OpenRouter vs Together AI
Compare a multi-provider LLM router with an inference platform by model access, routing control, deployment options, and token meters.
Decision rule
Choose OpenRouter when a single routing interface and provider choice are the priority. Choose Together AI when its hosted catalog, fine-tuning, or dedicated infrastructure better matches the workload. Compare the same model and token meters.

|---|---|---|
| Product | Multi-provider routing layer | Inference and fine-tuning platform |
| Route control | Provider routing and fallback options | Serverless or dedicated provider execution |
| Billing | Model and route token meters | Model tokens or dedicated endpoint capacity |
| Best evidence | Chosen route, provider, and token fields | Model SKU, endpoint type, and utilization |

Questions developers ask
Does APIDir declare a winner between OpenRouter and Together AI?
No. The decision depends on an exact model configuration, workload, reliability test, support needs, data terms, and migration risk.
Are headline prices directly comparable?

What should I verify before choosing either provider?
Open both first-party sources, reproduce the intended configuration, and measure successful output cost including errors and retries.
