Free tier enough if you only need basic features; pay only if you need advanced capabilities or higher usage limits.
Where it falls short
Performance bottlenecks with large datasets
Kiln is an intuitive app designed for building your own AI models. It offers features like no-code synthetic data generation, fine-tuning, and dataset collaboration, making it a great choice for users who want to quickly build and iterate on AI models. Key Features: 1. No-code Synthetic Data Generation: Kiln allows users to create synthetic data through a simple interface without writing any code, which is very useful for scenarios where data is scarce or difficult to obtain. 2. Fine-tuning: Users...

Kiln is an AI data labeling and model fine-tuning collaboration platform. Sign up on the website.
Visit WebsiteUpload data to label (text, images, conversations), define rules and schema. Supports classification, extraction, RLHF.
Label 20-30 items first as "golden set" to evaluate labeler quality and consistency.
Invite labelers and assign tasks. Kiln supports multi-person labeling with cross-validation and auto consistency calculation.
Arrange third-person arbitration for low-consistency data to ensure training data quality.
Export labeled data in standard formats (JSONL, CSV) for fine-tuning. Kiln integrates with OpenAI, Anthropic fine-tuning APIs.
Use 10% of data as validation set before fine-tuning to assess labeling quality and rework if needed.
Kiln is suitable for scenarios that require quick building and iteration of AI models, such as data scientists fine-tuning models, machine learning engineers collaborating on datasets, and projects that aim to use synthetic data generation to create new models.
