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

What this fly species classifier recognizes
A sample of the 18 labels this pretrained classifier chooses between.

}Under the hood
Trained on a Nyckel-curated dataset covering 2 fly 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 fly species classification
Pest Control Services
Pest control companies can use the 'fly species' identifier to quickly and accurately identify the specific species of flies infesting an area, helping them determine the most effective treatment method.
Medical Research
In the medical field, certain species of flies are known for carrying diseases. With the 'fly species' identifier, researchers can classify specific species in different regions and study their epidemiological implications.
Agriculture Management
Farmers and agricultural businesses can use the 'fly species' identifier to identify harmful fly species for their crops or livestock, enabling them to implement appropriate pest management strategies.
Environmental Research
Scientists studying ecosystems or biodiversity can use the 'fly species' identifier to accurately record the presence and distribution of fly species in various habitats.
Public Health Organizations
Public health organizations can use this system to keep an eye on the prevalence of potentially disease-carrying fly species in populated areas.
Food Industry
The 'fly species' identifier can be used in the food industry to recognize and manage fly species that could potentially contaminate food products, thereby preventing foodborne illnesses.
Biodiversity Preservation
Conservation organizations can use the 'fly species' identifier to monitor the presence and numbers of specific fly species, tracking changes in population and extinction risks.
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 fly 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.
