LLMs weren't built for classification.
Nyckel was.

LLMs are great for genAI, but imperfect for classification. Nyckel is the AI alternative built specifically to solve classification problems.

"We tried not-great options like LLMs for classification, then found Nyckel. They're the perfect fit for classification."

— CEO, Retailhub

If you want high accuracy, custom-built models will always outperform general purpose LLMs

Achieving production-ready accuracy involves training the model on your own data. Doing that with Nyckel takes just seconds.

LLMs can't provide accurate confidence scores

Confidence scores play a pivotal part in understanding the classification result. Only discriminative AI tools like Nyckel can provide confidences scores accurately. Learn more on our blog.

Without a UI, fine-tuning is prone to errors and wasted time

LLMs with fine-tuning tools don't come with a UI for easy data management. Meanwhile, Nyckel's UI lets anyone on the team see uploaded samples and make tweaks on the fly.

Counting tokens and tweaking prompts is time-intensive.

Alternatively, Nyckel provides prompt-free API endpoints that charge only for # of classifications.

Unlike LLMs like ChatGPT's 4o, Nyckel offers discounts as you scale.

No data? No problem.

Nyckel offers 100s of pretrained classifiers you can access immediately - or clone and improve upon yourself!

How it works

Nyckel is an AI platform build specifically for classification

Connects with 100+
Deep Neural Networks

Ensures these models have high accuracy.

Streamlines data
processing for you

Your models can train with a few as 2 samples per class.

Scales from day 1
thanks to elastic requests

Pay only for what you use - not for idle GPU time.

Classification problems deserve a classification solution, not an LLM.

	LLMs
Accuracy	Decent accuracy from a basic prompt. Plateaus without training.	The ability to train on custom samples means constant improvement over time.
Confidence scores	GenAI wasn't built to return trustworthy confidence scores.	Nyckel was built to provide scores you can trust.
Fine-tuning	You have to upload a new file with all the old samples.	You can add new samples without worrying about what was already uploaded.
UI Management	Once you upload samples, there's no easy way to see or fix annotations.	Nyckel's UI provides clear visibility into every uploaded sample.
Deployment	Manual. Involves an engineer uploading the new folder.	Automatic. Anyone can add a new sample and annotate, and the model auto-redeploys.
