Microsoft introduced MAI-Thinking-1, a 35B parameter MoE model with 256K context, achieving 97% on AIME 2025 and outperforming Sonnet 4.6 in human preference tests. The broader 7-model MAI family spans reasoning, code, image, speech, and voice, with third-party availability on OpenRouter, fal, and Baseten. The detailed 109-page technical report revealed insights on scaling, MFU, RL/post-training, and data curation, highlighting no third-party distillation and advanced prompt optimization techniques. Microsoft emphasized agent-native devices and local inference with projects like Project Solara / Scout and the Surface RTX Spark Dev Box, alongside software innovations such as the Copilot desktop app and MAI-Code-1-Flash integration. Meanwhile, local-first computer-use agents like Holo 3.1 (Qwen-based, 0.8B to 35B parameters) support laptops and small workstations with optimized formats and strong benchmark results. Desktop shells for agents, including Hermes Desktop, Devin Desktop, and agent-neutral approaches compatible with Devin, Claude Code, and Codex, are proliferating, with hybrid local/cloud execution becoming the default architecture as seen in Perplexity Computer's hybrid agentic inference.
3x in 3 months: Cursor @ $28b, Cognition + Windsurf @ $10b

Cursor is reportedly fundraising at a $28 billion valuation with $1 billion ARR, while the combined Cognition+Windsurf entity is fundraising at a $10 billion valuation after acquiring Windsurf remainco for $300 million. The competition between AI coding agents intensifies as Cursor focuses on Async SWE Agents and Cognition+Windsurf acquires an agentic IDE. Alibaba's Qwen3-Coder gains widespread adoption for coding tasks and integration into tools like Claude Code and LM Studio. OpenAI rolls out ChatGPT Agent to all Plus, Pro, and Team users, sparking discussions about an "agentic economy" emphasizing AI literacy. Anthropic's Claude Code is praised as a premier development tool with active community feedback. Perplexity's Comet browser assistant receives positive reviews and new feature showcases. The debate continues on whether AI coding tools will replace developers, with critiques highlighting the ongoing human effort required. A new minimalistic software engineering agent, mini, achieves 65% on SWE-bench with just 100 lines of code.

Cognition is acquiring the remaining assets of Windsurf after a significant weekend deal. Moonshot AI released Kimi K2, an open-source, MIT-licensed agentic model with 1 Trillion total / 32B active parameters using a Mixture-of-Experts architecture, trained on 15.5 Trillion tokens with the MuonClip optimizer, showing top performance on benchmarks like EQ-Bench and Creative Writing. xAI launched Grok-4, ranking 5th on IQ Bench but with notable quirks including a bug causing it to respond only with "Heavy" and a high frequency of Elon Musk mentions. Rumors about OpenAI delaying an open-source model release surfaced, with speculation about CEO sama's PR strategy and a possible GPT-5 launch in September. The Gemini 2.5 paper was released with 3,295 authors, and Google introduced its Gemini Embedding model, topping the MTEB leaderboard.
