Train the models only
you can build.
Bring your model and data. We compile the kernels, find the cheapest capable hardware across providers and operate the run, from 1 GPU to 10,000.
One training stack. Two ambitions.
Whether you are teaching a model what makes your company unique or training a new model from scratch, SF Tensor turns training into an outcome instead of an infrastructure project.
For enterprises
Turn proprietary data into proprietary advantage.
Continuously post-train models on the domain knowledge your organization already owns without handing over the data or assembling an ML infrastructure team.
For AI labs
Train frontier ideas, not infrastructure teams.
Take a novel architecture from one GPU to a frontier run across the best available hardware, with optimized kernels and resilient infrastructure built in.
Buy the training outcome.
We'll handle how it runs.
Choose the model, data, budget and deadline. SF Tensor turns fragmented compute into a reliable training system.
01. Average training savings
Cut the price of training runs by an average of 70%.
02. From research to training
From a working training repo to an optimized, managed fleet.
03. Scale, zero code changes
Use the same workflow for a single experiment or a fleet-scale training job.
Every layer between code and compute.
One system chooses the hardware, optimizes the workload, proves the generated kernels and operates the training run.
Tensor Cloud
LiveTensor Cloud automatically finds the cheapest hardware across providers, then orchestrates the job and handles placement, checkpointing and failure recovery, whether you need 1 or 10,000 GPUs.
Plan a training runKernel Optimizer
LiveOur optimizer searches workload-specific kernels, models memory and hardware topology and formally verifies the result before it reaches a production training run.

Emma Language
Emma is where our vision started: a language that abstracts away the quirks of individual platforms without giving up hand-tuned performance. Write it once, target GPUs today, TPUs tomorrow and whatever comes next.

We charge a share of the verified savings against your baseline cost. If we don’t cut your bill, you don’t pay.

Forward-Deployed
For teams looking to scale their training runs and need support and control over their infrastructure.
Your model is the advantage. Infrastructure shouldn't be the constraint.
Bring the model, data and ambition. We'll optimize the kernels, orchestrate the fleet and deliver the training outcome.
Train the models only you can build. One stack for enterprise post-training and frontier pre-training.
