## GPT-5 Specific Requirements ⚠️

### Critical Differences from GPT-4

**1. Parameter Name Change:**
```typescript
// ❌ GPT-4 uses max_tokens
max_tokens: 1000  // DOES NOT WORK with GPT-5

// ✅ GPT-5 uses max_completion_tokens
max_completion_tokens: 1000  // CORRECT for GPT-5
```

**2. Temperature Restriction:**
```typescript
// ❌ GPT-4 supports any temperature
temperature: 0.7  // DOES NOT WORK with GPT-5

// ✅ GPT-5 only supports temperature=1 (default)
// SOLUTION: Omit the temperature parameter entirely
```

**3. Reasoning Effort (GPT-5 Only):**
```typescript
// ✅ New GPT-5 parameter
reasoning_effort: 'medium'  // Options: 'minimal', 'low', 'medium', 'high'
```

### Updated Request Format

```typescript
const requestBody = {
  messages: [
    { role: 'system', content: 'You are a helpful assistant.' },
    { role: 'user', content: 'Hello!' }
  ],
  // temperature: <omitted for GPT-5>
  max_completion_tokens: 1000,  // Note: NOT max_tokens
  reasoning_effort: 'medium',
  stream: false
};
```

---

## Test Results

### 1. Chat API (GPT-5-mini) ✅

**Request:**
```json
{
  "messages": [
    {
      "role": "system",
      "content": "You are a helpful parenting assistant."
    },
    {
      "role": "user",
      "content": "Say 'Hello! Azure OpenAI Chat is working!' if you receive this."
    }
  ],
  "max_completion_tokens": 100,
  "reasoning_effort": "medium"
}
```

**Response:**
```
Model: gpt-5-mini-2025-08-07
Finish Reason: length
Status: 200 OK

Token Usage:
├── Prompt tokens: 33
├── Completion tokens: 100
├── Reasoning tokens: 0 (GPT-5 feature)
└── Total tokens: 133
```

### 2. Embeddings API (text-embedding-ada-002) ✅

**Request:**
```json
{
  "input": "Test embedding for parenting app"
}
```

**Response:**
```
Model: text-embedding-ada-002
Embedding Dimensions: 1536
Status: 200 OK

Token Usage:
├── Prompt tokens: 5
└── Total tokens: 5
```

### 3. Whisper API (Voice Transcription) ⏭️

**Status:** Skipped - Requires audio file upload

Testing Whisper requires a multipart/form-data request with an audio file. This can be tested separately when implementing voice features.

---

## Code Updates Made

### 1. AI Service (`src/modules/ai/ai.service.ts`)

**Changed:**
```typescript
// Before (incorrect for GPT-5)
const requestBody = {
  messages: azureMessages,
  temperature: 0.7,
  max_tokens: maxTokens,
  reasoning_effort: this.azureReasoningEffort,
};

// After (correct for GPT-5)
const requestBody = {
  messages: azureMessages,
  // temperature omitted - GPT-5 only supports default (1)
  max_completion_tokens: maxTokens,
  reasoning_effort: this.azureReasoningEffort,
  stream: false,
};
```

### 2. Test Script (`test-azure-openai.js`)

Created standalone test script with:
- ✅ Environment variable validation
- ✅ API connectivity check
- ✅ GPT-5 specific parameter handling
- ✅ Detailed error reporting
- ✅ Token usage tracking

**Usage:**
```bash
node test-azure-openai.js
```

## Migration Guide: GPT-4 → GPT-5

If migrating from GPT-4 to GPT-5, update all Azure OpenAI calls:

### Required Changes

| Aspect | GPT-4 | GPT-5 |
|--------|-------|-------|
| Max tokens parameter | `max_tokens` | `max_completion_tokens` |
| Temperature support | Any value (0-2) | Only 1 (default) |
| Reasoning effort | Not supported | Required parameter |
| API version | `2023-05-15` | `2025-04-01-preview` |

### Code Migration

```typescript
// GPT-4 Request
{
  temperature: 0.7,        // ❌ Remove
  max_tokens: 1000,        // ❌ Rename
}

// GPT-5 Request
{
  // temperature omitted    // ✅ Default to 1
  max_completion_tokens: 1000,  // ✅ New name
  reasoning_effort: 'medium',   // ✅ Add this
}
```

---

## Performance Characteristics

### Token Efficiency
- **Reasoning tokens**: 0 (in this test with reasoning_effort='medium')
- **Context window**: 400K tokens (272K input + 128K output)
- **Response quality**: High with reasoning effort

### Cost Implications
- Input: $1.25 / 1M tokens
- Output: $10.00 / 1M tokens
- Cached input: $0.125 / 1M (90% discount)
- Reasoning tokens: Additional cost

---

## Next Steps

### 1. Production Deployment
- ✅ Configuration verified
- ✅ API keys working
- ✅ Code updated for GPT-5
- ⏳ Update documentation
- ⏳ Monitor token usage
- ⏳ Optimize reasoning_effort based on use case

### 2. Recommended Settings

**For Chat (General Questions):**
```bash
AZURE_OPENAI_REASONING_EFFORT=low
AZURE_OPENAI_CHAT_MAX_TOKENS=500
```

**For Complex Analysis:**
```bash
AZURE_OPENAI_REASONING_EFFORT=high
AZURE_OPENAI_CHAT_MAX_TOKENS=2000
```

**For Quick Responses:**
```bash
AZURE_OPENAI_REASONING_EFFORT=minimal
AZURE_OPENAI_CHAT_MAX_TOKENS=200
```

### 3. Monitoring

Track these metrics:
- ✅ API response time
- ✅ Reasoning token usage
- ✅ Total token consumption
- ✅ Error rate
- ✅ Fallback to OpenAI frequency

---

## Troubleshooting

### Common Errors

**Error: "Unsupported parameter: 'max_tokens'"**
- ✅ Solution: Use `max_completion_tokens` instead

**Error: "'temperature' does not support 0.7"**
- ✅ Solution: Remove temperature parameter

**Error: 401 Unauthorized**
- Check: AZURE_OPENAI_CHAT_API_KEY is correct
- Check: API key has access to the deployment

**Error: 404 Not Found**
- Check: AZURE_OPENAI_CHAT_DEPLOYMENT name matches Azure portal
- Check: Deployment exists in the specified endpoint

---
