HoprLab is a CLI and research toolkit for simulating AI training math before spending time and money on model training.

The working MVP lives in [ hoprlab/](/TangibleResearch/HoprLabs/blob/main/hoprlab). It estimates model size, activation memory, optimizer memory, approximate VRAM usage, training time, token budget, config risks, benchmark speed, and reliability.

```
cd hoprlab
python3 -m venv .venv
.venv/bin/pip install -e ".[dev]"
.venv/bin/hoprlab estimate configs/example_transformer.yaml
.venv/bin/hoprlab simulate configs/example_transformer.yaml
.venv/bin/hoprlab benchmark
.venv/bin/hoprlab test-reliability configs/example_transformer.yaml
```

Or use the root Makefile:

```
make setup
make test
make build
make reliability
```

HoprLab includes optional native benchmark modules:

- Rust:
`hoprlab/native/rust`

- C:
`hoprlab/native/c`

The Python CLI falls back gracefully when native backends are unavailable.
