Its premise is flexibility: instead of shipping one rigid annotation tool per task, it provides programmable interfaces and hundreds of ready-made templates so a single deployment can cover computer vision, NLP, documents, audio, time series and multi-modal data. The evaluation side has grown as fast as the labeling side. Label Studio now supports rubric-driven LLM evaluation, side-by-side model comparison, RAG and retrieval grading, RLHF preference collection, and human review of agent traces piped in from observability tools. That makes it a human-in-the-loop workspace for the full lifecycle, from training data to production quality checks. You can run the free Community Edition via pip, Homebrew or Docker on your own infrastructure, or move to Label Studio Enterprise for advanced modalities such as native DICOM reading and LiDAR point clouds, managed services and enterprise support. An API, Python SDK and webhooks connect it to the rest of your stack. **Pricing & Plans:** Label Studio Community Edition is free and open source under HumanSignal. Label Studio Enterprise is quote-based and sold via HumanSignal, adding advanced modalities, managed deployment options and enterprise support. - **All data modalities:** Programmable interfaces and custom templates let one workspace handle images, video, audio, text, PDFs, time series and multi-modal tasks. - **LLM, RAG and agent evaluation:** Build custom benchmarks and rubrics, run side-by-side model comparisons, and grade generated answers against retrieved sources for RAG evaluation. - **RLHF and fine-tuning data:** Collect human preferences, corrections and rankings to feed reinforcement learning from human feedback and fine-tuning workflows. - **ML pipeline integration:** Connect observability tools, storage and any model to power AI-assisted pre-labeling, benchmarking and continuous evaluation. - **Specialist enterprise modalities:** Label Studio Enterprise adds native DICOM handling that preserves windowing and slice geometry, plus LiDAR point clouds with calibrated camera fusion. **Limitations:** The most advanced modalities (native DICOM, LiDAR, many enterprise connectors) are gated behind the paid Enterprise tier; Self-hosting the open-source edition means you own setup, upgrades and scaling; Very flexible configuration can be intimidating for teams that want a fully managed turnkey product [Profile (Markdown)](https://openaitools.app/tool/label-studio.md) ## LanguageGUI LanguageGUI is an open-source design system and UI kit published by Tonki Labs, created by Mauro Sicard and Miguel Joya. It addresses a very specific gap: large language models output text, but products increasingly need to present that text inside rich conversational interfaces. LanguageGUI provides the visual vocabulary for doing that, offering Figma assets that let designers turn plain model responses into structured chat layouts, sidebars, prompt controls and widget-driven screens. The kit is deliberately generous in scope. It contains more than one hundred UI components and customisable screens, ten or more conversational UI widgets, twenty-plus chat bubbles, thirty-plus pre-built screens to start from, several chat sidebars with configurable settings, dedicated multi-prompt workflow screens and eight or more prompt box variants. Everything is built with Figma Auto Layout and organised with variables and styles, so teams can restyle the whole system rather than editing components one by one. A dark mode is included out of the box. The project is free and released under the MIT license, with no upsells or hidden tiers, and can be used in personal or commercial work without attribution. Importantly, LanguageGUI is not a finished product and not a runtime library: it is a design contribution to better conversational AI interfaces. The team tested turning LLM responses into JSON structures that map onto LanguageGUI widgets and render in real time, but chose not to ship a code library for now, leaving implementation to each developer. It was the first of twelve monthly open-source AI projects Tonki Labs planned for 2024. **Pricing & Plans:** Free. LanguageGUI is released under the MIT license with no hidden upsells or paid tiers, and may be used in personal or commercial projects without attribution. - **100+ UI components and screens:** A large library of ready-made building blocks for conversational interfaces, plus screens you can customise to match your product. - **Conversational widgets built in:** Chat bubbles, sidebars with adjustable settings, prompt boxes and dedicated multi-prompt workflow screens cover the core chat patterns. - **Variables, styles and Auto Layout:** Override colors, spacing and typography through Figma variables and styles to match a brand system without rebuilding components. - **Dark mode included:** A pre-designed dark theme is included, so you do not have to rework every screen for dark mode. **Strengths:** Completely free and MIT licensed, with no attribution required; Very broad coverage: 100+ components, 30+ screens and 8+ prompt boxes in one kit; Built with Figma variables, styles and Auto Layout, so theming is straightforward; Dark mode included, saving significant redesign work [Profile (Markdown)](https://openaitools.app/tool/languagegui.md) ## Frequently Asked Questions ### How do Label Studio and LanguageGUI compare in monthly traffic?
