Qwen 3.8 Flash Next Can Build Funny Games

This is nothing impressive but, i had so much fun i wanted to share my experience with this model. (yes this post is written by human) I made an FPS with local Q4_K_XL 3.8 Flash Next (256k context) (it took 3 days to refine everything but playable demo was ready in 2 hours) to play with friends. had ton of fun talking with them about what could we add , funny features etc. Features: - toggle retro psx shader - totally destructible environments - tac sprint - tilting with Q and E for peaking from corners. - free for all modes, SnD, Swords Only (swords have animations when slashing), RPG only, team deathmatch - killfeed, map with red dots when a player shoot - bunny hop - day and night cicle with rain or snow - fov slider / shader intensity slider - hide n seek mode I used opencode as harness, gun models were taken from sketchfab , model was running at 20tok/s avg with MTP, i know for someone is bad, but it did most of the work meanwhile i was at work or while sleeping, checking every now and then with a remote KVM from phone. My machine: 5900x / 128GB DDR4 3200Mhz / RTX 5090 and RTX 4000 PRO (32 + 24 GB) What games you would like to build in free time with ai? roguelites? 2d platforms? racing games? Or did you already built something? share with some screenshots submitted by /u/zRevengee [link] [comments]

UPDATE: Qwen3.8-Flash-Next on 2x3090 + DDR4 (Part 2): 25-29 -> 37-41 t/s decode (UD-Q4_K_XL + expert cache + MTP), plus a branch you can build
My Qwen3.8-Flash-Next recipe for single GB10/DGX Spark, uses Intel AutoRound int4 quant and vLLM, fp8 ngram table offloaded to local SSD or external RDMA server. At mtp=3 c=1, code is ~47.5t/s, json is ~60t/s. Prefix cache is ON.
