Pre-optimized Model APIs
Test new workloads, prototype products, or evaluate the latest AI models optimized to be the fastest in production — instantly.
Run Training on Baseten
Train your models with frontier RL using the Loops SDK and easily deploy them to production inference on the same stack.
from loops import Trainer
trainer = Trainer(model="your-model")
trainer.run() # deploy on the same stack
trainer = Trainer(model="your-model")
trainer.run() # deploy on the same stack

Customers
What our customers are saying.
“With Baseten Embeddings Inference, we immediately saw 3× speed improvements. Doctors rely on speed when treating patients, and that improvement has been critical to our product experience. 160 millisecond latency is crazy.”
Jagath Jai Kumar
Full Stack Engineer, OpenEvidence
“I want the best possible experience for our users, but also for our company. Baseten has hands down provided both. We really appreciate the level of commitment and support from your entire team.”
Nathan Sobo
Co-Founder, Zed Industries
“With Baseten, we gained a lot of control over our entire inference pipeline and worked with Baseten's team to optimize each step.”
Sahaj Garg
Co-Founder and CTO, Wispr
“With the launch of Brain MAX we've discovered how addictive speech-to-text is — we use it every day and want it everywhere. Baseten helped us unlock sub-300ms transcription with no unpredictable latency spikes. It's been a game-changer for us and our users.”
Mahendan Karunakaran
Head of Mobile Engineering, ClickUp
“Inference for custom-built LLMs could be a major headache. Thanks to Baseten, we're getting cost-effective high-performance model serving without any extra burden on our internal engineering teams. Instead, we get to focus our expertise on creating the best possible domain-specific LLMs for our customers.”
