Intern-S1 Mini
Intern-S1 Mini is the compact member of Shanghai AI Laboratory’s scientific multimodal model family. It pairs an 8B language backbone with a roughly 300M vision encoder, retaining scientific question answering, diagram interpretation, and reasoning in a smaller deployment footprint than the 241B flagship. The release provides Apache-licensed weights and hosted inference. The official announcement dates the independently released Mini checkpoint to August 21, after the July 26 flagship. Its API documentation specifies a 32K context window.
