Baseten vs Letta
An honest, context-aware comparison. No affiliate links. No paid placements. Just the data that helps you decide.
Baseten
Production-grade model serving for custom and open-source models — autoscaling GPU inference.
Letta
Stateful agent framework (formerly MemGPT) — agents with long-term memory, sleep cycles, and self-editing context.
StackMatch Editorial verdicts
Bylined · No vendor influenceBaseten gives you autoscaling GPU inference for custom or fine-tuned models without managing the underlying infrastructure. The right pick for ML teams shipping their own models to production.
Read full review →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.
Read full review →Side-by-Side Comparison
Objective metrics, no spin.
ML teams shipping custom or fine-tuned models to production who don't want to operate the GPU infrastructure themselves.
Teams using only frontier APIs (you don't need this), or teams committed to in-house Kubernetes for compliance.
Research teams, advanced AI engineers building genuinely long-running agents, anyone implementing the MemGPT pattern in production.
Teams that need a quick agent SDK (use LangChain or CrewAI); applications that don't need persistent agent state.
Both suited for: small, medium, large companies
