Nano Banana exploded onto the scene in late 2025 and quickly overtook the competition. Why? Because it offers the "Raw Creativity" that other models filtered out. It allows for stylization that feels genuinely human-made, not "AI-generated."
- ✓ Style Control: You can upload a "Mood Board" and it mimics the aesthetic perfectly.
- ✓ No Censorship: Less restrictive on artistic nudity or violence compared to DALL-E.
- ✓ Banana Engine: Their proprietary rendering engine handles text better than anyone.
- ✕ Server Load: Due to popularity, generation can sometimes lag during peak hours.
GPT-1.5 isn't just an image generator; it's a multimodal intelligence. Unlike other tools where you have to memorize complex prompts, you can simply talk to GPT-1.5.
- ✓ Conversational Editing: Edit images by typing changes (e.g., "Remove the tree").
- ✓ Text Accuracy: Finally spells words correctly on signs and logos.
- ✕ "Smooth" Look: Images can sometimes look too polished and digital.
- ✕ Strict Safety: You cannot generate public figures or copyrighted characters.
If your goal is to fool people into thinking an image is a real photograph, Midjourney v7 is your tool. The lighting engine in v7 is spectacular. It captures skin pores, dust particles in the air, and film grain in a way that Nano Banana and GPT-1.5 still struggle to match.
- ✓ Cinematic Quality: Looks like a movie still straight out of the box.
- ✓ Community: The "Explore" feed is a goldmine for prompt inspiration.
- ✕ Discord Legacy: Many features are still hidden in Discord commands.
