Show HN: OctoFlow–GPU-native lang, vibe-coded with human at every decision gate (opens in new tab)

Hi HN, solo developer here. OctoFlow is a GPU-native programming language — the GPU is the primary execution target, not an accelerator you opt into. 4.5 MB binary, zero dependencies, any Vulkan GPU.

  This is vibe-coded. LLMs generated the bulk of the code. That's not a caveat —
  it's the point. But "vibe-coded" doesn't mean "unreviewed." Every architectural
  decision has a human at the gate: pure Vulkan (no CUDA lock-in), zero external
  dependencies (hand-rolled everything), 23-concept language spec that fits in an
  LLM prompt, Loom Engine dispatch chains that let the GPU run autonomously.

  The AI writes code. The human decides what to build, why, and whether it ships.

  Two principles guide every decision:

  - Sustainability: Is complexity growing faster than it can be maintained? If the
    test count drops or the gotcha list grows, stop and fix before shipping more.

  - Empowerment: Can a non-GPU-programmer go from intent to working GPU code? If a
    feature makes the language harder for AI to generate, it doesn't ship.

  What's real today: 966 tests passing, 445 stdlib modules, 150 pre-compiled
  SPIR-V kernels, interactive REPL with GPU, AI code generation via
  `octoflow chat`. What's in progress: running 24GB LLM models on 6GB consumer
  GPUs via layer streaming.

  The stdlib and everything on GitHub is MIT. The compiler (Rust) is in a private
  repo for now, but the developer is willing to open-source all of it once there's
  a team to sustain it. Looking for co-maintainers — especially people with Vulkan
  experience or who care about keeping languages small and learnable.

  Happy to answer questions about the architecture, the vibe-coding workflow, or
  what it's like building a programming language with AI doing 90% of the typing
  and a human doing 100% of the deciding.
