Compare AI models through one API
Which model is best for your use case? With InferAll, test GPT-4o, Claude Sonnet 4, Gemini 2.5, and Llama 405B side-by-side. Same API, same format — just change the model parameter.

| Model | Context | Cost | Best for |
|---|---|---|---|
| Llama 405B | 128K | Free | Development, testing, cost-sensitive production |
| Gemini 2.5 Flash | 1M+ | Low | Large documents, long context, multimodal |
| Claude Sonnet 4 | 200K | Medium | Code generation, reasoning, analysis |
| GPT-4o | 128K | Medium | General purpose, vision, function calling |
| Claude Opus | 200K | High | Complex reasoning, research, creative writing |
No integration overhead
Without InferAll, comparing models means setting up accounts with each provider, learning their SDK, managing separate API keys, and writing translation code. Testing five models requires five integrations.
With InferAll, you write one integration. Change the provider and model parameters to test any model. The request format, authentication, and response format stay the same. Compare latency, quality, and cost across providers in minutes, not days.

// Same prompt, every model — find the best one for your task
const models = [

{ provider: "gemini", model: "gemini-2.5-flash" }, // Low cost
{ provider: "anthropic", model: "claude-sonnet-4-20250514" }, // Medium
{ provider: "openai", model: "gpt-4o" }, // Medium
