LangChain ships SemIf decision model: structured classification via LLM Gateway
LangChain · x · 2026-09-22
LangChain released docs for SemIf (semif-qwen3.5-4b), a decision model served through the LangSmith LLM Gateway's System One API. Instead of generating chat text, it classifies or scores text and returns structured answers. It's free for US orgs on Free, Developer, and Plus plans through September 28, 2026, with a TypeSafe SDK (Python/JS) that lets you declare questions like ishelpful: Noul(...) and get typed structured results, plus cURL support.
