About
GHOSTMETAL provides browser-based AI chat and an API for applications that use language and image models. It offers GLM-5.3 with a 256K context window, GLM-5.3-long with a 1M context window, and Qwen-3.8 with built-in web search, along with image generation and editing. Its OpenAI-compatible REST API supports streaming and works with clients such as Cursor, Cline, Continue, SillyTavern, Agnai, LangChain, and OpenAI SDKs. The service is intended for individuals and developers using AI for software development, writing, and creative workflows. Customers can use prepaid credits or monthly plans, and manage separate API tokens for individual applications. GHOSTMETAL runs the service on hardware it owns and operates; prompts and responses are processed in memory, while chat history and images remain in the user's browser.

About
LangMem is a lightweight, flexible Python SDK from LangChain that equips AI agents with long-term memory capabilities, enabling them to extract, store, update, and retrieve meaningful information from past interactions to become smarter and more personalized over time. It supports three memory types and offers both hot-path tools for real-time memory management and background consolidation for efficient updates beyond active sessions. Through a storage-agnostic core API, LangMem integrates seamlessly with any backend and offers native compatibility with LangGraph’s long-term memory store, while also allowing type-safe memory consolidation using schemas defined in Pydantic. Developers can incorporate memory tools into agents using simple primitives to enable seamless memory creation, retrieval, and prompt optimization within conversational flows.
