Hidden Costs Breakdown

Opaque Credit and Usage Consumption

high overage

API credits are consumed without per-request breakdowns, making it impossible for users to audit or predict costs. When disputes arise, OpenAI support acknowledges that credits were consumed but cannot provide itemized usage details, leaving users with no recourse. This applies across all OpenAI API products including Whisper transcription.

trustpilot
Paid subscription, poorly explained monthly cap, unpredictable consumption, €100 surcharge offered once the project is started, and no proper visibility before being blocked.so it's a scam

trustpilot
I have no idea that it would get so many things wrong. I've wasted 8000 units just in the last two hours and it got every single thing I asked wrong.

Undisclosed Usage Caps That Block Access Without Warning

medium overage

Paid plan subscribers report hitting undisclosed rate limits and usage caps mid-workflow with no advance warning. Access is suspended without compensation or clear explanation, disrupting time-sensitive workloads. For Whisper API users, this means transcription jobs can fail mid-batch when quotas are hit.

trustpilot
After generating around 15 images, my access to image generation was suddenly blocked for more than 18 hours. This caused delays and disrupted my workflow.

trustpilot
After using the service, I found the usage limits to be far more restrictive than expected, making the service significantly less useful than advertised.

Multi-Speaker Diarization Errors Waste Credits

medium overage

When transcribing audio with two or more overlapping speakers, the model can produce looped or duplicated output rather than distinguishing voices. Users report consuming large volumes of units re-rendering the same audio without resolution, effectively paying for failed transcription attempts.

trustpilot
I have no idea that it would get so many things wrong. I've wasted 8000 units just in the last two hours and it got every single thing I asked wrong. I have two people talking, for example, and they're talking at the same time saying the same words and it won't stop doing that no matter how many times I render a new verge, horrible

Billing Disputes Met With Automated Responses and No Human Escalation

high support

Users who experience unexpected charges, subscription errors, or credit disputes consistently report receiving AI-generated form responses rather than human review. Cases are opened, assigned new case numbers, and then closed without resolution. This makes recovering erroneous charges effectively impossible through normal support channels.

trustpilot
I immediately explained the mistake and repeatedly supplied receipts, account information and existing case references. Instead of resolving it, I received generic AI-assisted replies, contradictory statements about my payments and several new case numbers that appeared to ignore the existing complaint.

trustpilot
OpenAI Support reviewed Cases 11354938 and 11860533 but repeatedly refused the refund. They did not provide any specific contractual clause or legal basis for the refusal.

No Itemized API Credit Consumption Records

high support

OpenAI explicitly refuses to provide itemized credit consumption logs for API usage, making it impossible to audit which requests consumed credits. API users who purchase prepaid credits and experience unexpected depletion have no recourse — support has confirmed in writing that this information is not available, leaving teams unable to verify legitimate vs. erroneous consumption on Whisper API workloads.

trustpilot
When I asked for an itemized record of the consumption, OpenAI refused five separate times in writing: "we're unable to provide itemized credit consumption logs, internal ledger records, or other internal usage data."

API Credits Disappearing Without Explanation or Refund

critical overage

Multiple users report prepaid API credits being wiped to zero without any corresponding usage activity, with no refund or resolution from support. For Whisper API workloads that depend on prepaid credit pools, unexpected credit loss can halt production transcription pipelines mid-operation.

trustpilot
In July 2026 I paid $242 for prepaid ChatGPT Credits (Codex). My balance of 491.8 credits was wiped to zero within one second with zero usage in between (recorded in my application logs); after I paid for 1,000 more, OpenAI support confirmed in writing my balance was "still $0". Later purchases burned out in minutes with no spend-rate warning while the service kept asking me to pay again - four times in one evening.

trustpilot
I'm a business customer and I received a grant of 1000$, that grant was deleted after about 7-8 weeks. No comment, no email. Just deleted.

Credit Allowances Reduced Mid-Subscription Without Notice

high overage

Users on subscription plans report that internal credit allowances have been substantially reduced mid-subscription without any notification. For API-dependent teams, this results in paying the same price for dramatically reduced usage capacity — one user reported an 80% reduction in usable credits per seat.

trustpilot
It's 440$ anually per 2 seats and the internal Credits available per seat were reduced at least by 80% since the subscription started. When one of those accounts was usable for about 1-2 hours per 5 hour rate limit, it's now 2 hours per week.

Automated Support With No Effective Human Escalation

high support

OpenAI's customer support for billing disputes is handled primarily by LLM-generated responses that ignore prior correspondence and provide no meaningful escalation path. For API users facing credit loss or billing errors, disputes go unresolved for weeks with no access to a human decision-maker — one user confirmed OpenAI's own internal support tooling uses LLMs rather than human agents.

trustpilot
The worst customer support experience i have ever encountered in 25 years of working with IT service providers. I don't believe there is an actual human being behind the replies i got. Every reply i sent was met with a complete disregard for my previous reply and at times it could take a week to receive one of these utterly useless replies.

trustpilot
Due to a bug in their system I was able to see internal data of their customer support, which turned out to be LLMs that basically confirm that their own terms say grants are valid for 12 months and there is no indictation why I should have had 800$ in Credits deleted.

Unexpected Charges and Strict Refund Denials

medium overage

Multiple users report unauthorized charges on cancelled accounts, duplicate subscription billing, and refusal of refunds even for clear billing errors. OpenAI applies strict time windows for refund eligibility that exclude legitimate claims, and partial refunds are common even when users had no access to the charged service.

trustpilot
Had no active subscription and was charged 30$. Said account was reactivated which it never was

I had a free trial with this company and cancelled it well before the trial ended, I have proof of this, and they st...
