Replicate is the go-to platform for developers who need to run open-source AI models (Stable Diffusion, Llama, Whisper, SDXL) without managing their own GPU infrastructure. When Replicate predictions start failing — whether from platform outages, model failures, or cold start timeouts — the first question is: is Replicate down, or is it a specific model issue?
Platform vs Model: The Key Distinction
Unlike single-service APIs, Replicate hosts thousands of models. An issue might affect the entire platform, or just a specific model version. This distinction determines your troubleshooting path:
🔴 Platform-Wide Issue
- • Multiple different models all failing
- • API returns 5xx errors on list endpoints
- • Replicate web app inaccessible
- • status.replicate.com shows active incident
⚠️ Model-Specific Issue
- • Only one model is failing
- • Other models run successfully
- • Prediction error field has specific message
- • Replicate status page is green
How to Check if Replicate is Down (4 Methods)
1. Replicate's Official Status Page
Visit status.replicate.com for real-time status across the Replicate API, prediction runner, web app, and training infrastructure. This distinguishes platform outages from model-specific failures.
2. Test a Minimal API Call
Call GET https://api.replicate.com/v1/models with your auth token. If this returns 200, the API is up — the issue is model-specific. If it returns 5xx, it's a platform issue.
3. Try a Different Model
If one model is failing, test a completely different one (e.g., if SDXL is failing, try Whisper). If the second model works, the issue is model-specific — check that model's version page for known issues.

Common Replicate Errors and Fixes
401 UnauthorizedInvalid or missing API tokenFix: Check your Authorization: Token header. Verify at replicate.com/account/api-tokens.
404 Not FoundModel or version doesn't existFix: Verify model owner/name format (e.g., "stability-ai/sdxl"). Check if version hash is correct.
422 Unprocessable EntityInvalid input parametersFix: Check the model's input schema on its Replicate page. Verify required fields and types.
429 Too Many RequestsRate limit exceededFix: Implement backoff. Check your account limits at replicate.com/account/billing.
prediction.status = "failed"Model-specific inference errorFix: Check prediction.error field for details. Try a different model version or reduce input complexity.
Cold start timeoutModel took too long to bootFix: Set up a Replicate Deployment for your critical models — this keeps replicas warm and eliminates cold starts.
Why Does Replicate Go Down?
- GPU Capacity Constraints: Replicate sources GPU capacity across cloud providers. During AI usage spikes, GPU availability can be exhausted, causing prediction queue saturation.
- Cold Start Cascades: Popular models that haven't been run recently need to boot on fresh hardware — during demand spikes, thousands of cold starts simultaneously can overwhelm the orchestration layer.
- Model Version Deprecation: When model owners push breaking changes or delete versions, existing integrations can silently fail — this appears like downtime but is model-specific.
- Training Queue Saturation: Heavy use of the Training API can compete with the Prediction API for GPU resources during peak periods.
Action Plan: What to Do When Replicate is Down
Immediate Steps:
- Check status.replicate.com to distinguish platform vs model issue.
- Check the prediction response's
errorfield for model-specific messages. - Try the same model via a different version hash.
- Follow @replicate on X for official incident updates.
For Production Applications:
- Use Replicate Deployments for critical models — dedicated compute eliminates cold starts and prioritizes your traffic.
- Implement fallback to alternative inference platforms: Together AI, Modal, or Hugging Face Inference API for open models.
- Set up Alert Pro monitoring with automatic webhook triggers when Replicate prediction success rate drops.
- Cache model outputs where possible — many Replicate use cases (image generation for given prompts) are idempotent.

Is Replicate down for everyone or just me?
If status.replicate.com shows green but you're getting errors, test a different model to determine if it's platform-wide or model-specific. A 5xx from the /v1/models list endpoint confirms a platform-wide issue.
Why is my Replicate prediction stuck in "starting" state?
"Starting" means the model is cold-booting on a fresh GPU instance. For free-tier models, this can take 30 seconds to 5 minutes depending on model size. If it exceeds 10 minutes, cancel and retry. Use Replicate Deployments to eliminate cold starts entirely.
How long do Replicate outages typically last?
Platform-wide Replicate outages are uncommon and typically resolve in 1-3 hours. Model-specific failures may require a model owner to push a fix — resolution time varies. Check status.replicate.com for active incident timelines.
What are Replicate Deployments and should I use them?
Replicate Deployments provide dedicated compute for your models — your traffic gets its own GPU pool instead of sharing the public queue. This eliminates cold starts and ensures your production workloads aren't affected by community traffic spikes. Recommended for any app with real users.
Can I self-host Replicate models to avoid platform downtime?
Yes. Most models on Replicate are open-weight and can be self-hosted using Cog (Replicate's open-source tool). For maximum reliability, consider running critical models on your own infrastructure via Cog + your cloud provider, with Replicate as a fallback.
