Meta's Watermelon Matches GPT-5.5 Benchmarks (3 minute read)
Meta's superintelligence chief, Alexandr Wang, says that the company's upcoming model has caught up with OpenAI's GPT-5.5 on closely followed AI benchmarks. Codenamed Watermelon, the model is still in training. The model reportedly uses an order of magnitude more compute than Muse Spark. Meta has not given a timeline for Watermelon.

Autoresearch, Claude, and Constrained Optimization (13 minute read)
Many folks claim to be able to use AI to do the work of dozens of people. This researcher used autoresearch to work on a problem where the path from unknown to success is a clear, gradient optimization. The researcher found the auto-research/loop style of work makes sense for problems with a robust, measurable, and well-constrained metric to optimize. However, finding a problem with these factors is often tricky.

Residual Context Diffusion Language Models (2 minute read)
State-of-the-art block-wise Diffusion Large Language Models (dLLMs) rely on a remasking mechanism that decodes only the most confident tokens and discards the rest. Recycling computation from the discarded tokens is beneficial, as these tokens retain contextual information useful for subsequent decoding iterations. Residual Context Diffusion is a module that converts these discarded token representations into contextual residuals and injects them back for the next denoising step. It consistently improves frontier dLLMs in terms of accuracy with minimal extra computation overhead across a wide range of benchmarks.

Introducing Devin Security Swarm (3 minute read)
Devin Security Swarm is a cost-effective and accurate way to find security vulnerabilities in complex codebases. It uses a new architecture for whole-codebase reasoning called Agentic MapReduce. Devin maps relevant signals across a repository, fans out focused agents over bounded shards, reduces their findings to one report, then verifies serious vulnerabilities in isolated sandboxes before marking them confirmed. Cognition has published extensive documentation and technical materials about Agentic MapReduce.
