HIGHLY EXPERIMENTAL! Put this in .amp/plugins/deepseek-v4.ts to try DeepSeek V4 Pro in Amp (running on Baseten on USA-based servers).

A developer has released an experimental plugin integrating DeepSeek V4 Pro into the Amp code editor, running on Baseten's USA-based servers. The plugin creates a coding agent with high reasoning effort that can modify codebases, run verification, and access the full Amp toolset including file editing, web search, and subagent tasks. Users can activate the mode by placing the plugin file in `.amp/plugins/deepseek-v4.ts` and reloading plugins with `ctrl-o`.
