Trade-off
Verdict
Depends on your budget
Beam 1.0 scores 8.8 points higher (30.3 vs 21.5) but costs 30× as much to run the benchmark ($319 vs $10.6; mid-range vs budget cost classes). They are not alternatives at one budget: pick Beam 1.0 when you need intelligence above 21.5, and GPT-6 Luna (Low) when 21.5 is enough.
| Metric | GPT-6 Luna (Low) | Beam 1.0 | Difference |
|---|---|---|---|
| Intelligence (higher is better) | 21.5 | 30.3 | +40.9% Beam 1.0 is 40.9% more intelligent |
| Total AA cost (lower is better) | $10.63 | $318.73 | +2898.4% Beam 1.0 is 30× more expensive |
| End-to-end time (lower is better) | 6.60s | 8.02s | +21.5% Beam 1.0 is 21.5% slower |
| Price per 1M tokens (in / out) | $0.10 / $0.50 | $0.40 / $1.20 | |
| Input modalities | Text, Image | Text |
Beam 1.0 vs GPT-6 Luna (Low): 40.9% more intelligence, 2898.4% more cost to run the AA benchmark, and 21.5% slower end-to-end.
