Pretrained text classifier

Identify seat availability with one API call.

A pretrained seat availability classifier that sorts text into one of 2 categories. Use the seat availability API immediately, no training required, then adapt it to your own data when you need more.

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 2 seat availability categories, served on Nyckel's own infrastructure — your text snippet stays on Nyckel.

Input
Text

Send raw text to the invoke endpoint; the response is a label with a confidence score.

Make it yours
Adaptable

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.

More than a demo: this page is one of thousands of pretrained functions on Nyckel, an ML classification platform. You can invoke classifiers by API, review predictions, correct labels, collect samples from production traffic, and promote any pretrained function to a private custom model — without changing your integration.

Where teams use seat availability classification

Airline Reservation System

The seat availability identifier can be integrated into an airline's reservation system to automatically classify whether a specific flight has available seats. This can enhance customer experience by providing real-time updates on seat status during the booking process.

Event Ticketing Platform

For event organizers and ticketing platforms, this function can categorize the availability of seats in venues for various types of events like concerts and sports. By accurately reflecting seat status, it can help maximize sales and minimize customer frustration over sold-out events.

Ride-Sharing Services

The identifier can be used in ride-sharing applications to classify whether seats in vehicles are available based on passenger requests. This enables drivers to efficiently manage their capacity and optimize the booking process for passengers.

Public Transportation Apps

By integrating the seat availability identifier into public transportation apps, users can find out whether seats are available on buses and trains in real-time. This feature can help commuters make informed decisions about their travel plans, especially during peak hours.

Hotel and Hospitality Booking

This function can help hotels identify whether specific types of accommodations that include seating, such as suites or lounges, are available. This allows hotel staff to provide guests with accurate information during the booking process, enhancing customer satisfaction.

Conference and Meeting Room Management

The identifier can aid businesses in managing seating in conference rooms or meeting spaces. By classifying the availability of seating arrangements, it can streamline the scheduling process for events and reduce overcrowding in corporate settings.

Vehicle Fleet Management

Fleet management systems can use the seat availability identifier to monitor the availability of seats across various vehicles in a company’s fleet. This enables more efficient allocation of vehicles based on demand, ensuring that passenger transportation needs are met without overloading capacities.

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 text samples 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 seat availability 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.
