About us
About Run BiOS
Run BiOS is an AI inference and fine-tuning platform operated by Run BIOS Inc., a technology company based in San Francisco, California. The name refers to our inference layer — a basic input/output system for AI workloads — not to computer firmware.
What we do
We make it simple for companies to run AI in production — and affordable to keep it running.
One API, every model
The best open and frontier models behind a single OpenAI-compatible API. Switch models by changing one line — your code never has to know the difference.
Routing that thinks per request
BiOS Adaptive reads each request and sends it to the model that answers it best at the lowest cost. You describe the task; the platform picks the model.
Fine-tuning you actually own
Train a model on your data, on dedicated GPUs, billed per second of compute — and walk away with the weights. Your model stays yours.
The technology behind it
Most of what makes AI expensive happens at inference — the moment a model actually answers. Training happens once; answering happens millions of times a day. That is where the cost, the speed, and the user experience of every AI product live.
Our engineering goes down to the kernels — the small programs inside the GPU that do the actual math. We have modified and tuned these kernels so the same model produces better outputs and carries far more traffic at once. No new hardware, no change in answer quality — the same model, served faster and cheaper.
Fine-tuning follows the same philosophy. Bring your data, train on dedicated GPUs, and own the result — the weights, not just an API to them.
Where inference is headed
Models are getting better and cheaper every quarter, and the gap between them keeps shrinking. What separates AI products is no longer which model they picked — it is how well that model is served: how fast it answers, what each answer costs, and whether it holds up when real customers arrive.
That is the layer we are building. Inference is where AI stops being a demo and becomes a business — and the companies that win the next decade are the ones whose AI answers instantly and affordably, at any scale. We intend to be the platform they run on.
Frequently asked
What is Run BiOS?
Run BiOS is an AI inference and fine-tuning platform. It serves frontier AI models behind one OpenAI-compatible API, routes each request to the right model automatically, and fine-tunes custom models on dedicated GPUs whose output the customer owns.
Who owns Run BiOS?
Run BiOS is operated by Run BIOS Inc., a technology company based in San Francisco, California. The company runs the public site at runbios.ai and the product platform at platform.runbios.ai.
Is Run BiOS related to computer BIOS?
No. Run BiOS is an AI company and has no connection to BIOS computer firmware. The name refers to the company’s inference layer — a basic input/output system for AI workloads — not to the firmware found in computers.
How is Run BiOS priced?
Inference is priced per million tokens at published rates, and fine-tuning is billed per second of GPU time. Both are self-serve, and a public calculator estimates any workload before anything is spent.
