What is CheaperInference?
CheaperInference is a marketplace for AI inference. The service buys up spare compute capacity from large model providers and specialised infrastructure operators, and resells it through a shared, OpenAI-compatible API. For users, little changes: requests, streaming, tools and response handling keep working in the existing format – only the base URL and API key now point to CheaperInference.
The provider promises three hard limits: prices never exceed the direct list price, there is no separate routing surcharge, and billing is per token – there is no monthly subscription. Accounts can be funded from $5.
ChatGPT or Claude? The dilemma behind an API
Anyone using AI models via API knows the drill: every provider wants its own account, its own billing, its own SDK. If you want to test ChatGPT (OpenAI) and then Claude (Anthropic), you open two accounts, fund both and maintain two sets of keys. The marketplace approach solves exactly that: one account, one balance, and the model is chosen per request.
As of 23 September 2026, the catalogue includes, among others:
- OpenAI: the gpt-5.x family (luna, terra, sol, 5.5, 5.4, Mini/Nano variants, Codex models, gpt-image-2)
- Anthropic: Claude Opus 4.5 to 5, Claude Haiku 4.5, Claude Fable 5 and 5.1
- Google: Gemini models
- DeepSeek: v4 Pro, v4 Flash and v4.1 Flash
- Z.ai: GLM-5.3 and GLM-5.3 Flash
- plus Llama (Meta), FLUX (Black Forest Labs), Kling/Kuaishou and voice models from ElevenLabs
Switching between ChatGPT and Claude is no longer an account switch – it is a parameter in the request.
How easy is the switch?
CheaperInference speaks the OpenAI protocol. In existing code, two values change:
baseURL: "https://api.cheaperinference.com/v1" apiKey: "<your CheaperInference key>"
Messages, tools, streaming and error handling stay unchanged. Documentation and the model overview live at platform.cheaperinference.com.
What does it actually cost?
Prices float with the capacity market, so the live catalogue is worth a look. The provider advertises savings of up to 60 percent; the discount column in the catalogue showed values between 15 and 45 percent on 23 September 2026:
| Model | Provider | Input per 1M tokens | Output per 1M tokens | Discount |
|---|---|---|---|---|
| gpt-5.6-luna | OpenAI | $0.17 (list: $0.20) | $1.02 (list: $1.20) | 15% |
| deepseek-v4.1-flash | DeepSeek | $0.26 (list: $0.30) | $1.02 (list: $1.20) | 15% |
| glm-5.3-flash | Z.ai | $0.10 (list: $0.15) | $0.35 (list: $0.50) | 30% |
| deepseek-v4-flash | DeepSeek | $0.18 (list: $0.30) | $0.72 (list: $1.20) | 40% |
| glm-5.3 | Z.ai | $0.77 (list: $1.40) | $2.42 (list: $4.40) | 45% |
That this is a living market rather than an empty shopfront is shown by the activity display: gpt-5.6-luna alone moved around 38 billion tokens in the last 24 hours.

Privacy and traceability
Anyone routing their prompts through third-party infrastructure should know what is stored where. CheaperInference explains its data boundaries in a dedicated overview: which metadata the marketplace stores, where caching can occur, and which routes run with zero data retention (ZDR) – requests without storage at the intermediary. On top of that, every request is individually visible in the history. For confidential data, the same rule applies as with any API: prefer ZDR routes and leave out personal data.
Who benefits – and who doesn’t?
Makes sense for developers and teams already working via API across multiple model families: one balance replaces several provider accounts, the price advantage is tangible, and the way back (swap the base URL again) is always open. Even heavy users of a single model may find the discount worth the switch – with the guarantee of never paying above list price.
Less useful if you work exclusively through the ChatGPT or Claude chat frontends – CheaperInference is a pure API for developers, not a chat subscription with an interface. Regulation or company policy can also argue against third-party intermediaries; the provider lists its subprocessors publicly.
Conclusion
CheaperInference solves two problems at once: the account sprawl between ChatGPT, Claude and the other model families – and the price per token. The entry hurdle is minimal at $5 and two lines of code, and usage-based billing without commitment keeps the risk bounded. Anyone toying with switching between OpenAI and Anthropic – or using both – gets both from one hand here, and pays no more, often noticeably less than buying direct.
