What Happened
Anthropic released Claude Opus 4.6 as an upgrade to its Opus-class line, emphasizing improvements in coding, planning, and sustained agentic work, and introducing a 1M token context window in beta for the Opus tier.
Why It Matters
Opus 4.6 reinforces the “long-context + sustained autonomy” frontier: the ability to reliably work inside large codebases and maintain coherence across long-running workflows is a differentiator for agentic tools.
