-# GAIA Agent Improvements - Implementation Guide
-
-## Phase 1: Update LLM Tiers (Lines 63-69 in agent.py)
-
-Replace the tiers_config list with:
-
-```python
-tiers_config = [
-    {"name": "OpenRouter-FreeRouter", "key": "OPENROUTER_API_KEY", "provider": "openai", "model_name": "openrouter/free", "base_url": "https://openrouter.ai/api/v1"},
-    {"name": "DeepSeek-R1", "key": "OPENROUTER_API_KEY", "provider": "openai", "model_name": "deepseek/deepseek-r1:free", "base_url": "https://openrouter.ai/api/v1"},

-    {"name": "Groq", "key": "GROQ_API_KEY", "provider": "groq", "model_name": "llama-3.3-70b-versatile"},
-]
-```
-
-## Phase 2: Update Vision Models (Lines 180-186 in agent.py)
-
-Replace the vision model configs with:
-
-```python
-configs = [
-    {"name": "OpenRouter-Qwen3-VL", "key": "OPENROUTER_API_KEY", "provider": "openai", "model_name": "qwen/qwen3-vl-235b-thinking:free", "base_url": "https://openrouter.ai/api/v1"},

-    {"name": "Google-Gemini-Flash-Latest", "key": "GOOGLE_API_KEY", "provider": "google", "model_name": "gemini-flash-latest"},
-]
-```
-
-## Phase 3: Enhance System Prompt (Lines 495-506 in agent.py)
-
-Replace the system prompt in answer_message function with:
-
-```python
-prompt = [SystemMessage(f"""
-You are a master of the GAIA benchmark, a general AI assistant designed to solve complex multi-step tasks.
-Think carefully and logically. Use your tools effectively. Use your internal monologue to plan your steps.
-
-TODAY'S EXACT DATE is {current_date}. Keep this in mind for all time-sensitive queries.
-
-CRITICAL RULES:
-1. If you see a path like `[Attached File Local Path: ...]` followed by an image, video, or audio file, YOU MUST USE THE CORRESPONDING TOOL (analyze_image, analyze_video, analyze_audio) IMMEDIATELY in your next step.
-2. Plan your steps ahead. 12 steps is your LIMIT for the reasoning loop, so make every step count.
-3. If a tool fails (e.g., 429 or 402), the system will automatically try another model for you, so just keep going!
-4. Be concise and accurate. YOUR FINAL ANSWER should be a number OR as few words as possible OR a comma separated list.
-5. CHAIN-OF-THOUGHT: For complex questions, show your reasoning step by step before giving the final answer.
-6. USE TOOLS AGGRESSIVELY: If a question requires computation, file reading, or web search, use the appropriate tools don't try to answer from memory.
-7. VERIFY YOUR ANSWER: Double-check calculations and facts using tools when uncertain.
-""")]
-```
-
-## Phase 4: Increase Max Reasoning Steps (Line 515)
-
-Change:
-```python
-max_steps = 8
-```
-To:
-```python
-max_steps = 12
-```
-
-## Phase 5: Fix Answer Extraction (Lines 564-575)
-
-Replace the formatting system message with:
-
-```python
-formatting_sys = SystemMessage(
-    content=(
-        "You are a strict output formatter for the GAIA benchmark. "
-        "Given a verbose draft answer, extract ONLY the final exact answer required. "
-        "Return nothing else. DO NOT include prefixes like 'The answer is'. "
-        "Strip trailing whitespace only. "
-        "If the answer is a number, just return the number. "
-        "If the answer is a list or set of elements, return them as a COMMA-SEPARATED list (e.g., 'a, b, c'). "
-        "Preserve necessary punctuation within answers (e.g., 'Dr. Smith' should keep the period)."
-    )
-)
-```
-
-## Phase 6: Tool Improvements
-
-### 6a. Web Search Retry (Lines 146-152 in web_search tool)
-
-Replace web_search tool body with:
-
-```python
-@tool
-def web_search(keywords: str) -> str:
-    """
-    Uses duckduckgo to search the top 5 result on web
-    """
-    max_retries = 3
-    for attempt in range(max_retries):
-        try:
-            with DDGS() as ddgs:
-                output = ""
-                results = ddgs.text(keywords, max_results=5)
-                for result in results:
-                    output += f"Results: {result['title']}\n{result['body']}\n{result['href']}\n\n"
-                return output
-        except Exception as e:
-            if attempt < max_retries - 1:
-                time.sleep(2 ** attempt)  # Exponential backoff
-                continue
-            return f"Search failed after {max_retries} attempts: {str(e)}"
-```
-
-### 6b. Python Script Timeout (Line 401)
-
-Change:
-```python
-timeout=30
-```
-To:
-```python
-timeout=60
-```
-
----
-
-## Expected Impact
-
-- Phase 1-2 (Models): +8-12 questions (40-60% improvement)
-- Phase 3-4 (Prompt): +2-4 questions (10-20% improvement)  
-- Phase 5-6 (Tools): +1-2 questions (5-10% improvement)

-Total: From 2/20 (10%) to 13-18/20 (65-90%)
