A pretrained eye alignment classifier that sorts an image into one of 10 categories — the alignment of a person's eyes. Use the eye alignment 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 15 labels this pretrained classifier chooses between.

}Trained on a Nyckel-curated dataset covering 10 eye alignment 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.
The eye alignment identifier can assist healthcare professionals in diagnosing conditions related to eye alignment, such as strabismus or amblyopia, remotely through telemedicine platforms. This would enable quick assessments and targeted treatment plans for patients without the need for in-person visits.
In augmented reality (AR) applications, the eye alignment identifier can enhance user experience by ensuring that virtual objects are correctly aligned with the user’s line of sight. This technology can lead to more immersive and realistic experiences in gaming, education, and training simulations.
Optical devices, such as cameras and microscopes, can use eye alignment identification to optimize focus and improve image capture under various conditions. This application can be particularly useful in fields like photography, medical imaging, and scientific research, where precision is essential.
The eye alignment identifier can monitor patient progress in vision therapy by providing objective data on eye positions over time. This information can help practitioners adapt therapy methods more effectively based on real-time analysis, leading to better outcomes for patients.
In manufacturing environments where visual inspection is critical, the eye alignment identifier can ensure that products meet alignment specifications before packaging. This can improve quality assurance processes and reduce the rate of returns due to misaligned products.
Eye alignment identification can be integrated into advanced driver assistance systems (ADAS) to ensure that drivers maintain proper focus and attention on the road. This feature can provide alerts or engage corrective measures if signs of distraction or misalignment are detected, enhancing overall safety.
In the realm of sports, the eye alignment identifier can be used to analyze athletes' visual focus and attention during training. By understanding eye alignment in relation to movement and technique, coaches can offer personalized feedback to optimize performance and reduce the risk of injuries.
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 eye alignment 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.
