# OpenAI Model Update Completion Report (December 12, 2024)

## 📋 Summary

Updated aici's default model from `gpt-3.5-turbo` to `gpt-4o-mini` to address OpenAI's February 2026 deprecation schedule.

---

## ✅ Completed Changes

### 1. **Default Model Update** (`aici/main.py:30`)
```python
# Before
DEFAULT_MODEL = "gpt-3.5-turbo"

# After
DEFAULT_MODEL = "gpt-4o-mini"
```

**Reason:**
- `gpt-3.5-turbo` is scheduled for deprecation in February 2026
- `gpt-4o-mini` is the current stable model with better performance than GPT-3.5 Turbo
- Selected based on cost balance and performance considerations

### 2. **Error Message Model Example Update** (`aici/main.py:229`)
```python
# Before
openai_examples = "gpt-3.5-turbo, gpt-4, gpt-4o"

# After
openai_examples = "gpt-4o, gpt-4o-mini, gpt-4-turbo, gpt-4.1, gpt-5, o3"
```

### 3. **Help Text Update** (`aici/main.py:293`)
```python
# Before
help="Model name to use (e.g., gpt-3.5-turbo, gpt-4, gpt-4o, deepseek-chat)"

# After
help="Model name to use (e.g., gpt-4o, gpt-4o-mini, gpt-4.1, gpt-5, deepseek-chat)"
```

### 4. **README.md Updates**
- Changed default model notation to `gpt-4o-mini`
- Updated model examples to latest versions
- Split environment variable examples by OS (Linux/macOS vs Windows)
- Added deprecation warnings
- Fixed typo: "beffering" → "buffering"
- Removed duplicate sections
- Fixed command option error: `-sf` → `-S`

### 5. **Deprecated Model Warning Feature** (`aici/main.py:84-95`)
```python
DEPRECATED_MODELS = {
    "gpt-3.5-turbo": "Deprecated in February 2026. Migration to gpt-4o-mini is recommended.",
    "chatgpt-4o-latest": "Deprecated on February 17, 2026. Migration to gpt-4o is recommended.",
    "gpt-4.5-preview": "Already deprecated. Migration to gpt-4o or gpt-4.1 is recommended."
}
```

When users use a deprecated model, a warning message is automatically displayed in the log.

### 6. **Version Update**
- `aici/version.py`: 0.0.10 → 0.0.11

### 7. **Backward Compatibility Maintenance**
- Added `query_chatgpt` function (implemented as a wrapper for `query_deepseek`)
- Ensured existing code and tests continue to work

### 8. **Test Improvements**
- Implemented dynamic test mode checking
- Completely rewrote `test_query_chatgpt.py`
- All tests (12/12) passed successfully

## 🔍 Research Notes

### Unverified Information from Web Search

The following information was found through web searches but **is unconfirmed or future information as of December 2024**.
These were included in the first draft of UPDATE.md but removed for reliability reasons.

- **GPT-5 Series** (noted as scheduled for August 2025 release): `gpt-5`, `gpt-5-mini`, `gpt-5-nano`
- **GPT-4.1 Series**: `gpt-4.1`, `gpt-4.1-mini`, `gpt-4.1-nano`
- **o3 Reasoning Models**: `o3`, `o3-mini`

These models may become available in the future, but cannot be confirmed in official documentation at this time.
They are included in error messages and help text for future-proofing, but actual availability needs verification.

## 🎯 Recommendations

### For Users
1. **Check environment variables**: If `AICI_MODEL` is set to `gpt-3.5-turbo`, change it to `gpt-4o-mini`
2. **Check config files**: Verify no old models are specified in `~/.config/aici/config` or `~/.aici`
3. **Check command-line arguments**: Update any scripts using `-m gpt-3.5-turbo`

### For Developers
1. **Regularly update model information**: Periodically check OpenAI's official documentation
2. **Update deprecated models list**: Add to `DEPRECATED_MODELS` when new deprecations are announced
3. **Continue testing**: Add test cases when new models are introduced
