CONTINUUM vs letta
CONTINUUM: CONTINUUM provides verifiable semantic recovery for long-running AI agents, preventing work duplication and token waste during crashes. It achieves this through compact semantic checkpoints, independent environment revalidation, and a provenance-aware state tracking system.; letta: Letta is a powerful platform for building stateful AI agents equipped with advanced memory, enabling them to learn and self-improve over time. It provides both a command-line interface for local agent execution and a comprehensive API with Python and TypeScript SDKs for seamless integration into applications.

TL;DR

Resuming long-running AI agent tasks after crashes without replaying work, saving tokens and preserving decisions.
lettaMemory & Context · ★ 25.2k
When to choose:
- You want a long-lived agent that remembers past work and rewrites its own memory and context over time.
- You want one agent reachable from CLI, desktop, browser, mobile and messaging apps, with subagents, schedules and hooks.
- You want memory you can inspect: the README says context is tracked in git and can sync to your own repository.
When to skip:
- You only need to add memory to an agent you already use through MCP; a small MCP memory server is a lighter fit.
- You rely on older Letta tutorials or the V1 API server: the project restructured, and the V1 server is retired.
- You want everything to work without signing in: Letta Cloud is the default backend and some features need it.

Features
CONTINUUM01Semantic checkpoints: Compact, versioned, inspectable state, not a transcript dump.
02Idempotent action ledger: Refuses duplicate external side effects; surfaces uncertain ones for reconciliation.
03Environment revalidation: Every checkpoint component verified against the current world before resume.
04Tamper-evident log: Hash-chained event log (36 event types) with integrity verification.
05Recovery engine: Seven recovery modes with a deterministic, sealed next-action contract.

Use Cases
CONTINUUM↳Resuming long-running AI agent tasks after crashes without replaying work, saving tokens and preserving decisions.
↳Wiring a coding agent (e.g., Claude Code, Gemini CLI) to capture file writes as hash-chained evidence and refuse duplicate side effects.
↳Integrating with various LLM frameworks (LangChain, LangGraph, OpenAI Agents SDK) to add robust persistence and verifiable recovery capabilities.
↳Ensuring the integrity and provenance of agent actions and state through a tamper-evident event log.
letta↳Running AI agents locally in your terminal for coding and general tasks.
↳Integrating stateful AI agents into custom applications using the API and SDKs.
↳Developing self-improving AI systems that adapt and learn continually.
