The easiest way to run large language models locally
Run Llama 2 and other models on macOS, with Windows and Linux coming soon. Customize and create your own.
Google's AI and product experiments
Google Labs is an experimental hub where Google publicly tests early-stage AI products and features. It includes projects like AI-powered search enhancements, Workspace integrations (e.g. Gmail and Docs assistants), and generative tools such as NotebookLM.
The scalable, secure alternative to MCP for tool calling
UTCP (Universal Tool Calling Protocol) is an open standard for AI agents to call tools directly, positioned as a lightweight alternative to MCP. It eliminates the "wrapper tax" for lower latency by using a simple JSON manifest to connect to native APIs.
The only way to add AI to your app with zero backend code
Airbolt lets you securely call LLM APIs with zero backend. Just add our client SDK to your app and start making inference calls with best practices built in.
Turn any website into any structured LLM data you want
Supacrawler is a lightweight API for devs to reliably extract clean content from the web. Open source!
Features: Scrape — fetch cleaned content (rendered JS) from a URL. Crawl — follow links to crawl entire sites or sections. Screenshots — capture visual renderings of pages (full page, element, etc). Watch — Monitor website changes. Parse — submit a URL + prompt + a schema (optional) or desired format (JSON, CSV, YAML, MD), and it returns structured data without needing custom scraper logic.
AI file explorer with smart search and local knowledge bases
Filer transforms file management with AI-powered semantic search and intelligent assistants. Search files by content, not names. Create custom AI assistants from your directories using RAG technology. Currently in beta - runs locally for privacy.
Together we Optimize, Measure and Scale
DoCoreAI is an open-source optimization engine that makes AI prompting data-driven instead of trial-and-error. Developers and teams can reduce costs, improve accuracy, and ship faster by dynamically tuning prompts.
With intelligent telemetry + optimization, DoCoreAI helps you track ROI, refine prompts systematically, and unlock reliable AI performance.
Open MLLMs Excelling in Vision, Reasoning & Long Context
Open MLLM family (1B-78B) from OpenGVLab. Excels at vision, reasoning, long context & agents via native multimodal pre-training. Outperforms base LLMs on text tasks.
