Kiln
The easiest tool for fine-tuning LLM models, synthetic data generation, and collaborating on datasets.
Project mention: Show HN: Create your own finetuned AI model using Google Sheets | news.ycombinator.com | 2025-04-30What’s the thinking of spreadsheet first? Just making it super accessible for people who already have data?
I’m building a UI for fine tuning (and evals, and synthetic data gen) - https://github.com/Kiln-AI/Kiln - and went the custom UI route. From chatting with folks - most people don’t have datasets, and need help building them.

intellagent
A framework for comprehensive diagnosis and optimization of agents using simulated, realistic synthetic interactions
Project mention: Making Sure AI Agents Play Nice: A Look at How We Evaluate Them | dev.to | 2025-05-01When it comes to evaluating conversational agents, there are some smart ways to do it. Take a framework like IntellAgent. It uses AI to test other AI! It's a three-step process designed to make testing more thorough and realistic than just having a person manually try things out.

MOSTLY AI has open-sourced its powerful Synthetic Data SDK, enabling you to create privacy-preserving, AI-generated synthetic data directly from your existing datasets—all within your secure environments.
Key Features:
Broad Data Support: Handle mixed data types (categorical, numerical, geospatial, text), single/multi-table datasets & time-series data.
Multiple Model Types: Leverage TabularARGN (SOTA for tabular data), fine-tuned HuggingFace models, and efficient LSTM for text generation.
Advanced Training Options: CPU/GPU support, differential privacy, and real-time progress monitoring.
Automated Quality Assurance: Built-in fidelity & privacy metrics with detailed HTML reports for visual data analysis.
Flexible Sampling: Upsample data, generate conditionally, rebalance segments, impute context-aware values, ensure fairness, and control outputs via temperature adjustments.
Seamless Integration: Connect effortlessly to external databases & cloud storage with a fully permissive open-source license.
