 ## When to Choose Codebuff
 
 Codebuff might be a better choice if you value:
 
-- Speed and Cost: Codebuff is [nearly 4 times faster](https://x.com/jahooma/status/1894224663817195599) and half the cost of  than Claude Code for equivalent tasks
-- Resource Usage: [Lower CPU utilization](https://x.com/brandonkachen/status/1894108912279752979), no constant console clearing
-- Holistic Codebase Analysis: Codebuff pulls more context from scanning your entire codebase, rather than file-by-file. Codebuff also [blends different models](/docs/advanced#what-models-do-you-use?) based on their strengths to provide more accurate results.
-- Edit Precision: Makes targeted edits instead of [complete file rewrites](https://x.com/skcd42/status/1894158600513155297)
+- Speed: Codebuff is [nearly 4 times faster](https://x.com/jahooma/status/1894224663817195599)

 - Staying in Flow: Codebuff requires fewer confirmation prompts for file edits and command execution.
+- Focused changes: Codebuff does just what you asked for, while Claude Code will often get carried away editing more and more files.
 
 ## When to Choose Claude Code
 
 Claude Code might be a better choice if you:
 
 - Can't use an intermediary provider, need to use the API directly from Anthropic
-- Prefer usage-based pricing for occasional use

 Codebuff starts by running through the source files in all subdirectories and parsing them with tree-sitter. We use this information to help find relevant files to you requests.

-- `--lite`: uses Claude 3.5 Haiku for editing instead of Sonnet (~1/3 the cost). It also pulls fewer files, meaning that the context cost will be much smaller.
