Side-by-side comparison — features, pricing, pros and cons
GPT Image is OpenAIs native image generation in GPT-4o, launched March 2025. Creates and edits images directly in ChatGPT with accurate text rendering, multi-turn consistency, and support for up to 4096x4096 resolution via gpt-image-1 API. Free for all ChatGPT users.
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.
