Tips for running Llama 3.3 70B

1 Q4_K_M needs ~41 GB — requires a 64 GB Mac with apps closed

2 Q2_K at 26 GB fits on 36 GB Macs but quality drops noticeably

3 Use DevPulse to aggressively free memory before loading: close Chrome, Docker, Slack

4 On 64 GB Macs, Q4_K_M is the sweet spot — run with DevPulse monitoring memory pressure

5 On 96 GB+ Macs, go Q6_K or Q8_0 for near-lossless quality

Skip the cloud GPU bill

Why pay $3/hr for an A100 when your Mac has unified memory sitting idle? DevPulse tells you if Llama 3.3 70B fits right now — factoring in Chrome, Docker, and everything else hogging your RAM.
