A developer building a real-time AI meeting assistant called LiveSuggest discovered that the language model, contrary to expectations, was not the primary bottleneck in their pipeline. While the LLM (GPT-5 mini) had a median time-to-first-token of 1.2 seconds, the speech-to-text transcription and a custom "gating" mechanism for deciding when to generate suggestions introduced more significant latency. The developer opted for a faster LLM over a more intelligent but slower one to meet real-time performance requirements. AI
