The Silicon Base Flow platform has launched the open-source MoE model Kimi K2 developed by Moonshot AI. The model has a total of 1T parameters and 32B activated parameters, supports a context length of 128K, and performs excellently in coding and agent tasks. The pricing is 4 yuan per million tokens for input and 16 yuan per million tokens for output. New users can get 14 yuan in trial credit upon registration. The model has three technical advantages: 15.5T tokens of large-scale training, MuonClip optimizer for stable expansion, and design optimized for agent tasks. Tests show that it excels in coding

OpenAI announced the postponement of its first open-source large model release, with CEO Sam Altman stating that more time is needed for safety testing and risk assessment. This new model, which has performance comparable to o3-mini, may be named 'Open Model,' but the extent of its openness remains unclear. Research Vice President Aidan Clark emphasized that the company maintains strict standards for open source, as the model cannot be recalled once released. Although the delay disappointed some users, OpenAI believes ensuring safety and taking a responsible approach is more important. This decision will shape the future of models.

OpenAI announced the postponement of the open-source large model release. CEO Sam Altman stated that more time is needed for safety testing. The model was originally scheduled to be released this week but is now delayed until next week to ensure its safety and reliability. Altman emphasized that once the model is released, it cannot be recalled and must be handled with caution. This is OpenAI's first attempt to release a downloadable self-running model, aimed at providing powerful tools for researchers and small businesses. Although the delay is disappointing, the community generally understands the importance of safety testing and believes it is crucial for the AI ecosystem.

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.

The CEO of American AI company Perplexity publicly praised the newly released Kimi K2 model with one trillion parameters from Moonshot AI, stating that they may conduct training based on this model. Kimi K2 uses a mixture-of-experts architecture, showing excellent performance in tasks such as code generation, intelligent agents, and mathematical reasoning, and has achieved leading results in multiple benchmark tests. Perplexity previously used the DeepSeek R1 model, and this statement shows that they are actively seeking technological collaborations to drive AI product development. Kimi K
