DesignComfyUI launches Comfy Agent: describe what you want and it builds, runs and fixes the workflow next to youThe agent lives inside ComfyUI, knows the latest models and extensions, and works on the same canvas while you edit by hand. Available in Comfy Cloud since 1 October; the desktop version follows in a few weeks. It is a beta.FrontierGPT-6 Astra now has an Ultrafast mode: up to 8x faster generation, per NVIDIAThe mode runs on NVIDIA Blackwell and is available in the OpenAI API and to eligible ChatGPT Work and Codex users. OpenAI has no announcement of its own in its newsroom; the number is in NVIDIA's blog, with quotes from two OpenAI people, and in OpenAI's API documentation. OpenAI's documentation adds the condition that, for us, comes first: US or global processing only, no EU endpoints.ScienceStudy at Apple: a strong model with a minimal harness keeps up with elaborate agent scaffolding on an equal time budgetA paper published on Apple Machine Learning Research and on arXiv compares the best open-source harnesses for autonomous ML engineering with a single coding agent that has only read, write and bash. Under an equal time budget and the same model, the scaffolding gives no advantage. The authors conclude that hand-crafted harnesses around strong models yield poor returns.BuildersBarclays expects half of its developers to be using Claude Code by the end of the yearOn 1 October Anthropic said British bank Barclays is expanding their collaboration and rolling Claude out across the bank. Barclays expects Claude Code to reach 50 percent of its developers by the end of 2026 and a majority of its software engineers in 2027.FrontierGoogle releases Gemini 4 Argon to cyber defenders first, and without cyber brakesOn 30 September Google announced Gemini 4 Argon, its new top model. It is going to trusted defenders through the Fairwind programme, and for them and Google's internal teams it will come without cyber safeguards.

Improper handling of URI encoding lets a remote attacker bypass the check and reach the API as admin. There is no workaround, exploitation is active, and CISA set a deadline of 3 October.ControlOpenAI: people linked to Moonshot AI tried to extract its models' hidden reasoningOn 30 September OpenAI said it had disrupted a coordinated adversarial distillation campaign that began on 1 July. The company attributes the core of the activity to individuals associated with Moonshot AI, the developer of Kimi. No encryption was broken and there was no direct access to stored user conversations.ScienceDeepMind put a watermark inside the protein itself, without taking away its function in lab testsOn 30 September Google DeepMind introduced SynthID Bio, watermarking methods for synthetic biology. The signature goes into the choice of amino acids and into the 3D coordinates of predicted structures, and it can be verified even on the synthesised protein. In lab tests against three targets, watermarked proteins worked as well as unmarked ones.
