Since ChatGPT launched in late 2022, image generation was a paid-only feature. As of this week, OpenAI expanded the free tier to include a limited daily allowance of DALL-E generations — removing the last paywall between a first-time creator and a complete AI content toolkit.
Here's what you get on the free plan, how the quality compares, and the specific use cases where free-tier ChatGPT images save the most time for affiliate content creators.
What the free tier includes
ChatGPT free plan: 2 DALL-E image generations per day. Each generation can produce up to 4 variants from a single prompt. Images are generated at up to 1792×1024px — wide enough for blog hero images and YouTube thumbnails. Commercial rights are included with all generations, both free and paid.
ChatGPT Plus ($20/month): 50 generations per day at higher quality settings, including the DALL-E HD mode which adds more fine detail and reduces artifacts. For creators producing daily content, Plus is worth the upgrade. For someone just starting out publishing 3–4 pieces of content per week, 2 free generations per day is workable.
The generations don't roll over — unused daily allowance resets at midnight. Use your two per day strategically.
How it compares to other free image tools
There are now several free AI image options. Here's the honest comparison:
ChatGPT DALL-E 3 free — best for prompt accuracy. Follows complex text instructions reliably, integrates context from your chat conversation, good for content-specific images (showing a specific tool on a laptop screen). 2 generations/day free. Quality is excellent but slightly softer than Midjourney.
Adobe Firefly free tier — 25 monthly generative credits. Excellent for images requiring commercial safety — Firefly is trained only on licensed Adobe Stock content, so there are no copyright edge cases. Best for product mockups and lifestyle imagery.
Ideogram free tier — 10 free generations/day, excellent at generating images with accurate readable text. Best for: thumbnail overlays, infographic headers, any image that needs text embedded in it. ChatGPT struggles with in-image text; Ideogram does it well.
Canva AI free tier — 5 generations/month within Canva's design environment. Best when you need the image integrated directly into a designed layout rather than as a standalone file.
The practical workflow: use Ideogram for any image needing embedded text, ChatGPT DALL-E for concept-specific images that need precise prompt following, Canva for branded layouts.
The 3 use cases that matter for affiliate creators
1. Blog hero images. Every review post needs a header image. Prompt: "A dark-themed website interface on a MacBook Pro screen showing [tool name], isolated on a dark studio background, professional product photography lighting, 16:9 aspect ratio." This produces a generic but credible-looking software screenshot hero that doesn't infringe any tool's actual UI copyright because it's AI-generated.
2. YouTube thumbnails. YouTube thumbnails perform best with high contrast, a face (or implied face/reaction), and minimal text. For faceless channels, the "face" element is replaced by a visual concept. Prompt: "A bold, high-contrast thumbnail image showing [concept] — dramatic lighting, red and yellow accent colours, no text, cinematic style." Use Ideogram if you want "FREE" or "2026" text overlaid directly in the generated image.
3. Social media graphics. Pinterest pins (1000×1500px vertical), Instagram carousels, and LinkedIn visuals all need consistent imagery. Prompt batch your 2 daily generations around a theme: Monday = two blog header variants, Tuesday = two Pinterest pin backgrounds, Wednesday = two comparison/infographic backgrounds.
Prompt structures that work
ChatGPT DALL-E follows conversational context, which means you can refine in-chat. Start broad, then narrow:
Prompt 1: "A clean product screenshot of an AI writing tool on a dark background, no actual UI visible, just the laptop and glow from the screen."
Follow-up: "Same image but make the background deep navy blue, add a subtle purple gradient glow from the screen, and add a faint keyboard reflection."
This iterative prompting is unique to ChatGPT — other tools don't maintain context between generations. Use it to get precise results without needing long single prompts.

How many free image generations does ChatGPT give per day?
The ChatGPT free tier includes 2 DALL-E image generations per day (up to 4 variants per generation). ChatGPT Plus ($20/month) gives 50 per day at higher quality. Daily allowance resets at midnight and doesn't roll over.
How does ChatGPT image generation compare to Midjourney?
Midjourney produces more aesthetically polished, artistically styled images. ChatGPT DALL-E 3 follows complex text prompts more accurately and maintains context across a conversation for iterative refinement. For concept-specific images (specific tools, layouts, concepts), ChatGPT is more controllable. For pure aesthetic quality, Midjourney is still ahead.
Can I use ChatGPT-generated images commercially?
Yes. OpenAI's terms grant full commercial rights to all DALL-E generated images, including on the free plan. Use them for blog thumbnails, social media, and affiliate content without additional licensing.
What are the best prompts for affiliate marketing images?
For software reviews: "A dark-themed laptop screen showing [tool], studio lighting, no text." For educational thumbnails: "Minimalist infographic, dark background, [concept] in 3 numbered steps, white and accent colours." For comparison content: "Split image — [before state] left, [after state] right, same lighting and framing."
