ERNIE-Image vs HunyuanImage 3.0: 8B Precision vs 80B Behemoth — The Complete Open-Source Text-to-Image Showdown of 2026
Can Baidu's 8B-parameter ERNIE-Image compete with Tencent's 80B-parameter HunyuanImage 3.0? We found the optimal balance between efficiency and scale.
Introduction
The open-source text-to-image landscape in 2026 is undergoing unprecedented divergence. On one side: ERNIE-Image by Baidu, an 8B-parameter model deployable on a single consumer GPU. On the other: HunyuanImage 3.0 by Tencent, boasting 80B MoE parameters and billed as "the largest open-source text-to-image model." These two models represent fundamentally different technical philosophies: efficiency-first vs scale-first.
This comprehensive comparison covers architecture, inference performance, text rendering, multilingual support, hardware requirements, licensing, and ecosystem to help developers, creators, and enterprise decision-makers choose the right model.
I. Architecture Showdown: Single-Stream DiT vs MoE DiT
ERNIE-Image: 8B Single-Stream Diffusion Transformer
ERNIE-Image employs a streamlined single-stream Diffusion Transformer architecture with all 8B parameters activated during inference. The key advantage of this design is simplicity is power — no complex expert routing, deterministic inference paths, and maximum efficiency.
ERNIE-Image Architecture:
├── 8B DiT parameters (fully activated)
├── FLUX.2 VAE (open-source latent space)
├── Prompt Enhancer (Ministral 3B fine-tune)
└── DMD+RL optimization (Turbo variant)
Strengths:
- Deterministic inference paths, no routing overhead
- Single GPU deployment
- Quantization-friendly (GGUF/NVFP4/FP8/INT8 all supported)
- Mature ecosystem (SGLang, ComfyUI, Diffusers)
Weaknesses:
- Parameter ceiling limits model capacity
- Complex scene understanding inferior to larger models
HunyuanImage 3.0: 80B MoE Diffusion Transformer
HunyuanImage 3.0 adopts a Mixture-of-Experts architecture with 80B total parameters, activating only ~13B per token. 64 specialized expert networks collaborate through intelligent routing.
HunyuanImage 3.0 Architecture:
├── 80B total parameters, 64 expert networks
├── ~13B activated parameters/token (MoE routing)
├── Multilingual text encoders (CN/EN optimized)
