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.

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
“A #2 benchmark result from a 30-person startup under Apache 2.0 is legitimately shocking. The sparse MoE architecture means you can run 399B at a reasonable cost — and $0.90/M output is almost too cheap to believe for this performance tier. This is going in our eval suite immediately.”
“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.”
“Benchmark numbers from the releasing company always look better than real-world deployment. PinchBench is also relatively new and the community hasn't stress-tested whether it correlates with production quality. Wait for independent evals before betting a product on this.”
“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.”
“This is the model that closes the open vs. closed frontier gap. When a 30-person startup can train a near-frontier reasoner for $20M on a commercial license, the economics of AI completely change. Enterprises that couldn't afford frontier APIs will rebuild their stacks around self-hosted models like this.”
“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.”
“For long-form creative work requiring multi-step reasoning — worldbuilding, complex narrative planning, detailed research synthesis — a 399B model at this price point is transformative. The chain-of-thought always-on design means it actually shows its reasoning, which helps when I need to redirect it mid-task.”
“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.”
