The pacman benchmark: finally a viable local agentic coding agent with Qwen 3.6 27b

One way I like to test new models, is by one-shoting (with a good prompt) a single webpage clone of the classic arcade game pacman. I usually do 3 attempts and keep the best one. So far all of them, including anthropic, chatgpt and google models, have failed, most of them miserably. The best one until now was GLM 5.1 That was until I tried it with Qwen 3.6 27b F16. Out of 3 attempts, 2 were the best by far, with the top result only having minor errors! However, as soon as I dropped to 8bit quantisation, I could not replicate those good results even after trying 5+ times.
