URL: /admin/reports/ai-cost-analysis/

Current Status: ❌ NOT IMPLEMENTED
Action NEEDED: ✅ COPY THIS IMPLEMENTATION

2. Admin Templates (✅ IMPLEMENTED IN COMMITS)

✅ Token Usage Template

Location: backend/igny8_core/templates/admin/reports/token_usage.html
Features:

  • Chart.js visualizations (line charts, bar charts, pie charts)
  • Token breakdown by model, function, account
  • Daily trends with date range filter
  • Hourly heatmap for peak usage times
  • Export data functionality

Current Status: ❌ NOT IMPLEMENTED

✅ AI Cost Analysis Template

Location: backend/igny8_core/templates/admin/reports/ai_cost_analysis.html
Features:

  • Cost visualizations (line charts, bar charts)
  • Model cost comparison table
  • Anomaly detection table (expensive calls)
  • Projected monthly costs
  • Cost efficiency metrics
  • Export to CSV functionality

Current Status: ❌ NOT IMPLEMENTED

3. Database Models & Migrations (⚠️ PARTIALLY DIFFERENT)

❌ BillingConfiguration Model (REMOVED IN OUR APPROACH)

Previous Implementation:

class BillingConfiguration(models.Model):
    default_tokens_per_credit = models.IntegerField(default=100)
    default_credit_price_usd = models.DecimalField(default=0.01)
    rounding_mode = models.CharField(choices=[('up', 'Up'), ('down', 'Down'), ('nearest', 'Nearest')])
    token_reporting_enabled = models.BooleanField(default=True)

Our Implementation: ✅ REPLACED WITH AIModelConfig

  • Instead of global tokens_per_credit, we use per-model ratios
  • More flexible (GPT-4 = 50 tokens/credit, GPT-3.5 = 200 tokens/credit)

⚠️ CreditCostConfig Updates (SIMILAR BUT DIFFERENT)

Previous Implementation:

class CreditCostConfig:
    tokens_per_credit = IntegerField  # Per-operation ratio
    min_credits = IntegerField
    price_per_credit_usd = DecimalField

Our Implementation: ✅ BETTER APPROACH

class CreditCostConfig:
    unit = CharField(choices=[..., 'per_100_tokens', 'per_1000_tokens'])  # Token units added
    default_model = FK(AIModelConfig)  # Links to centralized model config

Difference:

  • Previous: Each operation had its own tokens_per_credit
  • Current: Operations reference a shared AIModelConfig with unified pricing

✅ CreditUsageLog Fields (MOSTLY SAME)

Previous Implementation:

class CreditUsageLog:
    tokens_input = IntegerField
    tokens_output = IntegerField
    cost_usd = DecimalField
    model_used = CharField(max_length=100)

Our Implementation: ✅ ENHANCED

class CreditUsageLog:
    tokens_input = IntegerField
    tokens_output = IntegerField
    cost_usd_input = DecimalField  # NEW: Separate input cost
    cost_usd_output = DecimalField  # NEW: Separate output cost
    cost_usd_total = DecimalField  # NEW: Total cost
    model_config = FK(AIModelConfig)  # NEW: FK instead of string
    model_name = CharField  # Kept for backward compatibility

Status: ✅ OUR APPROACH IS BETTER (granular cost tracking)

4. Credit Calculation Logic (✅ IMPLEMENTED BY US)

✅ Token-Based Credit Calculation

Previous Implementation:

def calculate_credits(tokens_input, tokens_output, operation_type):
    config = CreditCostConfig.objects.get(operation_type=operation_type)
    total_tokens = tokens_input + tokens_output
    credits = total_tokens / config.tokens_per_credit
    return max(credits, config.min_credits)

Our Implementation: ✅ SIMILAR + MODEL-AWARE

def calculate_credits_from_tokens(operation_type, tokens_input, tokens_output, model_config):
    config = CreditCostConfig.objects.get(operation_type=operation_type)
    total_tokens = tokens_input + tokens_output
    tokens_per_credit = model_config.tokens_per_credit  # Model-specific ratio
    credits = total_tokens / tokens_per_credit
    return max(credits, config.credits_cost)

Status: ✅ IMPLEMENTED (our approach is more flexible)

✅ Model Selection Logic

Previous Implementation: ❌ NOT PRESENT (used global default)

Our Implementation: ✅ IMPLEMENTED

def get_model_for_operation(account, operation_type, task_override=None):
    # Priority: Task > Account Default > Operation Default > System Default
    if task_override:
        return task_override
    if account.integration.default_text_model:
        return account.integration.default_text_model
    if operation_config.default_model:
        return operation_config.default_model
    return AIModelConfig.objects.get(is_default=True)

Status: ✅ NEW FEATURE (not in previous commits)

5. AIEngine Updates (⚠️ PARTIALLY IMPLEMENTED)

✅ Token Extraction (BOTH HAVE IT)

Previous Implementation:

tokens_input = raw_response.get('input_tokens', 0)
tokens_output = raw_response.get('output_tokens', 0)

Our Implementation: ❌ NOT YET IN AIEngine Action Needed: Need to update backend/igny8_core/ai/engine.py to extract tokens

6. Management Commands (✅ IMPLEMENTED IN COMMITS)

✅ Backfill Tokens Command

Location: backend/igny8_core/management/commands/backfill_tokens.py
Purpose: Migrate old CreditUsageLog records to have token data

Current Status: ❌ NOT IMPLEMENTED (but may not be needed if we don't have legacy data)

7. Integration with Services (⚠️ PARTIALLY IMPLEMENTED)

Previous Implementation:

  • Updated linker_service.py to pass tokens
  • Updated optimizer_service.py to pass tokens
  • Other services not modified

Our Implementation:

  • ❌ NOT YET UPDATED (Phase 2.3 - pending)
  • Need to update: clustering, ideas, content, image, optimizer, linker services

What's Missing from Our Current Implementation

❌ Critical Missing Features (Should Copy from Commits)

  1. Token Usage Report (token_usage_report view + template)

    • Full analytics with charts
    • By model, function, account, time
    • Export functionality

  2. AI Cost Analysis Report (ai_cost_analysis view + template)

    • Cost tracking and forecasting
    • Anomaly detection
    • Model cost comparison

  3. Admin URL Routes (register the reports)

    • Need to add to backend/igny8_core/admin/site.py

  4. AIEngine Token Extraction

    • Extract input_tokens, output_tokens from AI responses
    • Pass to CreditService

  5. Service Updates (Phase 2.3)

    • Update all AI services to use token-based calculation
    • Pass model_config, tokens_input, tokens_output

What We Did Better

✅ Improvements Over Previous Commits

  1. AIModelConfig Model

    • Centralized pricing (one source of truth)
    • Support multiple providers (OpenAI, Anthropic, Runware)
    • Per-model token ratios (GPT-4 ≠ GPT-3.5)
    • Easier to add new models

  2. Granular Cost Tracking

    • Separate cost_usd_input and cost_usd_output
    • Can track input vs output costs accurately
    • Better for margin analysis

  3. Model Selection Priority

    • Task override > Account default > Operation default > System default
    • More flexible than global default

  4. IntegrationSettings Enhancement

    • Account-level model selection
    • default_text_model and default_image_model
    • Per-account cost optimization

  5. Cleaner Migration Path

    • Previous: Changed field types (risky)
    • Current: Added new fields, kept old for compatibility

Action Items

✅ Phase 1: COMPLETE

  • AIModelConfig model
  • Migrations applied
  • Seed data (7 models)
  • Admin interface

🔄 Phase 2: IN PROGRESS

  • CreditService.calculate_credits_from_tokens()
  • CreditService.get_model_for_operation()
  • Updated deduct_credits() with model_config FK
  • Update AIEngine to extract tokens
  • Update AI services (clustering, ideas, content, image, optimizer, linker)

❌ Phase 3: ANALYTICS (COPY FROM COMMITS)

  • Copy token_usage_report() from commit c17b22e9
  • Copy ai_cost_analysis() from commit e041cb8e
  • Copy token_usage.html template
  • Copy ai_cost_analysis.html template
  • Register URLs in admin site

❌ Phase 4: TESTING & DOCUMENTATION

  • Test token-based calculation end-to-end
  • Verify reports work with new data
  • Update user documentation

Conclusion

Previous Commits: Comprehensive token system with excellent analytics, but over-engineered with per-operation configs

Current Implementation: Cleaner architecture with centralized AIModelConfig, better model selection, but missing the analytics dashboards

Best Path Forward:

  1. ✅ Keep our Phase 1 foundation (AIModelConfig approach is superior)
  2. ✅ Complete Phase 2 (CreditService mostly done, need AIEngine + services)
  3. 📋 Copy Phase 3 analytics from commits (token_usage_report + ai_cost_analysis)
  4. 🧪 Test everything end-to-end

Timeline:

  • Phase 2 completion: 1-2 hours (AIEngine + service updates)
  • Phase 3 analytics: 30-60 minutes (copy + adapt templates)
  • Phase 4 testing: 30 minutes

Estimated Total: 2-3 hours to full implementation
