How this term appears in the material In this channel's material, mega prompt comes up in the context of a live vibe check on OpenAI's Codex Spark, exploring what a super-fast model changes about AI coding speed — and where speed helps versus where a smarter model still wins [^8a401be3-f56a-5934-a449-63d1e01a151d@0]. The notes behind the video draw on a live session with Dan and Kieran, plus what they explored directly with the OpenAI team the day before the stream. Treat this entry as a pointer to that discussion rather than a standalone tutorial on prompt engineering.
