Why Are These Platforms So Cheap?
Understanding the reasons behind third-party API platform price advantages
Third-party API platforms generally source their models through three channels:
1. Official Platforms
The API platforms of the model providers themselves, such as OpenAI Platform, Claude Developer Platform, and Google AI Studio. Prices are at official rates — the most stable and reliable option.
2. Cloud Service Providers
Some cloud providers have partnerships with model providers and deploy these models on their cloud platforms, such as Amazon Bedrock, Microsoft Azure Foundry, and Google Vertex. Thanks to promotional offers from these cloud providers, prices are generally slightly lower than official platforms (around 80-90% of the official rate).
3. Official Subscriptions and Third-Party Reverse Engineering
The two above are legitimate pay-per-token purchases, which leaves little room to push prices down. The core reason behind these platforms' low prices is the two sources below. Both are forms of "reverse engineering" — using technical methods to resell model quotas from non-API channels to users:
- Official subscriptions: Reselling quotas from official subscription plans such as Claude Max and ChatGPT Pro. These run on official accounts, so quality matches the official API while the per-unit cost is far lower. See: What are Claude Max and GPT Pro?
- Third-party reverse engineering: Reselling the model quotas that various third-party apps offer for free or at low cost. Prices are the lowest, but quality does not match official subscriptions. For detailed principles and sources, see: What are reverse groups?
Price vs. Quality Trade-offs
The experience varies significantly across different sources:
- Official API / Cloud Services: Best quality and stability, but higher prices
- Official subscriptions (e.g., Claude Max): Quality matches the official API, low prices (around 10-20% of official), but can stop working at any time
- Third-party reverse engineering: Lowest prices (1-10% of official), but quality is not as good as other channels and can stop working at any time
The instability of reverse channels and official subscriptions is also the main reason why platform prices fluctuate frequently. For this reason, we developed GetCheapAI.com, which aggregates price data from major platforms so users can stay informed about the latest pricing.
