# I expected Claude Code to crush its open-source rival on my 16GB GPU, but that’s not what happened

**[XDA Developers](https://daily.dev/sources/xda-developers)** · 4 min read · 2 upvotes · 0 comments

## Summary

A local open-source coding agent matched Claude Code on a real task while costing far less. Running Qwen3.6-35B-A3B through OpenCode on a 16GB RTX 4070 Ti Super, the author built a GPU logger that passed all six requirements in 3 minutes 44 seconds, fully offline. Claude Sonnet 5.5 finished the same job in 2 minutes 42 seconds with better chart polish, but the session cost $0.37 versus roughly a fifth of a cent in electricity for the local run. The author calls the result a tie on utility and questions the value of a $20 Claude subscription for workflows that don't need flagship capability.

## Questions this post answers

### Can a 17.7GB Qwen3.6-35B-A3B model run on a 16GB GPU?

Yes, because it is a mixture-of-experts model activating only around 3 billion parameters per token, allowing optimizations like llama.cpp's --n-cpu-moe flag to offload 12 layers of experts to system RAM. This setup leaves room for a 128K context window while using about 15GB of VRAM on an RTX 4070 Ti Super.

_Developers eyeing local coding agents can track real GPU memory tricks like this on daily.dev._

### How does Claude Code compare to a local Qwen3.6 agent on coding tasks?

On a GPU logging task with clear pass/fail requirements, Claude Sonnet 5.5 via Claude Code finished in 2 minutes 42 seconds and Qwen3.6-35B-A3B via OpenCode finished in 3 minutes 44 seconds, both passing all six requirements without human intervention. Claude's session cost about $0.37 in subscription usage, while the local run cost roughly a fifth of a cent in electricity.
