Tembo gives your workspace a dollar-denominated usage allowance. Tembo-managed model inference and cloud VM compute draw from the same balance.

​
Plans

  • Free: $10 one-time usage allowance, up to 3 users, sandbox size up to micro
  • Pro ($60/month): $60 monthly usage allowance, up to 5 users, sandbox size up to medium, with overage billing
  • Max ($200/month): $200 monthly usage allowance, up to 10 users, sandbox size up to xl, with overage billing
Pro and Max can use overage billing so your work can continue after you use your monthly allowance and prepaid balance. You can set a maximum overage limit to control spend. On Free, new sessions are blocked when the allowance and prepaid balance are exhausted until you upgrade or add funds. BYOK (Bring Your Own Key) is available on Pro, Max, and Enterprise.

​
How the usage allowance works

Two usage categories draw from the same balance:
  • Managed inference: model input, output, and cache usage is charged at the rates in Usage Pricing.
  • Cloud VM compute: metered from the CPU, memory, and runtime used by each session.
BYOK and ChatGPT/Codex OAuth inference cost $0 through Tembo because you provide the model access. The cloud VM running the session continues to draw from your usage allowance. Included monthly allowance expires at the end of each billing cycle and does not roll over. Prepaid balance does not expire.

​
Cloud VM compute rates

VM compute is a separate usage category from managed inference. It draws from the same dollar-denominated allowance at $0.0403/vCPU-hour + $0.0130/GiB-RAM-hour. The per-size hourly prices below apply those resource rates to each VM configuration.
Don’t see the VM size you want? Larger VM sizes are available upon request. Contact support@tembo.io to discuss your requirements.
Tembo measures each running VM in seconds and bills its actual running time at the per-second equivalent of the hourly rate. Stopped, snapshotted, and otherwise non-running VMs do not accrue compute. See Sandboxes for more about the execution environment and Usage Pricing for managed inference rates.

​
What consumes the allowance

Managed inference and VM compute are metered while Tembo runs work such as:
  • Creating pull requests from assigned issues (Linear, Jira, Slack)
  • Fixing production errors from Sentry
  • Optimizing database queries and indexes
  • Processing pull request feedback through the Feedback Loop

​
When the allowance runs out

What happens when your balance reaches zero depends on your plan and overage setting:
  • Free: new sessions are blocked until you upgrade or add prepaid balance.
  • Pro or Max with overages enabled: sessions continue and are billed as overage after the included allowance and prepaid balance are used, up to the maximum overage limit you set. Once that limit is reached, new sessions are blocked.
  • Pro or Max with overages disabled: new sessions are blocked as soon as the included allowance and prepaid balance are exhausted.
When work is blocked, the request is rejected immediately rather than queued. Work that has already started can continue its current session so its compute and inference are accounted for correctly.

​
Usage bursts

Some integrations can create a large batch of work at once — for example, a repository or integration sync, or a token refresh that triggers a backlog of issues. Tembo does not cap or rate-limit how much work an integration enqueues; the batch is processed as worker capacity becomes available, and each resulting session records dollar usage when it runs. The same allowance and overage limits above apply, so a burst cannot spend beyond your available balance plus your overage limit. To absorb large bursts without interruption, enable overages with an appropriate limit.

​
Usage refunds

Managed inference usage may be refunded automatically in some cases:
  • Failed sessions: if Tembo cannot complete a session because of an internal error
  • Duplicate issues: if the same issue is queued more than once
  • Invalid inputs: if a session fails due to missing access or configuration problems

​
Usage and monitoring

You can track managed inference, compute, total usage, VM resource-hours, and daily spend in the Billing dashboard. Overage invoices list managed inference and compute separately.

​
Prepaid balance and on-demand usage

  • Free plan: upgrade to Pro or Max for overages, or add prepaid balance
  • Pro and Max: enable overage billing and set a monthly spend limit
  • Prepaid balance: does not expire
To change plans, open Billing settings.

Troubleshooting

Payment failed: confirm the card is valid and has available funds. Prepaid balance did not appear immediately: billing updates can take a few minutes. Need help? Contact hi@tembo.io.
