Why aggregate AI APIs?
The AI model landscape changes weekly. New models launch, pricing shifts, capabilities expand. Building directly against individual provider APIs locks you into their ecosystem and makes it painful to evaluate alternatives.
An LLM API aggregator decouples your application from any single provider. Test Claude against GPT-4o by changing a parameter, not rewriting your integration. Route production traffic to the cheapest model that meets your quality bar. Fall back to alternatives when a provider has an outage.
InferAll provides this aggregation layer with zero markup on token prices for premium models. The 186 free models on NVIDIA NIM cover most development and testing needs at zero cost.
