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.

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.

Evaluate for your use case

// Same prompt, every model — find the best one for your task
const models = [
  { provider: "nvidia", model: "meta/llama-3.1-405b-instruct" },  // Free
  { provider: "gemini", model: "gemini-2.5-flash" },               // Low cost
  { provider: "anthropic", model: "claude-sonnet-4-20250514" },     // Medium
  { provider: "openai", model: "gpt-4o" },                         // Medium
];

for (const { provider, model } of models) {
  const start = Date.now();
  const res = await fetch("https://api.inferall.ai/ai/v1/generate", {
    method: "POST",
    headers: { Authorization: "Bearer kr_user_..." },
    body: JSON.stringify({ provider, model, messages: [
      { role: "user", content: "Write a Python function to merge two sorted arrays" }
    ]}),
  });
  const data = await res.json();
  console.log(model, Date.now() - start + "ms", data.text?.slice(0, 100));
}
