​
Midjourney V8.1 Support

  • V8.1 Model: Add —v 8.1 to your prompt to use Midjourney’s latest alpha model — HD is now the default output, with ~40% faster generation than V8 HD
  • HD by default, no premium: V8.1 produces native 2K images at the same cost as V8 SD (1x credits). The 4x premium that applied to V8 —hd does not apply to V8.1
  • Image prompts and image weights restored: V8.1 supports image URLs in prompts and the —iw parameter for image weighting
  • Prompt Shortener: Prompts that exceed length limits are automatically shortened by Midjourney
  • Improved Describe: V8.1 produces longer, more detailed prompt descriptions
  • Subscription gate: V8.1 requires a Pro (Developer) subscription or higher, same as V8
  • Removed in V8.1: —q / —quality, —cref / —cw, —oref / —ow, and —no (negative prompt) are no longer supported. Requests containing these flags will be rejected with a clear error
  • V8.0 deprecation: Midjourney plans to sunset V8.0 approximately 2 weeks after V8.1 stabilizes. Migrate —v 8 prompts to —v 8.1 to avoid disruption
  • Same endpoints: V8.1 uses the existing /v1/diffusion, /v1/variation, /v1/reroll, /v1/remix, /v1/blend, and /v1/video-diffusion endpoints — no integration changes required

Midjourney V8 Support

  • V8 Model: Add —v 8 to your prompt to use Midjourney’s latest model — ~5x faster generation, native 2K HD resolution, dramatically improved text rendering, and accurate anatomy
  • Native 2K with —hd: V8 renders natively at 2K resolution. No upscale step needed. Use —hd for high-resolution output (4x credit cost)
  • New —oref parameter: Omni Reference replaces —cref in V8, handling both person likeness and object form in a single parameter
  • Enhanced coherence with —q 4: New quality mode for complex scenes with many elements (4x credit cost)
  • V8 Blend: Blend endpoint now uses V8 natively for improved results
  • Full follow-up support: Variation, reroll, remix, and animate all work on V8-generated images
  • Backward compatible: Your existing V7 personalization profiles and style references work in V8

Improvements

​
Response structure enhancements

  • 4-grid image display: Enhanced response structure to support 4-grid image display for /imagine tasks, providing better visualization of generated image variations

​
Service optimization

  • Temporary API endpoint suspension: The following endpoints are temporarily paused:
    • /upload-paint
    • /retexture
    • /remove-background
    • /enhance

    These endpoints will be restored promptly after optimization is complete.
