MENGENAI EPISOD INI
The AI industry packed an unusual amount into a single week, and this Sunday wrap-up covers the developments from September 28 through October 4, 2026 that say the most about where the industry is heading.
Anthropic opened the week on September 28 by releasing Claude Sonnet 5.5, which Anthropic says runs more than 30% faster than Sonnet 5 and costs up to 30% less for most work, with a large reported jump on Terminal-Bench, an agentic-coding evaluation. The next day, OpenAI held its DevDay, introducing GPT-6.1 Sol for coding, computer use, and professional work, a public beta of its Agents API with hosted execution and multi-agent capability, and dots, always-on agents that keep working between conversations on their own cloud computer. OpenAI also added computer use to the Agents API, letting an agent operate software through its interface rather than a dedicated API, and GitHub followed on October 1 by putting Copilot's own computer-use feature into public preview for Windows and macOS.
Google released Gemini 4 Argon on September 30, its new frontier model with a 1-million-token context window, initially available through a program for trusted cyber defenders. The same week, NVIDIA announced an Open Agent Safety Platform combining OpenShell, an open-source runtime that traces and enforces policy on agent actions, with Sentry, a watchdog that quarantines agents that move outside their boundaries.
On the policy side, President Trump signed an executive order on September 29 titled "Inaugurating the Era of Super Intelligence," directing federal agencies to define the term "Super Intelligence," or SI, and to replace "artificial intelligence" with it in official communications. The administration separately announced a voluntary agreement with major AI companies covering internal controls, outside auditing, and board oversight of AI safety.
Taken together, the episode argues the week marks a shift from model releases toward full systems: agents that remember tasks, use tools, operate software, and keep working after a person steps away, raising new engineering problems around permissions, sandboxing, and control.
