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

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
