Troubleshooting GLMImage: Complete Problem-Solving Guide
GLMImage troubleshooting encompasses diagnosing and resolving common issues with AI image generation, including text rendering problems, quality concerns, generation errors, account issues, and technical difficulties. Working through the checks below resolves most issues without needing support.
Key Takeaways
-
Most GLMImage issues stem from prompt problems—most "poor results" come down to the prompt: keep text short, specify placement clearly, and add quality keywords.
-
Text rendering issues have specific solutions: reduce text length to 3-5 words English (5-8 Chinese), specify exact placement, describe typography, and use image-to-image for refinement (Text Rendering Guide, 2026).
-
Technical problems are rare but have quick fixes: clear browser cache, disable VPN/proxy, check internet connection, and ensure compatible browser (Chrome, Edge, Firefox) resolves most issues (Technical Support, 2026).
Common Issues and Solutions
Issue 1: Text Rendering Problems
Problem: Text is garbled or misspelled
| Cause | Solution |
|---|---|
| Text too long | Shorten to 3-5 words (EN) or 5-8 characters (ZH) |
| Unclear placement | Specify exact location: "text centered at top" |
| No font description | Add: "bold sans-serif font" |
| Conflicting instructions | Remove contradictory elements |
Fixed Prompt Example:
BEFORE: "Poster with text SUMMER CLEARANCE SALE EVERYTHING MUST GO NOW"
AFTER: "Poster with text 'SUMMER SALE' centered at top, bold sans-serif font, highly legible"
Problem: Chinese text rendering poorly
| Cause | Solution |
|---|---|
| Using wrong tool | Use GLMImage for Chinese text rendering |
| Text too long | Keep Chinese text under 8 characters |
| No placement specified | Add: "Chinese text [placement] with equal prominence" |
| Mixed too many languages | Maximum 2 languages per image |
Best Practice for Chinese Text:
Conference poster with bilingual text, English "GLOBAL SUMMIT" at top,
Chinese "全球峰会" below with equal prominence, clean bilingual typography,
highly legible for both languages
Problem: Text not prominent enough
| Solution | Prompt Addition |
|---|---|
| Make larger | "text prominently displayed" |
| Better placement | "text at top" or "text centered" |
| Add contrast | "white text on dark background" |
| Specify size | "large text" or "bold text" |
Issue 2: Image Quality Problems
Problem: Images look blurry or low quality
| Solution | Prompt Addition |
|---|---|
| Add quality keywords | "sharp focus, highly detailed, 8K" |
| Check resolution setting | Ensure 1024px+ selected |
| Specify photography type | "professional photography" |
| Add technical details | "shot on 85mm lens, f/1.4" |
Before/After Example:
BEFORE: "Portrait of woman"
AFTER: "Professional portrait of woman, sharp focus, highly detailed, 8K quality,
shot on 85mm f/1.4 lens, studio lighting"
Problem: Colors look wrong or oversaturated
| Cause | Solution |
|---|---|
| No color specification | Add specific colors: "navy blue and white" |
| Conflicting color instructions | Choose one color scheme |
| Overly vibrant default | Add: "natural colors, muted tones" |
| AI interpretation drift | Use image-to-image with color reference |
Color Control Prompt:
Product photography with accurate colors, navy blue and white color scheme,
natural lighting, realistic color representation, professional product photo
Problem: Same prompt gives different results
| Cause | Solution |
|---|---|
| Random seed each time | Use fixed seed value |
| Minor wording differences | Keep prompts identical |
| Model temperature | Normal behavior—seed fixes this |
Using Seeds for Consistency:
- Generate image you like
- Note the seed value from generation details
- Reuse seed with prompt variations
- Results will maintain consistency
Issue 3: Generation Not Starting
Problem: Generation stuck or very slow
| Cause | Solution |
|---|---|
| High server load | Wait a few minutes, try again |
| Free tier queue | Upgrade for priority queue (Pro tier) |
| Large resolution | Reduce from 2048px to 1024px |
| Internet connection | Check connection speed |
Check Your Status:
- Free tier: Standard queue (may wait during peak times)
- Basic tier: Standard queue
- Pro tier: Priority queue (faster generation)
- Enterprise: Priority queue with dedicated resources
Problem: "Generation failed" error
| Cause | Solution |
|---|---|
| Violation detected | Review prompt for prohibited content |
| Technical glitch | Try again with same prompt |
| Account issue | Verify subscription is active |
| Server maintenance | Check status page for outages |
Issue 4: Account and Billing Issues
Problem: Can't generate more images
| Cause | Solution |
|---|---|
| Reached monthly limit | Wait for renewal or upgrade tier |
| Subscription expired | Renew subscription |
| Payment failed | Update payment method |
Monthly Limits by Tier:
- Free Trial: 2 images total
- Basic: 200 images/month
- Pro: 1,000 images/month
- Enterprise: Custom limits
Problem: Need more images this month
| Solution | How |
|---|---|
| Upgrade tier | Immediate effect, prorated billing |
| Enterprise | Custom packages for overages |
| Wait for renewal | Monthly reset on billing date |
Issue 5: Technical Issues
Problem: Images won't download
| Cause | Solution |
|---|---|
| Browser issue | Try different browser (Chrome, Edge, Firefox) |
| Popup blocker | Allow downloads from glmimage.app |
| Internet connection | Check connection stability |
| Large file size | Wait for complete download |
Problem: Interface not loading
| Cause | Solution |
|---|---|
| Browser cache | Clear cache and cookies |
| VPN/Proxy | Disable and try direct connection |
| Outdated browser | Update to latest version |
| Ad blocker | Disable for glmimage.com |
| JavaScript | Ensure JavaScript is enabled |
Browser Compatibility:
| Browser | Support | Notes |
|---|---|---|
| Chrome | ✓ Full | Recommended |
| Edge | ✓ Full | Recommended |
| Firefox | ✓ Full | Good |
| Safari | ✓ Full | May have quirks |
| Opera | ⚠️ Partial | Use Chrome/Edge instead |
Prompt-Specific Troubleshooting
Problem: Results don't match prompt
| Issue | Solution |
|---|---|
| Too vague | Add specific details |
| Too many elements | Simplify to 3-5 key elements |
| Conflicting instructions | Remove contradictions |
| Complex sentence structure | Use simple, clear language |
Prompt Improvement Process:
Original → Simplify → Add specifics → Test → Refine
Problem: Style not matching expectations
| Issue | Solution |
|---|---|
| No style specified | Add: "photorealistic," "digital art," etc. |
| Conflicting styles | Choose one primary style |
| Generic style | Use specific reference: "in the style of [artist/work]" |
Style Keywords to Use:
| Desired Style | Prompt Keywords |
|---|---|
| Photorealistic | "photorealistic, professional photography, 8K" |
| Digital art | "digital art, illustration, clean lines" |
| Oil painting | "oil painting style, brushstrokes visible" |
| Cinematic | "cinematic, film still, dramatic lighting" |
| Minimalist | "minimalist, clean, simple composition" |
Advanced Troubleshooting
Issue: Image-to-Image Not Working
Problem: Image-to-image gives unexpected results
| Cause | Solution |
|---|---|
| Strength too high | Reduce to 0.5-0.7 |
| Strength too low | Increase to 0.6-0.8 |
| Conflicting prompt | Align prompt with reference image |
| Poor reference image | Use clearer, higher-quality reference |
Strength Setting Guide:
| Strength | Use Case |
|---|---|
| 0.1-0.3 | Minor adjustments, color tweaks |
| 0.4-0.5 | Style changes, minor element additions |
| 0.6-0.7 | Significant changes, major style shifts |
| 0.8-0.9 | Complete transformation |
Issue: API Problems
Problem: API requests failing
| Error | Solution |
|---|---|
| 401 Unauthorized | Check API key validity |
| 429 Rate limited | Reduce request frequency |
| 400 Bad request | Verify request parameters |
| 500 Server error | Retry with exponential backoff |
API Best Practices:
- Implement exponential backoff for retries
- Cache successful responses
- Monitor rate limit headers
- Use batch requests when possible
