Anthropic’s rumored Opus 5 could ship with a 1 million token context window

The post claims that Anthropic’s next Opus model will support a 1 million token context window.
It is presented as a rumor rather than an official announcement, so it should be treated as unconfirmed. Still, if true, it would be a major step in long-context capability and would likely affect how people think about document-heavy and agentic workflows.
