- Cost-sensitive teams
How GPT-OSS 120B works inside Kryotta
Pick GPT-OSS 120B in the model picker and chat as usual — or leave the picker on Auto and Kryotta routes each prompt to the model that does the job best for the least cost, GPT-OSS 120B included. Every answer shows which model produced it. Add it to a Compare run to see it against Claude 3.5 Sonnet and Claude 3 Haiku on the exact same prompt. Usage from every model counts against one pooled allowance, so your team gets one predictable bill.
