You are overpaying for inference.
We fix that.

Our inference gateway serves you frontier intelligence, but at a fraction of the cost.

Relax.

Model selection is no longer your job.

Auto-tune for your inference: quality held at the right level, cost brought down automatically and continually. No pickers, no routing rules, no retry trees.

Swap in the endpoint.

Compatible with the OpenAI, Anthropic, and Gemini APIs. New base URL, new key. Nothing else changes, in any stack, framework, or harness.

We learn your traffic.

The gateway analyzes your real usage: request classes, applications, token and latency profiles.

We construct evals from real workloads.

Built around your actual use cases, not generic benchmarks. Your traffic sets the quality bar.

Every request gets the right model.

When a cheaper model proves parity on your evals, it takes over. The workload is pinned to it behind the endpoint.

The endpoint improves over time.

New models are tested against your evals as they release. Quality stays above your floor; cost per token goes down.

The inference gateway

Quality pinned.
Cost falling.

We build evals off your workloads and choose the right model at a lower cost. You start saving immediately, with receipts to prove it.

A substitution is pinned in only after parity is confirmed on your own workloads. Then the saving is permanent.

Illustrative: a representative production workload across twelve months. Each marker is a model substitution pinned in after evals confirmed parity. Live workloads on the gateway today run 75 to 90% cheaper than before the switch.

Drop-in by design

One line to switch.

Call the di-fusion model alias, or keep the model ids you already send. Both just work.

Keep your SDKs.

Native OpenAI, Anthropic, and Gemini API compatibility: streaming, tool calls, structured output.

Keep your stack.

Works with any framework, agent harness, or gateway you already run. Nothing to install, nothing to operate.

Keep your model ids.

Send di-fusion or the model IDs you already use. Substitutions happen behind the endpoint either way. You never migrate or redeploy.

from openai import OpenAI client = OpenAI(    base_url="https://api.directinference.com/di/v1",    api_key=os.environ["DI_API_KEY"],) resp = client.chat.completions.create(    model="di-fusion",  # or keep your existing ids    messages=[{"role": "user", "content": "..."}],)

That’s the whole migration. Everything else stays exactly as it is.

saved by our largest customers, every month

Handles high-throughput production workloads.

State-of-the-art performance on public benchmarks.

And then, every month

Delivering inference that gets cheaper over time.

You never watch a leaderboard or rerun a migration. The gateway retests new models against your evals, pins the winners, and lowers your cost per token on its own, month after month, while your code stays untouched.
