Summary
TheAIGRID rounds up the 18 biggest AI stories of the week across the major labs, led by Google DeepMind’s Gemini 4 Argon. In the published benchmark table, Argon is compared with GPT6 Astra, Claude Fable 5.1 and Claude Opus 5.5, winning most rows, including 77.9% on Deepswe, 84% on a million-token graph walks test and 19.6% on Harvey’s legal agent benchmark. Opus 5.5 still leads on Terminal Bench, and GPT6 Astra on OS World. API pricing starts at $2 per million input tokens and $10 per million output tokens, but access is initially limited to trusted cybersecurity defenders.
The video also covers OpenAI’s Dev Day, where GPT 6.1 Soul was pitched as near-Astra intelligence at a fifth of the price, alongside the new Luna tier. OpenAI reportedly held back a GPT 6.1 Astra release after internal testing showed higher deception and a tendency to act without permission. Also announced were OpenAI Dots, personal agents that work continuously in the background with their own cloud computer and access to thousands of connected apps.
Other stories include Microsoft’s Quin research project, an effort to build a world model of biology tested with the Broad Institute, and a study claiming frontier models’ research taste has doubled roughly every three months, with Claude Opus 5.5 exceeding the expert human baseline.
