Comprehensive side-by-side LLM comparison
. Both models have their strengths depending on your specific coding needs.
xAI
Grok 2, released by xAI in August 2024, is a large language model with 131K token context window and native image understanding, developed with access to real-time information from the X platform. It features multimodal input capabilities and improved reasoning over its predecessor. Grok 2 targets conversational assistants, image analysis, and real-time information retrieval tasks via the xAI API.
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.
