KoG Playground is an open-source, browser-based platform designed to simplify the development of retrieval-augmented generation (RAG) agents. It connects to popular vector stores like Pinecone or FAISS, allowing users to ingest text corpora, compute embeddings, and configure retrieval pipelines visually. The interface offers modular components to define prompt templates, LLM backends (OpenAI, Hugging Face), and chain handlers. Real-time logs display token usage and latency metrics for each API call, helping optimize performance and cost. Users can adjust similarity thresholds, re-ranking algorithms, and result fusion strategies on the fly, then export their configuration as code snippets or reproducible projects. KoG Playground streamlines prototyping for knowledge-driven chatbots, semantic search applications, and custom AI assistants with minimal coding overhead.

Python AGNO Memory Agent provides a structured approach to agent memory by organizing memories via an AGNO framework. It leverages embedding models to convert textual memories into vector representations and stores them in configurable vector stores like ChromaDB, FAISS, or SQLite. Agents can add new memories, query relevant past events, update outdated entries, or delete irrelevant data. The library offers timeline tracking, namespaced memory stores for multi-agent scenarios, and customizable similarity thresholds. It integrates easily with popular LLM frameworks and can be extended with custom embedding models to suit diverse AI agent applications.
