Trinity-Large-Thinking is a 399-billion-parameter open mixture-of-experts (MoE) reasoning model from Arcee AI, released under Apache 2.0. It's designed specifically for long-horizon multi-turn tool use and autonomous agentic tasks — thinking before responding with an explicit reasoning chain. The model ranked #2 on PinchBench (behind only Claude Opus 4.6) while costing $0.90/M output tokens via the Arcee API — roughly 96% cheaper than Opus. The full weights are freely downloadable from Hugging Face, making it one of the most capable openly-downloadable models available anywhere. Architecturally it draws on MoE efficiency to activate only a fraction of parameters per forward pass, enabling the massive 399B count without proportional compute cost. For teams building production agents that need serious reasoning but can't afford closed-model pricing at scale, Trinity-Large-Thinking is the most compelling open alternative that's appeared in a long time.

MiMo-V2.5-Pro is Xiaomi's latest and most capable AI model, released April 22, 2026. It combines a 1-million-token context window with multimodal capabilities — vision, audio, and text — in a single agent-ready model. On SWE-bench Pro, it resolves 57.2% of tasks, placing it near the top tier alongside GPT-5.4 and Claude Opus 4.6. What's genuinely surprising isn't the benchmark score — it's the efficiency. MiMo-V2.5-Pro uses roughly 42% fewer tokens than Kimi K2.6 at equivalent benchmark scores, and about 40–60% fewer tokens than comparable frontier models on ClawEval trajectories. That translates directly to lower API costs: the model is priced at approximately $1 per million input tokens. Xiaomi is best known for smartphones and consumer hardware, and MiMo represents a serious pivot into AI services. The company has been quietly building foundation model capabilities for two years, and MiMo-V2.5-Pro is the clearest signal yet that consumer hardware companies won't sit on the sidelines of the foundation model race.
Reviewer scorecard
“Near-Opus-level reasoning at $0.90/M tokens is the pricing inflection I've been waiting for. Apache 2.0 weights mean I can self-host for compliance-sensitive use cases. Already benchmarking it as a drop-in for my agent evaluation pipeline.”
“Frontier SWE-bench scores at $1/M tokens is a pricing inflection point. If you're building code agents and paying 3-4x that with other providers, MiMo-V2.5-Pro is worth a serious benchmark on your specific workloads. The 1M context window and multimodal support don't hurt either.”
“Preview weights and PinchBench rankings tell part of the story — real-world agentic performance on messy production tasks is another matter. Arcee AI isn't Anthropic or Google; sustaining a 399B model with quality ongoing RLHF is expensive and the preview label is a yellow flag.”
“Xiaomi has virtually no track record in enterprise AI reliability, SLAs, or developer ecosystems. Their API infrastructure is unproven under production load, and 'matching frontier benchmarks' on SWE-bench doesn't mean it'll perform comparably on your actual use case. Wait for the community to stress-test this in production.”
“A US-built, Apache-licensed frontier reasoning model competitive with closed offerings fundamentally changes the open-source AI landscape. The talent and capital required to do this was thought to only exist at the biggest labs. Arcee just proved otherwise.”
“This is what happens when smartphone makers with massive scale and tight efficiency cultures enter foundation models. Xiaomi's supply chain discipline maps naturally onto token efficiency. Expect more consumer hardware companies — Samsung, OPPO, others — to ship serious frontier-tier models within the next 12 months.”
“The thinking chain output is remarkably coherent for creative briefs and long-form narrative planning. At this price point I can run draft-then-refine pipelines at scale without budget anxiety. A genuine Ship for creative workflows.”
“Multimodal at $1/M tokens opens up use cases that were just too expensive before. Vision-capable agents at this price point mean small studios and solo creators can build real production workflows around AI vision without the cost anxiety of frontier model pricing.”
