Comprehensive side-by-side LLM comparison
Seed 1.5-VL supports multimodal inputs. Both models have their strengths depending on your specific coding needs.
xAI
Grok 3 mini, released by xAI alongside Grok 3 in February 2025, is a compact reasoning model from the Grok 3 family featuring RL-enhanced Think mode for extended chain-of-thought processing. It features a 131K token context window and targets STEM tasks, mathematics, and coding applications where cost-efficient reasoning with configurable depth is required.
ByteDance
Seed1.5-VL, released by ByteDance Seed on May 15, 2025, is a vision-language foundation model composed of a 532M-parameter vision encoder and a Mixture-of-Experts language model with 20 billion active parameters. It was pretrained on over 3 trillion multimodal tokens and achieved state-of-the-art performance on 38 out of 60 public VLM benchmarks at release. Seed1.5-VL targets complex visual reasoning, OCR, video comprehension, 3D spatial understanding, and multimodal agentic tasks.
