only be called once a rate is published for it, and not every lane in this catalogue has one — a call to a lane without a rate is refused rather than run. The gateway is the authority on which is which: every entry it serves at api.synavion.in/v1/models says whether that lane is callable, and gives its rate when it has one.

There is no comparison here to anybody else's rate. The only competitor figure we have on file is a promotional one, and a promotional rate is not a fair thing to measure ourselves against.

Callable only once a rate is published for it. GET /v1/models says which lanes have one today, needs no key, and is the only authority on it.

A capability is listed only where a test has exercised it on that lane. An unlisted capability means we have not verified it, not necessarily that the model lacks it.

All lanes run in one region: in-delhi.

Every lane is BETA

BETA here means exactly one thing: no lane has passed a capacity or reliability gate. Availability is not guaranteed, and a lane can be restarted or withdrawn without notice.

About the web lane

The web lane runs the same model weights as the plain DeepSeek lane. What differs is a retrieval stage in front of it: the lane fetches web content and puts it into the prompt before the model sees it.

That makes it a different product with different economics, not a different model. The retrieved content is billable input — measured at 374 to 521 extra tokens across three test prompts — so it is listed as its own lane with its own slug.

The two lanes are told apart by which lane you address, and by nothing else. The upstream reports the identical model name for both, which is exactly why the catalogue never keys on that name.
