How did we select the companies for the comparison?
We used the following criteria to narrow down the platforms on the market and divided the criteria into two categories.
Market presence
1. Crowd size
The size of the network of workers in a company is a fundamental criterion for choosing an RLHF platform. A larger crowd size entails a diverse range of human feedback, enriching the learning process and enhancing the quality of model training.
2. User reviews
User reviews provide insights into the real-world performance and reliability of the platform, reflecting the satisfaction level of its clientele.
Platform capabilities
3. Mobile application availability
In an increasingly mobile world, having a mobile application for the RLHF platform can significantly ease the feedback process and provide a seamless experience for both the developers and human evaluators.
4. API integration
API integration facilitates the smooth interchange of data between the RLHF platform and other systems, ensuring a streamlined workflow and quicker iterations in the learning process.
5. ISO certification
ISO certification reflects a platform’s adherence to international standards of quality and security, which is paramount in dealing with sensitive data and ensuring robust machine learning models.
6. Code of conduct
A well-defined code of conduct ensures ethical practices in data labeling and feedback provision, safeguarding the interests of all stakeholders involved. We considered if all platforms had a detailed code of conduct page on their websites.
