Bonsai-8B is PrismML's latest model in their BitNet-inspired lineage — an 8.2B parameter language model that has been quantized end-to-end to true 1-bit precision (weights stored as -1 or +1), compressing the entire model to just 1.15 GB. That's roughly 12-14x smaller than a standard FP16 equivalent. Unlike post-training quantization hacks that lose substantial quality, PrismML trained Bonsai-8B with 1-bit arithmetic baked into the forward pass from the start. Benchmark results are competitive for the size class: 63.8 on MMLU, 72.1 on HellaSwag, and 54.2 on GSM8K — while running at 131 tokens/sec on an M4 Pro MacBook and 44 tokens/sec on an iPhone 17 Pro Max. That makes it the fastest locally-runnable 8B model in its weight class on Apple Silicon. The MLX-optimized weights are available on Hugging Face today under Apache 2.0. The significance goes beyond benchmarks. Getting a capable open-weight model to run at interactive speeds on consumer hardware — with no API key, no GPU, no cloud dependency — is a meaningful step toward truly private, offline AI. This follows PrismML's earlier "Ternary Bonsai" (1.58-bit) but represents a cleaner binary architecture that's easier to accelerate on custom silicon.

TurboQuant WASM ports the ICLR 2026 TurboQuant algorithm (Google Research) into a browser-native npm package using Zig, WASM, and WGSL compute shaders. It compresses embedding vectors ~6x (3–4.5 bits per dimension) and runs similarity search directly on compressed data — no decompression step. WebGPU acceleration delivers 30+ tok/s in Chrome. The demo shows Gemma 4 E2B generating Excalidraw diagrams from prompts with KV-cache compression cutting memory by 2.4x, enabling longer conversations inside browser GPU limits.
Reviewer scorecard
“131 tokens/sec on M4 Pro at 1.15 GB is genuinely impressive — I can embed this in a macOS app without any cloud dependency, no rate limits, no privacy concerns. The Apache 2.0 license means I can ship commercial products on top of it. This is the edge AI story I've been waiting for.”
“Searching directly on compressed vectors without decompression is a real algorithmic win, not a marketing trick. The npm package with embedded WASM binary means integration is literally one import. The Excalidraw demo proving KV-cache compression in-browser is compelling proof that this works in production-like conditions.”
“63.8 on MMLU is respectable but it's still noticeably behind mid-range cloud models on reasoning tasks. The GSM8K score of 54.2 means it'll fumble multi-step math that users expect to just work. Until 1-bit gets to 70B scale, it's a neat demo that falls short in production use cases where quality matters.”
“Chrome 134+ and WebGPU requirement kills a significant fraction of potential users — Safari and iOS aren't supported at all. This is research-grade code with 264 stars, not a production library. Zig as the core language also means limited community support if something breaks.”
“The trajectory here is what matters: 1-bit models are getting faster to train and competitive faster than expected. When custom Apple Neural Engine kernels land for BitNet-style weights, we'll see 200+ tokens/sec on a phone. Bonsai-8B is the proof-of-concept that makes that future feel real.”
“Browser-native LLM inference with compressed KV-caches is the path to private, local AI that actually fits in commodity hardware. TurboQuant is solving a memory wall problem that will matter more as models get longer context windows. The ICLR 2026 backing means the math is sound.”
“I've been looking for something I can embed in a creative writing or brainstorming app that doesn't require an internet connection. At 44 tokens/sec on iPhone, Bonsai-8B is finally fast enough to not break the creative flow. The 'no account required' angle is a genuine selling point for privacy-conscious users.”
“The Excalidraw diagram demo is legitimately impressive as a creative tool — prompt to architecture diagram in seconds, no server required. But until Safari/iOS support lands, this is a power-user curiosity. Most creative workflows aren't running on Chrome 134+ with WebGPU enabled.”
