Yes, with one caveat about what “CUDA for Rust” means. Rust code can already call CUDA’s APIs from the host side through binding libraries such as cudarc. Writing the GPU kernel itself in Rust is the newer part. NVIDIA’s technical blog post of September 8, 2026 describes two native Rust kernel tracks: cuda-oxide, which uses a SIMT (single instruction, multiple threads) model, and cuTile Rust, which uses a tile-based model. cuda-oxide is labelled an early-stage alpha, and NVIDIA describes the wider effort as still maturing.
What “CUDA for Rust” covers
NVIDIA presents CUDA as a full GPU development environment: programming guides, compiler documentation, APIs, libraries, profiling tools, installation instructions and release notes. The CUDA Programming Guide defines the platform this way:

Host side: calling CUDA from Rust
If your program allocates device memory, copies data and launches work on the GPU, you need host-side bindings. cudarc provides Rust bindings to CUDA APIs for this job. The Rust-CUDA project guide also describes CUDA ecosystem libraries for Rust. Neither tells you how to write the kernel. That gap, where Rust could launch a kernel but the kernel itself was often written in another language, is what NVIDIA’s newer announcement targets.
Device side: writing the kernel in Rust
A kernel is the function that runs on the GPU. Rust-CUDA has aimed to compile Rust GPU code to PTX, NVIDIA’s virtual GPU instruction format. The cuda-oxide and cuTile Rust tracks are NVIDIA’s current routes for native kernel authoring.
The two native kernel tracks
cuda-oxide: SIMT kernels
cuda-oxide is the SIMT route. It compiles Rust kernel code to PTX through a custom backend, and you write per-thread code in Rust. The project’s book describes its v0.1.0 release as “an early-stage alpha” that may contain bugs, incomplete features and API breakage.

cuTile Rust: tile-based kernels
cuTile Rust uses a different model. Instead of reasoning about individual threads, you express the computation in terms of tiles, and the project maps that model to CUDA Tile IR. The two tracks are different programming approaches, not interchangeable wrappers, so the choice depends on how you want to describe the computation. NVIDIA says it intends to keep developing CUDA Rust into 2027 and beyond.
What the published benchmark does and does not show
The 2026 paper Fearless Concurrency on the GPU reports cuTile Rust results on an NVIDIA B200: 7 TB/s on element-wise operations and 2 PFlop/s on GEMM, which the authors report as 96% of cuBLAS. These are paper-reported measurements for those two operation types on that one device. They are not a general performance guarantee, and they say nothing about other workloads or other GPUs.
How the options compare
The options sit at different layers. The table separates host-side bindings from kernel authoring and lists the requirements each source states.

Requirements, project by project
Each project has its own prerequisites, and they do not combine into one minimum for “Rust CUDA.” Versions and GPU support change, so confirm against each project’s current setup page before installing.
Rust-CUDA
- An NVIDIA GPU with Compute Capability 5.0 (Maxwell) or later
- CUDA 12.0 or newer
- An appropriate NVIDIA driver
- LLVM 7.x
The Rust-CUDA setup page notes that the LLVM 7.x requirement can make installation difficult. It points to Docker images that include CUDA and LLVM as an alternative.
cuda-oxide (SIMT track)
- Linux
- A GPU with Compute Capability 8.0 or later (the Ampere generation and newer)
- CUDA Toolkit 12.x or newer
- clang with libclang headers
- A pinned nightly Rust toolchain
Use the nightly version the project specifies, not your default stable toolchain.
CUDA Toolkit installation
NVIDIA’s installation guide covers three Linux routes for the CUDA Toolkit: a system package manager, the runfile installer and Conda. Its pip wheels are oriented toward Python runtime use.
Version numbers also differ across NVIDIA’s own pages. The toolkit landing page highlights CUDA 13.4, while the CUDA Programming Guide it links is Release 13.2. Do not assume the two describe the same release. Match the documentation to the toolkit you actually install.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Choosing a path
- Your program only needs to call CUDA from Rust. Start with cudarc. Your kernels can stay in whatever language they already use.
- You want per-thread (SIMT) Rust kernels and your environment meets the cuda-oxide requirements above. Evaluate cuda-oxide, accepting alpha-stage APIs and pinning the nightly it specifies.
- You want to express kernels as tiles. Evaluate cuTile Rust. NVIDIA’s announcement does not list its prerequisites, so confirm them on the project’s own pages before installing anything.
- You need the widest GPU range. Rust-CUDA lists the oldest GPU baseline of the Rust options, but it depends on LLVM 7.x.
- You need the same kernel code on non-NVIDIA GPUs. CUDA is the wrong layer. Evaluate cross-vendor projects such as CubeCL separately.
For production code, check each project’s release notes, open issues and feature support, and validate the kernel on your own workload and hardware.
