      <h2>Midjourney V8.1 Support</h2>

      <ul>
        <li><strong>V8.1 Model</strong>: Add <code>--v 8.1</code> to your prompt to use Midjourney's latest alpha model — SD (1024) by default with \~40% faster generation than V8 HD</li>
        <li><strong>Native 2K via <code>--hd</code></strong>: add <code>--hd</code> for 2048×2048 output, billed at 1.5× (120 credits) vs 1× (80) for SD</li>
        <li><strong>Image prompts and image weights restored</strong>: V8.1 supports image URLs in prompts and the <code>--iw</code> parameter for image weighting</li>
        <li><strong>Prompt Shortener</strong>: Prompts that exceed length limits are automatically shortened by Midjourney</li>
        <li><strong>Improved Describe</strong>: V8.1 produces longer, more detailed prompt descriptions</li>
        <li><strong>Subscription gate</strong>: V8.1 requires a Pro (Developer) subscription or higher, same as V8</li>
        <li><strong>Removed in V8.1</strong>: <code>--q</code> / <code>--quality</code>, <code>--cref</code> / <code>--cw</code>, <code>--oref</code> / <code>--ow</code>, and <code>--no</code> (negative prompt) are no longer supported. Requests containing these flags will be rejected with a clear error</li>
        <li><strong>V8.0 deprecation</strong>: Midjourney plans to sunset V8.0 approximately 2 weeks after V8.1 stabilizes. Migrate <code>--v 8</code> prompts to <code>--v 8.1</code> to avoid disruption</li>
        <li><strong>Same endpoints</strong>: V8.1 uses the existing <code>/v1/diffusion</code>, <code>/v1/variation</code>, <code>/v1/reroll</code>, <code>/v1/remix</code>, <code>/v1/blend</code>, and <code>/v1/video-diffusion</code> endpoints — no integration changes required</li>

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