Xiaomi releases open-weight MiMo-V2.6-Pro model, tops intelligence index

Xiaomi open-sourced two multimodal models: MiMo-V2.6 Pro and Flash. Pro scored 46 on the Artificial Analysis Intelligence Index—the highest among open-source models—and matches Claude Opus 5 and GPT-5.6 Sol on most agent benchmarks. The post doesn't disclose parameter counts, training cost, inference latency, or the exact open-source license, so I'd hold off on production assumptions for now.

Xiaomi released the MiMo-V2.6 series. The Pro version ranks #1 among open weights models on the Artificial Analysis Intelligence Index with a score of 46, at a training cost of $3M. A Flash variant targets efficiency, and an UltraSpeed variant offers 20x faster output. The technical report details RL scaling across three axes: larger batches and throughput, richer multi-task environments, and more grader compute. Code and training recipes are open-sourced, but the 7k+ task datasets are not yet released. Former DeepSeek engineer Fuli Luo, now at Xiaomi, previously live-streamed the training runs.

Artificial Analysis ranks Xiaomi's MiMo-V2.6-Pro #1 out of 114 models with a score of 46. It's a 1T total / 42B active parameter open-weight model with text, image, speech, and video input. Output speed is 125 tokens/sec, but it's verbose—generating 140M tokens during evaluation. Pricing: $0.43/M input, $0.87/M output; the full eval cost $206.66.

Xiaomi released two omni-modal models: MiMo-V2.6-Pro and Flash. The Pro version scored 1628 on Code Arena WebDev, up 153 points from MiMo-V2.5-Pro's 1475, landing around 10th overall and ~3rd among open-weight models under MIT license. The post doesn't disclose Flash's benchmark numbers or parameter counts.

Xiaomi released MiMo-V2.6-Pro, scoring 46 on the Artificial Analysis Intelligence Index—up from 26 for the previous V2.5-Pro. It's now the highest among open-weight models. The post doesn't disclose parameter count, architecture details, or a release timeline.

Xiaomi MiMo dropped two fully multimodal open-source models. The Pro version matches Claude Opus 5 and GPT-5.6 Sol on most agent benchmarks and scores 46 on the Artificial Analysis Intelligence Index—the highest among open-source models so far. Capabilities span coding, computer use, 3D reasoning, and creative tasks. The post doesn't disclose parameter counts, training details, or where Flash sits in the lineup, so I'd hold off on direct comparisons for now.

Xiaomi MiMo-V2.6-Pro scored 46 on the Artificial Analysis Intelligence Index, the highest among open-weight models. The previous MiMo-V2.5-Pro scored 26. The post doesn't disclose model size, training data, or release license, so hold for details.
