Arcee Trinity-Large-Thinking vs LFM2.5-VL

Arcee AI, a 30-person startup, has released Trinity-Large-Thinking — a 399B sparse mixture-of-experts reasoning model under Apache 2.0. Only 13B parameters activate per token, giving it inference speed 2-3x faster than comparable dense models. In internal benchmarks and early community testing, it ranks #2 on PinchBench, trailing only Anthropic's Opus 4.6, at a list price of $0.90/M output tokens — roughly 96% cheaper than frontier closed models. The model was trained in a $20M, 33-day run on 2,048 NVIDIA Blackwell GPUs. Arcee trained it using a constitutional AI-style process with synthetic chain-of-thought data generated from multiple frontier models, then applied a reinforcement learning phase using outcome-based rewards on math, code, and logic benchmarks. Trinity-Large-Thinking is the strongest open-weight reasoning model released to date on a commercial-friendly license. For companies with privacy requirements or custom deployment needs, it represents a credible alternative to frontier closed APIs — especially for code generation, mathematical reasoning, and structured data tasks where the gap between open and closed models has historically been widest.

Liquid AI just shipped LFM2.5-VL, a 450M-parameter vision-language model engineered from the ground up for edge deployment. Unlike most VLMs that require a beefy GPU in the cloud, LFM2.5-VL targets devices like the Snapdragon 8 Elite, NVIDIA Jetson Orin, and AMD Ryzen AI — hitting sub-250ms latency on-device without any cloud round-trip. This model builds significantly on its predecessor with four new capabilities: bounding box prediction (81.28 on RefCOCO-M), multilingual support across 8 languages, function calling, and improved instruction following. Those aren't just benchmark checkboxes — bounding box prediction means you can run visual grounding and object detection pipelines on a phone or robot without any server involvement. Liquid AI is the MIT-spun startup behind Liquid Foundation Models (LFMs), a non-Transformer architecture that delivers competitive performance at a fraction of the memory footprint. LFM2.5-VL is available free on HuggingFace and through Liquid's LEAP inference platform. For builders targeting on-device AI — robotics, mobile, embedded — this is one of the most practical releases of the month.
