Differences between edit API and edit playground causes client errors

I’ve been looking at incorporating the edit API into an application, but I’m finding that things that work fine in the edit playground do not work in the edit API, and I’m a bit perplexed as to why this might be, since it appears that the site is hitting the same endpoint.

For example, I submitted the following request to both:

Replace all abbreviations, honorifics, titles, political party indicators, and all
other shortenings with their full pronunciation.

temperature: 0.1

top_p: 1

In the playground it works as expected, but when making the request against the API I get a 400 error with the error response

"error": {
    "message": "Could not edit text. Please sample again or try with a different temperature setting, input, or instruction.",
    "type": "invalid_edit",
    "param": null,
    "code": null

I’ve gotten this error for many API requests, but never in the playground. There appears to be a correlation with the length of the text in the request, as reducing the text reduces the incidence of these errors (but doesn’t eliminate them totally). Is there some hidden text limit or processing time limit that I’m hitting? Is it possible to make this configurable?

Furthermore, chopping up the text in my requests makes my application very slow, since each API request takes quite a while to serve, so I’d very much like to send as much text as possible in each request.
