Yes. Tenstorrent says Blackhole is "supported by Tenstorrent's fully open source software stack, granting developers full access to the metal."
The stack
Tenstorrent's documentation lists four main components:
| Component | What it is |
|---|---|
| TT-Forge | End-to-end MLIR compiler for models from PyTorch, JAX and ONNX |
| TT-NN | High-level Python API of pre-optimized neural-network operations |
| TT-Metalium | Low-level C++ SDK for writing custom kernels on Tensix cores |
| TT-MLIR | MLIR-based compiler infrastructure that lowers models onto Tenstorrent hardware |
The docs link to a GitHub organization holding the public source repositories for the software stack, compilers, tools and demos, including tt-metal.
The hardware side
Tenstorrent's Blackhole page lists 120 Tensix cores, 16 big RISC-V cores and up to 32GB of GDDR6 per chip. See Tenstorrent Blackhole vs NVIDIA for the comparison, whether Tenstorrent supports PyTorch, and NVIDIA's main competitors in AI.
