Anthropic says Opus 5.5 matches Opus 5 on agentic coding in about half the turns and output tokens at $4 and $20 per million tokens, and Pi can drive that model or a rival's through four built-in tools.
A developer essay titled "Goodbye Claude, Hello Pi" drew discussion on Hacker News on November 8. Pi is a minimalist, open-source terminal coding agent built by developer Mario Zechner. It works with several model providers and ships four b…
