GPT-5 Specific Requirements ⚠️

Critical Differences from GPT-4

1. Parameter Name Change:

// ❌ 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:

// ❌ 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):

// ✅ New GPT-5 parameter
reasoning_effort: 'medium'  // Options: 'minimal', 'low', 'medium', 'high'

Updated Request Format

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:

{
  "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:

{
  "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:

// 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:

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

// 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):

AZURE_OPENAI_REASONING_EFFORT=low
AZURE_OPENAI_CHAT_MAX_TOKENS=500

For Complex Analysis:

AZURE_OPENAI_REASONING_EFFORT=high
AZURE_OPENAI_CHAT_MAX_TOKENS=2000

For Quick Responses:

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

---
