OpenAI Function Calling Format (5K)

Synthetic function-calling conversations in the OpenAI messages format (tool_calls / tool role).

Why This Dataset

Compatible with GPT-4, Mistral, Llama-3.1, Qwen2.5, and any model trained on the OpenAI chat format. Most existing function-calling datasets use abstract schemas — this uses the exact wire format models see in production.

Dataset Description

5,000 conversations across 10 tool types:

Tool	Single-turn	Multi-turn
get_weather	✓	—
get_stock_price	✓	✓
search_web	✓	✓
execute_python	✓	✓
query_database	✓	—
send_email	✓	✓
create_calendar_event	✓	—
translate_text	✓	—
read_file	✓	✓
create_chart	✓	—

• ~80% single-turn (one tool call → result → response)
• ~20% multi-turn (sequential tool calls, e.g. search then email)

Format

Exact OpenAI messages format:

{
  "messages": [
    {"role": "system", "content": "You are a helpful AI assistant..."},
    {"role": "user", "content": "What's the weather in Tokyo?"},
    {
      "role": "assistant",
      "content": null,
      "tool_calls": [{
        "id": "call_abc123",
        "type": "function",
        "function": {"name": "get_weather", "arguments": "{"location": "Tokyo, Japan"}"}
      }]
    },
    {"role": "tool", "content": "{"temperature": 28, ...}", "tool_call_id": "call_abc123"},
    {"role": "assistant", "content": "Current weather in Tokyo: 28°C..."}
  ],
  "tools": [{"type": "function", "function": {...}}],
  "metadata": {"type": "single_turn", "tool": "get_weather"},
  "id": "abc123"
}

Use Case

• Fine-tune LLMs for function calling (SFT on chosen response)
• Train tool-selection and argument generation
• Evaluate function-calling capability
• Drop-in compatible with OpenAI fine-tuning API format (with minor adaptation)
