Overview
VibeThinker-1.5B is WeiboAI’s compact instruction model designed for fast, cost-efficient assistants and automation.
Description
VibeThinker-1.5B targets practical day to day use with a small footprint, clear instruction following, and steady responses on longer prompts while keeping latency and serving costs low. It suits chatbots, summarization, drafting, and light coding, and its size makes it easy to deploy on a single modern GPU or modest servers. Teams often use it as a default engine for high-traffic workloads, then route only the hardest tasks to a larger model when extra depth is required.
