AILiquid AI released LFM2.5-VL-3B-DSpark, a speculative-decoding draft model for its LFM2.5-VL-3B vision-language model. The source reports decoding up to 2.66× faster on a single H100 with SGLang, up to 3.13× on Apple M5 Max with MLX-VLM, and up to 2.14× on Apple M3 Ultra with llama.cpp, with output unchanged under greedy decoding.

AIInferact, with Red Hat AI, NVIDIA, and Huawei, co-led an optimization effort that makes Kimi K3 on vLLM 2.2–2.8× faster. The work spans scheduling, KDA state handling, and custom MoE kernels. The vLLM project's background post cites those throughput gains on a B300 benchmark against v0.27.1 and links a technical deep dive.

AIOpenBMB's MiniCPM5-2B is a 2.5B-parameter model with native 128K context, offering hybrid Think and No-Think modes in one checkpoint. Users can download it from Hugging Face and run it fully offline on-device, as RunAnywhere demonstrated. In a demo, the model first called a puzzle impossible, then corrected itself and wrote a working verifier.

AIvLLM now supports NVIDIA hardware video decoding through PyNvVideoCodec, moving video decoding off the CPU so multi-GPU video captioning can scale to 8 GPUs. In benchmarks on 8xH100 GPUs, GPU-based decoding provides more than double the throughput of the CPU-based decoder for Qwen/Qwen3-VL-8B-Instruct with 8 single-GPU vLLM replicas. The functionality is included in standard CUDA vLLM releases, and PyNvVideoCodec==2.0.4 is required for custom installations.

AIOpenAI launched 47 community-built plugins for legal work in ChatGPT, created by legal experts from LegalQuants, Skills.law, and LECG rather than white-labeled by OpenAI.

The update adds RDNA1+2 support, ARM64 Windows CUDA support, faster GRPO, and FP8/INT8 image diffusion support for 2x faster inference.

AIinclusionAI has released Ming-Image-0.1-Design-Layer on Hugging Face, a model that decomposes a flattened design image into a requested number of RGBA layers using an image and a layer plan. The model runs at 1024 resolution (512 for faster processing) with 12 sampling steps, a CFG scale of 2.0, and BF16 precision on one CUDA GPU with 80 GiB VRAM. It is released under the MIT License.

AINortheastern University MS student Soham Padia used Ai2's open Olmo 3-32B model to build Steering Arena, a public game in which players submit text prefixes to steer prosocial behavior. About 600 submissions from a few dozen people showed the top 36 entries were unreadable token strings, while the best plain-English entry ranked 37th at about 2.7 times lower score. The results suggest that once an evaluation metric is exposed, it becomes an optimization target.

AIinclusionAI has released Ming-Image-0.1-Design, a 6B text-to-image model for UI, infographics, and posters that outputs RGBA images with transparent backgrounds. The model is available on Hugging Face and ModelScope under the MIT License. It runs at 2048 x 2048 with 12 sampling steps and a CFG scale of 1.0, validated on one CUDA GPU with 80 GiB VRAM.

AIOpenBMB says Dubedo is the kind of product it hoped VoxCPM2 would enable, citing speaker-aware cloning, multilingual generation, and an editing studio. The post praises @dubedostudio's work, while the background post describes Dubedo as dubbing into 30 languages with per-speaker voice cloning and a beta open for trial.

AISpeakeasy is open-sourcing its full OpenAPI client suite under the AGPLv3 license, including generators for seven languages (Python, TypeScript, Go, Java, C#, PHP, Ruby), an agent-native CLI generator, and a documentation MCP server generator. Google said the move followed the May 2026 shutdown of the SDK generation provider it had been using, which it cited as evidence that closed-source generators pose platform risk. Google's new Google GenAI SDKs for the Interactions, Agents, and Webhooks APIs were built with this pipeline across six targets.
