1. AI Model Releases and Performance

1. Elon Musk announced that Grok 4.6 will be released around August 7, featuring 1.5 trillion parameters and significant improvements in SFT and RL. A few weeks later, Grok 4.7 with 2.1 trillion parameters will follow, offering better performance across the board but slightly slower service, with higher token efficiency. — via 1
2. Kimi K3, a 2.8 trillion MoE model, was released with native vision understanding and a 1M token context window. Its new architecture claims 2.5x intelligence per unit of compute. Key components including high-performance attention kernels, MoE communication library, and agent infrastructure are open-sourced. — via 1

2. AI Infrastructure and Security

1. Perplexity's Personal Computer feature transforms Windows PCs into AI agents by orchestrating local files, apps, and web agents for research, coding, browsing, and building. CEO Aravind Srinivas emphasized the unique value of local AI hardware and called owning a data center the new American dream. — via 1 2
2. Elon Musk joined the Open Secure AI Alliance, advocating for open-source frontier models and ecosystem to defend against AI attacks, as attackers already have frontier models. — via 1 2 3
3. According to DeepsecBench, Grok 4.5 offers the best cost-performance ratio in cybersecurity AI, being 10x cheaper than Sol, 5.7x cheaper than Opus 5, and 2.2x cheaper than Kimi K3, with performance close to Kimi K3. (Sol remains frontier.) — via 1

3. Product and Business Trends

1. Greg Isenberg identified "marketing agents" as the next big trend, similar to coding agents. They can autonomously run entire Facebook ad accounts including research, creative generation, publishing, and optimization. He also suggested building AI-native versions of popular WordPress plugins like Yoast, as there is clear demand and lack of competition. — via 1
2. WorkWeave, an AI model router that can reduce development costs by 40-70%, raised a $13.5 million Series A round led by Standard Capital. It has analyzed over 2 million PRs and is used by 25,000 engineers. — via 1 2
3. Strike now supports Apple Pay and Google Pay for Bitcoin purchases and added full German language support. The team also quickly implemented a privacy option to hide total purchase amounts after user feedback. — via 1 2
