AA: MBZUAI open-weights K2 Horizon 375B A23B scores 47 with strong agentic results
Artificial Analysis benchmarks MBZUAI’s new open-weights MoE K2 Horizon 375B A23B (375B total / 23B active, 512K context) at 47 on the Intelligence Index—up sharply from dense K2 Think V2 (17). It leads nearby MiniMax-M3 on agentic/knowledge-work (GDPval-AA, τ³-Banking) but trails on hard reasoning (GPQA Diamond, HLE); ~26% hallucination rate is driven by abstention more than knowledge.

Ant Ling open-sources Ling-3.1-flash-1019: further post-trained 560B/25B-active MoE lifts AA Intelligence Index from 41 to 44, base checkpoint also released
On Oct 27 Ant Ling (inclusionAI) open-sourced Ling-3.1-flash-1019, a further post-trained upgrade of the early-October Ling-3.1-flash: 560B total parameters, 25B active per token, a 1M-token context and an MIT license. Ant says it scores 44 on the Artificial Analysis Intelligence Index v4.3.2 (up from 41), with clear gains on agent tasks such as AA-Briefcase and AutomationBench-AA. It also released Ling-3.1-flash-base, an open foundation checkpoint for further training.

Tencent Hunyuan open-sources Hy-SimulMT, a Chinese-English real-time simultaneous interpreting model with ~3s lag and live voice cloning
On Oct 26 Tencent Hunyuan (Tencent Hy) open-sourced Hy-SimulMT, a real-time simultaneous interpreting model for bidirectional Chinese-English speech-to-speech translation. It translates while the speaker talks, outputs both translated text and speech, and can clone the speaker's voice in real time. Six checkpoints landed on Hugging Face (30B-A3B translation-only and source-plus-translation Interleave variants, each in BF16, FP8 and GGUF), with the model card listing Apache-2.0; GitHub ships the SimulInfer serving stack and SimulTrain training tools. Vendor-reported: about 3s StreamLAAL on RealSI long-form audio, the lowest among compared systems.
