Reflection AI has released Beam 1.0, described as the highest-scoring US-based open-weight model on RuneBench. The cost-vs-performance chart places Beam 1.0 in the desirable top-left quadrant at roughly $0.8 per API run and 5.3 XP/min, in the same band as Qwen3.8 Max and GLM 5.3 — "looks solid out of the gate."
