Choosing a Model

Framo runs many AI models. Every one is declared in the model registry (lib/fal-ai/models), and each carries guide metadata — a speed badge (fast/medium/slow), a quality badge (standard/high/ultra), and a bestFor list. That registry is the source of truth for what exists and what each model does. This doc is the routing layer: given a task, which family to reach for. Deeper, model-specific prompting craft lives in the per-family Model docs (Wan is the first — see Wan).

The axes that matter

Pick along four axes, in order:

1. Modality — image, video, 3D, upscale/utility, or training. This narrows the field first.
2. Input mode — text-to-image, image-to-image, multi-reference, or start+end frame. A model only accepts the modes in its compatibleModes.
3. Speed vs quality — fast/high for iteration and drafts; ultra (often medium/slow) for finals, print, and hero shots.
4. Cost — video and 3D scale with duration / resolution; the Generate button always shows the exact credit cost before you commit.

By task

Generate an image from text

• Nano Banana 2 (fast/high) — Google's fast text-to-image with resolution control. A strong default for everyday generation. See Nano Banana.
• FLUX 2 (fast/high) and FLUX Schnell (fast/high) — fast FLUX options for quick drafts and iteration. See FLUX.
• FLUX Ultra (medium/ultra) and FLUX Pro v1.1 (medium/ultra) — reach here for finals: 4× resolution, Raw mode for natural texture, large-format print. See FLUX.
• GPT Image 2 (medium/high) — OpenAI's typography specialist; reach here when legible in-image text and strict prompt adherence matter. See GPT Image.

Edit or composite an existing image (no mask)

• Nano Banana Pro (medium/ultra) — semantic multi-image editing, up to 14 input images, 1K/2K/4K. Best for character consistency and high-res compositing. See Nano Banana.
• Seedream v4 Edit (medium/high) — natural-language editing, up to 10 input images; background replacement, style and material changes. See Seedream.
• Qwen Image Edit (medium/high) — prompt-driven edits that work without a mask. See Qwen.
• GPT Image 2 Edit (medium/high) — fine-grained edits with excellent text rendering, multi-image reference, and native mask support. See GPT Image.

Fill or inpaint a masked region

• FLUX Pro v1 Fill (medium/ultra) — inpainting for masked areas. See FLUX.
• Z-Image Turbo Inpaint (fast/high) — fast masked fill on the 6B turbo core, optionally LoRA-styled. See Z-Image.
• GPT Image 2 Edit (medium/high) — native mask inpainting with strong text rendering. See GPT Image.
• The mask-injection variants (Nano Banana / Nano Banana Pro / Nano Banana 2) apply a semantic edit confined to a drawn selection. See Nano Banana and Image tools.

Animate a still (image-to-video)

• Wan 2.6 (medium/high) — fast previews and multi-shot narrative from a single image (timestamped shot syntax). See Wan.
• Veo 3.1 Lite (medium/high) — Google's high-quality image-to-video with native audio and lip-sync, single start frame. See Veo.
• Kling v3 Standard (medium/high) — balanced; optional end frame and native audio. See Kling.
• Seedance 2 (medium/ultra) — flagship cinematic motion; optional end frame and free synced audio. See Seedance.

Transition or compose video

• Smooth start→end: Kling v3 Standard or Seedance 2 (optional end frame); Veo 3.1 Lite FLF (medium/high) or Wan 2.1 FLF2V (medium/standard) for interpolation that requires both frames.
• From many references: Seedance 2 Reference (medium/ultra) — up to 9 reference images and 3 reference videos.

See Generating Videos and the image-to-video playbook.

Image to 3D model

• Trellis 2 (medium/high) — high-quality 3D from a single image. See Trellis.
• Hyper3D Rodin v2 / v2.5 (slow/ultra) — production-ready models from reference images. See Hyper3D Rodin.
• Hunyuan 3D Pro (slow/ultra) — top-end quality. See Hunyuan 3D.

See the 3D scene editor.

Upscale and utility

• Topaz Upscale (fast/ultra) — premium upscaling.
• Bria Background Remove (fast/high) — commercial-safe background removal.
• Object Removal (fast/high) — erase an object cleanly.
• Qwen Multiple Angles (medium/high) — new camera angles of a subject. See Qwen.

Train a custom model

• FLUX LoRA Fast Training (slow/high) — fast LoRA training for FLUX. See FLUX.
• Z-Image Trainer (medium/high) — train a Z-Image Turbo LoRA. See Z-Image.

See LoRA training and the train-a-LoRA playbook.

Keeping this honest

The model list and the speed/quality/bestFor facts above are mirrored from the registry — re-verify against lib/fal-ai/models when you bump the timestamp. The registry is canonical for parameters, resolutions, durations, and pricing; this doc never restates those numbers. Per-family prompting craft (how to get the most out of each model) lives in Models.
