With much of the performance cost being on the prompting to APIs like OpenAI and other LLMs, contextual data retrieval is ideally as fast as possible.\n\n## Features\n\n* 🪄 Modern strategies to stay within the prompt window\n* 💬 Chat session management out of the box\n* 🦜 [Langchain integration](https://python.langchain.com/en/latest/modules/memory/examples/motorhead_memory.html)\n* 🧠 Automatic Embedding generation via OpenAI ADA\n* 🕸️ Redis Vector DB forto utilize RedisSearch (semantic)\n* 💽 Short-term \u0026 long-term storage\n* 🔥 Built in Rust for performance\n\n## Roadmap\n\n* User Authentication\n* Knowledge Graph Memory handling\n* Additional support for other Embedding Models\n* [Create an issue!](https://github.com/getmetal/motorhead/issues)\n\n## Resources\n\n* Check out [Motörhead on Github](https://github.com/getmetal/motorhead)\n* Join the [Motörhead Discord](https://discord.gg/sxbFX5dsQY)\n* Suggest a [feature for Motörhead](https://github.com/getmetal/motorhead/issues)","slug":"IUW-mot-rhead-llm-memory-server-built-in-rust","created_at":"2023-04-20T14:09:32.416Z","updated_at":"2026-05-25T01:01:09.525Z","total_vote_count":19,"url":"https://www.ycombinator.com/launches/IUW-mot-rhead-llm-memory-server-built-in-rust","share_image_url":"//bookface-static.ycombinator.com/assets/ycdc/yc-og-image-c440a0ad1dacfb86eeeb343717479cc54d256614449b4ef719977a0a451f8bc8.png","company":{"id":28183,"name":"Metal","slug":"metal","url":"https://metal.ai/","logo":"https://bookface-images.s3.amazonaws.com/small_logos/0bdcc8475801e999a95ad750970c80614d23f5c4.png","batch":"Winter 2023","industry":"B2B","tags":["Artificial Intelligence","Fintech","SaaS","Finance","Investing"],"search_path":"https://bookface.ycombinator.com/company/28183"}}
