Estimated costs for evaluating articles (e.g. video transcripts or descriptions) using OpenAI API.
Based on the cheapest (GPT-4.1 nano) and next-cheapest (GPT-5 mini) models as of March 2026.
Assumptions:
| Model | Article Length | Input Tokens (approx.) | Output Tokens | Cost per Evaluation | Evaluations per $10 |
|---|---|---|---|---|---|
| GPT-4.1 nano | 500 words | 967 | 500 | $0.00059 | ≈ 16,949 |
| GPT-4.1 nano | 800 words | 1,367 | 500 | $0.00067 | ≈ 14,925 |
| GPT-4.1 nano | 1,200 words | 1,900 | 500 | $0.00078 | ≈ 12,821 |
| GPT-5 mini | 500 words | 967 | 500 | $0.00124 | ≈ 8,065 |
| GPT-5 mini | 800 words | 1,367 | 500 | $0.00134 | ≈ 7,462 |
| GPT-5 mini | 1,200 words | 1,900 | 500 | $0.00148 | ≈ 6,757 |
Note: These are rough estimates only.
Real costs depend on exact prompt length, output verbosity, caching (if any), and model behavior.
Always check your actual usage in the OpenAI dashboard.
No, not in the free version. A pro version will include the ability to add your own custom text for evaluation. No ETA yet — availability depends on user demand and development priorities.
Yes. It is a native WordPress plugin, tested with PHP 8+ and the latest WordPress version (as of 2026).
Yes, an OpenAI API key is required for the plugin’s AI-powered evaluation features (GPT-based analysis of EEAT signals from video transcripts, descriptions, etc.).
How to obtain an OpenAI API key (step-by-step):
Important: API usage is charged per token. Monitor usage and set limits in your OpenAI dashboard. Never share your key publicly.
Optional. The plugin functions without it for manual input and basic features. Adding a YouTube API key allows automatic retrieval of video metadata, descriptions, and (when available) captions/transcripts — greatly improving analysis quality.
How to get a YouTube Data API v3 key (step-by-step):
Note: Most light-to-moderate usage falls within the free quota. Heavy usage may require linking billing.
Possibly — it depends on user demand and feedback. Potential Pro features could include custom text evaluation, bulk processing, advanced reports, white-label mode, and priority support. A Pro edition may be developed if interest is strong enough.
