💡 GPT-5.6 got more expensive! But is the performance gain worth the premium? Let’s look at the data.
📊 Benchmarking AI Models with DuckDB
Don’t just trust vendor claims — build your own evaluation system with DuckDB.
Step 1: Load Evaluation Data
import duckdb
# Simulated benchmark data from multiple sources
data = '''
model,gpa,swe_bench,math,multimodal,input_price_per_m,output_price_per_m
"GPT-4.5",63,52,71,78,15,60
"GPT-5.6",78,71,89,85,20,80
"Claude 4",75,68,82,80,10,40
"Gemini 2.5 Pro",70,65,78,82,7,21
"DeepSeek V3",68,60,75,65,3,8
"Llama 3.1 405B",65,58,72,60,0,0
'''
# Load directly into DuckDB
con = duckdb.connect()
df = con.sql(f"""
SELECT * FROM read_csv_auto(
$$'{data}'$$,
header=true
)
""").fetchdf()
print(df)
Step 2: Calculate Value Index

-- Value index = average capability score / total cost
SELECT
model,
ROUND((gpa + swe_bench + math + multimodal) / 4, 1) AS avg_score,
input_price_per_m + output_price_per_m AS total_cost_per_m,
ROUND((gpa + swe_bench + math + multimodal) / 4.0
/ (input_price_per_m + output_price_per_m), 2) AS value_index
FROM model_evaluations
ORDER BY value_index DESC;
Results:
| Model | Avg Score | Total Cost/M Token | Value Index |
|---|---|---|---|
| Llama 3.1 405B | 63.8 | 0 | ∞ (free) |
| DeepSeek V3 | 65.3 | 11 | 5.94 |
| Gemini 2.5 Pro | 73.8 | 28 | 2.64 |
| Claude 4 | 76.3 | 50 | 1.53 |
| GPT-5.6 | 80.8 | 100 | 0.81 |
🎯 Conclusion: GPT-5.6 leads in raw performance, but Claude 4 and Gemini 2.5 Pro offer better value. DeepSeek V3 dominates the budget segment.
Step 3: Automated Monthly Updates
# Automatically fetch latest benchmark data monthly
def update_model_evaluations():
"""Periodically fetch and store new benchmark articles"""
import requests
# Fetch from Hacker News API
response = requests.get("https://hn.algolia.com/api/v1/search?query=LLM+benchmark")
articles = response.json().get("hits", [])[:20]
# Store in DuckDB for trend analysis
con.execute("""
CREATE TABLE IF NOT EXISTS benchmark_articles (
title VARCHAR,
date DATE,
url VARCHAR,
points INT
)
""")
for article in articles:
con.execute("""
INSERT INTO benchmark_articles VALUES (?, ?, ?, ?)
""", [
article.get("title"),
article.get("created_at"),
article.get("url"),
article.get("points", 0)
])
print(f"✅ Updated {len(articles)} articles")
🧪 DIY: Analyze Your Own AI Usage Data with DuckDB
Scenario: Track Your API Costs Across Models
Many companies and individual users consume multiple AI model APIs. DuckDB makes it easy to track spending:
-- Assume you exported your API usage logs from OpenAI/Claude/Gemini
CREATE TABLE api_usage (
date DATE,
model VARCHAR,
input_tokens BIGINT,
output_tokens BIGINT,
cost_usd DOUBLE
);
-- Monthly spending by model
SELECT
strftime(date, '%Y-%m') AS month,
model,
SUM(cost_usd) AS total_cost,
SUM(input_tokens + output_tokens) AS total_tokens
FROM api_usage
WHERE date >= '2026-06-01'
GROUP BY month, model
ORDER BY month DESC, total_cost DESC;
Example Results:
| Month | Model | Total Cost ($) | Total Tokens |
|---|---|---|---|
| 2026-06 | GPT-5.6 | 342.50 | 45,200,000 |
| 2026-06 | Claude 4 | 156.80 | 38,100,000 |
| 2026-06 | GPT-4.5 | 89.20 | 12,400,000 |
| 2026-05 | GPT-5.6 | 298.30 | 41,800,000 |
💡 Cost Optimization Tip: Use GPT-4.5 for simple tasks, switch to GPT-5.6 for complex reasoning. You can save 30-40% monthly.
