Anthropic released Claude Opus 4.8 on May 28, 2026, six weeks after version 4.7. The model achieves 69.2% on agentic coding benchmarks (up from 64.3%), runs 2.5 times faster in fast mode at one-third the cost, while maintaining the same pricing as version 4.7.

Anthropic has released a fast-mode variant of Claude Opus 4.8 that delivers higher output speed at double the pricing of the standard version. The model offers identical capabilities to regular Opus 4.8 with input pricing at $10 per million tokens and output at $50 per million tokens.

Anthropic is preparing to release Claude Opus 4.7 and an AI-powered design tool for websites and presentations as early as this week, according to The Information. The announcement comes as venture capitalists offer valuations up to $800 billion, more than double the $380 billion valuation from February 2026.

The ARC Prize Foundation released ARC-AGI-3, an interactive benchmark requiring AI agents to explore environments, form hypotheses, and execute plans without instructions. All 135 environments were solved by untrained humans, yet frontier models—including Gemini 3.1 Pro Preview (0.37%), GPT 5.4 (0.26%), Opus 4.6 (0.25%), and Grok-4.20 (0.00%)—scored below 1%.
