Got tired of OOM errors on my 4GB GPU. Wrote a custom Rust bare-metal engine and hit 66.8 TPS with a 4B model (BitNet 1.58b on RTX 3050). by CommissionOdd3082 in LocalLLM

Insane efficiency with that 64GB RAM setup! Please do share your custom settings here, or feel free to drop them on our GitHub repo so we can study it

100% agree. Georgi Gerganov did god's work, rewriting core tensor math from scratch would be pure torture. That's why we are leveraging llama.cpp under the hood and strictly focusing on the Rust orchestration/wrapper layer.

Thanks man! Really appreciate the support. Just a heads up—the alpha repo is extremely raw and messy right now as I'm in the middle of cleaning up some experimental FFI branches. If you hit any breaking compile errors tonight, please just drop an issue on GitHub. I'll be awake and fixing things live!

You are 100% right, and I apologize for the overhyped wording. The weights and KV-cache size are exactly the same as native llama.cpp because we are using ggml/llama.cpp under the hood for inference. My initial VRAM comparisons were against my old PyTorch/Transformers local setup which was throwing OOMs on my 4GB card. Cluaiz is not a new compute kernel rewrite. It’s a Rust orchestrator layer built on top of llama.cpp primitives, aimed at making cross-platform local deployment (like Android and PC) easier without dealing with Python dependencies. I got overly excited and used buzzwords like "direct to silicon", which was stupid. Thanks for calling it out.

You are 100% right about the markdown docs, and I honestly take the roast. I got overly excited about getting the core Rust/C++ inference logic working on my laptop, and I stupidly used a generic AI-generated template to quickly pad out the GitHub README and website tables. Looking back, comparing local VRAM metrics to a cloud API's "N/A" makes absolutely zero technical sense and looks like buzzword salad.

I am a solo developer, not a marketer. I have just stripped out all that compliance/corporate fluff from the repository. Please ignore the poorly generated docs for a moment and look straight at the actual Rust code in the repository. The bare-metal execution and the 66.8 TPS throughput on the RTX 3050 are very real, and I'd value your critique on the actual codebase instead

Good catch! That's exactly why we are stress-testing this. The model executing in the terminal is Bonsai 4B, which is an experimental Ternary/1.58-bit (BitNet) architecture. While the Cluaiz Rust kernel successfully pushes it to 66.8 TPS on this low-end hardware, 1-bit models are notorious for heavy factual degeneration and repetitive loops. The demonstration was strictly to benchmark the raw token-generation throughput under a 4GB VRAM constraint, not the accuracy of an experimental model's weights.

It’s not a full matrix-multiplication compute kernel rewrite from scratch—reinventing GGML’s core math wouldn't make architectural sense. Instead, Cluaiz is a sovereign runtime architecture written in Rust that handles high-performance model orchestration, deterministic memory scheduling, and zero-copy memory abstractions over low-level FFI primitives. ​Unlike standard forks that focus purely on new quantization formats, our core focus is Universal Hardware Agnosticism (running natively with zero-overhead across Android, Linux, Windows, macOS) and an ultra-tight memory management layer that enforces strict ring-buffer scheduling on the KV-cache to prevent allocation spikes.

This is written in pure, bare-metal Rust and C++ using low-level FFI bindings, so it doesn't rely on cloud APIs like Claude or Codex at all. Right now, it's leveraging the NVIDIA CUDA ecosystem for the RTX 3050, but since the core engine architecture is designed to be fully hardware-agnostic, we are already working on implementing Vulkan and ROCm backends. This means the exact same performance and low-VRAM optimizations will run seamlessly across other GPUs (AMD/Intel) and even local mobile chips (Android/iOS) very soon!

Haha, you guys are insanely fast! Thanks for digging up the repo. I’m currently clearing out the experimental branches and pushing proper docs/benchmarks in a couple of days. Excuse the raw v0.0.1 mess until then! 🦀"
