Opennan, OpenAI, and OpenAny are three separate and unrelated companies. Opennan is an independent AI API marketplace that resells video, image, voice, music, text, and 3D models from many different makers through one API key. OpenAI is the company that builds models such as GPT Image and Whisper and sells them directly. OpenAny is a different marketplace with no connection to Opennan or OpenAI.
What each company does
Opennan
Opennan is operated by Silent Partner Technology Co., Ltd., registered in Thailand (Reg. No. 0205568045800). It provides access to 64 models from makers including Alibaba, ByteDance, Google, Kling, OpenAI, Meta, NVIDIA, and others, all through a single API key and a single prepaid USD balance. Categories covered are video, image, voice, music, text, 3D, and Roblox. You pay per call with no subscription. Where a model maker publishes an official API price, Opennan lists both prices side by side and sells at or below the official rate. Failed runs are refunded automatically, as stated on the pricing page.
OpenAI
OpenAI is the company that builds and sells its own AI models, including GPT Image 1.5, GPT Image 2, and the Whisper speech-recognition models. It sells these models through its own direct API. OpenAI does not own, operate, or fund Opennan. The Opennan about page states this directly:
Opennan is an independent AI API marketplace. It is not OpenAI and is not affiliated with OpenAI.
OpenAny
OpenAny is a separate AI marketplace unrelated to Opennan and unrelated to OpenAI. The name sounds similar but the company is distinct. No OpenAny page was among the sources reviewed for this article, so no specific claims about OpenAny pricing, features, or model counts are made here.
Opennan prices vs OpenAI official prices for OpenAI-made models
Opennan lists some OpenAI-made models on its marketplace. The pricing page shows both the Opennan price and OpenAI's published official price for each one. The table below reproduces those figures exactly as listed there.
| Model | Opennan price | OpenAI official price | Unit and conditions |
|---|---|---|---|
| GPT Image 1.5 | $0.026 | $0.034 | per image, Medium quality |
| GPT Image 2 | $0.039 | $0.053 | per image, Medium quality, 1K resolution |
| Whisper Large v3 | $0.000585 | $0.006 | per minute, billed per started minute |
| Whisper Large v3 Turbo | $0.00026 | $0.006 | per minute, billed per started minute |
OpenAI also sells these models directly at its own published prices. The figures above are what Opennan charges on its marketplace for the same models. Opennan is pay-per-call from a prepaid balance with no plan required.
Using the Opennan API
The Opennan API docs describe a REST interface at https://api.opennan.com and an MCP interface. One key covers every model category. You pick a scope when creating a key: api for everything, or narrower scopes such as api:video, api:image, api:text, api:voice, api:music, or api:3d.
Most generation calls return a task immediately. You poll GET /v1/tasks/{id} until the status reaches succeeded or failed. On failure the charge is refunded. Text models use the OpenAI Chat Completions format, so an existing OpenAI SDK client works after one change:
client = OpenAI(base_url="https://api.opennan.com/v1", api_key=os.environ["OPENNAN_KEY"])
Some tools require no key and no balance. Song to MIDI, Roblox clothing, and a Roblox player's public look are free, limited per IP address. The models page lists all 64 models with their current prices and status.
Summary of differences
- Opennan is a reseller marketplace. One key, 64 models from many makers, pay per call, no subscription, failed runs refunded, prices at or below each maker's official rate where one is published. Operated in Thailand by Silent Partner Technology Co., Ltd.
- OpenAI builds and sells its own models directly through its own API. It has no ownership stake or operational role in Opennan.
- OpenAny is a separate marketplace with a different owner. No pricing or feature details from an OpenAny source were reviewed here.
If you use models from multiple makers and want one key and one balance for all of them, that is what Opennan is designed for. If you need a model that only OpenAI sells directly, you would use OpenAI's own API for that model.
