MacBook unified memory can run bigger LLMs, but sustained use hits 100°C
anantshri · reddit · 2026-07-27
A Reddit user reports that running large LLMs on a MacBook with unified memory quickly drives the machine to around 100°C, and asks whether people are really running these setups continuously or just “benchmaxxing.”
- The poster is experimenting with loading very large models on a MacBook Pro using unified memory.
- In practice, sustained inference causes severe heat and makes the laptop reach about 100°C.
- They are looking for a smaller model that can stay running all the time and act as the “brain” behind an agent like HermesAgent for simple tasks such as to-do lists and calendar management.
