Qwen3.8 vs 3.6 Writing Ray-Tracers in BASIC: 3.8 Iterates Autonomously, 3.6 Needs Help
Ok-Breakfast1878 · reddit · 2026-08-16
Reddit user Ok-Breakfast1878 compares Qwen3.8-27B and Qwen3.6-27B on writing BASIC ray-tracing programs. He built an agentic harness allowing models to write BASIC, run, and iterate on images. Qwen3.6 required user input and often missed errors; Qwen3.8 autonomously iterated to good results. Both used unsloth UD-Q8KXL quants.
