fal-realtime
Real-time and streaming image generation using fal.ai's fastest models. Results in under 1 second — ideal for interactive applications, live previews, and rapid iteration.
Scripts
| Script | Purpose |
|---|---|
realtime.sh | Generate images in real-time (sub-second) |
Usage
Quick Real-Time Generation
./scripts/realtime.sh --prompt "A cute cat wearing a top hat"With LoRA
./scripts/realtime.sh --prompt "A portrait in sks style" --lora-url "https://example.com/lora.safetensors"Multiple Rapid Iterations
./scripts/realtime.sh --prompt "Abstract art with flowing colors, version 1"
./scripts/realtime.sh --prompt "Abstract art with flowing colors, version 2, more vibrant"
./scripts/realtime.sh --prompt "Abstract art with flowing colors, version 3, darker tones"Arguments
| Argument | Description | Required |
|---|---|---|
--prompt / -p | Image description | Yes |
--model / -m | Model endpoint | No (default: fal-ai/flux-2/klein/realtime) |
--size | square, landscape, portrait | No (default: square) |
--seed | Random seed for reproducibility | No |
--lora-url | URL to LoRA weights | No |
--lora-scale | LoRA influence (0.0-1.0, default: 1.0) | No |
--num-images | Number of images (default: 1) | No |
Finding Models
To discover the best and latest real-time generation models, use the search API:
# Search for real-time / fast image generation models
bash /mnt/skills/user/fal-generate/scripts/search-models.sh --query "realtime"
bash /mnt/skills/user/fal-generate/scripts/search-models.sh --query "fast image"
bash /mnt/skills/user/fal-generate/scripts/search-models.sh --category "text-to-image"Or use the search_models MCP tool with keywords like "realtime", "fast", "schnell", "turbo".
When to Use Real-Time vs Standard Generation
| Use Case | Use Real-Time | Use Standard |
|---|---|---|
| Rapid prototyping / iteration | Yes | |
| Interactive apps / live preview | Yes | |
| Final high-quality output | Yes (FLUX Dev, Nano Banana Pro) | |
| Professional / commercial work | Yes (FLUX Pro Ultra) | |
| Exploring prompt ideas quickly | Yes | |
| Batch generation with variations | Yes |

}Tips
- Real-time models use fewer inference steps — prompts should be clear and concise
- Use
--seedto lock in a good composition, then iterate on the prompt - LoRA support works with FLUX Klein Realtime — great for style-locked fast iteration
- These models use the synchronous API (no queue), so results are instant
