Solar Mini 4 的实际激活参数量是多少？
推理时仅激活3B参数，尽管总参数量为35B。
它是否支持超长文本输入？上下文长度具体是多少？
是的，支持最长524,288 token的上下文窗口（即524K）。
该模型主要适用于哪些类型的任务？
专为智能体（agentic）用例设计，包括多步推理、生成结构化输出及与工具协同。
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
