Media Creation

When to use

• Generate or edit images.
• Generate or edit videos.
• Generate audio or speech.
• Generate or transform 3D assets.

Workflow

1. Prefer the direct Media AI tools when the distribution exposes them: search_media_models, estimate_media_cost, and run_media_model. If they are absent, use a provider the user has configured or explain what configuration is required.
2. Choose the endpoint and schema.
   • For image generation, default to GPT Image 2 unless the user needs cheaper drafts, a specialized style model, or a non-OpenAI model: openai/gpt-image-2.
   • For image editing, default to GPT Image 2 unless a specialist model is clearly better: openai/gpt-image-2/edit.
   • Use search_media_models when the endpoint or required fields are uncertain.
3. Estimate before spending.
   • Call estimate_media_cost for the chosen endpoint and output count before run_media_model.
   • Tell the user the expected provider cost and any distribution-specific balance charge when both are available.
4. Check balance when cost can climb.
   • For video, 3D, multi-output, high-quality image batches, or budget-sensitive work, inspect the configured provider's limits or balance when that capability is exposed.
   • Mention when retries could compound the cost quickly.
5. Run through the configured tool or provider.
   • Never embed provider credentials in prompts, source files, or generated artifacts.
   • A distribution-provided run_media_model may upload local inputs and charge a hosted balance; describe that behavior before using it.
6. Do not add a hard approval gate on your own.
   • Follow the approval policy of the active runtime and provider.
   • Make the price clear before spending and ask when the active policy requires confirmation.
7. Save outputs into the workspace unless the user explicitly wants remote-only results.
8. If these instructions are already loaded in context, do not spend a shell turn re-reading this SKILL.md from disk.

GPT Image 2

• Use openai/gpt-image-2 for text-to-image work that benefits from high quality, fine typography, product scenes, UI mockups, signage, posters, or detailed realistic images.
• Use openai/gpt-image-2/edit for edits such as replacing objects, changing clothing, cleaning backgrounds, relighting, compositing references, or preserving identity/layout while changing a specific element.
• fal describes GPT Image 2 as OpenAI's latest image model, with text-to-image support for detailed images and fine typography, and edit support for fine-grained changes to images.
• GPT Image 2 supports streaming, commercial use, flexible resolutions up to 4K, and multiple output qualities.
• Text-to-image core input:

{
  "prompt": "Describe the scene, subject, important details, use case, and constraints.",
  "image_size": "landscape_4_3",
  "quality": "high",
  "num_images": 1,
  "output_format": "png"
}

• Edit core input:

{
  "prompt": "Change: exactly what changes. Preserve: identity, pose, lighting, framing, background, geometry, text, and layout. Constraints: no extra objects, no redesign, no watermark.",
  "image_urls": ["./source.png"],
  "image_size": "auto",
  "quality": "high",
  "num_images": 1,
  "output_format": "png"
}

• For masks, add mask_url when the edit should be constrained to a region.
• For multiple references, label the roles in the prompt, for example: "Image 1 is the base scene to preserve. Image 2 is the jacket reference."
• For text inside images, specify exact copy, placement, typography, and constraints such as "Render the text verbatim", "No extra words", and "No duplicate text."
• For edits, keep the prompt narrow: one sentence for what changes, one for what stays locked, and one for physical realism.

Current model examples

• Image examples on fal pages as of April 24, 2026:
• GPT Image 2 text-to-image: openai/gpt-image-2; good default for premium image generation, typography, and realistic detailed scenes.
• GPT Image 2 edit: openai/gpt-image-2/edit; good default for high-quality image edits with clear preserve/change constraints.
• FLUX Kontext Pro: about $0.04/image
• Nano Banana 2: about $0.08/image at 1K
• Nano Banana Pro: about $0.15/image
• Video examples on fal pages as of April 21, 2026:
• Hailuo 02 Standard: about $0.045/second
• Kling 2.5 Turbo Pro: about $0.07/second
• Seedance 2.0 Fast: about $0.2419/second
• Veo 3.1: from about $0.10-$0.20/second on fast/standard 720p/1080p tiers, with higher-cost variants for audio or 4K
• 3D examples on fal pages as of April 21, 2026:
• SAM 3D Objects: about $0.02/generation
• Hunyuan3D v2: about $0.16/generation
• Tripo3D v2.5 image-to-3d: about $0.20-$0.40/generation
• Hunyuan 3D v3.1 Rapid / Pro: about $0.225 / $0.375 plus add-ons

Decision rules

• If the user names a model, still estimate the cost before running it.
• If the user does not name a model, search for candidates and pick one based on quality, latency, editability, and price.
• For image generation or image editing where quality matters more than the cheapest possible draft, start with GPT Image 2.
• For quick ideation, bias toward cheaper image or fast video models.
• For text-heavy graphics, precise editing, or high prompt adherence, favor reasoning-heavy image models after warning about higher cost.
• For long clips, high resolution, audio, or multiple variations, assume the estimate can climb quickly and say so explicitly.
