A WordPress draft expected to be about 3,000 characters was saved at 4,169,336 characters, according to ACS Developer. The author compared that size with API-console token figures and found thousands of sections sharing a small set of MD5 fingerprints. The pattern supports a case-specific diagnosis of duplication—but it does not independently prove which component repeated the content or establish a wider API defect.
What happened in the oversized WordPress draft?
ACS Developer reports that an AI article-generation plugin saved a WordPress draft of 4,169,336 characters, although the intended article was around 3,000 characters. The author says the API console showed seven requests, 13.86k input tokens and 19.55k output tokens. Those are the author’s reported measurements, not independently verified API telemetry. [c001]

The scale mismatch prompted the author to investigate whether the draft had been appended repeatedly after generation. The author reports that the WordPress post’s date and modified fields matched to the second, suggesting the oversized content was written in one save, and that a code review found no self-concatenation routine. These checks narrowed possible explanations; they do not identify the remote or local component responsible. [c002] [c003]

The author split the saved HTML at H2 headings, kept non-empty sections, encoded each section as UTF-8, calculated its MD5 digest and counted how often each digest appeared. The report gives these results:
#1 Best Overall
| Reported measure | Case-report result |
|---|---|
| Saved draft size | 4,169,336 characters, as reported by ACS Developer in 2026 |
| API output usage | 19.55k output tokens, as reported by ACS Developer in 2026 |
| Sections fingerprinted | 2,065 |
| Distinct MD5 digests | 28 |
| Most frequent digest | 432 occurrences |
| Next two most frequent digests | 431 and 357 occurrences |
The section counts and digest frequencies are also author-reported figures, not independent measurements. The author says the sections appeared in a repeated pattern and interprets the result as roughly 28 generated sections copied across the larger document. [c002]
This technique is useful because it can turn an enormous document into a compact list of candidate duplicates. It works best when the chosen boundaries are stable: here, the author used H2 headings. If repeated material starts or ends in the middle of a section, this method may not reveal the full pattern.
What does an MD5 match prove—and what does it not?
A matching digest is a practical signal that two sections may be identical, not an infallible identity test. Python’s official documentation warns that MD5 has known hash-collision weaknesses. For a stronger byte-equality claim, group sections by digest and compare the underlying UTF-8 bytes directly; alternatively, use a modern digest to find candidates and still verify the bytes. [c004]
In this incident, the reported combination of a large mismatch between saved content and token usage, one reported save, and a small set of recurring section fingerprints is consistent with duplication after generation. The author attributes it to a response-assembly layer and says the client side was not responsible. But the public account does not include the raw API response, provider-side traces or an independent replication, so readers cannot independently establish that attribution from the report alone. [c001] [c002] [c003]
The author explicitly limits the conclusion to one observation from their environment; it does not establish a systemic or provider-wide defect. Nor does a nonzero temperature prove that byte-identical repetition could not occur. Sampling settings alone cannot locate where duplication happened. [c003]
How to investigate a response that is much larger than expected
- Compare artifact size with API metadata. Check the saved character or byte count against request count and token usage. A large mismatch is a reason to investigate, not by itself proof of duplication. [c001]
- Check save and update history. Inspect timestamps and available revision or application logs for evidence about whether content was written once or accumulated through repeated updates. A matching timestamp narrows possibilities but does not identify the cause. [c002]
- Split content at meaningful boundaries. Use a stable structure such as headings, then retain non-empty sections so repeated blocks can be compared efficiently. [c002]
- Group by digest, then verify candidate matches. Count fingerprints to surface likely duplicates; compare the underlying bytes before asserting exact equality. A digest count alone does not prove root cause. [c004]
- Add validation before parsing and persistence. Check raw response size, decoded content length and structural anomalies before expensive processing or saving. [c005]
What safeguards can prevent an oversized draft from being saved?
ACS Developer describes three pre-save checks: reject raw responses above a configured byte limit before JSON parsing, reject decoded content above an application-specific character limit before saving, and flag headings repeated at least three times. The author gives 1,500,000 raw bytes and 100,000 content characters as sample thresholds; they are examples for that application, not universal limits. Choose thresholds for the expected workload and make rejections visible for inspection rather than silently truncating content. [c005]
Unconditional retries are also risky: a retry might return the same bad response. An explicit error preserves the anomalous payload for investigation and avoids presenting a shortened or repeated draft as if it were valid. [c005]
