Local coding agents face cost and performance challenges

A developer explored running coding agents locally due to concerns about API token costs, but found that while Qwen Code could build a UI, it struggled with debugging and was slower than cloud-based models like Claude Code and Codex. The experiment highlighted that local inference, while free of token charges, incurred significant costs in terms of time and retries, suggesting that cost savings are not guaranteed. The developer also noted that Qwen3-Coder-Next, despite its description for coding agents, had limitations in its ability to recover from execution failures and was not a direct fork of Gemini CLI as previously assumed.
