Build your product with pre-optimized frontier models
OneInfer Model APIs are built for production first, with the performance and reliability that only our inference stack can enable.
Ship faster
Use our Model APIs as drop-in replacements for closed models with comprehensive observability, logging, and budgeting built in.
Scale further
Run leading open-source models on our optimized infra with the fastest runtime available, all on the latest-generation GPUs.
Spend less
Spend 5-10x less than closed alternatives with our optimized multi-cloud infrastructure and efficient frontier open models.
Fast inference that scales with you
Try out new models, integrate them into your product, and launch to the top of Hacker News and Product Hunt—all in a single day.
OpenAI compatible
Swap a URL and migrate from closed to open-source models effortlessly. We fully support OpenAI structuring, function calling, and more.
Pre-optimized performance
We ship leading models optimized from the bottom up with the OneInfer Inference Stack, making every Model API ultra-fast out of the box.
Seamless scaling
Go from Model API to dedicated deployments on the hardware of your choosing in just two clicks via the OneInfer UI.
Four nines of uptime
We achieve reliability that only active-active redundancy can provide with our cloud-agnostic, multi-cluster autoscaling.
Secure and compliant
We take extensive security measures, never store inference inputs or outputs, and are SOC 2 Type II certified and HIPAA compliant.
Featureful inference
Structured outputs and tool use are baked into our Model APIs as a core part of the OneInfer Inference Stack experience.
