## Speed Optimization Techniques

### 1. Fast LLM Models
```python
# Groq - Ultra-fast inference
from openbrowser import ChatGroq
llm = ChatGroq(model='meta-llama/llama-4-maverick-17b-128e-instruct')

# Google Gemini Flash - Optimized for speed
from openbrowser import ChatGoogle
llm = ChatGoogle(model='gemini-flash-lite-latest')
```

### 2. Browser Optimizations
```python
browser_profile = BrowserProfile(
    minimum_wait_page_load_time=0.1,    # Reduce wait time
    wait_between_actions=0.1,           # Faster action execution
    headless=True,                      # No GUI overhead
)
```

### 3. Agent Optimizations
```python
agent = Agent(
    task=task,
    llm=llm,
    flash_mode=True,                    # Skip LLM thinking process
    extend_system_message=SPEED_PROMPT, # Optimize LLM behavior
)
```
