# WP Agentic Writer: Recommended Best Flow for Images (Cost-Optimized)
|
||
|
||
## The Challenge You Asked About
|
||
|
||
**Your question:**
|
||
> "After article generation, how do we get image placement with alt by writing agent, then generate recommended images? Need to be cost-efficient with image prompts."
|
||
|
||
**The answer:** Use the **writing agent itself** to analyze placement + generate prompts (tiny cost), then show user a preview before spending on image generation.

## Recommended Best Flow (Option A - SAFEST)
|
||
|
||
This is the flow I recommend for **maximum cost control + quality** based on your plugin's design.
|

|
||
### Step-by-Step

### Key Features of Option A
|
||
|
||
✅ **Cost control:** User sees cost before spending
|
||
✅ **Quality control:** Can edit prompts before generation
|
||
✅ **Flexibility:** Generate 0, 1, 2, or 3 images
|
||
✅ **User review:** Know exactly what images they'll get
|
||
✅ **Selective generation:** Generate only what matters
|
||
✅ **Smart placement:** Analyzed by writing agent (best understanding)
|
||
✅ **Efficient prompts:** Precise, contextual, no trial-and-error
|
||
|
||
### Costs with Option A
|
||
|
||
| Scenario | Analysis | Prompts | Images | Total |
|
||
|----------|----------|---------|--------|-------|
|
||
| User generates all 3 | $0.0008 | $0.0015 | $0.09–0.21 | $0.092–0.212 |
|
||
| User generates 2 | $0.0008 | $0.0015 | $0.06–0.14 | $0.063–0.142 |
|
||
| User generates 1 (hero) | $0.0008 | $0.0015 | $0.03–0.07 | $0.032–0.072 |
|
||
| User skips images | $0.0008 | $0.0015 | $0 | $0.0023 |
|
||
|
||
**Best case:** User generates 1 hero = **$0.032–0.072/article** (vs $0.21–0.70 with trial-and-error)
|
||
|
||
---
|
||
|
||
## Alternative Flows (B & C)
|
||
|
||
### Option B: Automatic Full Generation (FASTEST)
|
||
|
||
```
|
||
Article generated
|
||
↓
|
||
Plugin automatically generates ALL images without review
|
||
↓
|
||
"Article + images ready!" (1-2 minutes total)
|
||
```
|
||
|
||
**Pros:** One-click, minimal user interaction
|
||
**Cons:** Always costs full image budget (no user control)
|
||
**Cost:** Full $0.12–0.35 (analysis + all images always generated)
|
||
|
||
**Use when:** User has unlimited budget OR you offer it as "premium fast mode"
|
||
|
||
---
|
||
|
||
### Option C: Smart Selective with Recommendations (BALANCED)
|
||
|
||
```
|
||
Similar to Option A, but plugin recommends:
|
||
- "Hero image has best impact/cost ratio" [Generate hero]
|
||
- "Diagrams help understanding" [Generate diagram?]
|
||
- "Screenshot is optional" [Generate?]
|
||
```
|
||
|
||
**Pros:** Guides user toward cost-effective choices
|
||
**Cons:** Slightly more UI complexity
|
||
**Cost:** User-controlled (guided)
|
||
|
||
**Use when:** You want to educate users about cost-benefit tradeoffs
|
||

|
||
|
||
## Your Configuration (from screenshot)
|
||
|
||
Based on your current model configuration:
|
||
|
||
```
|
||
Chat Model: Google: Gemini 2.5 Flash
|
||
Clarity Model: Google: Gemini 2.5 Flash
|
||
Planning Model: Google: Gemini 2.5 Flash
|
||
Writing Model: Anthropic: Claude 3.5 Sonnet
|
||
Refinement Model: Anthropic: Claude 3.5 Sonnet
|
||
Image Model: Gpt 4o (or FLUX.2 from preset)
|
||
```
|
||
|
||
### Recommended Implementation
|
||
|
||
```php
|
||
// Option A implementation (safest, recommended)
|
||
|
||
// 1. After article generation, automatically:
|
||
$placement_data = analyze_article_for_images(
|
||
$article,
|
||
'anthropic/claude-3.5-sonnet' // Use same writing model
|
||
);
|
||
|
||
// 2. Generate prompts
|
||
$image_specs = generate_image_prompts(
|
||
$article,
|
||
$placement_data,
|
||
'anthropic/claude-3.5-sonnet' // Same model
|
||
);
|
||
|
||
// 3. Show UI (don't generate images yet)
|
||
show_image_review_modal($image_specs);
|
||
|
||
// 4. User clicks [Generate All] or individual [Generate]
|
||
// 5. Only then call image generation
|
||
|
||
// Cost so far: $0.0023 (tiny)
|
||
// User controls image generation cost: $0.03–0.21
|
||
```
|
||

|
||
|
||
## Cost Breakdown
|
||
|
||
### Analysis + Prompt Generation (Automatic, Non-Optional)
|
||
|
||
| Task | Tokens In | Tokens Out | Cost |
|
||
|------|-----------|------------|------|
|
||
| Placement analysis | 2,000 | 800 | $0.0008 |
|
||
| Prompt generation | 3,000 | 1,000 | $0.0015 |
|
||
| **Total** | **5,000** | **1,800** | **$0.0023** |
|
||
|
||
**This is already paid by article generation (uses writing model already called).**
|
||
|
||
### Image Generation (User-Controlled)
|
||
|
||
**Per image (based on model tier):**
|
||
|
||
| Image Model | Cost/Image | 3 Images |
|
||
|------------|-----------|----------|
|
||
| FLUX.2 klein (Budget) | $0.03–0.05 | $0.09–0.15 |
|
||
| Riverflow/FLUX.2 Pro (Balanced) | $0.06–0.10 | $0.18–0.30 |
|
||
| FLUX.2 max (Premium) | $0.07–0.21 | $0.21–0.63 |
|
||
|
||
### Total Article Cost
|
||
|
||
| Scenario | Text | Analysis | Prompts | Images | Total |
|
||
|----------|------|----------|---------|--------|-------|
|
||
| Article only | $0.03–0.07 | $0.0008 | $0.0015 | $0 | **$0.032–0.072** |
|
||
| Article + 1 hero | $0.03–0.07 | $0.0008 | $0.0015 | $0.03–0.21 | **$0.062–0.292** |
|
||
| Article + 2 images | $0.03–0.07 | $0.0008 | $0.0015 | $0.06–0.42 | **$0.092–0.492** |
|
||
| Article + 3 images | $0.03–0.07 | $0.0008 | $0.0015 | $0.09–0.63 | **$0.122–0.702** |
|
||
|

|
||
|
||
## Implementation Priority
|
||
|
||
### Phase 1: Core Logic (3-4 hours)
|
||
|
||
```php
|
||
✓ analyze_article_for_images() // Identify placements
|
||
✓ generate_image_prompts() // Create specs
|
||
✓ generate_image_from_prompt() // Call image model
|
||
✓ insert_images_into_article() // Embed in markdown
|
||
```
|
||
|
||
### Phase 2: User Interface (4-5 hours)
|
||
|
||
```php
|
||
✓ Image review modal UI // Show 3 specs
|
||
✓ [Generate] button per image // Individual generation
|
||
✓ [Generate All] button // Batch generation
|
||
✓ [Edit Prompt] capability // Let users customize
|
||
✓ Cost calculator display // Show estimated cost
|
||
```
|
||
|
||
### Phase 3: Polish (2-3 hours)
|
||
|
||
```php
|
||
✓ Image preview before insertion // Show user the image
|
||
✓ Error handling + retry logic // Handle failures
|
||
✓ Success notifications // Feedback
|
||
✓ Progress indicators // "Generating image 2/3..."
|
||
```
|
||
|
||

|
||
|
||
## Why Option A is Best for Your Plugin
|
||
|
||
1. **User controls costs** → They see preview before spending
|
||
2. **Respects budgets** → Budget tier users generate 1 image
|
||
3. **Quality focus** → Users can edit prompts if needed
|
||
4. **Flexible** → Some users skip images entirely (saves costs)
|
||
5. **Educational** → Users learn what good prompts look like
|
||
6. **Smart prompts** → Using writing agent (best context understanding)
|
||
|
||
---
|
||
|
||
## Summary: Recommended Best Flow
|
||
|
||
```
|
||
AUTOMATIC (Backend):
|
||
1. Analyze article for placement → $0.0008
|
||
2. Generate image specs/prompts → $0.0015
|
||
3. Show user preview modal → $0 (free review)
|
||
|
||
MANUAL (User Selects):
|
||
4. User clicks [Generate] on images → User controls cost
|
||
5. Plugin inserts into article → Automatic
|
||
|
||
RESULT:
|
||
- Article + images ready for Gutenberg
|
||
- User spent only what they wanted
|
||
- Total cost: $0.032–0.702 (user-controlled)
|
||
- Quality: High (smart placement + customizable prompts)
|
||
```
