Pretrained computer vision classifier
Identify rabbit species with one API call.
A pretrained rabbit species classifier that sorts an image into one of 2 categories — which species of rabbit it is. Use the rabbit species API immediately, no training required, then adapt it to your own data when you need more.

}Under the hood
Trained on a Nyckel-curated dataset covering 2 rabbit species categories, served on Nyckel's own infrastructure — your image stays on Nyckel.
Send an image URL or file to the invoke endpoint; the response is a label with a confidence score.
Clone it, then correct predictions and add your own samples in the console — Nyckel retrains automatically, turning this into a custom model tuned to your data.
Where teams use rabbit species classification
Pet Shop Assistance
Pet shops can implement this function to help customers accurately identify the exact species of rabbit that they wish to purchase or learn more about. This can help customers make better-informed decisions regarding pet suitability and care.
Wildlife Conservation
Wildlife agencies or organizations can use the 'rabbit species' identifier to track rabbit populations in certain areas. Different rabbit species have varying impact on local flora, hence it can assist in ecological balance.
Rabbit Breeding Programs
This function will provide a new level of precision for breeders, ensuring that mating pairs are correctly matched based on their species. This can enhance breeding program efficiency and ensure the purity of certain breeds.
Veterinary Clinics
Vet clinics or rabbit specialists can use this function to quickly diagnose and treat species-specific health conditions, helping them provide better care and accurate information to pet owners.
Pet Insurance Companies
Pet insurance companies can ensure the accurate pricing of their insurance policies based on the identified rabbit species, as certain species may be more prone to specific health conditions.
Pet Supplies Retail
The function can be used to recommend specific products or foods, adapted to the dietary requirements or lifestyle of specific rabbit species, improving customer satisfaction and sales margin.
Agricultural Pest Control
Farmers or gardeners can apply the function to identify invasive rabbit species causing crop or plant destruction, aiding targeted, species-specific pest control measures to protect agricultural yield.
Common questions
What's the difference between a zero-shot and a Nyckel-trained classifier?
A zero-shot classifier uses a large foundation model's general knowledge to pick between your labels — no task-specific training, so new or edited labels work immediately. A Nyckel-trained classifier has been trained on labeled examples and runs on Nyckel's own infrastructure, which typically makes it faster, cheaper per call, and more accurate on data that resembles its training set. The "Under the hood" section on this page shows which kind this classifier is, and any classifier can be adapted into a trained one by adding your own examples.
How do I know whether this will work for my application?
Honestly: we can't know in advance — it depends on your data stream and how closely it resembles what this classifier has seen. The reliable way to find out is to measure it on your own data: start invoking the classifier with real traffic, or upload and annotate a set of images in the console — make sure they look like your production data, not idealized examples. Nyckel's evaluation metrics then show you exactly how it performs on that data before you rely on it.
What happens when it makes a mistake?
No classifier is perfect, so Nyckel is built around the correction loop: invokes can be captured for review, you confirm or correct predictions in the console, and corrections become training data. Over time the model adapts to your data distribution — accuracy on your traffic improves with use rather than staying fixed.
Do I need training data to get started?
No. This rabbit species classifier works out of the box — clone it into your console and you'll have your own API endpoint in under a minute. Training data only enters the picture when you want to adapt it: your corrected predictions and uploaded samples improve the model, and you can also edit the label set to match your needs.
What does it cost to try?
Trying the classifier on this page is free with no signup. Cloning it requires a free account, and the free tier covers your first API calls each month — see nyckel.com/pricing for current limits and paid tiers.
