Google unveiled Gemini 4 Argon, its first frontier model in seven months, with initial access restricted to trusted cybersecurity partners. The model matches GPT-6 Astra in benchmarks but faces internal employee skepticism over performance.
Hark, which raised $700 million in Series A funding in May, has unveiled Handoff, an AI agent that can navigate and complete tasks on websites like Target, Walmart, OpenTable and LinkedIn without requiring APIs. The company claims its agent outperforms previous-generation frontier models including GPT 5.4, GPT 5.5, Opus 4.8, and Gemini 2.5 Pro.
A multi-domain evaluation suite for coding agents spanning four work domains — Code, Web, Office, and Security — with contamination-resistant task construction that reverse-engineers tasks from real commits and pull requests, released openly with full task directories, evaluation harness, and reference solutions.
Chinese AI lab Moonshot AI launched Kimi K2.7 Code, a one-trillion parameter open-weights coding model priced up to 12x cheaper than GPT-5.5 and Claude Opus 4.8, though it trails those models in performance benchmarks and lacks independent verification.
