What the error messages in the chat mean: background, causes and the right fixes for rate limits, server issues, context limits, content filters and more.
When a chat request can't be answered, meinGPT shows a specific error message. Most of these errors are temporary and originate with the AI provider (e.g. OpenAI, Anthropic, Google) — not with your account or your usage. This page explains every known error message: what it means, why it happens and what you can do.
Every chat error message includes a "Why am I seeing this error?" link that takes you straight to the matching section on this page.
This has nothing to do with your credits or an extra payment. There are no additional charges and nothing to unlock. It's a temporary capacity limit at the AI provider.
What does it mean? The AI provider has reached a request (rate) limit for the selected model. These limits apply per time window and are set by the provider to share its capacity evenly.
Why does it happen? During peak times or for very popular models, the provider's capacity is briefly exhausted. This affects everyone using that model, not just you.
What can you do?
Use the "Switch to another model" dropdown to pick a different model — this usually works right away.
What does it mean? The AI provider returned a server-side error (e.g. an internal failure or a timeout). The request couldn't be completed as a result.
Why does it happen? These outages are entirely on the provider's side and are usually short-lived.
What can you do?
Try again via Retry.
If the problem persists, use the "Switch to another model" dropdown to move to a different provider/model.
What does it mean? The chat has grown longer than the current model can process at once (its "context window" is exceeded).
Why does it happen? Every model can only consider a limited amount of text at a time. Long chats, large documents or extensive attachments fill up this window.
What can you do?
Use the "Switch to a larger model" dropdown to choose a model with a larger context window.
Or start a New chat and include only the information you actually need.
Keep an eye on the context window indicator in the chat input — it shows how much of the window the current chat already uses, so you can switch or start fresh before you hit the limit.
What does it mean? The AI provider's safety/content filter blocked the request or response.
Why does it happen? Providers screen inputs and outputs for certain categories (e.g. violence, self-harm). Sometimes these filters trigger too strictly, even for harmless requests.
What can you do?
Rephrase your request via Edit message.
Or try a different model via the "Switch to another model" dropdown — filters differ from provider to provider.
Want to know what providers screen for — or think the block was justified? See their usage policies: OpenAI↗, Anthropic↗, Google↗, and Mistral↗.
What does it mean? The connection dropped while the response was being generated, before it fully arrived.
Why does it happen? This can occur with especially long responses or an unstable network connection (e.g. a timeout between browser and server).
What can you do?
If the response finished generating in the background, it isn't automatically streamed in live afterward — that's expected, not a bug. Reopen the chat or refresh the page to see the full, already-saved response.
Try again via Retry.
If it keeps dropping, a shorter prompt or a different model helps.
What does it mean? The AI agent reached the maximum allowed number of tool calls (steps) without completing the task. This is a built-in safety limit on steps — it has nothing to do with your credit balance, so it can happen even when you have plenty of credits left.
Why does it happen? Very complex or vaguely worded tasks can make the agent take too many intermediate steps. A plain chat without an assistant has a hard cap of 20 tool-call steps per response. If the request runs through an assistant, the cap instead depends on the assistant's configured mode: Assistant = 5 steps, Agent = 20 steps, Agent MAX = 50 steps.
What can you do?
Break the task into smaller sub-steps.
Make the request more specific and try again via Retry.
If you're using an assistant, switch to an assistant with a higher mode, or raise the mode yourself in Advanced Options to allow more steps.
Some PDFs are password-protected or carry a rights-management (DRM) profile that restricts access to the content. meinGPT cannot read the content of such PDFs — the model then receives no text, or only partial text. Remove the password protection, or export the document without the DRM restriction, before uploading it.
What does it mean? The attached PDF has more pages than the model can process.
Why does it happen? Models have a page-count limit for PDFs per request, set by the AI provider. This limit is independent of the model's context window — even a model with a very large context window (see AI models) can reject a PDF with many pages once the provider's page limit is reached.
What can you do?
Use a shorter document or split the PDF into several parts.
If needed, use the "Switch to another model" dropdown to choose a model with a higher page limit.
What does it mean? The attached image exceeds the maximum allowed file size (in MB).
Why does it happen? Models only accept images up to a certain file size. Some providers count the combined size of all attached images, so several small images together can also exceed the limit.
What can you do?
Shrink the image or save it in a more compressed format.
If you attached several images, remove some or split them across multiple messages.
What does it mean? Converting the content into the target format (e.g. Word or PDF) failed.
Why does it happen? Certain content or formatting can't be converted reliably — common causes are very long documents, tables with many columns, embedded code blocks, or special characters.
What can you do?
Try again after a short while.
Simplify the document (e.g. remove unusual formatting) and regenerate it.
Choose PDF as the output format instead.
Or use the Copy Content button to paste the text elsewhere (e.g. into Word) instead.
Sometimes the generated document ends up silently corrupted or malformed without an explicit error shown in the chat. Open the generated file promptly to check that it opens correctly — if it doesn't, regenerate the document.
What does it mean? Your workspace has used up all its credits.
Why does it happen? Credit-based models draw from a shared workspace balance. Once it reaches zero, further requests are blocked until more credits are added.
What can you do?
As a workspace admin, top up via Open billing settings.
If you're not an admin, ask a workspace admin to add credits.
Or use the "Switch to another model" dropdown to continue with a model that doesn't require credits.
What does it mean? You've reached your text usage limit for this workspace in the current billing period.
Why does it happen? Workspaces can set a usage tier per member. Once its limit is used up, further requests are temporarily blocked. This counts not only messages you visibly type in the chat, but also actions like document search, website reading, and processing uploaded files toward the same usage category.
What can you do?
Use Request upgrade to ask for a higher usage tier — a workspace admin can assign it.
Seeing a generic error code in the chat like "C-XXXX" (four letters and/or digits, e.g. "C-IRW3" or "C-7F2A")? This is an internal client-side error code that flags an unexpected problem in the browser/client (e.g. while processing the response), not an error from the AI model or provider. Reload the page and try again. If the error keeps happening, note the exact code and contact support.
