What they are

Stable Diffusion

Stable Diffusion is Stability AI's family of open-weight text-to-image models, covering everything from the widely adopted SD 1.5 and SDXL to the current SD 3.5 series. Developers access it via a credit-based API, while creators with capable hardware can run it locally for free under the Community License. It spans image generation, editing, upscaling, style transfer, 3D asset creation, and audio generation. The ecosystem of community fine-tunes, LoRAs, and third-party UIs is unmatched, but that depth comes with a real learning curve.

Windsurf

Windsurf is an AI-native IDE centered on Cascade, an agentic coding interface that reads your entire codebase and makes coordinated edits across multiple files from a single prompt. It ships proprietary models (SWE-1, SWE-1.5) alongside access to Claude, GPT, and Gemini, plus browser previews, deploys, and Devin cloud sessions for background development. Individual developers and teams use it as a full Cursor alternative. Note that the product is transitioning to the Devin Desktop name under Cognition, which may affect branding consistency going forward.
