A feature-by-feature comparison of Leonardo.Ai and FLUX across 7 capability categories.
Modalities — Leonardo.Ai Wins
| Feature | Leonardo.Ai | FLUX |
|---|---|---|
Text Input | Yes. Text prompting is the primary interface. | Yes, requires free plan. Text prompts drive FLUX text-to-image on the BFL API and open-weight inference. |
Image Upload / Vision | Yes. Image-to-image, inpainting and reference-guided generation. | Yes, requires plus plan. FLUX.1 Kontext and Fill/Expand endpoints take images for editing. Hosted API is pay-as-you-go. |
Image Generation | Yes. Core product, with a library of community and custom models. | Yes, requires free plan. Core product: FLUX.1 [schnell]/[dev] locally, plus FLUX.2 Pro/Max/Flex/Klein via API. |
Voice Mode | No. No voice interface. | No. Not a conversational voice product. Docs mention synchronized audio on some FLUX 3 video paths; that is generated soundtrack, not a voice loop. |
Video Understanding | No. Generates short video clips but does not analyse existing video. | No. FLUX 3 docs talk about generating video, not Q&A over uploaded video. |
Video Generation | Yes, requires plus plan. Motion/video clips from generated stills in Leonardo. | No. Not a video generation product. |
File Upload (PDF, DOCX) | No. No document ingestion. | No. Inputs are prompts and images, not PDF/DOCX. |
Code Execution | No. Not a code tool. | No. You run inference code; the model does not execute your Python. |
Audio Input | No. No audio input. | No. No audio-file input is documented for image endpoints. |
Canvas / Artifact Editor | Yes. Canvas editor for inpainting and outpainting. | Partial. Kontext/Fill/Expand are image editors via API, not a chat canvas. |
Screen Sharing / Computer Use | No. No computer-use capability. | No. No computer-use product. |

|---|---|---|
Persistent Memory | No. No cross-session memory of the user. | No. Each generation is a job. No user memory layer. |
Large Context Window | No. Not a language model, so this does not apply. | No. Not an LLM context-window product. |
Custom Instructions | No. No global instruction setting. | No. No global instruction profile. Fine-tunes/LoRAs are weights, not a system prompt. |
Conversation History | No. Not a chat product, so there is no conversation to configure. | No. Dashboard jobs are not a chat history product. |
