Learn why teams building Voice AI choose AssemblyAI’s managed LLM Gateway over running Kong’s gateway themselves:
No Nginx data planes, vector databases, or plugin tiers to run. Call one hosted endpoint—the routing and reliability infrastructure is ours to operate.
Call 25+ frontier models through one API at provider rates. Kong hosts no models, so you still contract with and pay each provider yourself.
Transcribe with AssemblyAI’s own speech models and apply any LLM to the result in one pipeline. Kong is a routing layer with no first-party speech at all.
Pay provider token rates with no gateway markup and no minimum commitment—not enterprise-only reliability features on custom, unpublished pricing.
Configure a primary model and any number of backups per request—included, not gated behind an enterprise tier. If a provider fails, the Gateway retries the next model.
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 a self-hosted configuration exercise.
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.
