AI Weekly: Four Frontier Models in Four Days
Week of August 11 to 18, 2026 Four labs shipped frontier models within four days of each other this week, and every one of them was tuned for the same thing: agents that stay on task. SpaceXAI released Grok 4.6 and closed its Cursor acquisition, Google shipped Gemini 3.7 Flash at half price, DeepSeek took V4 Pro to general availability and then raised its prices, and Z.ai announced GLM-5.3 with…
Week eight of 2026 saw four Frontier labs release new models within a span of just four days. SpaceXAI's Grok 4.6, Google's Gemini 3.7 Flash at a discounted price, DeepSeek's V4 Pro moving to General Availability, and Z.ai's GLM-5.3 were all tuned for one thing - agents that stay on task.
Grok 4.6, a post-training upgrade over Grok 4.5, features a 500,000-token context window, a new xhigh reasoning-effort level, and tiered pricing. It shows promise in long-horizon agent tasks, scoring 61 on Intelligence Index and 1,577 on AA-Briefcase, both improvements over its predecessor. However, it lags behind in coding tasks.
Google's Gemini 3.7 Flash was priced to move, with an introductory rate of $0.75 per million input tokens and $3.75 per million output tokens. The model shows improvements in software engineering tasks and output speed. However, the price doubles after December 31, 2026.
DeepSeek's V4 Pro went GA and then increased its prices. This moves DeepSeek closer to the pricing models of their competitors.
Meanwhile, Z.ai introduced GLM-5.3, a model backed by claims of cybersecurity measures. However, the model details are not explicitly stated in the source.
