Beam 1.0 vs Hy4 preview
Values come from Beam 1.0 and Hy4 preview, 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.
- Weights
- Both publish weights — Beam 1.0 under Apache 2.0, Hy4 preview under Apache-2.0. Check the licences rather than assuming they permit the same commercial use.
- Recency
- Beam 1.0 shipped 49 days after Hy4 preview (2026-10-16 vs 2026-08-28).
