An honest, context-aware comparison. No affiliate links. No paid placements. Just the data that helps you decide.

For most teams: Letta edges ahead on our scoring

Letta

starter
AI Infrastructure

Stateful agent framework (formerly MemGPT) — agents with long-term memory, sleep cycles, and self-editing context.

Open source: free. Letta Cloud: free tier; Pro $20/mo; Enterprise custom.

RunPod

starter
AI Infrastructure

GPU cloud with serverless inference — pay-per-second GPU access from $0.20/hr for community-tier hardware.

Community Cloud: RTX 4090 ~$0.34/hr, A100 ~$1.19/hr. Secure Cloud: ~30% premium. Serverless: per-second GPU billing.

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.

RunPodCAUTIOUS-BUY
The cheapest GPU access on the market — with the caveats that implies

RunPod's Community Cloud gives you RTX 4090s for $0.34/hr and A100s for $1.19/hr — far cheaper than anyone else. Reliability varies; production teams should use Secure Cloud or look elsewhere.

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 RunPod if...

Indie devs, researchers, anyone running batch inference or fine-tuning on a budget; serverless GPU endpoints for inconsistent traffic.

Avoid RunPod if...

Production workloads with strict SLAs (Community Cloud reliability varies); regulated industries needing dedicated hardware.

Both suited for: small, medium companies

Since both tools target small and medium 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.

Still not sure? Describe your situation.

The AI advisor knows both tools and your full stack. Tell it your company size, current tools, and what's not working — it'll tell you which one actually fits.
