Intel Ships NPU Driver 1.35.0 with Wildcat Lake Support and Generative AI Optimizations
The stable release lands just two days after the RC, bringing firmware updates, dynamic shape hints, and a cleaned-up build system to Linux AI PCs.
Intel has released NPU Driver 1.35.0. It's stable now. The commit fd49947d hit the tag on July 24, 2026. The same code shipped as RC1 on July 22. That means Intel's quality assurance team found no regressions in two days. That's unusually fast for a driver touching firmware, kernel, and compiler.
Wildcat Lake is the headline here. This is the value chip. It drops the "Core Ultra" branding for "Core Series 3". The NPU gets 15-17 TOPS. Not the 50 TOPS of the flagship Panther Lake, but plenty for budget AI PCs. I remember when the first public release of this driver landed back in October 2025. Back then, you needed a compiler hat to build it. Now? You can dpkg -i *.deb and you're good. The bar has moved.
Verified Config and Wildcat Lake
Wildcat Lake is now in the Verified Configuration table. Ubuntu 24.04 LTS with kernel 6.17.0-40-generic. You'll need the vpu_50xx firmware binary. It's the same one used for Panther Lake. The header file added 45 new lines. These include VpuPtr for safe cross-address-space pointers. You'll want that when writing multi-threaded inference code.
Dynamic shapes. The driver now has optimizeForDynamicShapes. This helps with LLM token generation where context lengths vary. You'll likely see this matter most when running local Llama models via OpenVINO.
Level Zero is now v1.28.2. Tracing now includes thread IDs. Multi-threaded debugging just got easier.
Compiler modernization. New API function vclAllocatedExecutableCreate4(). Old API is deprecated. You should switch over.
Build system. Perfetto SDK inlined. 286,000 lines. No more submodule headaches for air-gapped builds.
Firmware. Five families. 50xx for Panther/Wildcat. Header changes for scheduling barriers.
It's a solid update. The jump from v1.33.0 to v1.35.0 happened in under eight weeks. That pace tells you Intel is serious about keeping this stack current. However, at the same time, WSL2 support is still listed as "open" in the issue tracker. If you're running Linux in a VM on Windows, keep waiting.
If you need more details, the full diff between v1.33.0 and v1.35.0 spans roughly 289,700 line changes. It's arguably the most mature open-source NPU driver stack on Linux right now. Six months later, the gap between this and competing offerings hasn't narrowed. Intel's pushing hard.
