A pretrained tiger species classifier that sorts an image into one of 2 categories — which species of tiger it is. Use the tiger species API immediately, no training required, then adapt it to your own data when you need more.
Drop in a photo and get the prediction back. No signup, no setup.
A sample of the 10 labels this pretrained classifier chooses between.
Need a label that isn't here? Clone the classifier into your Nyckel console and edit the label set to fit your data.
Once you've added this classifier to your console, you get your own copy of it behind your own endpoint. Invoke it with any HTTP client:
curl
curl -X POST "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke" \
-H "Authorization: Bearer $NYCKEL_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{"data": "https://example.com/photo.jpg"}'Python
import requests

}Trained on a Nyckel-curated dataset covering 2 tiger 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.
Conservation organizations could use the 'tiger species' identifier function to classify tigers within provided images. This helps monitor species numbers, locations, and overall impact of conservation efforts.
Zoos and research institutions could utilize this function to effectively categorize images of different tiger species for study purposes, contributing to the overall knowledge about these animals' behaviour, characteristics, and habitats.
Law enforcement authorities could utilize this function to identify specific tiger species in confiscated media content during illegal wildlife trade investigations, assisting them in tracking the source, destinations, and trends of this illegal market.
Safari parks could use the function to correctly label images of various tiger species within their parks. This can update stakeholders, like tourists and scientists, about park's biodiversity and individual animal identification.
Educational institutions and content creators can use this function to accurately label tiger species in images. This aids in creating factual, informative pieces for students and learning platforms.
News outlets and journalists covering wildlife or environmental stories can use this function to accurately identify tiger species within their reportage. This ensures the accuracy of the information being communicated to the public.
Ecotourism companies and wildlife photographers could use the 'tiger species' identifier to accurately label and categorize their photographs, enhancing their catalog's usefulness, and offering additional value to clients or viewers interested in specific tiger species.
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.
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.
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.
No. This tiger 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.
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.
Add this pretrained classifier to your Nyckel console — you'll get a live API endpoint in under a minute, and a path to a custom model when you need one.
