WHY CUSTOM AI?
Custom AI will unlock your AI roadmap
Improve accuracy where it matters
Boost accuracy and reliability on your use cases to bring them to production faster
Reduce costs in production
Save up to 90% of your LLM spend
Lower latency
Up to 10x faster models
Minimize reliance on closed model providers
Run models wherever you want, on the infra you trust most, with no more silent API changes and forced model migrations
...and it just became much easier to build custom AI.
The Old Way
It used to take months to train a custom model
You needed to be an ML expert in order to create a custom model that worked
You needed to have tons of high quality data
When a new model was released, your custom model would be obsolete
The Oumi Way
Build custom models in hours with targeted automation
Oumi's intelligent flows mean any engineer can create a custom model
Oumi's synthesis is unparalleled, making it easy to curate data
Evaluate newly released models, auto-update your datasets, and train a new version in minutes
