Verify Prompt Cache

  1. Keep the shared prefix of long prompts identical and reuse context according to the selected API’s cache rules.
  2. Check input_tokens_details.cached_tokens; zero means no cache reads were recorded for this call.
  3. Uncached input = input_tokens minus cached tokens. Price each bucket separately and add the output charge.

Frequently asked questions

How much does the GPT-5.6 Sol API cost, and how much does it save versus the official API?

Wokey lists input at $0.44 per 1M tokens and output at $2.2 per 1M tokens; the official references are $4 and $20. That is 89% lower for input and 89% lower for output. Request-time pricing controls settlement, and the vendor pricing source is linked on this page.

What is the GPT-5.6 Sol API model ID?

The model ID for GPT-5.6 Sol on Wokey is gpt-5.6-sol. Use it exactly as written in the request body's model field or in your client's model setting (for example ANTHROPIC_MODEL in Claude Code, or model in the Codex CLI config.toml); GET https://api.wokey.ai/v1/models also lists it.

Which API forms does GPT-5.6 Sol support, and how do I call it through Wokey?

GPT-5.6 Sol 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-5.6-sol; you can start with /v1/responses. The Send a request section includes a curl example for every supported API form.

How do I use GPT-5.6 Sol in Codex CLI?

Codex CLI calls GPT-5.6 Sol over the Responses protocol. Add a model_provider to ~/.codex/config.toml with base_url = "https://api.wokey.ai", wire_api = "responses", and env_key = "OPENAI_API_KEY"; set model to gpt-5.6-sol and put your Wokey API key in OPENAI_API_KEY. The Codex CLI guide has the full config.

What are the context window and maximum output for GPT-5.6 Sol?

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-5.6 Sol?

Cache read: Wokey lists $0.044 per 1M tokens and the official reference is $0.4 per 1M tokens. Cache write: Wokey lists $0.55 per 1M tokens and the official reference is $5 per 1M tokens.

How does calling GPT-5.6 Sol through Wokey differ from OpenRouter?

Wokey lists GPT-5.6 Sol at $0.44 input / $2.2 output per 1M tokens, against an official reference of $4 / $20. OpenRouter states it adds no markup on inference and charges its fee when you buy credits (5.5% by card). Wokey carries a curated set of models and has no per-provider routing parameters, so OpenRouter fits better if you need a wider catalog. The OpenRouter alternative page has the full comparison.

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

In the published price comparison, GPT-5.6 Sol lists input/output at $0.44 / $2.2 with a 1,050,000-token context window; GPT-5.6 Terra lists $0.2 / $1.2 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.
