EVE Series: Encoder-Free VLMs from BAAI

• 2024/05: Unveiling Encoder-Free Vision-Language Models (NeurIPS 2024, spotlight)

• 2024/11: EVEv2: Improved Baselines for Encoder-Free Vision-Language Models (ICCV 2025, highlight)

💡 Motivation

• Can we remove vision encoder from VLMs?

• How to transfer an LLM to an encoder-free VLM efficiently and stably?

• How to bridge the performance gap between encoder-free and encoder-based VLMs?

📜 News

💡 Highlights

• 🔥 Superior Capability: An originated encoder-free LVLM with arbitrary image aspect ratio, outperforming the counterparts and approaching existing modular encoder-based LVLMs.

• 🔥 Data Efficiency: Filter and recaption solely <100M publicly avaliable data from OpenImages, SAM, LAION, Datacomp for pre-training.

• 🔥 Pioneering Route: We attempt to provide an efficient, transparent, and practical training strategy and procedure for developing a pure decoder-only architecture across modalities.
