New Claude 4 AI model refactored code for 7 hours straight
Briefly

Anthropic has launched Claude Opus 4 and Claude Sonnet 4, its most advanced AI coding models to date. Opus 4 is tailored for complex tasks and can function autonomously for hours, indicating a shift towards more agentic AI applications. This decision responds to increasing demands in the tech industry for intelligent solutions. The Claude model family, now featuring three tiers—Haiku, Sonnet, and Opus—offers varying balances of cost, speed, and capability, with Opus positioned as the most capable for deep, logical processing tasks.
"Across all the companies out there that are building things, there's a really large wave of these agentic applications springing up, and a very high demand and premium being placed on intelligence."
"I think Opus is going to fit that groove perfectly."
"Opus models process context more deeply and are hypothetically better suited for running deep logical tasks."
