6 words

A social platform where a question receives an AI image cover and the community replies in exactly 6 words. Key innovation: Prompt-on-Prompt technique, where AI first translates an abstract query into a precise visual descriptor before it enters the diffusion model. Fully asynchronous pipeline via Symfony Messenger, credits, automatic categorization, typo-tolerant search, and a custom auto-moderation system.

Prompt-on-Prompt Pipeline Two-phase AI transformation: GPT-4 first translates an abstract question into a precise visual descriptor, DALL-E 3 generates a cover at 1792×1024.
Fully Asynchronous AI Pipeline 7 specialized Symfony Messenger handlers — images, answers, categories, nicknames, emails. UI never waits for AI.
  • OpenAI GPT-4o + DALL-E 3
  • Asynchronous Symfony Messenger + Scheduler
  • Prompt-on-Prompt (two-phase image generation)
  • Loupe — typo-tolerant full-text search (PHP-native)
  • Weighted Report Score with dynamic reporterTrust
  • Custom Imagick composite engine (brick grid + sigmoid blend)

        $prompt = $this->promptGenerator->generateImagePrompt(
            $question->getQuestion()
        );

        // Phase 2: DALL-E 3 generates the actual image at 1792×1024
        foreach ($this->generator->generateImage($prompt, 1792, 1024, 1) as $resource) {
            $this->imageService->createImage($resource, $question);
