In practice: querying data with GPT-4o
from openai import OpenAI
import os
client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])
query = "Write a SQL query to find the top 5 products by sales in 2025"
response = client.chat.completions.create(
model="gpt-4o",
messages=[{"role": "user", "content": query}]
)
print(response.choices[0].message.content)SELECT product_name, SUM(sales) AS total_sales FROM sales_data WHERE sales_year = 2025 GROUP BY product_name ORDER BY total_sales DESC LIMIT 5;

What to avoid
- Avoid older models like
gpt-3.5-turboorclaude-2as they lack the accuracy and context length needed for complex data analysis. - Do not rely solely on open-source LLMs without fine-tuning for data tasks; they often underperform on coding and data reasoning benchmarks.
- Avoid models with limited context windows (<8K tokens) for large dataset summaries or multi-turn data conversations.
How to evaluate for your case
Benchmark models on your typical data queries and scripts by measuring accuracy, latency, and cost. Use datasets with real SQL or Python tasks and compare output correctness. Test embedding quality with semantic search relevance. Prioritize models with longer context windows if your workflows involve large datasets or multi-step analysis.
