Now it’s TikTok parent ByteDance’s turn for a reasoning AI: enter Seed-Thinking-v1.5!
It achieved an 8.0% higher win rate over DeepSeek R1, suggesting that its strengths generalize beyond just logic or math-heavy challenges.
ByteDance, the Chinese web media giant parent of TikTok, is the latest to join the party with announcement and publication of the technical paper behind Seed-Thinking-v1.5, an upcoming large language model (LLM) designed to advance reasoning performance across both science, tech, math, and engineering (STEM) fields and general-purpose domains. Positioned as a compact yet capable alternative to larger state-of-the-art models, Seed-Thinking-v1.5 achieves competitive benchmark results and introduces innovations in reinforcement learning (RL), training data curation, and AI infrastructure. The fact that Seed-Thinking-v1.5 was trained with mechanisms to adapt reward feedback based on runtime dynamics speaks directly to the challenges of managing heterogeneous data pipelines and maintaining consistency across domains.
