There's a free plan; paid tiers are quoted.
Mem0’s Free plan costs $0 per month and is the entry point for building with its memory service. For the first 30 days, it lists 10,000 add requests and 1,000 retrieval requests per month. With your own LLM key, the listed monthly limits rise to 50,000 adds and 10,000 retrievals. Custom is for teams that need tailored volumes and agreement terms. Mem0 also lists usage-based billing with a monthly cap you set, but does not publish per-unit rates.

Add-ons and overages
- Usage-based billing with a monthly cap you set; per-unit rates are not published.
02What the plan grid doesn't tell you
Request volume
Track add and retrieval requests separately. The Free plan’s listed monthly limits differ, and production traffic above them may require a Custom agreement.
LLM key transition
The Free plan uses Mem0 for model calls for 30 days, then your LLM key. Account for your own model-provider charges after that point.
Usage-based billing
Mem0 lists usage-based billing with a monthly cap you set, but per-unit rates are not published. Get the rate card before estimating spend.
Custom overages
Custom overage terms are set in the agreement. Confirm the thresholds, rates and billing treatment for bursts before signing.
03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Side project or evaluation | Free | The $0 plan includes monthly add and retrieval allowances, plus unlimited end users. |
| Startup in production | Custom | Use an agreement when your expected request volume or model-call terms need to be set for your workload. |
| Team with tailored volume | Custom | The agreement sets add and retrieval volumes, model calls and overage terms. |
04Is Mem0 worth the money?
Free is a reasonable starting point for a prototype or low-volume evaluation: it costs $0 and includes unlimited end users, but the request limits and 30-day model-call transition need to fit your workload. For production, model monthly add and retrieval volume separately, and include your own LLM charges after the initial period. Custom is the listed path for tailored volumes and overage terms; ask for the rate card and agreement details before estimating a committed budget. Self-hosting options may also affect total cost, so confirm deployment and infrastructure terms with Mem0.
