Merged summary

TL;DR - Open-source coding-agent harness Pi has added native DeepSeek support and reportedly achieves exceptionally high prompt-cache reuse, substantially reducing agent task costs. It highlights how harness design can materially affect the efficiency of the same underlying model.

  • Pi defaults to four tools—file reading, writing, editing, and command execution—while exposing advanced capabilities through extensions and skills.
  • Its append-oriented, stable context structure reportedly delivered 99.93–99.97% cache-hit rates with DeepSeek.
  • A Composio comparison found Pi’s average cost per successful DeepSeek V4 Flash task was about $0.028, versus roughly $0.195 for Claude Code.
  • DeepSeek is reportedly assembling an internal team to build an official coding harness positioned against Claude Code.
