@PrismML @RunAnywhereAI is the first to run a 1 bit model on the @Qualcomm HNPU Team has been cooking, a lot more exciting things coming :)

@PrismML airplane mode for 27b is the biggest glow up i've seen in a while

@yoheinakajima @PrismML Omg, this tech is wild but feels kinda sketchy still.

@PrismML I’ve run 63 LLM slots on free tiers for months—PrismML’s 1-bit 27B on a phone is the real inflection. @yoheinakajima, how do you handle the latency spike when the model jumps from 3.9GB to 8GB in a live agent loop?

PrismML Releases Bonsai 27B: 1-bit and Ternary Builds of Qwen3.6-27B Hitting 89.5% of FP16 at 3.9GB. No new pretrain. No higher-precision escape hatches. No multi-GPU rig. Here's how it works. 👇 1: Codes, not floats Every weight becomes a code, with one shared FP16 scale per group of 128. Ternary is {−1, 0, +1}, binary is {−1, +1}. Sharing the scale across 128 weights keeps its cost at 16/128 = 0.125 bits. → Ternary: log2(3) + 16/128 ≈ 1.71 bits/weight → 5.9GB → Binary: 1 + 16/128 = 1.125 bits/weight → 3.9GB 2: Post-training, not from scratch No BitNet-style low-bit pretrain. It starts from off-the-shelf Qwen3.6-27B, architecture unchanged. The representation runs end to end across embeddings, attention projections, MLP projections, and the LM head. → 9.4× (ternary) and 14.2× (binary) vs the 54GB FP16 baseline 3: Labels are not bit-widths Conventional low-bit builds are mixed-precision by construction. The advertised name describes the most-compressed tensors, not the model. → Q4_K_XL, labeled "4-bit," is really 5.2 bits/weight at 17.6GB → IQ2_XXS, labeled "2-bit," is really 2.8 bits/weight at 9.4GB 4: Fitting a phone is two budgets iOS caps a single app near half of RAM, so a 12GB iPhone exposes ~6GB. The KV cache grows on top. Hybrid attention at ~75% linear means only 16 of 64 layers cache. → 4-bit KV: 4.3GB at 262K context, down from 17.2GB → 11.0 tok/s on iPhone 17 Pro Max 5: The numbers (15 benchmarks, thinking mode) → Ternary: 80.49 avg at 5.9GB — 94.6% of FP16 → 1-bit: 76.11 avg at 3.9GB — 89.5% of FP16 → IQ2_XXS falls to 57.5 on AIME26 while still scoring 88.93 on MMLU-Redux The key takeaway: 27B-class reasoning without the 54GB checkpoint — group-wise ternary and binary codes, an end-to-end low-bit language stack, 4-bit KV, on one phone.

bonsai 2 27b on an rtx 3060 12gb, the full receipt sheet. save this one, the 12gb row of the small gpu guide is built from it. speed by depth, then what context costs, live server, thinking on, real sessions > 7k deep: 24.4 tok/s > 12k deep: 21.9 tok/s > 35k deep: 17.8 tok/s > 77k deep: 13.0 tok/s > 64k window: 7.3gb resident > 128k window: 8.8gb resident > 192k window: 10.2gb resident > 262k window: 11.7gb resident, 0.6gb to spare, the whole native window on a 12gb card > every 64k of context costs 1.47gb, so 327k would not fit > a 41,312 token build session from 35k to 77k of context averaged 15.0 tok/s across 46 minutes > prefill 295 tok/s at 2k of context, 243 tok/s at 35k, first token in 0.6 seconds, fresh decode 26.1 tok/s > the card pinned 149 of 150 w the entire time, 78c, fan at 80%, power bound, not heat bound > 0.158 tok/s per watt at the fresh end the setup > model: ternary bonsai 2 27b, PTQ1_0, 1.75 bits per weight, 5.95gb on disk, base qwen 3.8 27b, apache 2.0 > runtime: prismml llama.cpp fork, prebuilt cuda 12.4 binary, no compile > serve: full 262k native window resident, q4 kv cache, flash attention, one slot, 11.7 of 12gb in use for anyone who followed bonsai 1 in july, that was the 3.9gb 1bit file at 42 tok/s on a 3060 ti, a faster card and a smaller file, so the same card comparison is not on the table yet, it comes with the 8gb test. what changed is the base, qwen 3.8 instead of 3.6, and the retention, 98.2% on their suite instead of 95%, and the whole 262k window fitting on 12gb.
