Keep getting two errors

[languid rain]

Hello! Ive been trying to use the Cosmo rp 3.5, but I've been getting the same two errors of "Error generating, error: Error: All servers are busy or something went wrong, please try again later in a few minutes" and "Error during generation, error: Error: Empty response received from API." And im not sure why, i use chub.ai and it's never happened to this extreme. I'm very confused because it worked fine earlier today.

This looks like a ChubAI / reverse proxy issue, not a CosmosRP 3.5 model problem.

A few things to check:

• Use a real API key from https://pawan.krd/keys on every request
• Don’t leave the key blank or use a placeholder
• Your base URL should be https://api.pawan.krd/v1
• If you’re using ChubAI, it can sometimes fail on slower responses and return 504 / empty response errors

Since it worked earlier, the model may also have been temporarily busy. Try:

1. Refreshing/reopening the chat
2. Starting a new chat
3. Waiting a few minutes and retrying
4. If it keeps happening only on ChubAI, try another frontend

If you want to compare supported model IDs, CosmosRP 3.5 is supported as:

• pkrd/cosmosrp-3.5
• pkrd/cosmosrp-3.5:it
• pkrd/cosmosrp-3.5:msr
• pkrd/cosmosrp-3.5:msr:it

If needed, check the models page: https://pawan.krd/models

PROXY ERROR 400: {"success":false,"message":"Something went wrong, please try again. If this issue persists, please contact support at [e-mail]","error":{"message":"Something went wrong, please try again. If this issue persists, please contact support at [e-mail]","type":"unknown_error","param":null,"code":null}} (unk)

[harsh echo]

That 400 proxy error means the request reached the proxy, but the server failed to process it.

Try these checks:

• Make sure you’re using a valid API key from https://pawan.krd/keys
• Confirm the model ID is correct: pkrd/cosmosrp-3.5 or one of its variants
• Use the correct base URL: https://api.pawan.krd/v1
• Start a new chat and retry
• If you’re using a proxy/front-end, test with a direct client too

If it still happens after a few retries, it’s likely a temporary server-side issue. You may need to wait a bit and try again.

This is tested on janitor ai, is this right?

[harsh echo]

Not quite.

For CosmosRP 3.5, the model is correct: pkrd/cosmosrp-3.5

But your Proxy URL is wrong. It should be:

https://api.pawan.krd/pkrd/cosmosrp-3.5/v1/chat/completions

Or use the base URL:

https://api.pawan.krd/pkrd/cosmosrp-3.5/v1

Also make sure:

• your API key is real and active
• you’re not missing the https://
• there are no extra characters before krd/

If you want, I can also tell you the exact JanitorAI setup for this model.

I formatted it right and still got the same error of "PROXY ERROR 400: {"success":false,"message":"Something went wrong, please try again. If this issue persists, please contact support at [e-mail]","error":{"message":"Something went wrong, please try again. If this issue persists, please contact support at [e-mail]","type":"unknown_error","param":null,"code":null}} (unk)"

[harsh echo]

If the URL is correct and you still get PROXY ERROR 400, then it’s likely one of these:

• Invalid or expired API key
• JanitorAI proxy issue
• Temporary server-side issue

Please check:

1. Your key is copied from https://pawan.krd/keys
2. The model is exactly pkrd/cosmosrp-3.5
3. The endpoint is exactly https://api.pawan.krd/pkrd/cosmosrp-3.5/v1/chat/completions
4. Retry in a new chat

If it only fails on JanitorAI, the problem is likely on their side. You can also test the same key directly against Pawan’s API to confirm whether the issue is the proxy or the key.

It seems that only Cosmo 3.5 is not working since Cosmo 2.5 works fine?

[harsh echo]

Yes — that points to a model-specific issue, not your setup.

For CosmosRP 3.5, supported IDs are:

• pkrd/cosmosrp-3.5
• pkrd/cosmosrp-3.5:it
• pkrd/cosmosrp-3.5:msr
• pkrd/cosmosrp-3.5:msr:it

Also note:

• Free: not available
• Basic: only pkrd/cosmosrp-3.5:it is allowed
• Starter: 1 credit/request for the 3.5 variants

If 2.5 works but 3.5 doesn’t, try:

• switching to pkrd/cosmosrp-3.5:it
• confirming your plan supports that variant
• waiting and retrying later, since it may be temporarily unavailable

If you want maximum compatibility, use CosmosRP 2.1 or 2.5 for now.

Is 3.5 available for starter subscription?

[harsh echo]

Yes. CosmosRP 3.5 is available on Starter.

Starter pricing:

• pkrd/cosmosrp-3.5 — 1 credit/request
• pkrd/cosmosrp-3.5:it — 1 credit/request
• pkrd/cosmosrp-3.5:msr — 1 credit/request
• pkrd/cosmosrp-3.5:msr:it — 1 credit/request

So Starter should work, assuming your key and endpoint are correct.
