Bump nixpkgs and nixpkgs-latest from 2026-05/2026-08 to current
nixos-unstable (2026-09-11); both inputs now resolve to the same rev.
Re-validated every package against the new inputs.
Fallout fixed:
- freetoken: upstream pins torch>=2.11,<2.12 and triton==3.6.0, but the new
nixpkgs only ships torch 2.13 / triton 3.7. Add a nixpkgs-torch211 input
pinned at the previous revision and build freetoken against it, keeping
the CUDA 12.9 / torch 2.11 stack unchanged.
- graphify: nixpkgs' pybloomfilter3 0.7.3 ships sdist metadata that still
says 0.7.2, tripping pythonMetadataCheckPhase; skip that check only.
All 22 packages build and `nix flake check --no-build` passes.
Pin upstream llama.cpp b9645 and build it against the nixpkgs-latest
input (the flake's pinned nixpkgs only carries the pre-tools/ui b8983).
ROCm deps come from rocmPackages.gfx1151, so clr/rocBLAS/hipBLAS are
built for gfx1151 only; clr's own build is arch-independent, so its
store path stays substitutable. Vulkan on, CPU variants with znver5 /
AVX-512, web UI and npm toolchain dropped.
Ported from nixos-config's llm-engine.nix with two fixes: npmConfigHook
hard-fails when npmDeps is null, so nodejs and the hook are stripped
from nativeBuildInputs, and CMAKE_HIP_FLAGS is appended to
cmakeFlagsArray because the cmake hook word-splits plain cmakeFlags.
Verified on the Radeon 8060S (gfx1151): llama-bench loads both ROCm and
Vulkan backends and completes pp16/tg8 runs.
Package FreeToken (FlashML-org/FreeToken) — edge-native MoE serving
engine with OpenAI/Anthropic-compatible APIs, serving the `ft` CLI.
- torch-bin 2.11 (CUDA 12.9 wheel build) satisfies the torch>=2.11,<2.12
pin; extensions link the same cudaPackages.cuda_cudart via a synthetic
CUDA_HOME (cudart headers + nvcc crt/ headers, no nvcc needed).
- flashlib==0.3.0 vendored from the PyPI wheel (Triton-only; freetoken
never imports the CuTeDSL GEMM backends, so nvidia-cutlass-dsl is
omitted via pythonRemoveDeps).
- apache-tvm-ffi overridden to the pinned 0.1.13.post3 with a vendored
cython 3.3.0 (build needs >=3.2.8, nixpkgs has 3.2.4); pytest skipped
(upstream runs pytest-xdist with GPU tests).
- Unfree (CUDA EULA) is self-scoped: the package re-imports nixpkgs with
config.allowUnfree so no flake-level or user config change is needed.
- Optional accel extras (flashinfer/sglang-kernel) and the kernel-cache
wheel are not packaged; runtime falls back to pure-Triton kernels.
- Verified: nix build .#freetoken, ft --version, python imports check,
extension RPATHs.
Traycer is an open-source AI orchestration desktop app (Electron).
Packaged from the upstream AppImage via appimageTools.wrapType2,
matching the existing loop package pattern.
Web interface to manage nftables rules with drag-and-drop rule creation.
Upstream source is incomplete (missing settings crate, no GUI build
tooling), so the package builds the Rust workspace from the pinned
commit with a patched-in settings crate (schema recovered from official
release artifacts) and reuses the prebuilt GUI from the hash-pinned
release tarball on nftablesbuilder.eu.
- Add LD_LIBRARY_PATH to wrapper so Electron GPU process finds bundled libEGL.so.1
- Add glib.bin to buildInputs and wrap gsettings into PATH
- Create versioned symlinks for bundled libEGL.so and libGLESv2.so
- Clean up formatting in package inputs
Add freebuff v0.0.85 from npm registry — a pure JS CLI tool for
AI-assisted coding. Pre-fetches all transitive npm dependencies to
work within the Nix sandbox (no network access during build).
Replace fetchurl + prebuilt binary with buildGoModule + buildNpmPackage
to compile radar natively from source. Frontend (React/Vite) is built
as a separate derivation, then embedded into the Go binary via go:embed.
Also patches the npm lockfile to add missing resolved URLs for
workspace packages that lacked them, enabling proper dependency fetching.
Closes nix-overlay-qlc
