Learn why teams choose AssemblyAI’s managed LLM Gateway over standing up and running LiteLLM themselves:
No proxy to deploy, no database or Redis to run, no upgrades to schedule. Call one hosted endpoint and ship—the infrastructure is ours to operate.
Pay provider token rates with no gateway markup and no minimum commitment. The price you see is the price you pay.
Configure a primary model and any number of backups per request. If a provider errors or rate-limits, the Gateway retries the next model—no code changes.
Transcribe with AssemblyAI’s own speech models and apply any LLM to the result in one pipeline—no second vendor and no extra network hop.
GPT, Claude, Gemini, Qwen, Mistral, and more behind one OpenAI-compatible API. New models are added the day they launch.
Drop into any OpenAI SDK or HTTP client. Change a base URL and a model string, and the rest of your code keeps working.
EU-resident infrastructure on by default for EU traffic, plus opt-in zero data retention per request—managed for you, not left to your ops team.
Sign a Business Associate Addendum for applications that process PHI, backed by SOC 2 Type 2, ISO 27001, PCI DSS, and GDPR.
Get your free API key and make your first Gateway call in minutes—no infrastructure to stand up.
The same transcript, four different jobs, four different models — all routed through one endpoint.
What is runner's knee?
Based on the transcript, runner's knee is a condition characterized by pain behind or around the kneecap. It is caused by overuse, muscle imbalance and inadequate stretching. Symptoms include pain under or around the kneecap and pain when walking.
Summarize this call in three bullet points
• Caller reports persistent knee pain after long runs. • Clinician identifies likely runner's knee from overuse and weak hip stabilizers. • Recommended next steps: rest, ice, targeted glute and quad strengthening.

Hi — thanks for coming in today. As we discussed, your knee pain is consistent with patellofemoral pain syndrome (runner's knee), and I'd recommend two weeks of reduced mileage along with the strengthening routine I sent over.
