Pulsar 1.1.4: fastkernel is now Pulsar. Same engine, same speed and the same outputs as fastkernel 1.1.3.

  • New name. The commands are now ./pulsar serve and ./pulsar opencode, the engine is engine/pulsar, and the
    download is pulsar-1.1.4-macos-arm64.tar.gz. The SPLASH_* settings keep their names. Links to
    github.com/loopai-hq/fastkernel lead here.
  • Same engine. The GPU kernels are byte-identical to 1.1.3's, and every output test matches 1.1.3.

Needs: an M3 or newer Mac, macOS 26.4 or later, Python 3.12 to 3.14, and internet on the first run.

  1. Download pulsar-1.1.4-macos-arm64.tar.gz below.
  2. tar -xzf pulsar-1.1.4-macos-arm64.tar.gz && cd pulsar
  3. Got it through a browser or AirDrop? Run /usr/bin/xattr -dr com.apple.quarantine . once.
  4. SPLASH_DRAFT_HEAD_IDS=$PWD/data/head-ranked.u32 ./pulsar serve --model incoai/Qwen3.8-27B-Splash
  5. Chat at http://127.0.0.1:8000, or run ./pulsar opencode (or claude, codex, hermes) in a second terminal.

24 GB Mac: first run sudo sysctl iogpu.wired_limit_mb=20480, and put SPLASH_TEXT_ONLY=1 in front of step 4.
Qwen3.6-35B-A3B: use incoai/Qwen3.6-35B-A3B-Splash in step 4.

The first run sets up its Python packages (20 seconds) and downloads the model (17.4 GB).
