Why Move Off DeepInfra?
DeepInfra is competitive on price for hosted open-source models. The trade-offs: no closed-source frontier models, and a smaller image / audio catalog than Railwail.

Why Railwail Over DeepInfra
- Same OpenAI-compatible API
- Adds closed-source models (Claude, GPT-4o, Gemini)
- Built-in playground at railwail.com/models
- Per-key rate limits and spend caps
FAQ
What about DeepInfra's deploy-your-own-model feature?
Custom model deployments are not supported on Railwail. Keep them on DeepInfra and use Railwail for the standard catalog.
Does the embedding API work the same?
Yes. POST /api/v1/embeddings accepts identical request shapes for OpenAI embedding models.
Are streaming responses supported?
Yes. Standard OpenAI SSE stream chunks.
