Key Features

Parallelized Pharmacometric Model Runs

Run multiple pharmacometric models simultaneously across GPU compute units, dramatically reducing total execution time.

GPU-Assisted Numerical Optimization

Harness GPU parallel processing to accelerate the numerical optimization routines that are at the core of parameter estimation.

Faster Model Convergence

Optimized algorithms and GPU compute allow models to reach convergence in a fraction of the time compared to traditional CPU workflows.

Large-Scale Simulation Capabilities

Run thousands of virtual subject simulations in parallel for clinical trial simulation and model evaluation.

See it in action

Historical recording — July 2026. The interface, results, and capabilities shown are not a statement of current live validation.

Load a real control stream and dataset, press Run fit, and PharmFast estimates the model on the GPU in seconds — reproducing NONMEM 7.6 to the last digit. Here, the classic Theophylline model converges in ~3 s with ΔOFV = 0.0001 versus the NONMEM reference.

23 runnable worked examples — every ADVAN, method, and error model.

Converged on GPU with a live NONMEM parity check (ΔOFV = 0.0001).

Parameter estimates with SE / %RSE from the diagnostics run.

Built for Complex Modeling Challenges

Whether you are running population PK/PD models, PBPK simulations, or large-scale clinical trial simulations, PharmFast eliminates the computational bottleneck that slows down iterative model development cycles.
