Error Message

The request was malformed and could not be processed.
oMLX prefill memory guard rejected this prompt: Prefill would require ~55.12 GB peak (current 29.69 GB + KV+SDPA 25.43 GB) but metal_cap ceiling is 49.25 GB. Raise kernel iogpu.wired_limit_mb in Terminal (currently caps Metal at 51.84 GB), or reduce context length. To continue, set Memory Guard to aggressive, raise the custom memory guard ceiling, free system memory, or compact/reduce context.
