How do I call Leanstral 1.5 through DVARA?​

Configure the mistral provider in the DVARA LLM Gateway and send the model id labs-leanstral-1-5-1. DVARA, the AI governance platform, applies your policies, audit and cost attribution to the call. See LLM cost attribution and budgets.

In DVARA, if you haven't set your own price for a model, its calls are costed at the price in the catalogue that ships with your DVARA version. A price you set in Flightdeck always wins. You can switch catalogue prices off. Then a model with no price you set is counted as costing nothing. Every cost record says which price it used.

What should I check before relying on this data?​
