    Ollama shares LFM2.5-24B-A2B release and local run command

    Ollama shares the command `ollama run lfm2.5:24b`, quoting Liquid AI’s release of LFM2.5-24B-A2B for local agent tasks on laptops and PCs. Liquid AI describes a reasoning model with 24B total parameters, 2B active per token, and a context expanded to 131K tokens, with open base and post-trained weights on Hugging Face. https://ollama.com/library/lfm2.5:24b https://twitter.com/liquidai/status/2110055807194931348

    Why it matters: The distinction between 24B total parameters and 2B active per token provides context for Liquid AI’s positioning of the model for local agent tasks on laptops and PCs.

    HiRO-ACEv2 simulates extreme weather at 3 km resolution for a fraction of the cost

    Ai2 introduced HiRO-ACEv2, an updated climate emulator that generates global 3 km rain, wind, and pressure data at about 1/300th the cost of X-SHiELD. Given coarsened X-SHiELD data, its HiROv2 downscaling model matches high-resolution statistics to within 3%, even for events occurring once in a million data points. The system currently works only with ACE tuned to match X-SHiELD and cannot yet generate high-resolution data for other climates; downloadable models, tutorial notebooks, and a web demo are available.

    Why it matters: The comparison with X-SHiELD gives researchers a concrete cost and accuracy reference for extreme weather simulations, with applicability currently limited to the climate represented in training.

    Fish Audio’s Drama 3 Preview leads open-weights models in Artificial Analysis TTS rankings

    Artificial Analysis reports that Fish Audio’s Drama 3 Preview ranks #1 among open-weights models on all three of its Text to Speech leaderboards and leads all models in Pronunciation Robustness. It scores 93.2% on pronunciation robustness, ahead of Eleven v4 at 91.7% and Eleven v4 Turbo at 90.1%, while ranking #10 in Provider Voice and #14 in Controlled Voice. Its weights are available on Hugging Face under the Fish Audio Community License, and Fish Audio API pricing is $15/1M characters.

    Why it matters: The comparison separates pronunciation robustness from voice preference rankings, showing how Drama 3 Preview’s lead on one measure differs from its placement on others.

    Liquid AI releases LFM2.5-24B-A2B for fast, private on-device agents

    Liquid AI released LFM2.5-24B-A2B, an open-weight reasoning model with 24B total parameters and 2B active parameters, for on-device agents that reason and call tools. Its context window expands from 32K to 131K tokens, and both the reasoning and Base versions are available on Hugging Face. Liquid AI reports 184 tokens/s on an Apple M5 Max and competitive tool-use results, while acknowledging that larger models retain advantages on knowledge-heavy and coding benchmarks.

    Why it matters: The benchmark comparison helps distinguish workloads suited to local deployment, with strong tool use and instruction following alongside weaker knowledge and coding results than some larger models.

    Mixture-of-Experts kernel engineering on Amazon SageMaker AI

    AWS explains three fused MoE optimizations used in Amazon SageMaker AI, reporting up to 10 percent higher throughput and up to 9 percent faster Time to First Token (TTFT). On H200, swapping matrix operands improved throughput by 2–4 percent, while routing FP8 tensor-quantized models to Triton improved throughput by 10 percent. Eliminating unnecessary Triton JIT recompilation improved TTFT by 9 percent at 8-way tensor parallelism; the post identifies availability in vLLM and the AWS LMI v28 container.

    Why it matters: The optimization examples offer a transferable approach to MoE serving performance by examining matrix layout, backend selection, and compiler specialization as separate sources of throughput and latency overhead.

    Hugging Face author trains six models in two days with ML-intern, spending about $103 in total

    The author used ML-intern in HuggingChat, describing the requirements in prompts, to build six models in two days and publish them to the Hub, at a total compute cost of about $103. One project distilled the 9B prompt rewriter for Qwen-Image 2.1 into a 0.8B version that runs on a CPU, with a 99.7% valid-output rate and about one-quarter of the teacher model's token usage. The author published all seven prompts and recommends asking for baseline comparisons, smoke tests, and a budget cap.

    Why it matters: The author built six models in two days with ML-intern and published all prompts and cost details, offering an approach others can adapt to their own training workflows.

    Microsoft Research open-sources Agent Lightning v1.0, a 3,500-line lightweight agent RL framework for training with real harnesses

    Microsoft Research open-sourced Agent Lightning v1.0, a lightweight agent reinforcement-learning framework of about 3,500 lines. Its Harnessed Agentic RL approach lets the same agent harness used in deployment participate directly in reinforcement learning, without reimplementing the agent inside a training framework.

    Why it matters: The source gives the framework's code size, Kubernetes support, and training recipe, helping readers assess the cost of bringing a real harness into RL.
