Side-by-side comparison — features, pricing, pros and cons
OpenAI's image generation capability, now integrated natively into ChatGPT as "GPT Image" and no longer available as a standalone product. Powered by the DALL-E 3 model, it excels at following detailed text prompts and renders accurate text within images — a significant advantage over Midjourney. Accessible via ChatGPT Plus or the OpenAI Images API.
Open-source latent diffusion model for local image generation, now at SD3.5 with improved composition and text rendering. Self-hostable on consumer GPUs (8GB VRAM minimum for SD3.5 base), with an extensive ecosystem of fine-tuned models on Civitai. Stability AI underwent restructuring in 2025 after funding challenges but the open-source ecosystem remains active.
