FLUX.2 Flex

Provider: Black Forest Labs
OpenRouter ID: black-forest-labs/flux.2-flex

Capabilities

  • Text rendering: Excellent — best in class for complex typography and fine detail rendering
  • Image input: Yes — multi-reference editing in a unified architecture. Can pass multiple reference images in a single request.
  • Sizes: Flexible aspect ratios, megapixel-based pricing
  • Privacy: Does not use submissions for model training. Retains prompts for 30 days only.

Pricing

$0.06 per megapixel (input + output combined)

A standard 1024×1024 image ≈ 1MP = ~$0.06. A 1920×1080 image ≈ 2MP = ~$0.12.

Best For

  • Typography-driven creatives where the headline IS the visual
  • Ads requiring complex text layout (multiple lines, mixed sizes)
  • Multi-reference compositions (logo + product + background reference in one request)
  • Fine detail work

Notes

  • The megapixel pricing model rewards smaller output sizes — use 1K for drafts, scale up for finals
  • Multi-reference input is a unique strength — pass logo, product photo, and style reference simultaneously
