Beam 1.0 is Reflection AI's open-weight coding and agentic reasoning model, a sparse mixture-of-experts with 501B total and 23B active parameters, a 1M-token context window, and an Apache 2.0 license. Reflection reports 80.9% on SWE-bench Verified (self-reported), positioning it as a low-cost open option for software engineering and agent work.
Claude Haiku 4.5 is Anthropic's fast, affordable small model in the Claude 4 generation, balancing strong instruction-following and coding ability with low latency. It is designed for high-throughput agentic and chat applications where speed and cost efficiency are priorities.
