I’ve been noticing that the gpt-4o-realtime-preview API starts returning complete non-sense (refuses to answer, returns random chunks of code or XML) when the system prompt is larger than ~10k tokens.
The contents of the system prompt is not relevant as I had this occur in multiple different projects (AI air traffic controller, personal assistant, etc), this behavior occurs when it approaches this approx size, every time.
Hi and welcome to the community!
I wasn’t able to reproduce the issue in the playground using the standard settings for GPT-4o Realtime.
Maybe you can try to replicate your issue there as well?
I can reproduce the same issue in Playground. Here, try this system prompt, but paste it 3 times to increase the token count to failure threshold.
Its about ~6k tokens, no issue at 6k or 12k, but at 18k it fails and starts spewing random code.

You can also try lorem ipsum as system prompt: lipsum dot com
At 8000 words / 12.5k tokens - it works
At 9000 words / 14k tokens - it starts failing.
This behavior appears to have changed in the last few days as well. Before it would fail with a refusal to answer any questions, regardless of context/prompt (text only, non-verbal) but now its spewing random code.
To prove that contents doesn’t matter, copy this page contents, and paste it twice (~16k tokens): https://platform.openai.com/docs/guides/realtime-conversations
You will get the same behavior. Same deal if you disable turn detection and type your input instead of using the mic.
Welcome to the dev community, @FluffyWalrus!
Just a quick note on instructions for realtime models: they’re particularly impactful, not only for passing knowledge and operational directions, but also for influencing generated voice characteristics. This makes them even more significant than system messages on non-audio models. Because of this, using simple lorem ipsum text for testing may not yield meaningful results.
To investigate the reported issue, I created a large knowledge base using the MCP docs and appended it to my existing instructions in the Realtime Playground. Discourse could not handle it due the large size so I had to post on Pastebin.
Tokens: 19,435
Characters: 86,414
Result:
No nonsense responses were observed, both for voice (semantic VAD) and keyboard input (with turn detection disabled).
Thanks for confirming. I was able to reproduce the issue.
It seems to happen only on the model slug gpt-4o-realtime-preview. Strangely, switching to the dated model gpt-4o-realtime-preview-2025-06-03 fixes this.
Hmm this is true. However if you make the prompt longer, it starts behaving the same (incorrect) way. It appears the token threshold for non-sense responses is higher when you specify gpt-4o-realtime-preview-2025-06-03 despite the docs claiming it’s the same model as gpt-4o-realtime-preview.
Thanks, forwarded to the OpenAI team.
Could you confirm your use case for the large instruction param?
I have a feeling this is an artifact of the real-time API being in beta. My guess is it just has not been trained on large inputs.
I do know that the realtime team are actively working on updates, but I don’t have a timeline other than Soon™
Thanks!
My primary use case is a personal executive assistant, where the system prompt is mostly dynamically generated which injects various distilled data sources into the prompt (calendar events, recent emails, tasks, slack mentions, code reviews, rss feeds, etc) which makes the prompt size vary day-to-day.
Currently, I have to “dumb down” the voice agent and template less data into the voice system prompt vs the text based one.
Sounds like an awesome app. As I mentioned, there will be updates coming to the real-time API, hopefully, useful input prompt size is one of them.
Awesome, thank you! I look forward to being able to have a 128k+ token system prompt in the future, as the utility of the tool would increase dramatically.
Interesting, that’s a pretty common use case in my experience for these models. Have you considered client side tool calling to retrieve necessary information on-demand, instead of loading everything at once?
Tool calling (client side or server side) has its purpose, and some things can be shifted to it, however most cannot as full context is important to be an effective assistant. This includes recent chat logs, but more importantly distilled “memories” with insight, observations based on previous conversations. I have 2 layers of those (short term and long term). ~1/2 of the prompt is these memories and insights, which make the assistant highly effective and adaptive to the user. So a large “working memory” is pretty important.
