Before you change production

This page includes public source URLs in the imported troubleshooting record. Compare those references with your version and environment before applying changes.

Reproduce the smallest failing action and save non-secret logs before changing configuration.
Check versions for LiteLLM, related SDKs, package managers, CI runners, and hosting providers.
Change one setting or dependency at a time, then rerun the same failing command or request.
Avoid destructive commands, credential rotation, billing changes, or security relaxations without a rollback plan.

What this error means

Deployment-level TPM limit enforced per-pod, not cross-pod — effective limit = tpm_limit × N_replicas is a LiteLLM failure pattern reported for developers trying to fix litellm deployment-level tpm rate limit being enforced per-pod instead of across all replicas in multi-replica kubernetes deployments. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

In multi-replica LiteLLM proxy with usage-based-routing-v2, deployment-level TPM limit (litellm_params.tpm in model_list) is enforced against each replica's local in-memory counter. Effective per-deployment ceiling becomes tpm_limit × N_replica. Traffic up to that inflated ceiling passes without rate limiting.

Common causes

Enterprise LiteLLM deployments on Kubernetes rely on deployment-level TPM limits to control costs. When limits are per-pod instead of cross-pod, the effective rate limit scales with replica count, defeating cost controls and potentially causing unexpected API overages.

Quick fixes

Confirm the exact error signature matches Deployment-level TPM limit enforced per-pod, not cross-pod — effective limit = tpm_limit × N_replicas.
Check the LiteLLM account, local tool state, and provider configuration involved in the failing workflow.
Reduce request pressure, check quota or plan limits, and retry with backoff instead of immediate repeated requests.

Platform/tool-specific checks

Verify the command, editor, extension, or API client that produced the error.
Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
Avoid deleting credentials, local model data, or project settings until the failing scope is clear.

Step-by-step troubleshooting

Capture the exact error message and the command, editor action, or request that triggered it.
Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
Review the source evidence below and compare it with your environment.
Apply one change at a time and rerun the smallest failing action.
Keep the working fix documented for the team or deployment environment.

How to prevent it

Keep provider/tool configuration documented.
Record non-secret diagnostics such as tool version, provider name, model name, and command path.
Add a lightweight check before CI or production workflows depend on the tool.

FAQ

What does Deployment-level TPM limit enforced per-pod, not cross-pod — effective limit = tpm_limit × N_replicas mean in LiteLLM?

Deployment-level TPM limit enforced per-pod, not cross-pod — effective limit = tpm_limit × N_replicas indicates the workflow described by "LiteLLM Multi-Replica Deployments Bypass TPM Limits — Per-Pod Enforcement Instead of Cross-Pod" failed in a LiteLLM context. Start by confirming the exact signature and the component that emitted it.

What should I check first for Deployment-level TPM limit enforced per-pod, not cross-pod — effective limit = tpm_limit × N_replicas?

Check whether this cause matches your environment: Enterprise LiteLLM deployments on Kubernetes rely on deployment-level TPM limits to control costs. When limits are per-pod instead of cross-pod, the effective rate limit scales with replica count, defeating cost controls and potentially causing unexpected API overages.

Is the Deployment-level TPM limit enforced per-pod, not cross-pod — effective limit = tpm_limit × N_replicas guidance source-backed?

The "LiteLLM Multi-Replica Deployments Bypass TPM Limits — Per-Pod Enforcement Instead of Cross-Pod" page is labeled source-backed. It has 1 public source URL from github.com, so use that evidence status when deciding how much additional verification you need.

When should I avoid the quick fix for Deployment-level TPM limit enforced per-pod, not cross-pod — effective limit = tpm_limit × N_replicas?

For "LiteLLM Multi-Replica Deployments Bypass TPM Limits — Per-Pod Enforcement Instead of Cross-Pod", avoid applying "Reduce request pressure, check quota or plan limits, and retry with backoff instead of immediate repeated requests." when the error text differs, the affected version or provider is different, or the change would touch credentials, billing, DNS, production deploy settings, or irreversible data.

What should I collect before debugging Deployment-level TPM limit enforced per-pod, not cross-pod — effective limit = tpm_limit × N_replicas?

For "LiteLLM Multi-Replica Deployments Bypass TPM Limits — Per-Pod Enforcement Instead of Cross-Pod", collect the failing LiteLLM command or request, non-secret configuration, versions, timestamps, request IDs when available, and the smallest reproduction that still triggers the signature.
