ByteDance Seed 2.0 Mini Is Now Available in Puter.js

Puter.js now supports Seed 2.0 Mini, ByteDance's most lightweight and inference-efficient model in the Seed 2.0 family.

What is Seed 2.0 Mini?

Seed 2.0 Mini is the smallest variant in ByteDance's Seed 2.0 series, optimized for low-latency, high-concurrency, and cost-sensitive applications. Despite being the lightweight option, it delivers strong benchmark scores—87.0 on AIME 2025, 1644 on Codeforces, and 67.9 on SWE-Bench Verified.

Key highlights:

• 256K context window with up to 128K output tokens
• Multimodal input supporting text, image, and video
• 4-level reasoning effort system that lets you trade speed for depth depending on task complexity
• High throughput at 1.5M tokens per minute and 30K requests per minute
