反射光束在Ollama上可以自由使用，时间有限
2026年10月16日 (英语).
反射的第一个开放重量型号Beam(Beam)从今天上午开始普遍开放，与Reflection合作，Ollama的Beam端点以完全零数据保留(ZDR)运行。 您可以通过 Ollama Cloud 访问Beam，您可以从您的应用程序或终端运行支持的模型，而无需下载模型或管理本地推论。
Beam是一种混合专家模型，总参数约为5,010亿，每令牌活性参数为230亿，设计用于软件工程，推理，以及长视距代理任务。
Beam是为涉及不止一个响应的工作流程构建的：编写和维护代码，使用跨多个步骤的工具，以及随着时间的推移通过复杂的任务工作。 它的文本输入，文本输出设计侧重于这些工作量，其中代码，工具调用，日志，文件和结构化产出是核心。
Beam拥有100万个令牌上下文窗口，用于支持长期运行的工作流程。
Beam是Apache 2.0下的发布，给予开发者检查，定制和在模型上发展的自由。
你和Beam一起建造的东西
Beam是为下列工作量设计的：
- 编码 agents：解决软件工程任务，通过代码库工作，帮助编写和维护代码。
- 长期运行的agents：执行多步骤工作流程，使用工具，并努力争取一个超越延伸行动序列的目标。
- 数学和科学推理：处理复杂的数学和科学问题。
- 自定义模型：微调，并为特定应用定制一个开放量级模型。

Reflection's Beam is freely available on Ollama for a limited time
October 16, 2026
Reflection’s first open-weight model Beam is generally available as of this morning, and we’re day-zero partners rolling it out on Ollama for free (for a limited time only!). In collaboration with Reflection, Ollama’s Beam endpoint runs with full zero data retention (ZDR). You can access Beam through Ollama Cloud, where you can run supported models from your apps or terminal without downloading models or managing local inference.
Beam is a mixture-of-experts model with approximately 501 billion total parameters and 23 billion active parameters per token, designed for software engineering, reasoning, and long-horizon agentic tasks.
Beam is built for workflows that involve more than a single response: writing and maintaining code, using tools across multiple steps, and working through complex tasks over time. Its text-in, text-out design focuses on these workloads, where code, tool calls, logs, documents, and structured outputs are central.
Beam has 1 million token context window to support long-running workflows.
Beam is released under Apache 2.0, giving developers the freedom to inspect, customize, and build on the model.
What you can build with Beam
Beam is designed for workloads such as:
- Coding agents: Solve software engineering tasks, work through codebases, and help write and maintain code.
- Long-running agents: Execute multi-step workflows, use tools, and work toward a goal over an extended sequence of actions.
- Math and science reasoning: Work through complex mathematical and scientific problems.
- Custom models: Fine-tune and customize an open-weight model for specific applications.
