Improve ML models 100x faster

SigOpt’s API tunes your model’s parameters through state-of-the-art Bayesian optimization.

  • Exponentially faster and more accurate than grid search. Faster, more stable, and easier to use than open source solutions.
  • Extracts additional revenue and performance left on the table by conventional tuning.

What is SigOpt?

SigOpt automates the tuning of your model’s hyper, feature, and architecture parameters. If you’re not optimizing them, you’re forsaking significant performance and revenue gains.

Modelers often overlook these optimizations because traditional approaches like manual, grid, and random search are time-consuming and produce subpar results.

Let SigOpt modernize your workflow so you can focus on what you’re best at: designing your model and understanding your data.

“SigOpt optimized our fund’s financial models 15 times faster than grid search. Our models now perform better, and our engineers are free to focus on model design instead of tuning.”

– Max Logunov, PhD, Developer @ Optimus Investments

How SigOpt Works

1  Provide parameters

Ping our API with your model’s parameters. We don’t need the model itself. You keep it private.

2 Use our values

Our API suggests new values for these parameters. Use them to evaluate your model within your current infrastructure.

3 Send model output

We use your model’s output to calculate the next best configuration.

4 Repeat until optimized

You’ll reach optimal values up to 100x faster than other methods.

Works with every model
Integrates with every platform

Faster Than Everything Else

The world’s most efficient Bayesian optimization

We outperform traditional and alternative Bayesian techniques on a collection of benchmarks and real-world problems. We also outperform MOE, spearmint, SMAC, and hyperopt in a wide variety of problems.

Those tools usually represent a single optimization approach and are often too brittle for production. SigOpt is an ensemble of state-of-the-art, proprietary optimization strategies.

It’s why Huawei, Prudential, and MIT rely on us.
