How to Set Up DeepSeek on Janitor AI (Step-by-Step 2026 Guide)

If you’ve ever tried to connect DeepSeek to Janitor AI and gotten a scary red “Network Error,” you’re not alone. The good news: the fix is usually just a few small settings, typed exactly right.

This guide walks you through it, step by step, in easy way.

What You’ll Need

Before you start, here’s what to have ready:

• A Janitor AI account
• A DeepSeek or OpenRouter account (both work we’ll explain the difference)
• 5-10 minutes and a device with internet

Quick Glossary: Confusing Words Explained Simply

You’ll see these words a lot. Here’s what they actually mean:

Word	What It Means in Plain English
API	A way for two apps to “talk” to each other. Janitor AI uses an API to send your messages to DeepSeek and get answers back.
API key	A secret password-like code that proves the messages are coming from you. Never share it.
Base URL	The exact web address Janitor AI uses to reach DeepSeek’s servers. One typo here breaks everything.
Model name	The specific AI “version” you want to use, like deepseek-chat.

Here’s the important part: Janitor AI does not have its own AI brain built in. It’s just the app you chat in. DeepSeek is the actual AI “brain” doing the thinking, somewhere else on the internet. The API key and base URL are what connect the two.

Step-by-Step: Setting Up DeepSeek on Janitor AI

Step 1: Get Your API Key

You have two options:

• DeepSeek Direct goes to DeepSeek’s official platform, creates an account, and generates an API key from the developer dashboard. Add a small balance (even $1-2) so the key doesn’t sit at $0, which causes silent failures.
• OpenRouter (easier for beginners) sign up at OpenRouter, generate one key, and you can access DeepSeek plus several other models with the same key.

Step 2: Find the Correct Base URL

This is the step that trips up most people. Type it exactly:

• Deep Seek Direct: https://api.deepseek.com/v1
• Open Router: https://openrouter.ai/api/v1

Missing the /v1 at the end is the single most common mistake; it causes a constant connection error that looks like a bigger problem than it is.

Step 3: Open Janitor AI’s API Settings

1. Log in to Janitor AI.
2. Click Settings.
3. Go to API / Model Settings.
4. Choose Custom API or OpenAI-Compatible API (DeepSeek follows this same format, which is why it works).

Step 4: Enter Your Details

Fill in these three fields carefully:

• API Key paste the key you generated in Step 1.
• API Base URL paste the exact address from Step 2.
• Model Name type one of these exactly:
  • deepseek-chat (good all-around choice for most roleplay and chat)
  • deepseek-reasoner (better for long, complex stories that need deeper thinking)

Step 5: Set Safe Starting Parameters

DeepSeek behaves a little differently than other AI models by default. Start here:

Setting	Recommended Starting Value
Temperature	0.7
Top-p	0.9
Max tokens	2,000-4,000
Frequency penalty	Low or zero

If replies feel repetitive or a bit strange, lower the temperature first before changing anything else.

Step 6: Assign It to Your Character and Test

1. Open a character.
2. Go into its settings.
3. Choose Custom / API model.
4. Select your new DeepSeek setup and save.
5. Send a simple test message like: “Reply in one sentence and tell me what model you are.”

If it replies quickly and clearly, you’re all set!

DeepSeek Direct vs. OpenRouter: Which Should You Pick?

	DeepSeek Direct	OpenRouter
Best for	Long, memory-heavy roleplay	Beginners who might switch models later
Setup difficulty	Slightly more technical	Very beginner-friendly
Pricing	Around $0.20 per 1 million tokens	Similar, plus a free tier available
Free option?	No	Yes search for deepseek/deepseek-r1:free
Extra models available?	No, DeepSeek only	Yes, dozens of models with one key

Common Errors and Fast Fixes

Error	Likely Cause	Fix
No response / endless loading	Wrong base URL or missing /v1	Re-check the exact URL, letter by letter
“Model not found”	Typo in the model name	Confirm spelling deepseek-chat, no extra hyphens
Replies cut off too short	Max tokens set too low	Raise it to 2,000-4,000
Rambling, repetitive text	Temperature too high	Lower it to around 0.7
Bot forgets the story	Missing or weak system prompt	Write a clear persona description in character settings
Error 429	Rate limit reached (often on free tiers)	Wait about 10 minutes, or upgrade your plan

Setting It Up on Mobile

Good news: the process is basically identical on the Janitor AI mobile app, just with a smaller screen.

1. Open the app and tap your character.
2. Tap API Settings (usually in the top corner).
3. Set the provider to Custom / OpenAI Compatible.
4. Enter the same base URL, API key, and model name as the desktop steps above.
5. Save and send a test message.

One extra tip for mobile users: keep your app updated. Older app versions sometimes show connection errors that have already been fixed in a newer release before assuming your settings are wrong, check for an app update first. This alone resolves a surprising number of mobile-only connection problems.

DeepSeek vs. Chutes AI: A Quick Word

You may also see people mention “Chutes AI” as an alternative way to access DeepSeek models. Chutes AI is a hosting layer that runs DeepSeek models with subscription-based access, and it includes a privacy-focused “Trusted Execution Environment” option. For most casual users, DeepSeek Direct or OpenRouter is simpler to set up and troubleshoot. Chutes AI is really only worth considering if you specifically need its privacy features.

It’s worth understanding the data flow before you dive in:

1. You type a message in Janitor AI.
2. Janitor AI sends that message to DeepSeek (or OpenRouter) through the API.
3. DeepSeek’s servers process it and generate a reply.
4. The reply travels back through the API to your Janitor AI screen.

This means your conversations are handled under DeepSeek’s privacy policy during that step, not only Janitor AI’s. If privacy matters to you, it’s worth reading the provider’s data retention terms before long roleplay sessions, especially if you’re sharing personal details in character backstories.

Managing Costs So You Don’t Get Surprised

Janitor AI does not automatically stop you from spending once your key is connected, it simply keeps sending requests as long as your account has balance. To stay in control:

• Check your usage dashboard on the DeepSeek or OpenRouter site regularly
• Set a spending alert if your provider offers one (many notify you at 80% of a budget)
• For very long chat sessions, consider starting a fresh conversation occasionally, since longer context means more tokens used per message

Writing a System Prompt That Actually Sticks

Most “my bot forgot who it is” complaints trace back to one thing: a weak or missing system prompt. This is the background instruction that tells the AI how to behave for the whole conversation, not just one message. A strong system prompt usually includes:

• A short description of the character’s personality (calm, sarcastic, cheerful, etc.)
• Key backstory details the bot should remember
• How it should handle situations that aren’t covered in the opening scene
• Any speech patterns or phrases specific to that character

A vague system prompt like “friendly character” gives the AI almost nothing to work with. A detailed one, even just three or four sentences, makes a noticeable difference in how consistent the roleplay feels over a long conversation.
