    Grounded Docs

    Grounded Docs

    Open-Source Alternative to Context7, Nia, and Ref.Tools

    Grounded Docs is an open-source implementation of a Model Context Protocol server designed to expose documentation and structured information as tools that AI agents can query. The project allows language models and agent frameworks to retrieve and interact with documentation through standardized MCP interfaces. By acting as an intermediary layer between documentation sources and AI tools, the server enables models to access structured documentation in a consistent and machine-readable format. This makes it easier for AI systems to answer technical questions, generate code examples, or retrieve reference material without requiring developers to manually integrate documentation into prompts. ...

    RAPTOR

    RAPTOR

    The official implementation of RAPTOR

    ...Each level of the tree represents summaries at different levels of abstraction, allowing retrieval to operate at both detailed and high-level conceptual layers. During inference, the system can navigate this hierarchical representation to retrieve information that best matches the user’s query while preserving broader contextual understanding. This approach improves question-answering performance on complex tasks that require reasoning across long documents or multiple sources.

    Playwriter

    Playwriter

    Chrome extension to let agents control your browser

    ...The system enables browser automation by running Playwright commands through a persistent session managed by a background extension, allowing agents or scripts to navigate, interact with, and query browser contexts without losing state between commands. This makes it valuable for scenarios where AI agents need to perform complex web automation tasks—like multi-step navigation, form interaction, or content extraction—without reinitializing context or state every time. Playwriter’s architecture supports both extension-based control for real browser windows and CLI integration, giving developers flexibility in how they build and run browser automation workflows.

    Qwen3-VL-Embedding

    Qwen3-VL-Embedding

    Multimodal embedding and reranking models built on Qwen3-VL

    ...The core embedding model maps such inputs into semantically rich vectors in a unified representation space, enabling similarity search, clustering, and cross-modal retrieval. The reranking model then precisely scores relevance between a given query and candidate documents, enhancing retrieval accuracy in complex multimodal tasks. Together, they support advanced information retrieval workflows such as image-text search, visual question answering (VQA), and video-text matching, while providing out-of-the-box support for more than 30 languages.

    Mixed-effects models in Julia

    Mixed-effects models in Julia

    A Julia package for fitting (statistical) mixed-effects models

    This package defines linear mixed models (LinearMixedModel) and generalized linear mixed models (GeneralizedLinearMixedModel). Users can use the abstraction for statistical model API to build, fit (fit/fit!), and query the fitted models. A mixed-effects model is a statistical model for a response variable as a function of one or more covariates. For a categorical covariate the coefficients associated with the levels of the covariate are sometimes called effects, as in "the effect of using Treatment 1 versus the placebo". If the potential levels of the covariate are fixed and reproducible, e.g. the levels for Sex could be "F" and "M", they are modeled with fixed-effects parameters. ...

    ...Lighthouse leverages your existing models and creates optimized database queries out of the box. Define your schema without any boilerplate by using the GraphQL Schema Definition Language. In a GraphQL query, the client can get all the data they need - and no more - all in a single request. A GraphQL server can tell clients about its schema, so they will always know exactly what they will get. Updating between minor versions will not require changes to PHP code or the GraphQL schema and cause no breaking behavioural changes for consumers of the GraphQL API.

    Ristretto

    A high performance memory-bound Go cache

    ...We then repurposed Groupcache’s LRU, using mutex locks for thread safety. After having it around for a year, we noticed that the cache suffered from severe contention. A commit to remove that cache caused our query latency to dramatically improve by 5-10x. In essence, our cache was slowing us down! We concluded that the concurrent cache story in Go is broken and must be fixed. In March, we wrote about the State of Caching in Go, mentioning the problem of databases and systems requiring a smart memory-bound cache which can scale to the multi-threaded environment Go programs find themselves in.
