Dola Seed 2.0 Lite is the balanced tier of ByteDance's Dola Seed 2.0 family on BytePlus ModelArk.
- BytePlus describes its newest release as the first omnimodal understanding model in the Dola family, natively unifying video, image, audio, and text understanding with upgraded agent, coding, and GUI capabilities; the prior release was billed as a cost-efficient, high-throughput enterprise upgrade over seed-1-8 with strong long-context understanding and reliable structured outputs.
- It offers a 256K context window with up to 128K output including chain-of-thought.
- Synthorai brokers it through an OpenAI-compatible chat API.
