PrismML's Ternary Bonsai is a family of aggressively quantized language models that take the BitNet concept to its logical extreme. Each weight is constrained to one of three values — {-1, 0, +1} — with a shared FP16 scale factor per 128-weight group. No higher-precision escape hatches, no hybrid layers. The result is a 9x reduction in memory footprint versus standard 16-bit models. The numbers are striking: the 8B model fits in 1.75 GB and hits 82 tokens per second on an M4 Pro. More impressively, it runs at 27 tokens per second on an iPhone 17 Pro Max — fast enough for real-time conversation on-device. The 8B variant scores 75.5 average across standard benchmarks, outperforming many models that are 9-10x larger. The 4B and 1.7B variants push further into mobile-optimized territory. All three models are released under the Apache 2.0 license, available on Hugging Face and GitHub, and integrated into the Locally AI iOS app for immediate on-device deployment. For developers building privacy-sensitive applications or anyone tired of paying cloud inference costs, Ternary Bonsai offers a compelling on-device alternative that doesn't require a beefy GPU.

Tiny Aya is a family of open-weight small language models from Cohere Labs designed to bring multilingual AI to devices that can't access cloud inference. The 3.35B parameter models cover 70+ languages including many lower-resourced ones — African languages, South Asian languages, and Asia-Pacific languages that larger multilingual models either skip or handle poorly. The family includes five variants: a base pretrained model, a globally balanced instruction-tuned version (Global), and three region-specific models — Earth (Africa/West Asia), Fire (South Asia), and Water (Asia-Pacific/Europe). The region-specific models are tuned on data distributions that reflect the linguistic needs of each geography, rather than averaging across all languages and underserving everyone. On the leaderboard for Product Hunt's April 5th, Tiny Aya landed in the top three despite being a research release rather than a commercial product. The models run on Ollama, are available on HuggingFace and Kaggle, and were trained on 64 H100 GPUs — a comparatively modest run for this level of multilingual coverage.
Reviewer scorecard
“82 tokens per second on M4 Pro in 1.75 GB is a genuinely impressive engineering achievement. For local tooling, code assistants, or any latency-sensitive workload where I don't want cloud round-trips, this hits a sweet spot that larger quantized models miss. Apache 2.0 means I can embed it in commercial apps without legal headaches.”
“Ollama support means this is running locally in ten minutes. The region-specific variants are a smart design choice — a model tuned for South Asian languages will outperform a globally averaged model on those languages even at smaller parameter counts. This is the right architecture for the problem.”
“A 75.5 benchmark average sounds good until you compare it against 8B models quantized with GGUF Q8 — which score similarly and have years of tooling, community support, and production deployments behind them. The 9x memory savings matter on constrained devices but less so on any machine with 16GB+ RAM. Niche but real use case.”
“3B parameters across 70+ languages means the average per-language capacity is thin. For high-resource languages like English, Spanish, or Mandarin, you're getting a model that's clearly behind purpose-built alternatives. The compelling use case is low-resource languages — but that's a narrow market compared to the general-purpose SLM space.”
“On-device AI at 27 tokens per second on a phone is the inflection point that makes LLMs a platform primitive rather than a cloud service. Once inference is this cheap and fast on commodity hardware, the entire economic model of AI-as-API-call collapses. Ternary quantization is an early signal of where efficiency research is heading.”
“The 5 billion people who don't speak English as a first language are the next wave of AI users — and they'll largely be on mobile, offline-capable devices. Tiny Aya is building the infrastructure for that wave. The region-specific model design suggests Cohere Labs is thinking seriously about this rather than treating multilingual support as a checkbox.”
“The prospect of running a capable LLM entirely on my iPhone without sending any data to a server is genuinely exciting for creative work with sensitive material. Drafting, editing, and ideation without a cloud subscription or privacy concerns — I'd pay for that, and here it's free.”
“For content creators working in non-English markets, an offline model that actually handles your language well is transformational. Offline translation and transcription with no API costs or data privacy concerns is a real workflow unlock — especially for creators in regions with unreliable connectivity.”
