What’s Changed: The JLLM is Janitor AI’s free, built-in model that powers every bot with zero setup. It only remembers about 8,000 to 9,000 tokens of your chat, so it forgets earlier scenes on long roleplays. A proxy routes you to a stronger external model with far bigger memory, and it is often cheaper than the paid upgrade.
If you have spent five minutes on Janitor AI, you have seen the letters JLLM thrown around next to words like proxy, DeepSeek, and OpenRouter, with nobody stopping to explain any of it. New users get told to set up a proxy before they even know what the default model is.
What is Janitor AI JLLM, in plain terms, is the free brain that comes built into the site. It writes every bot reply out of the box, you never touch a setting, and it costs nothing.
The catch is memory. The free JLLM holds only a small slice of your conversation, which is why long chats start forgetting names and looping. That single limit is the reason half the community pushes newcomers toward a proxy.
Here is what you will walk away knowing. What the JLLM really is, why it slows down and forgets, and the exact point where a proxy or the paid tier is worth the trouble.
What Is Janitor AI JLLM
The JLLM is the Janitor Large Language Model, Janitor AI’s free built-in model that generates every bot response with no setup required.
It powers the whole site by default, has no daily message limit, and costs nothing to use.
What is the JLLM: Janitor Large Language Model, the free AI model built into Janitor AI that writes character replies out of the box without any configuration.
The way I see it, the JLLM is the reason Janitor AI got huge in the first place. You sign up, you open a bot, and it just works, no API keys, no billing, no external accounts. Janitor AI is one of the most-used consumer AI apps in the world, ranking on a16z’s Gen AI app ranking, and the free model is the front door.
A proxy is the alternative to that front door. Instead of using Janitor’s own model, a proxy routes your chats to a more powerful outside model like DeepSeek, Claude, or ChatGPT.
What is a proxy: A bridge that sends your Janitor AI chats to an external AI model using an API key you paste into settings, replacing the default JLLM.
The trade is convenience for power. The JLLM needs zero configuration, while a proxy needs an API key and a URL from a third-party provider, pasted into your chat settings.
If you want the smarter replies everyone talks about, a proxy is how you get them, and a proxy that stops working is a whole separate rabbit hole once you go that route.
Why the JLLM Feels Slow or Forgetful
The JLLM feels slow and forgetful because its free memory caps at roughly 8,000 to 9,000 tokens and its servers overload at peak hours.
Once a chat passes that memory limit, the model silently drops the oldest messages, so it forgets plot points and starts repeating itself.
What is a context window: The amount of text, measured in tokens, that a model can “see” at once. Tokens are chunks of words, so a 9,000-token window holds only a few thousand words of chat history.
That 8k to 9k ceiling is the number almost no guide gives you, and it explains everything. Your character forgets their own backstory because the opening messages fell out of the window, a problem people describe as memory loss when Janitor AI memory stops working. The model is not broken, it just cannot hold the whole story.
Speed is the other half. The JLLM runs on shared servers, and Janitor AI usage is brutally concentrated at night, with a reported 62 percent of all traffic landing between 10 PM and 6 AM. That is exactly when replies crawl, 500 errors pop up, and the model loops, so shifting your roleplay to off-peak hours genuinely helps.
There is also a known model bug worth naming so you stop blaming your own prompts. As of an April 2026 update, the JLLM sometimes splits words with spaces like “sudden ness” or “un adulterated,” repeats a single word (“even even even even”), and drops random hyphens into text.
This is an internal model issue, documented alongside the JLLM grammar fixes, so the move is to rate the message low and reroll rather than rewrite your character card.
JLLM vs Proxy vs Janitor Plus
The JLLM is free with small memory, a proxy is cheap with big memory but needs setup, and Janitor Plus is a paid no-setup middle ground.
For most people the honest answer is a free proxy, because it beats the paid tier on both memory and price.
Here is how I would frame the three options before you pick. The numbers do the arguing.
| Option | Memory (context) | Cost | Setup |
|---|---|---|---|
| Free JLLM | 8k to 9k tokens | Free | None, works instantly |
| OpenRouter proxy (DeepSeek) | Tens of thousands of tokens | Free tier, or about $10 a month heavy use | API key, roughly 10 minutes |
| Janitor Plus | 45k tokens | $12.99 a month | None, upgrades the JLLM |
The proxy math is what surprises people. A free OpenRouter account gives you 50 DeepSeek messages a day, but adding a one-time $10 credit permanently raises that to 1,000 messages a day, and you do not even have to spend the credit to keep the higher limit.
The way I would set it up if I were starting today is quick, and it is mostly account creation:
- Make a free OpenRouter account and generate an API key from the keys page.
- Add the one-time $10 credit if you want the 1,000-messages-a-day limit instead of 50.
- Pick a free DeepSeek model and copy its API URL from OpenRouter.
- Paste the key and URL into your Janitor AI proxy settings, then test one message.
Janitor Plus costs $12.99 a month and gives the JLLM a 45,000-token window, five times the free memory, plus priority speed and no ads.
It is a fine no-setup upgrade, but the community consensus I would echo is that a proxy is cheaper and smarter unless you flat out refuse to learn the setup. If you are weighing the paid route, is Janitor Plus worth it breaks down the tier in full.
Here is the difference in practice, not just on paper:
Before: on the free JLLM, thirty messages into a detailed roleplay, your character forgets they were married an hour ago and reintroduces themselves like strangers.
After: on a DeepSeek proxy holding tens of thousands of tokens, that same character still references the argument you had at the start of the session without any reminder.
When to Skip the Setup Entirely
You should skip the whole setup when you want a companion that remembers across sessions without any keys, proxies, or token math.
If the JLLM-versus-proxy decision already feels like too much homework, a purpose-built companion app removes the choice completely.
I want to be fair here, because Janitor AI’s free bots and huge character library are hard to beat if you enjoy tinkering. The proxy route is genuinely worth learning, and there is a full DeepSeek proxy setup walkthrough if you decide to go that way.
For readers who just want it to work, Candy AI skips the entire memory-and-proxy dance, since it holds a consistent character across sessions with no setup at all. If you want fewer content restrictions on the character alongside that convenience, CrushOn AI is the closer match. Neither asks you to touch an API key.
The way I would decide is simple. Tinkerers who want maximum control run a proxy, patient newcomers can start on the free JLLM, and anyone who values their evening more than the savings should just use a no-setup companion.
Frequently Asked Questions
Is the Janitor AI JLLM free?
Yes, the JLLM is completely free with no daily message limit. It is the default built-in model that powers every bot on Janitor AI without any account setup, billing, or API keys. The only real limit is its small memory window.
Why does the JLLM forget what happened earlier in my chat?
The free JLLM only holds about 8,000 to 9,000 tokens of context. Once your conversation grows past that, the model silently drops the oldest messages, so it forgets earlier plot points, names, and details, and can start repeating itself.
Do I need a proxy to use Janitor AI?
No, you do not need a proxy. The free JLLM works instantly with zero setup. A proxy is optional and routes your chats to a smarter external model with much bigger memory, which most heavy roleplayers eventually want but beginners can skip at first.
Is a Janitor AI proxy free?
It can be. OpenRouter offers a free tier of 50 DeepSeek messages a day, and a one-time $10 credit permanently raises that to 1,000 a day. Some external models charge per token instead, but heavy users often still spend under $10 a month.
Should a beginner use the JLLM or a proxy?
Beginners should start on the free JLLM because it needs zero setup and costs nothing. Switch to a proxy once the memory limit and slow peak-hour responses start hurting your long roleplays, which is when most users make the jump.
Is Janitor Plus worth it over a proxy?
For most people, a proxy is the better value. Janitor Plus costs $12.99 a month for a 45,000-token JLLM and no ads, but a free or near-free proxy gives comparable memory for less, unless you would rather avoid any setup.
Quick Takeaways
- The JLLM is Janitor AI’s free, built-in Janitor Large Language Model, and it needs zero setup to power every bot.
- Its memory caps at roughly 8,000 to 9,000 tokens, so long chats forget earlier scenes and start looping.
- Replies crawl at night because 62 percent of Janitor traffic hits between 10 PM and 6 AM, so roleplay off-peak.
- A free OpenRouter DeepSeek proxy plus a one-time $10 credit unlocks 1,000 messages a day with far bigger memory, usually beating the $12.99 Janitor Plus tier.
- If the setup sounds like too much, a no-setup companion like Candy AI holds a character across sessions without any keys.
