There's a free plan; paid tiers are quoted.
Mem0 starts at $0 per month on Free, but the allowance changes after the first 30 days and depends on whether you bring your own LLM key. The pricing page lists 10,000 add requests and 1,000 retrieval requests monthly for the first 30 days; with your key, those rise to 50,000 and 10,000. Custom is quote-based, with volume set in the agreement. Annual pricing and overage rates are not published.
01Every plan, line by line
| Plan | Billed annually | Billed monthly | Built for |
|---|---|---|---|
| Free | — | $0 | Testing memory features |
| Custom | — | Quote | Teams needing custom volume |
Add-ons and overages
- Usage-based overages with a monthly cap you set; per-unit rates not published
- Custom overage costs are set in your agreement
02What the plan grid doesn't tell you
Free-tier limit changes
After the first 30 days, Mem0 model calls end; continued model calls require your LLM key. Request allowances also differ depending on key use.
Unpublished overage rates
Overages are usage-based with a monthly cap you set, but per-unit prices are not published. Custom overage costs are set in your agreement.
Custom quote required
Custom monthly and annual prices are not published, so teams cannot compare total cost from the public plan grid alone.
Annual pricing absent
The pricing page lists no annual price, so there is no published annual discount to compare.
03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Prototyping memory workflows | Free | Free provides bounded add and retrieval requests; first-30-day limits differ from allowances when you use your own LLM key. |
| Teams with custom volume | Custom | The agreement sets add-request and retrieval volume, model calls, and overage costs; pricing is not published. |
| Apps needing unlimited end users | Custom | Its listed allowance includes unlimited end users, but volume and price are set by agreement. |
04Is Mem0 worth the money?
Mem0 covers core memory infrastructure: extracting, updating, and retrieving persistent context, with compression and governance features also listed. Free gives teams a way to assess the request-based limits, but its allowance changes after 30 days and when using an LLM key. Custom may fit teams that need tailored volume or unlimited end users, yet unpublished prices and overage rates make the total cost hard to judge. It is worth evaluating if persistent memory is a clear need, not on price alone.
