Reflection 发布开源权重模型 Beam,对标中国开源模型并压低算力成本
Reflection AI 正式发布其首个前沿开源权重模型 Beam,称在高级推理基准上与中国领先开源模型持平,且推理算力消耗少 3-4 倍。Beam 为文本 MoE 模型,总参数 5010 亿、激活 230 亿,预训练 23.8 万亿 token,上下文窗口 100 万 token;对比 Z.ai 的 GLM-5.2 总参数约 7440 亿、激活 400 亿。公司称本月将公开权重与完整技术细节,并通过超大规模云厂商和 neocloud 分发,性能主张尚未经独立验证。
a lengthy blog post Monday , which described Beam as a text-only mixture-of-experts model trained on high-compute reinforcement learning to be effective at reasoning, coding, and agentic tasks at “a fraction of the token cost and inference time compute” of rivals. Beam is a 501-billion-parameter model with 23 billion active parameters. It was pretrained on 23.8 trillion tokens and has a 1 million token context window. To compare, Z.ai’s GLM-5.2 has roughly 744 billion total parameters with 40 b
