RetroCraft的演示视频是使用Qwen 3.8 27B Q8_K_XL在双3090显卡上通过单个提示生成的。性能数据显示了不同的令牌生成速度，其中一个实例在3.50秒内达到了464.05 t/s，另一个则为77.38 t/s。…
The demo video above was created with a single prompt using Qwen 3.8 27B Q8_K_XL.
create me a single page, html/js/css GeoCities, Laser Wave, 80's retro, minecraft clone named RetroCraft. Embed it in a single go binary that serves the HTML page.
It took Opencode only a few minutes to write the code and it worked without an adjustments. There's going to be lots of posts and demos today but I wanted to show the actual pp, tok/s, tokens in/out, numbers for of the whole run.
llama-swap provides basic trajectory data and we can see that not every turn is has the same performance for prompt processing or generation:

It did A LOT of thinking... Here are my llama-swap settings. The run was done using Q3.8-27B-MTP:preserve-thinking-coding in OpenCode. I found preserving the reasoning tokens greatly improves the results.
