Habitat H5 · 5 sightings
Rust in AI: runtimes, kernels, and the crates behind them. Every sighting here, newest first, with its specimen number and wildness rating.
Tracel tagged Burn v0.22.0-pre.4 and CubeCL v0.11.0-pre.4 on the same day (2026-09-22). Pre-release only—not stable 0.22 / 0.11. LAMB, einsum, AMDGPU and CUDA-LLVM backends; dual MIT/Apache.
HF tagged tokenizers v1.0.0-rc.2 (2026-09-21): same API and token IDs as v0.23, performance refactor. Install with cargo add --pre. Encode 3–30× and related figures are HF/tokbench (M4 Max), not desk-measured.
smartcomputer-ai/lightspeed describes a deterministic Rust agent harness on Temporal for durable managed-agent workflows, with Postgres/optional S3 and a TypeScript/React UI. Early public repo—README claims only; Apache-2.0.
A dated brief on NVIDIA’s Sep 2026 CUDA Rust post: two early-stage kernel tracks — cuda-oxide (SIMT, early alpha) and cutile-rs (Tile) — neither production-ready. Correctness demo only; no perf claims.
A dated changelog brief on Eric Buehler’s mistral.rs v0.9.3 (tagged 2026-09-07): FP8 and DFlash decode, NVFP4 with cuTile Blackwell, and stronger Anthropic Messages / Claude Code server support. Not affiliated with Mistral AI.
