GOMAXPROCS needs to be set in the server environment.

Oh, that did it! Thanks!
BTW, is there a way to convert to mlx quant and import?
If I specify -q mxfp8, I get Error: unsupported quantization type MXFP8 - supported types are F32, F16, Q4_K_S, Q4_K_M, Q8_0.

mlx runner failed: Error: unsupported architecture: Gemma4ForConditionalGeneration (exit: exit status 1) (status code: 500)
