CodeGeeX vs CodeAssist
CodeGeeX and CodeAssist are the two cheapest ways to get AI help in the editor, with opposite pricing philosophies. CodeGeeX is free and open source: install the VS Code or JetBrains plugin and get completion, translation and chat across 20+ languages with no account and no bill. CodeAssist is pay-as-you-go at about $1 per credit (roughly seven generations per credit, three free credits on signup), offering a chat assistant and code completion inside VS Code and JetBrains; code is sent to its API for processing and not stored long-term (directory listings, October 2026; confirm on the official site). If you code daily, CodeGeeX's flat-zero cost wins outright. CodeAssist only makes sense for light, occasional use where a few dollars a month beats installing another extension — run your own usage math before committing. We did not hands-on test either product, so no quality winner is declared.

A hobbyist developer who opens the IDE a few evenings a month wants AI completions without committing to any subscription.
What a successful result must preserve
Track real monthly generations for two weeks first; the cheaper option is whichever side of the flat-zero vs pay-per-use line your usage lands on.
