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 | |

Output Format

{
  "images": [
    {
      "url": "https://fal.media/files/...",
      "content_type": "image/jpeg",
      "width": 1024,
      "height": 1024
    }
  ],
  "seed": 12345,
  "has_nsfw_concepts": [false]
}

Tips

• Real-time models use fewer inference steps — prompts should be clear and concise
• Use --seed to 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
