在你自己的基礎設施上執行與擴展持久化 AI Agent
為 AI 與資料工作負載打造的无伺服器雲端基礎設施
直接寫 Python，掛載 GPU 或容器，部署成隨流量擴縮、閒置時縮容到零的 HTTPS 端點。
為編碼代理、強化學習 rollout 與不受信任程式碼提供隔離安全環境，啟動低於一秒，可支援百萬級併發沙箱。
在彈性單機或多機 GPU 算力上執行微調、LoRA、全量訓練與強化學習，無需等待配額審批。
透過相容 OpenAI 的端點服務大型語言模型以及影像、影片、音訊模型，也可自帶推論堆疊，由 Modal 負責底層基礎設施。
在你自己的基礎設施上執行與擴展持久化 AI Agent
每個 Actor 都擁有 SQLite 資料庫與檔案系統，Agent 的記憶與進度可在重啟與閒置後保留，無需額外資料庫。
在你自己的基礎設施上執行不受信任或 AI 產生的程式碼，並可細緻控制網路存取、檔案系統權限與資源上限。
節點故障時其 Actor 會帶狀態遷移到其他節點，多步驟工作在崩潰後自動重播，無需自建檢查點機制。
可透過 HTTP 直接定址 Actor 或維持即時 WebSocket 連線，並用 React SDK 讓元件訂閱 Actor 狀態以即時更新。
專項更強專為生成式多媒體模型最佳化的超快速無伺服器執行環境，而非一般的 Python 程式碼。
透過 Cog 可以更輕鬆地封裝模型，但不如 Modal 提供那麼多樣的無伺服器 Python 容器執行方式。
免費 / 開源Mastra is an open-source TypeScript framework for building, deploying, and observing AI agents and workflows. It gives JavaScript developers typed agents, durable workflows, memory, MCP tool support, and built-in observability so prototypes can scale into production.
