Every request is metered at the official rate first, then your progressive B2C discount (60% at the start, up to 70% as cumulative top-ups grow) is subtracted before it touches your prepaid balance. Context window: 272K tokens. Max output: 32K tokens. Reasoning efforts: none, low, medium, high, xhigh, max.
Best for
- Agentic coding in Codex CLI, opencode and OpenAI-compatible tools.
- Hard reasoning with adjustable effort, up to the max level.
- Long multi-turn sessions with cached-input pricing.
Good to know
- gpt-5.6 is a convenience alias of gpt-5.6-sol — the same model at the same price.
- Text and image input, text output. SSE streaming on both Responses and Chat Completions.
- Requests above 272K input tokens bill at OpenAI long-context rates: 2× input and 1.5× output on the whole request.
How to use GPT-5.6 Sol
Create a free account, generate one key, and point any OpenAI-compatible tool at https://openai.api.apitoken.sale/v1 with model ID gpt-5.6-sol — Responses and Chat Completions both work, authenticated with Authorization: Bearer. New accounts include $10 of API usage at official prices — enough to test the model before topping up.
Frequently asked questions
How much does the GPT-5.6 Sol API cost?
Officially $5 per 1M input tokens and $30 per 1M output tokens, with cached input at $0.50. On apiToken.sale the same requests start 60% cheaper — from $2/$12 — and reach $1.50/$9 at the maximum 70% discount.
What is the model ID for GPT-5.6 Sol?
gpt-5.6-sol (gpt-5.6 is an alias of the same model). Use it with the OpenAI SDK, Codex CLI, opencode or any OpenAI-compatible tool pointed at https://openai.api.apitoken.sale/v1.
Does the same key really work for GPT and Claude?
Yes. One sk-pool key and one prepaid balance cover both surfaces: Anthropic Messages API for Claude models and the OpenAI-compatible API for GPT models. The same discount applies to both.
Run GPT-5.6 Sol on the OpenAI-compatible API at up to 70% off — instant key, prepaid balance, card or crypto.
