MemGPT) is actively developed. The current source code lives in [`letta-ai/letta-code`](https://github.com/letta-ai/letta-code), which includes the agent harness, interactive terminal UI, App Server, channels, and the runtime used by the desktop and web apps.\n\n> [!NOTE]\n> This repository now serves as a landing page for the Letta project. The retired Letta V1 server source is preserved on the [`archive`](https://github.com/letta-ai/letta/tree/archive) branch for historical reference.\n\n## Get started\n\nInstall Letta from npm:\n\n```bash\nnpm install -g @letta-ai/letta-code\n```\n\nLaunch the interactive terminal UI:\n\n```bash\nletta\n```\n\nRun the App Server for local or self-hosted agents:\n\n```bash\nletta server\n```\n\nYou can also use Letta through:\n\n- the [desktop app](https://docs.letta.com/letta-code/desktop-app) for macOS, Windows, and Linux\n- [chat.letta.com](https://chat.letta.com) in your browser, including on mobile\n- [Slack, Telegram, Discord, and custom channels](https://docs.letta.com/letta-code/channels)\n- the [Letta Agent SDK](https://docs.letta.com/letta-agent-sdk/overview) for building agents into TypeScript applications\n- [Letta Cloud](https://github.com/letta-ai/letta-code#letta-cloud) for keeping agent memory, identity, and conversations available across computers\n\nSee the [`letta-ai/letta-code`](https://github.com/letta-ai/letta-code) README and the [Letta documentation](https://docs.letta.com) for current installation, development, and deployment instructions.\n\n## Historical source\n\nThe [`archive`](https://github.com/letta-ai/letta/tree/archive) branch contains the retired Letta V1 API server as it existed when this repository was archived. Existing tags and releases remain available for reproducibility. That source is unsupported, receives no fixes or security updates, and should not be used in production.","github_created_at":"2023-10-11T07:38:37+00:00","created_at":"2026-07-07T17:32:51.210772+00:00","updated_at":"2026-08-17T00:01:34.892568+00:00","categories":[{"slug":"ai-agents","name":"AI Agents","url":"https://www.graphcanon.com/categories/ai-agents","markdown_url":"https://www.graphcanon.com/categories/ai-agents.md","api_url":"https://www.graphcanon.com/api/graphcanon/categories/ai-agents"}],"tags":[{"slug":"advanced-memory","name":"advanced memory"},{"slug":"agents-development-framework","name":"agents development framework"},{"slug":"self-improving-ai","name":"self-improving ai"},{"slug":"stateful-ai","name":"stateful ai"}],"trust":{"provenance":{"is_fork":false,"github_id":703411624,"owner_type":"Organization","methodology":"github_public_v1","parent_repo":null,"near_duplicate_slugs":[]},"computed_at":"2026-08-17T00:01:34.152Z","maintenance":{"label":"Very active","score":96,"methodology":"github_public_v1","releases_90d":0,"days_since_push":0,"last_release_at":"2026-05-14T17:14:24Z","stars_delta_30d":443,"open_issues_delta_30d":-8},"security_summary":{"status":"no_lockfile","scanner":null,"low_count":0,"high_count":0,"last_scan_at":"2026-07-11T10:59:43.382Z","medium_count":0,"scan_profile":"none","critical_count":0}},"capability_facts":{"scan":{"source":"repo_scan","observed_at":"2026-08-17T00:01:34.620Z"},"license_spdx":{"value":"Apache-2.0","source":"github.license","observed_at":"2026-08-17T00:01:34.620Z"}},"decision_facts":{"hosting":null,"pricing":null,"requirements":null,"constraints":null,"when_to_use":["When you require an AI agent with robust memory features that enable continuous learning and adaptation over time.","In scenarios where the application needs to maintain a state across interactions, allowing the AI to build on previous knowledge."],"when_not_to_use":["If you are looking for a simple stateless AI solution without advanced memory capabilities, as letta is geared towards more complex stateful agent development.","When your project's requirements involve strict limitations around data retention and privacy where even anonymized interaction logs might be considered sensitive."],"source":"enrich:decision_facts","observed_at":"2026-07-11T13:48:49.096Z"},"constraint_facets":null,"decision_summary":[{"label":"Adopt for","value":"letta is a Python-based platform designed to foster the development of stateful AI agents with capabilities for advanced memory techniques that support continuous learning and self-improvement.
