Frequently asked questions

How much does the GPT-5.5 API cost, and how much does it save versus the official API?

As of 2026-08-26, Wokey lists input at $0.5 per 1M tokens and output at $3 per 1M tokens; the official references are $5 and $30. That is 90% lower for input and 90% lower for output. Request-time pricing controls settlement, and the vendor pricing source is linked on this page.

Which API forms does GPT-5.5 support, and how do I call it through Wokey?

GPT-5.5 supports /v1/chat/completions (Chat Completions requests) and /v1/responses (Responses requests). Set the API base URL to https://api.wokey.ai, authenticate with a Wokey API key, and use the canonical model ID gpt-5.5; you can start with /v1/responses. The Send a request section includes a curl example for every supported API form.

What are the context window and maximum output for GPT-5.5?

The catalog context window is 1,050,000 tokens and the maximum output is 128,000 tokens. These are separate limits, and a request must also satisfy the upstream constraints in effect when it is processed.

How are cache reads and cache writes priced for GPT-5.5?

Cache read: Wokey lists $0.05 per 1M tokens and the official reference is $0.5 per 1M tokens. Cache write: the vendor does not publish a separate meter, so Wokey also shows — as the public price.

How do GPT-5.5 and GPT-5.6 Sol differ in price and context?

In this price snapshot, GPT-5.5 lists input/output at $0.5 / $3 with a 1,050,000-token context window; GPT-5.6 Sol lists $0.5 / $2.5 with a 1,050,000-token context window. This is a factual price-and-capacity comparison, not a quality ranking; also compare their supported API forms and capabilities.
