Overview Updated October 24, 2026

IQuest Coder is a family of code LLMs focused on software engineering tasks such as code generation, refactoring, bug fixing, and multi‑file reasoning across large codebases.
It targets scenarios where teams want state‑of‑the‑art coding models that are fully open source, self‑hostable, and not tied to proprietary cloud APIs.
Key selling points include its Code‑Flow training paradigm, long 128K‑token context window, and specialized “Thinking”, “Instruct”, and “Loop” variants for different development workflows.
