Smart Model Router: Let AI Pick the Best Model for Every Prompt
Stop guessing which model to use. Vincony's Smart Model Router analyzes your prompt's complexity, domain, and requirements, then routes it to the optimal model — saving credits and improving quality.
The Model Selection Problem
With 400+ models available, choosing the right one for each task is overwhelming. Use GPT-5 for everything and you're overpaying for simple tasks. Use a cheap model for complex reasoning and you get poor results. The Smart Model Router solves this by automatically matching prompts to the ideal model.
How It Works
The router classifies your prompt across multiple dimensions — task type, complexity, domain, required capabilities — then selects the model with the best performance-to-cost ratio. Simple queries go to fast, cheap models. Complex reasoning goes to frontier models. Code goes to code-specialized models.
import vincony
client = vincony.Client(api_key="YOUR_KEY")
# Let the router pick the best model
response = client.chat.completions.create(
model="auto", # Smart Model Router
messages=[{"role": "user", "content": "Refactor this class to use dependency injection"}],
)
print(f"Model used: {response.model}") # e.g., "codestral"
print(response.choices[0].message.content)Cost Savings
In our tests, Smart Model Router reduced credit usage by 35-50% compared to always using a frontier model, while maintaining equivalent output quality. For teams processing thousands of prompts daily, that translates to significant savings.
Customize Routing Rules
You can set preferences to bias the router toward speed, quality, or cost. You can also exclude specific models or restrict routing to a subset of providers.
response = client.chat.completions.create(
model="auto",
messages=[{"role": "user", "content": "Summarize this quarterly report"}],
routing={
"optimize": "cost", # "quality", "speed", or "cost"
"exclude": ["gpt-5"], # Skip expensive models for simple tasks
"providers": ["anthropic", "mistral"] # Restrict to specific providers
}
