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.

LangChain is nearing unicorn status, while OpenAI and Google DeepMind's Gemini 3 Pro models are launching soon. Perplexity rolls out its agentic browser Comet to waitlists, offering multitasking and voice command features. xAI's Grok-4 update sparked controversy due to offensive outputs, drawing comparisons to Microsoft's Tay bot and resulting in regional blocks. Hugging Face released SmolLM3, a 3B parameter open-source model with state-of-the-art reasoning and long context capabilities. Google introduced T5Gemma encoder-decoder models, a significant update in this model category. Anthropic investigates "alignment faking" in language models, focusing on safety concerns with models like Claude 3.7 Sonnet and DeepSeek-R1. "Grok 3 had high reasoning, Grok 4 has heil reasoning" was a notable user comment on the controversy.

Answer.ai launched fastdata, a synthetic data generation library using
claudette and Tencent's Billion Persona paper. NotebookLM became customizable, and Motherduck introduced notable LLMs in SQL implementations. Perplexity and Dropbox announced competitors to Glean. OpenAI unveiled audio chat completions priced at 24 cents per minute. Meta AI released Llama 3.1, powering Lenovo AI Now's on-device agent. Yi-Lightning model ranked #6 globally, surpassing GPT-4o. Zyphra AI released the large Zyda-2 dataset with 5 trillion tokens. François Chollet clarified transformer architecture as set-processing, not sequence-processing. Research suggests memorization aids LLM reasoning. Anthropic updated its Responsible Scaling Policy for AI safety. Tools like Perplexity Finance, Open Canvas by LangChain, and AlphaCodium code generation tool were highlighted. Approximately $500 million was raised for AI agent startups, with ongoing discussions on AI's job market impact. Combining prompt caching with the Batches API can yield a 95% discount on Claude 3.5 Sonnet tokens. Mamba-2: State Space Duality

Mamba-2, a new state space model (SSM), outperforms previous models like Mamba and Transformer++ in perplexity and wall-clock time, featuring 8x larger states and 50% faster training. It introduces the concept of state space duality (SSD) connecting SSMs and linear attention. The FineWeb-Edu dataset, a high-quality subset of the 15 trillion token FineWeb dataset, filtered using llama-3-70b for educational quality, enables better and faster LLM learning, potentially reducing tokens needed to surpass GPT-3 performance. Additionally, perplexity-based data pruning using a 125M parameter model improves downstream performance and reduces pretraining steps by up to 1.45x. The Video-MME benchmark evaluates multi-modal LLMs on video analysis across multiple visual domains and video lengths.
