Frequently Asked Questions

Is ChatGPT image generation completely free now?

Yes, as of April 2025, OpenAI has made ChatGPT 4o image generation available to all users, including those on the free tier. However, free users face daily generation limits and potential queue times during peak usage.

What are the limitations of free GPT image generators?

Free services typically impose daily generation limits (15-50 images), lower resolution outputs, possible watermarking, longer queue times, and often restrict commercial usage rights.

Is laozhang.ai an official OpenAI partner?

laozhang.ai is an independent service provider offering access to various AI APIs, including OpenAI’s models, at more affordable rates. It acts as an intermediary service that manages API access and billing.

How does laozhang.ai offer lower prices than direct API access?

laozhang.ai optimizes API usage through batch processing, resource pooling, and efficient token management, allowing them to pass the savings to users while maintaining service quality.

Can I use images generated through these tools commercially?

What’s the difference between DALL-E and GPT-4o image generation?

DALL-E is OpenAI’s dedicated image generation model, while GPT-4o is a multimodal model with integrated image generation capabilities. GPT-4o often produces more contextually aware images and can understand more nuanced prompts.

Conclusion: Making the Right Choice for Your Needs

The democratization of AI image generation has created a spectrum of options for different user needs:

• Casual Users: Free options like ChatGPT’s basic access or Microsoft Designer provide sufficient capabilities for occasional use.
• Regular Creators: For those needing reliable, higher-quality images without strict limits, laozhang.ai offers the most cost-effective solution with its discounted API access.
