For clarifai infrastructure and model engineering teams

Clarifai model deployment failed: build, events or runtime?

Compare the deployment events with the first model-worker exception. A failed build, unavailable deployment and failed prediction should not receive the same GPU remedy.

Start your free 30-day Team evaluation

Up to 50 diagnoses a day for 30 days. Verify your work email to activate an eligible company evaluation, then replay a resolved incident and compare the evidence and next steps with your team's confirmed cause.

Use your company email (e.g. alex@yourcompany.com). Eligible company domains can activate a free 30-day Team evaluation (up to 50 diagnoses/day) after email and domain checks, regardless of mail host. Uncertain domains can request review from support@denpex.com. Free local diagnoses remain available without an account.

What a useful evaluation should establish

Compare the first failure, quoted evidence and unresolved questions with an incident your team has already resolved. Begin with this question: Did the model reach an inference worker? Only attribute a process, rank, device or recovery state when the submitted evidence establishes it.

Did the model reach an inference worker?

Evidence to compare: Build result, deployment identity and event-log timestamps.

A packaging or deployment failure can prevent execution entirely. Establish that a worker started before interpreting a client error as a model-runtime failure.

Which exception preceded the failed request?

Evidence to compare: Worker initialization output and the first retained traceback.

The final client response may hide a loading or dependency failure. Trace it to a specific worker phase; missing backend evidence remains a question.

Can the next owner reproduce the comparison?

Evidence to compare: Model revision, container version and a redacted confirmed incident outcome.

A useful handoff identifies the same deployment across layers and preserves the known resolution. Do not upload credentials or proprietary model artifacts.

Use Denpex alongside your existing telemetry tools to investigate submitted incident evidence. With monitoring configured on a supported plan, detected failures can trigger alerts and an automatic diagnosis from the captured evidence.

Inside Denpex

See the evidence, not just the claim

Follow the causal chain, inspect the quoted evidence and prepare the next handoff. These actual product captures use founder-account examples and the VS Code extension, with the source identified under each image. Open a capture to inspect it at full size.

Follow the failure through the cascade

Denpex founder-account example: a causal graph connects an Xid 48 ECC event to a rank exit and downstream collective failures, with quoted evidence for each stage.
Live founder-account capture from the bundled NCCL/ECC example. Follow the hardware event, rank exit and downstream symptoms with a supporting log quote at each stage.Inspect original image

Prepare the hardware escalation

Denpex hardware handoff summary asks the operator to capture diagnostic evidence and verify RMA eligibility with the vendor.

Ask for the evidence that is missing

Denpex historical example says a collective timeout does not establish the initiating rank, cause or failure domain and requests distinguishing evidence before a remedy.

Keep the investigation in the editor
