You're overpaying for most AI tasks
You need to sort a support ticket. Detect spam. Route a phone call. Tag a product image. So you:
1
Rewrite "be accurate" 47 ways until the model stops making things up.
2
Catch the 15% of responses that ignore your output format.
3
Watch costs explode when you scale past demo.
It works. But it's slow, expensive, and embarrassingly over-engineered for a task that should take milliseconds.
A dedicated engine for classification at scale
We stripped away the "chat" and let the intelligence focus on: turning messy data into accurate labels.
1
Provide your labels and let the engine auto-calibrate. No "Act as" fluff, no manual tweaking.
2
Pure classification means zero hallucinations. Get the right format, every single time.
3
Scale without the "LLM tax." Built for high-volume apps where speed and margins matter.
It's precise. It's predictable. It's the specialized infrastructure for the 90% of AI tasks that don't need a chat interface.
How we compare to General-Purpose LLMs
Tested on 33 public datasets
Classer beats GPT-5.4-mini on the top classification benchmarks — with zero training data.
Start in 60 seconds. Improve without ML engineers.
1
Just pass your labels. It works out of the box.
2
See every prediction in your console. Inspect confidence scores. Spot edge cases.
3
Add class descriptions. Label a few examples, or let a high-reasoning LLM do it automatically.
4
Enable auto-calibration. The system distills your data into a custom model that lives in your account.
You stay focused on your product. The model gets smarter in the background.
