An AI hallucination in an SF330 rarely looks like nonsense. It looks like a plausible, confident overstatement of a real person or project: a promoted role, a rounded year count, a certification nobody holds. Before you submit, run a verification pass. Left unchecked, those errors cost evaluator credibility and, after April 24, certification exposure.
The Failure Mode Isn't Fabrication, It's Promotion
When people worry about AI in proposals, they picture invented projects and made-up firms. That happens, but it's the easy case to catch. The dangerous case is subtler. AI tends to take something real and make it slightly better than the record supports.
A staff engineer who did construction observation becomes a "design lead." Eleven years of experience rounds to fifteen. A relevant certification gets added because the role usually has one, even though this person let theirs lapse. A project the firm supported as a sub gets described as a project the firm led. Each change is small and reads beautifully, which is exactly why it slips through. Cumulatively, the package describes people and work the firm can't fully back up. This is the most common AI mistake on proposals among the 53% of firms now using it, and it's the one a fast read won't catch.
The Four Places Hallucinations Hide
On a federal SF330, overstatement tends to collect in four sections. Knowing where to look is half the verification job.
Section E (resumes of key personnel). The richest target. Roles get upgraded, years get rounded, education gets embellished, and certifications appear that the person doesn't currently hold. Every one of these is checkable against a source record, and every one is a credibility risk if an evaluator probes it during interviews.
Section F (example projects). Scope, role, and outcome are the usual overstatements. A $4M task gets described as a $40M program. A supporting role reads like a lead role. An outcome gets stated more cleanly than the project actually delivered. The project is real; the description outruns it.
Section G (key personnel participation). The matrix that maps people to projects. AI will sometimes assert that a named person worked on a listed project when they didn't, because the pairing is plausible. This is the section most likely to contradict Sections E and F if nobody cross-checks them.
Section H (additional information and commitments). Methodology, staffing, and technology commitments. The risk here isn't a factual error so much as a promise the firm can't resource. An AI-drafted Section H will happily commit to a staffing level or an approach that sounds strong and isn't backed by the team actually assigned.
The Pre-Submission Verification Pass
This is a focused read, not a full rewrite. On a typical SF330 it adds about 30 minutes, and it's the cheapest insurance a submittal buys. Run these five checks before the package goes out.
-
Trace every named person to a source record. For each resume in Section E, confirm the role, years of experience, degrees, and certifications against the firm's actual record for that person. If the source says "construction observation," the SF330 cannot say "design lead."
-
Confirm project facts against the project sheet. For each Section F example, check the dollar value, the firm's actual role, the dates, and the stated outcome against the source project record, not against what reads well.
-
Cross-check Section G against E and F. Make sure every person-to-project pairing in the participation matrix is one the resumes and project examples actually support. Contradictions between sections are a fast way to lose evaluator trust.
-
Confirm Section H commitments are real and resourced. Every promise about staffing, methodology, or technology should match what the assigned team can actually deliver. If it's aspirational, cut it or commit to it for real.
-
Flag anything the source can't substantiate. If a claim can't be traced to a record, it doesn't go in the submittal. "Probably true" isn't a standard you want to defend to an evaluator or a contracting officer.
The pattern across all five: every claim in the document should tie back to something the firm can show. The same discipline prevents the SF330 mistakes that quietly cost firms shortlist points.
Why Generic Chat Tools Hallucinate More Than Records-Grounded AI
Most of these errors trace back to one thing: the tool has no idea what's true about your firm. A general-purpose chat assistant doesn't have a view of your staff records or your project history. When you ask it to write a Section E resume, it fills the gaps with what's statistically likely for that role. That's where the promoted titles and invented certifications come from. It isn't lying. It has nothing to check against, so it guesses, confidently.
AI built around the firm's own records works from the opposite direction. If the underlying staff record says a person is a junior staff engineer with eleven years and a lapsed certification, the tool can describe that and only that. It can't promote the person to design lead, because the source doesn't say so. The verification job shifts from "did the AI invent something" to the much smaller "is this record accurate," which is a question the firm controls.
This is the case for grounding proposal AI in structured staff and project data instead of a blank chat box. RFPM.ai generates resumes and project sheets from the firm's own records, so the content describes what's recorded rather than what's plausible. It doesn't remove the verification step, but it shrinks it from catching invention to confirming accuracy.
None of this is an argument against using AI on an SF330. After April 24, FAR 52.222-90 turned an AI-introduced misstatement from a credibility problem into a certification problem, which raises the stakes on the verification pass, not on the drafting. The firms getting this right aren't avoiding AI. They're checking its work against a source of truth before they sign.

Frequently Asked Questions
What's an AI hallucination on a proposal?
An AI hallucination is content the model states confidently but the facts don't support. On a proposal it rarely looks like obvious nonsense. It looks like a plausible overstatement: a promoted title, a rounded year count, an added certification, an inflated project scope. It reads well, which is exactly why a quick review misses it.
Can AI fabricate staff credentials?
Yes. A general-purpose AI tool with no access to your staff records fills gaps with what's statistically likely for a role, which can mean adding a certification the person doesn't hold or upgrading their title. Check every AI-drafted Section E resume against the firm's actual record for that person before it goes in the submittal.
How do I check an AI-drafted SF330?
Run a verification pass. Trace each named person's role, years, and certifications to a source record; confirm Section F project facts against the project sheet; cross-check Section G against Sections E and F; and confirm Section H commitments are real and resourced. Flag anything that can't be traced. The pass adds roughly 30 minutes.
Is AI-drafted content a compliance risk?
It can be. After April 24, FAR 52.222-90 means an unverified AI overstatement in a federal submittal isn't just a credibility issue but a certification exposure: the firm signs representations it may not be able to substantiate. The tool isn't the problem. Submitting without verifying its output is.
Does records-based AI still hallucinate?
It can still phrase or summarize imperfectly, so the verification pass is still worth running. But AI grounded in the firm's own records can only describe what's recorded, so it can't invent a certification or promote a junior engineer to design lead the way a general-purpose tool can. The job shrinks from catching invention to confirming accuracy.
