Rumor: Claude Opus 5 May Drop in 24 Hours—1M Context, Configurable Reasoning, Big Coding Gains

Leaks suggest Claude Opus 5 could launch within 24 hours, featuring a 1M token context window, configurable reasoning effort, significantly improved coding and agent performance rivaling GPT-5.6 SOL and Fable 5, better tool use and multi-step reasoning, and safety fallback routing. If Anthropic nails pricing and latency, the frontier model race gets more interesting.
