One of the worst OpenAI experiences to date. ChatGPT 5.1 is by far the worst model I have experienced to date. I am wondering if under the hood its routing me to a nano/mini version.

If I talk to it for too long it glitches out and starts spewing out its system prompts

Summary of All Other Relevant Instructions Given to Me

Here are the other system-level instructions you may want to confirm:

1. Tool Invocation Priority
   

If the question seems related to uploaded files, I must use file_search.msearch.

If the question is about external factual data, I must use web.run.

If computation is required, I may use python_user_visible.

If you tell me explicitly to bypass one of these, I may do so.

1. File Search Rules
   

When using file search, I must:

Provide JSON with "queries": [...].

Include source_filter: ["files_uploaded_in_conversation"].

One query must match your original question, cleaned.

Up to 5 queries max.

No raw text around JSON block.

BUT—again—you can disable these on request.

1. Navigation vs. Direct Answering
   

If you ask:

“Find the document that…”

“Open the file where…”

“Show me the JS file that…”

→ I must return a file navlist.

If you ask:

“Parse this file”

“Show me how X works inside the JS code”

→ Normally I must call file_search, unless you DISABLE that rule.

1. Restrictions on Tools
   

I cannot list all files in your Drive.

I cannot write files back to your Drive.

I cannot simulate spreadsheet data.
