How to Use DeepSeek on Janitor AI (2026 Setup)

A working DeepSeek key can still produce a Janitor AI network error if the endpoint, model ID, and key come from different providers. For the direct route, use one DeepSeek account for all three, enter the full chat-completions URL, refresh Janitor AI if needed, and test with a short message before changing generation settings.

Pick one provider route before you create a key

Janitor AI is the chat interface; DeepSeek supplies the model response through an API connection. In this setup, “proxy” means the LLM request route, not an IP proxy or VPN. The broader Janitor AI proxy guide explains that distinction and the security trade-offs.

The important rule is simple: the API key, endpoint, and model name must belong to the same provider route. A DeepSeek key paired with an OpenRouter URL is not a valid direct-DeepSeek setup, even if both services expose OpenAI-compatible APIs.

Direct DeepSeek, AIReiter, or OpenRouter?

This article documents the direct DeepSeek route because it is the easiest one to verify against DeepSeek’s current API documentation. AIReiter is a separate provider route: use an AIReiter key only with its endpoint. If you want the broader meaning of Janitor AI’s proxy fields, see the Janitor AI proxy setup guide.

A community report shows why the error message alone is not enough:

“network error” — u/dailylittlebrat, r/JanitorAI_Official

Treat the phrase as a symptom, not a diagnosis: a provider mismatch, stale model ID, missing balance, or unapplied configuration can produce the same result.

The direct DeepSeek configuration to copy

For a new direct connection, these are the values to start with. DeepSeek’s current quick-start documentation lists https://api.deepseek.com as the OpenAI-compatible base URL and demonstrates the full /chat/completions request endpoint. Use the full request URL when Janitor AI sends requests exactly as entered; if your current connector documents that it appends the path, follow that connector’s base-URL format instead.

Use deepseek-v4-pro when you specifically want the higher-tier model. DeepSeek’s current Models & Pricing page lists Flash below Pro for token pricing, while both are available through the same API family. DeepSeek also lists deepseek-v4-flash-vision-exp, but a Janitor AI text-chat setup should start with Flash or Pro rather than an experimental vision model.

Older tutorials may tell you to enter deepseek-chat or deepseek-reasoner. Use the current V4 IDs from DeepSeek’s live documentation instead of assuming an older alias still resolves.

What you need before opening Janitor AI

1. A DeepSeek Platform account at platform.deepseek.com.
2. A newly created DeepSeek API key.
3. Available account balance. DeepSeek’s error reference maps HTTP 402 to insufficient balance.
4. A character or account setting that permits external proxy use, if your Janitor AI interface exposes that control.
5. A secure place to store the key while you configure the connection.

A consumer login for the DeepSeek chat website is not an API key. Create the key in the developer platform, copy it without extra spaces, and start with a small balance so an exposed key cannot create an unexpected large bill.

Set up DeepSeek in Janitor AI without guessing

The setup is: create the key, enter the endpoint and model, save, refresh if needed, then send a short test.

Create and fund the DeepSeek API account

1. Open DeepSeek Platform.
2. Create or sign in to your developer account.
3. Open the API-key area and create a key for Janitor AI.
4. Copy the key immediately and keep it private.
5. Add enough balance for a small test.

DeepSeek bills API usage by tokens rather than by the number of Janitor AI messages alone. A long character card and a large retained chat history can send many input tokens on every turn, so a small balance is a safer starting point than assuming “DeepSeek” means unlimited free API access.

Add the proxy configuration

1. Open a character chat on Janitor AI.
2. Look for API Settings or the current equivalent in your build.
3. Choose the available Proxy, Custom, or OpenAI-compatible provider control.
4. If the interface offers Add Configuration, create a new entry.
5. Enter DeepSeek Direct as the configuration name.
6. Paste deepseek-v4-flash into the model field.
7. Paste https://api.deepseek.com/chat/completions into the proxy URL field when the field expects a full endpoint.
8. Paste the DeepSeek API key into the key field.
9. Save the configuration and select it as the active route.

Do not use only https://api.deepseek.com when the Janitor AI field expects the final request endpoint. If the current connector documents that it appends /chat/completions, follow that base-URL format instead.

Save, refresh, and send a short test

If the new configuration does not appear to apply, refresh or reopen the Janitor AI tab before testing. Use a short prompt such as “Reply with one sentence confirming the connection.”

A short reply confirms authentication, model resolution, and basic completion, not every character or context setting.

If the test fails, do not immediately change temperature, maximum tokens, or other generation controls. First check the provider route, endpoint, model ID, key, balance, and any proxy-permission setting.

Diagnose the error by the first failing hop

Troubleshooting is faster when you isolate the first system that rejected the request. Check the DeepSeek key and balance first, then the Janitor AI fields, and only afterward investigate browser state or provider availability.

DeepSeek’s official error reference separates authentication (401), balance (402), rate limiting (429), internal failure (500), and server-busy responses (503). That distinction matters: changing an API key will not fix a 429, and changing your IP will not add balance to a 402 account.

Test the same provider values in DeepSeek’s documented quick-start client first to isolate a provider-side failure from a Janitor AI configuration issue; never paste a live key publicly.

DeepSeek on Janitor AI FAQ

Can I use DeepSeek on Janitor AI without an API key?

Not through the direct API route. Janitor AI’s custom proxy connection needs credentials from the provider route you select; a DeepSeek consumer chat account does not replace a DeepSeek Platform API key.

Is DeepSeek free on Janitor AI?

The direct DeepSeek API should be treated as metered API access, not as unlimited free chat. DeepSeek’s pricing page lists token rates, and its error reference includes an insufficient-balance response; OpenRouter free routes have separate limits.

Can a VPN or IP proxy fix a 429 error?

Usually not. A 429 is a provider request-rate limit, so waiting, reducing requests, changing the API route, or checking account limits is more relevant than changing your IP address.

Keep the key, endpoint, and model ID from one provider route, then refresh Janitor AI and test a short message before tuning generation settings.
