Seed-Coder-8B

Open-source 8B code-LLM family (previously branded "Doubao-Coder"). Three released variants: Base (32K), Instruct (32K), and Reasoning (64K, RL-trained). The technical contribution is "LLMs can effectively curate code training data by themselves" — a model-centric data-curation pipeline that beats rule-based filters and produces SOTA results among 8B open-source code models on generation, completion, editing, reasoning, and SWE tasks.

Successor in branding (and pretraining recipe) to the closed Doubao Seed Code flagship. MIT license.
