LettaEVALUATE
The MemGPT pattern as a real product

Letta (formerly MemGPT) implements the self-editing-context pattern for stateful AI agents in a usable framework. More research-flavored than Mem0; the right pick for teams that want full agent state, not just memory.

Choose Letta if...

Research teams, advanced AI engineers building genuinely long-running agents, anyone implementing the MemGPT pattern in production.

Avoid Letta if...

Teams that need a quick agent SDK (use LangChain or CrewAI); applications that don't need persistent agent state.

Choose Baseten if...

ML teams shipping custom or fine-tuned models to production who don't want to operate the GPU infrastructure themselves.

Avoid Baseten if...

Teams using only frontier APIs (you don't need this), or teams committed to in-house Kubernetes for compliance.

Both suited for: small, medium, large companies

Since both tools target small and medium and large companies, your decision should hinge on the specific use case above rather than company fit. Try the AI Advisor to get a recommendation tailored to your exact stack.
