Quantify the effect and attention cost of the accessible-mathematics cheat sheet

Determine how much the accessible-mathematics cheat sheet in Part IV of the v6m system instructions improves Gemini’s physics-video transcription performance and whether the sustained AI-attention cost of using the cheat sheet is low or modest.

Background

The v6m system instructions include an accessible-mathematics cheat sheet intended to guide Gemini toward LuaLaTeX constructions compatible with the amsmath, unicode-math, and siunitx packages while avoiding inaccessible or deprecated techniques. The authors acknowledge that they have not isolated or measured the cheat sheet’s contribution to transcription quality. They also remain uncertain about the attentional burden imposed on Gemini by the detailed instructions, despite observing no clear degradation in longer test videos.

References

We do not know how much difference this cheat sheet makes. We think, but are not certain, that the AI-attention cost is low or modest.
