On July 11, PixVerse AI video creation platform, which has surpassed 60 million global users, announced a major feature upgrade — the addition of the 'Multi-Keyframe Generation' function in the Start-End Frame module. This marks a new stage in AI video creation, transitioning from the generation of single segments to narrative expression. Users can now upload up to 7 images as keyframes via the web version's start-end frame feature, and the AI will automatically analyze the semantic relationships between frames, intelligently building smooth action and scene transition paths. This technological breakthrough enables static images to be presented dynamically.

Meta and Berkeley developed StreamDiT for real-time AI video generation: 1) 16fps 512p on single GPU, 4B-param model creates 1-min videos with live edits; 2) Novel buffer enables parallel processing (2 frames/0.5s) with 8-step optimization; 3) Trained on 3K HD videos + 2.6M dataset; 4) Outperforms rivals in motion smoothness, 30B-param version shows quality potential; 5) Enables interactive video despite transition flaws.....

Moonshot AI officially released its latest creation - the Kimi K2 model, and simultaneously announced its open source. This foundation model based on the MoE architecture has gained widespread attention in the AI field since its release, thanks to its strong coding capabilities and excellent general Agent task processing abilities. The Kimi K2 model has a total of 1T parameters, with 32B activated parameters. It has achieved top performance among open-source models in a series of benchmark performance tests such as SWE Bench Verified, Tau2, and AceBench.

Mistral AI launched the Devstral2507 series with two AI models: the open-source Devstral Small1.1 (24 billion parameters, SWE-Bench score of 53.6%) and the enterprise version Devstral Medium2507 (score of 61.6%). Small1.1 supports a 128k context window and local deployment, while Medium2507 outperforms some commercial models. Both are optimized for code reasoning and program synthesis, and support integration with agent frameworks.

Recently, the Ali Speech AI team announced the open source of ThinkSound, the world's first audio generation model supporting chain-of-thought reasoning. By introducing the chain-of-thought technology, this model breaks through the limitations of traditional video-to-audio technology in capturing dynamic visuals, achieving high-fidelity and strong synchronized spatial audio generation. This breakthrough marks a leap forward in AI audio technology, moving from 'image配音' to structured understanding of visual content.

Google releases the open-source tool MCP Toolbox for Databases, simplifying the integration of AI agents with SQL databases. The tool connects to a database with just 10 lines of code and supports secure mechanisms such as connection pool management, authentication, and schema introspection. It is compatible with various Google Cloud databases. As an open-source project, it lowers the development barrier, but currently mainly supports Google ecosystem databases. Future expansion of compatibility may be needed. This tool has the potential to become a standard component for AI development, driving intelligent data processing.

On July 7, the Tencent Hunyuan 3D team announced the launch of the industry's first art-level 3D generation large model, Hunyuan3D-PolyGen. By employing self-developed high-compression representation BPT technology and a autoregressive mesh generation framework, it enables accurate generation of complex geometric models with up to ten thousand faces. The model has breakthrough solutions for core pain points in 3D asset generation, such as poor topology quality, excessive face count, and difficulty in post-editing. It has improved the modeling efficiency of artists by over 70%. The relevant capabilities have been launched on the Tencent Hunyuan 3D AI creation engine and integrated into multiple game pipelines. Traditional

Tencent launched Hunyuan3D-PolyGen, the industry's first art-grade 3D generation model, using self-developed BPT technology to enhance wiring quality and complex object modeling. It generates high-precision geometric models, supports multiple surface types, and boosts gaming pipeline efficiency by 70+%.....
