Leonardo AI Status: How to Check If Leonardo.AI Is Down Right Now (2026)
Where to find the official Leonardo AI status page, what each component means, and how to diagnose generation failures and API issues in real time.
Is Leonardo AI Down Right Now?
Check the official Leonardo AI status page at status.leonardo.ai for API, generation pipeline, and web app incidents. Also check your token balance — exhausted tokens look identical to an outage from the user side.
Where to Find Leonardo AI Status
Leonardo AI reports status across several channels. Use the right source depending on whether you're a consumer user or API developer:
Monitor your Leonardo AI API independently
Better Stack probes your Leonardo AI API endpoint every 30 seconds — detect failures and latency spikes before they break your image generation integrations.

Leonardo AI has grown from an image generator into a multi-model platform. Understanding which service is failing helps you pinpoint the issue:
Image Generation (Phoenix & Flux)
Leonardo's flagship models. Phoenix is Leonardo's in-house architecture; Flux (Black Forest Labs) is an open-weight model hosted by Leonardo. These are the most-used endpoints and have separate generation queues.
Fine-Tuned & Community Models
Leonardo hosts thousands of fine-tuned models trained by the community. These run on shared GPU pools and can experience capacity issues independently of the flagship model queues.
Motion (Video Generation)
Leonardo's image-to-video feature. More GPU-intensive than image generation and typically has longer queue times.
Canvas Editor & AI Tools
Inpainting, outpainting, and the canvas editor in the web app. These features can degrade separately from the core generation API.
REST API (cloud.leonardo.ai)
The developer-facing API at cloud.leonardo.ai/api/rest/v1/. Developers using this endpoint have separate queue prioritization from web app users on some model tiers.
Common Leonardo AI Errors and What They Mean
| Error / Issue | Meaning | Action |
|---|---|---|
| 401 Unauthorized | Invalid or expired bearer token | Regenerate your API key at app.leonardo.ai/settings/api-key |
| Insufficient tokens / credit | Daily or monthly token balance exhausted — NOT an outage | Check token balance at app.leonardo.ai/profile; upgrade plan or wait for daily refresh |
| Generation stuck in queue | High demand causing long wait times — not necessarily a failure | Wait 5–10 minutes; try a smaller image size or less popular model |
| 429 Too Many Requests | API rate limit exceeded for your plan | Implement backoff; check your plan's requests-per-minute limits |
| 500 Internal Server Error | Backend failure during generation | Retry once; if persistent, check status.leonardo.ai for active incidents |
| NSFW content blocked | Safety filter triggered — not a platform issue | Adjust your prompt; Leonardo's content filters apply to all requests |
| Model not available | Specific fine-tuned model is offline or deleted | Switch to a base model (Phoenix, Flux) which have higher availability guarantees |
| Failed to generate | Ambiguous — could be platform, prompt, or token issue | Check token balance first, then status page, then try with a simple test prompt |
Leonardo AI Troubleshooting: Step-by-Step
Check Your Token Balance First
Navigate to app.leonardo.ai/profile and look at your token balance. Free tier tokens refresh daily at midnight UTC. If your balance is at zero, generation fails silently in a way that looks like a platform outage. This is the most common "Leonardo is broken" scenario.
Check the Official Status Page
Visit status.leonardo.ai for any active incidents. The page lists API availability, generation pipeline health, and web app status separately. Subscribe to incident notifications to get email alerts automatically.
Test the API directly with curl
Run: curl -H "Authorization: Bearer $LEONARDO_KEY" https://cloud.leonardo.ai/api/rest/v1/me. A successful response confirms your API key is valid and the API is reachable. This isolates platform issues from account configuration issues.
Try a different model
If a specific model is failing (community fine-tune, SDXL), switch to Leonardo Phoenix or Flux which have the highest uptime guarantees. POST to /generations with a different modelId to see if the generation succeeds on a different model.
Check the Leonardo Discord
Join the official Leonardo Discord and look at #bugs and #status-updates. Users report issues in real time, and platform engineers often acknowledge incidents there before the status page updates. This is especially useful for generation slowdowns that aren't formally listed as incidents.
Try generating via the web app
If you're an API user experiencing failures, try generating via app.leonardo.ai directly. If web generation succeeds, your API integration may have a configuration issue (wrong model ID, incorrect parameters, authentication problem) rather than a platform outage.
Set up Leonardo AI API monitoring in 5 minutes
Better Stack sends Slack, PagerDuty, or email alerts the moment your Leonardo AI endpoint returns errors — catch outages before they impact your users.

Option 1: Switch to Stability AI API
The Stability AI API (api.stability.ai) offers SD3, SDXL, and Stable Image Core via REST API with a similar interface. It uses a credit system rather than monthly tokens and has independent infrastructure from Leonardo.
Option 2: Use Replicate or Fal.ai
Replicate and Fal.ai host Flux, SDXL, and many other image generation models via their own APIs. They support the same underlying model weights as Leonardo and have well-documented REST APIs compatible with most integration patterns.
Option 3: Run Locally with ComfyUI or AUTOMATIC1111
The Flux and SDXL models Leonardo uses are open-source and freely available on Hugging Face. Running locally with ComfyUI gives you zero dependency on Leonardo's infrastructure — ideal for production pipelines with strict uptime requirements.
Frequently Asked Questions
Where is the official Leonardo AI status page?
Leonardo AI's official status page is at status.leonardo.ai. This tracks the Leonardo.AI web app, REST API (cloud.leonardo.ai/api/rest/v1/), image generation pipeline, and account services. For real-time API health, you can also test the /me endpoint with your bearer token to check API reachability.
Why is Leonardo AI not generating images right now?
Leonardo AI generation failures can stem from: (1) A platform incident — check status.leonardo.ai, (2) Token exhaustion — Leonardo uses a daily/monthly token system; if you run out, generation fails even though the platform is up, (3) Queue congestion — high demand on free tier can cause long generation waits that look like failures, (4) Model-specific issues — fine-tuned or community models can fail while the base Phoenix and Flux models work fine, (5) API authentication — expired or missing bearer token causes 401 errors that aren't platform outages.
Is the Leonardo AI web app down or just the API?
Leonardo AI's web app (app.leonardo.ai) and the REST API (cloud.leonardo.ai) share backend infrastructure but can experience different issues. The web app has its own frontend that can be temporarily broken by a deployment, while the API continues working. To distinguish: try a curl request to the API /me endpoint with your bearer token — if it returns 200, the API is up even if the UI is broken. Check status.leonardo.ai for component-level breakdowns.
How long do Leonardo AI outages typically last?
Most Leonardo AI incidents resolve within 30 minutes to 2 hours. Generation queue slowdowns during peak hours typically self-resolve within 15–30 minutes. Major infrastructure incidents — which are rare — can take 2–4 hours. Leonardo posts updates on status.leonardo.ai and on their official Discord server.
Is Leonardo AI down for everyone or just me?
To determine if Leonardo AI is down globally: (1) Check status.leonardo.ai for active incidents, (2) Test the API directly with a curl GET to cloud.leonardo.ai/api/rest/v1/me with your bearer token, (3) Search 'Leonardo AI down' on X/Twitter for community reports, (4) Check the official Leonardo Discord — the #status-updates and #bugs channels surface issues fast, (5) Try generating a simple image via the web UI — if the UI loads but generation queues indefinitely, check your token balance first.
