GPT-5.5 (High) vs Beam 1.0
Which is better for the money: GPT-5.5 (High) by OpenAI 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
GPT-5.5 (High) scores 6.7 points higher (37.0 vs 30.3) but costs 11× as much to run the benchmark ($3411 vs $319; flagship vs mid-range cost classes). They are not alternatives at one budget: pick GPT-5.5 (High) when you need intelligence above 30.3, and Beam 1.0 when 30.3 is enough.
| Metric | GPT-5.5 (High) | Beam 1.0 | Difference |
|---|---|---|---|
| Intelligence (higher is better) | 37.0 | 30.3 | −18.1% Beam 1.0 is 18.1% less intelligent |
| Total AA cost (lower is better) | $3,410.76 | $318.73 | −90.7% Beam 1.0 is 90.7% cheaper |
| End-to-end time (lower is better) | 19.79s | 8.02s | −59.5% Beam 1.0 is 59.5% faster |
| Price per 1M tokens (in / out) | $5.00 / $30.0 | $0.40 / $1.20 | |
| Input modalities | Text, Image | Text |
Beam 1.0 vs GPT-5.5 (High): 18.1% less intelligence, 90.7% less cost to run the AA benchmark, and 59.5% faster end-to-end.
