Deployment Targets:server
What It Does
- +JAX-accelerated No-U-Turn Sampler (NUTS) and HMC with automatic JIT compilation
- +Parallel chain execution across multi-GPU and TPU clusters using jax.pmap and vmap
- +Variational inference (SVI) with custom auto-guides
- +Seamless export of posterior traces to ArviZ for diagnostic analysis
What It Does Not Do
- -Natively compile to native iOS/Android mobile binaries
- -Serve REST endpoints without FastAPI or Triton wrappers
- -Process unstructured video streams directly
>Suitable Work Types
- Scaling MCMC sampling to millions of observations on NVIDIA GPU clusters
- Spatial-temporal epidemiological outbreak modeling with high parameter counts
- Bayesian neural networks combining uncertainty estimation with deep representations
>Unsuitable Work Types
- CPU-only nodes with small tabular datasets where PyMC or Stan setup is simpler
- Low-memory edge IoT microcontrollers
Data Residency Implications
Runs entirely in local GPU/TPU memory. Zero external calls.

Operational Profile & Known Limitations
Maturity:mature
Learning Curve:high
Ops Complexity:moderate
Cost Tier:free-oss
> Known Limitations:
- JAX JIT compilation on complex models can take several minutes before the first sampling step executes.
