BAGEL

BAGEL by ByteDance-Seed is an open-source unified multimodal AI model released under the Apache 2.0 license, making it freely available to developers, researchers, and organizations who want powerful AI capabilities without the lock-in of proprietary systems. Built with a natively multimodal architecture, BAGEL handles advanced image and text understanding, generation, editing, and navigation with precision and photorealistic quality — offering capabilities comparable to leading proprietary models like GPT-4o and Gemini 2.0. Because it's fully open-source, BAGEL can be fine-tuned on your own data, distilled for efficiency, and deployed on your infrastructure — giving you complete control and flexibility. For teams building products that need a capable, trustworthy, and customizable multimodal foundation, BAGEL is the open-source option that doesn't compromise on performance.
