opencode agent on Qwen3.8-Flash-Next (Basalt, RTX 5090). opencode 1.18.23 coding agent driving Qwen3.8-Flash-Next (IQ3_S pack, 384k context) on the Basalt engine, both in one container on one RTX 5090 with 64 GB of RAM. Each session gets an empty directory; the agent can write and run code there. opencode itself (its terminal interface, in the browser, opened on the folder home) is on a second port. Needs no network (the model runs in the same container); serve it with --allow-external-network to let the agent install packages.
