GLM-5.3 (Max) vs Beam 1.0
Which is better for the money: GLM-5.3 (Max) by Z AI or Beam 1.0 by Reflection? Intelligence, total benchmark cost, and end-to-end time from Artificial Analysis & other sources, snapshot 2026-10-24.
Trade-off
Verdict
Depends on your budget
GLM-5.3 (Max) scores 14.5 points higher (44.8 vs 30.3) but costs 7.9× as much to run the benchmark ($2503 vs $319; flagship vs mid-range cost classes). They are not alternatives at one budget: pick GLM-5.3 (Max) when you need intelligence above 30.3, and Beam 1.0 when 30.3 is enough.
