Comprehensive side-by-side LLM comparison
Doubao 1.5 Vision Pro supports multimodal inputs. Both models have their strengths depending on your specific coding needs.
ByteDance
Doubao 1.5 Vision Pro, released by ByteDance via Volcano Engine on January 22, 2025, is a multimodal large language model from the Doubao 1.5 family with comprehensive upgrades to visual reasoning, OCR, and fine-grained image understanding. Built on a large-scale sparse MoE architecture, it targets vision-intensive workflows including document analysis, chart interpretation, and visual question answering.
NVIDIA
Llama-3.1-Nemotron-Ultra-253B-v1 is a 253-billion-parameter model from NVIDIA, derived from Meta's Llama 3.1 405B using neural architecture search (NAS) compression combined with NVIDIA's Nemotron post-training pipeline, which recovers and exceeds the base model's capability after structural compression. Released in April 2025, it supports toggling between a standard instruction mode and an extended reasoning mode via system prompt, allowing the same model to handle both rapid responses and deliberate chain-of-thought tasks. It is the flagship of the Nemotron family, available open-weight on HuggingFace and through NVIDIA NIM for enterprise inference.
