Opencode config for maximum parallelism

Hi, recently, I started using Opencode. I'm running a local server with 3x AMD MI50 (32GB), 2x Xeon with 16 cores each and 512GB RAM. For inference I'm using llama.cpp which provides API access through llama-server. For agentic coding tasks I use Qwen3-Coder-Next which is working pretty fast, since it fits in the VRAM of two MI50 including a context of 262144.
