Is DeepSeek down? Live API status

Open-weight chat & reasoning models, OpenAI-compatible

Live DeepSeek API status — chat, reasoning (R1) and platform endpoints checked from your browser against api.deepseek.com and platform.deepseek.com.

DeepSeek API status can be verified live by testing direct connectivity from your browser to api.deepseek.com and platform.deepseek.com. Response codes and latency are checked across api.deepseek.com, platform.deepseek.com and chat.deepseek.com to detect outages, degradation and rate limiting. When chat.deepseek.com or the API encounters high traffic, HTTP 503 or 429 errors may occur, indicating temporary congestion rather than a complete infrastructure outage.

DeepSeek's API requires a bearer token and does not return permissive CORS headers, so browser checks confirm DNS, TCP and TLS reachability only. For live incident + capacity flags, see DeepSeek's official status page embedded below.

About DeepSeek

DeepSeek is a Chinese AI lab whose open-weight and hosted models (DeepSeek-V3, DeepSeek-R1) offer OpenAI-compatible chat and reasoning APIs at a fraction of the cost of GPT-4o. This page probes the public API and console endpoints on every poll to confirm they're reachable from your network.

Common DeepSeek issues

  • Empty tokens / hanging streams

    During peak load DeepSeek can accept the request, open the SSE stream, and then deliver tokens very slowly. Timeouts should be set on the client (30–60s for chat) with a retry.

  • 429 Too Many Requests

    Rate limits are per-key + per-model. Splitting traffic across multiple keys does not help — the limits are account-scoped. Use exponential back-off with jitter.

  • Reasoner returns empty content

    deepseek-reasoner streams its chain-of-thought in reasoning_content before final content. If you only read content, early tokens look empty — that's expected, not an outage.

Background

DeepSeek shipped V2 in mid-2024 at a price point that undercut GPT-4-class models by 10-50x. V3 (December 2024) matched GPT-4o on many benchmarks, and R1 (January 2025) demonstrated that a hosted open-weight reasoning model could rival OpenAI o1 for a small fraction of the cost — briefly moving public markets and reshaping API pricing across the industry.

Frequently asked

What is the difference between chat.deepseek.com and the DeepSeek API?
chat.deepseek.com is the consumer web interface, while api.deepseek.com powers developer integrations. When the web chat shows 'Server is busy', the API often remains accessible via OpenAI-compatible endpoints or third-party providers.
How do I check if DeepSeek R1 or V3 is operational?
Both DeepSeek-V3 (deepseek-chat) and DeepSeek-R1 (deepseek-reasoner) share the api.deepseek.com gateway. You can verify operational status by pinging the /v1/models or /v1/chat/completions endpoints using an active API key.
How can I check if chat.deepseek.com is working?
deepseek.health tests platform and web endpoints directly from your browser, showing immediate connection errors, 5xx server failures, or DNS timeouts.
What should I do if DeepSeek returns 429 or 503 errors?
Implement exponential backoff retries, switch to alternate OpenAI-compatible endpoints like Together AI or Groq, or verify your billing balance in the DeepSeek console.
Is the DeepSeek API down right now?
You can check current DeepSeek API uptime on deepseek.health. The dashboard tests real-time reachability against api.deepseek.com and platform.deepseek.com, verifying chat completion and reasoning endpoints from your client browser.
Why is DeepSeek returning 500 or 503 errors?
DeepSeek 500 or 503 HTTP errors typically indicate server capacity overload, rate limits, or transient infrastructure downtime. Implementing exponential backoff retries or multi-provider fallbacks like Together AI or Groq prevents service interruption.
How can I test DeepSeek API availability in code?
Send an authenticated GET or POST request to https://api.deepseek.com/models or https://api.deepseek.com/v1/chat/completions. A 200 OK HTTP response indicates the API is operational; 429 indicates rate limiting, and 5xx indicates upstream service degradation.
Is DeepSeek down right now?
The dashboard above polls api.deepseek.com and platform.deepseek.com from your browser every 15 seconds. Green dots mean the edge is reachable. For internal capacity or model-specific incidents, check the embedded status.deepseek.com panel.
Why do I keep getting 429s from DeepSeek?
DeepSeek publishes generous rate limits, but hosted capacity is finite. 429s spike during Asia daytime and after new-model launches. Retry with exponential back-off and consider a fallback provider.
Is the API OpenAI-compatible?
Yes. Swap base_url to https://api.deepseek.com and you can reuse the OpenAI SDK for chat and streaming. Function calling and JSON mode are supported on the chat model.
What models are live?
deepseek-chat (the V3 chat model) and deepseek-reasoner (the R1-series reasoning model). Older snapshots are usually deprecated on 30-day notice.

About this check

All data is provided on a best-effort basis with no guarantees about accuracy or availability. This is an unofficial status page and is not affiliated with, endorsed by, or sponsored by DeepSeek.

Checks run client-side from your browser against DeepSeek's public endpoints. Latency reflects your network path, not the server's health alone. See our resources for more on how to read these checks.
