Xiaomi Ships MiMo-V2.6 Pro and Flash
Pro claims parity with Claude Opus 5 on most agent benchmarks; Flash targets dual DGX Sparks.
@MiaAI_lab flags Xiaomi MiMo-V2.6-Flash at 309B parameters, 15B active, with native FP8 weights around 178 GB, sized for 2x DGX Sparks. Xiaomi MiMo's launch post says Pro "performs on par with Claude Opus 5 and GPT-5.6 Sol across most agent benchmarks." @plotarmordev calls Pro a contender for the best new model to run locally, with hardware requirements and real speed the deciding factors.
MiMo-V2.6-Flash-RL Benched on Two Sparks
Dual-Spark build posts 88 tok/s single stream, 156 aggregate at six streams.
@Tech2Wild ran MiMo-V2.6-Flash-RL 310B on 2x DGX Spark TP2 under vLLM with a DFlash checkpoint. Scores: 70 code, 69 math, 57 JSON, 26 prose, 85 structured tables, 88 tok/s single stream on counting. DFlash k=7 accepted up to 6.9 of 7 draft tokens per step on predictable text. The build serves a 1.87M-token fp8 KV pool at 300K context with 0.37s TTFT.
A 27B Model Aims at Everyday Writing
Altworld's 27B open-weights model tops its own blind writing benchmark and finishes third on public EQ-Bench 4.
Altworld released Hemmingway-1, a 27B fine-tune of Qwen3.8-27B under Apache-2.0 with 262,144-token context. On its own blind benchmark of eighty real requests, the model card says it beats GPT-6 Astra by fifty points and takes the hard-ask category 72% to 9%. It placed third on EQ-Bench 4, past GPT-5.5, Opus 4.7 and Opus 4.8. @MiaAI_lab says she will test it.
Grok 4.7 Undercuts Fable 5.1 on Price
@MiaAI_lab measures Fable 5.1 at 400% more for input tokens and about 733% more for output.
Grok 4.7 xHigh went live and @MiaAI_lab compares it with Fable 5.1 Max: Fable 5.1 costs 400% more for input tokens and about 733% more for output tokens. She puts Grok 4.7 at 80% to 88% less with a relatively small gap in coding performance. In the replies, @vishalsingh2972 computes 8.3x cheaper output and 5x cheaper input than GPT-6 Astra or Fable 5.1.
StepFun Previews a 600B Model With 27B Active
One million-token context with vision; ArtificialAnalysis rates it on par with Kimi K3.
@MiaAI_lab reports StepFun is back with a strong preview: 600B total parameters, 27B active MoE, 1M context with vision, tuned for coding, 3D and web design. ArtificialAnalysis puts it on par with Kimi K3 in intelligence, and Kimi carries over 4x as many parameters. Open weights are promised for October 15th.
Qwen3.8-Flash Update Serves 8 Streams on One Spark
New build posts 117 tok/s prose and 180 tok/s code with peak memory down to 91 GiB.
@Oluwaphilemon1 runs through the Qwen3.8-Flash update for a single NVIDIA DGX Spark: 117 tok/s prose, 180 tok/s code, 8 concurrent streams, optional NVIDIA NVFP4 support, and peak memory cut from about 101 GiB to 91 GiB. The build adds a 24/7 auto-restart supervisor and cached-token reporting in every response. In the replies, @ViC305 points to his EXL3 recipe as faster per stream.
