MacBook Pro M5 Max performance questioned for local LLM coding

By PulseAugur Editorial · [1 sources] ·

A user on Reddit is inquiring about the practical performance of a 128 GB MacBook Pro M5 Max for local large-context LLM coding workflows. They are specifically concerned with prompt ingestion and prefill latency, rather than raw token generation speed. The user is interested in using models like Qwen 3.5-3.7 for coding tasks on large codebases and wants to understand performance metrics such as prompt processing speed, time-to-first-token (TTFT), and how performance degrades with context window size. AI

IMPACT Assesses the practical limitations of high-end consumer hardware for demanding local LLM applications.
