Beam 1.0 vs DeepSeek V4.1-Flash
Values come from Beam 1.0 and DeepSeek V4.1-Flash, where each is cited to its source. This page states no benchmark result and ranks neither model — it puts two published specifications next to each other. Where a lab has not published a figure, the row says so rather than guessing.

What actually differs
- Context window
- Identical — both accept 1M tokens, so context length is not a reason to pick either.
