Frontier-level intelligence
at a fraction of the cost
Custom models compress the exact capabilities your tasks require, cutting latency and cost while improving reliability and accuracy.
Up to 95% cheaper than frontier models
Specialized models delivers high accuracy results at substantially lower cost by removing model parameters to focus only on what your workflow requires.
2-3x faster than frontier models
Custom models cut end-to-end latency by more than 50% to serve the most demanding use cases. Tune inference serving with batching, caching, parallelism, and optional speculative decoding for near real-time replies.
Immediate Impact
Our customers are already saving millions and delivering delightful low latency experiences to their users.
6 weeks from
zero to production
We work hand-in-hand with your engineering team to train, host, and optimize your custom model.
01
Training done for you
Our research team handles everything from model design, evaluations, data curation, GPU procurement, and training from beginning to end to ensure your custom model outperforms your current provider.
02
Inference at Scale
Our proprietary inference infrastructure is optimized to serve production workloads at global scale, tuned to your needs and flexible to match your exact SLAs. Scale from millions to billions of requests without interruption.
03
World-class Support
Around the clock performance monitoring, 24/7 access to our team via email, phone, and a dedicated Slack channel. We offer hands-on support from prototype to production with guaranteed one-hour response time.
Eliminate platform risk
Large labs often quantize or quietly retrain the models they're serving, resulting in unpredictable model performance. Owning your model means reliable performance without platform risk.
No model swaps
No hidden quantization
No vendor lock-in
SOC2 compliant
What our customers are saying
Thanks to Inference, we saving millions on our product inference! Their white-glove training and dedicated, highly optimized hosting made all the difference in our operations. Highly recommend!
Jake Mayor
Viral Cooking App
We had a gigantic backlog of data we needed to process. The quoted cost of running the job was in the millions of dollars. The model inference built for us saved us 95%.
Jake Mayor
Viral Cooking App
My game requires lightning fast inference. Frontier models were great for accuracy but way too slow for our purposes. The model inference trained for us is lightning fast. Its perfect.
