Local AI users debate speed vs. intelligence trade-off in LLMs

A discussion on the r/LocalLLaMA subreddit highlights the trade-off between model intelligence and inference speed for local AI deployments. Users suggest that once a model reaches a certain threshold of agentic capability, prioritizing faster processing speeds becomes more important than marginal gains in "smartness." The ideal balance is described as approximately 500 tokens per second for prefill and 25 tokens per second for decoding, with users preferring a slightly less capable but faster model if these speeds cannot be met on available hardware.
