Richard and Pierce break down all the new AI web browser entrants with a particular focus on OpenAI's new Atlas, tradeoffs between vision models and text based dom parsing, potential security vulnerabilities, and more.

OpenAI releases their long awaited browser Atlas, Pytorch releases their distributed computation framework Monarch, the SALT reinforcement learning addition to GRPO, the HAL benchmark for agent evaluation, and trying to adapt the kv cache for text diffusion models.

Richard and Pierce take the bull case on whether we're in an AI bubble. They cover circular financial deals, energy build outs, AI representing 92% of GDP growth in H1 2025, and a comparison with the hype in 2000s around meaningless dot-com companies.

Articles written by LLMs have stabilized at exactly 50% of the internet (at least - so far as our classifiers can discriminate), the price of embedding models, OpenAI announces a new job board and certification programs for applied AI, Amazon releases the public availability of Bedrock AgentCore, and how pre-training on low quality data affects the capability of post-training.
