Don't see your model?
Bear Lumensupports any model with token-based pricing. If your provider isn't listed, request support and we'll add it to the rate card catalog.
Request model supportHow model detection works
The Bear Lumen SDK inspects the API response to identify the provider and model automatically. Pass the raw provider response to bear.track(response) and costs are calculated using the matching rate card. For models not in the catalog, costs are tracked as zero until a rate card is added.
