Every request is metered at the official rate first, then the flat 50% B2C discount is subtracted before it touches your prepaid balance. Context window: 872K tokens. Max output: 128K tokens. Reasoning efforts: none, low, medium, high, xhigh, max.
Best for
- Interactive and agentic coding with explicit effort control.
- Everyday reasoning, tool calls and structured JSON output.
- Image understanding at a lower price than Astra.
Good to know
- This service uses Sol's Codex subscription limits: 872K maximum context. The larger direct OpenAI API window does not apply here.
- Discovery reports 872K total context, 128K output and 744K conservative input.
- Above 272K input tokens, the whole request uses 2× input/cache rates and 1.5× output rates. Fast (priority) uses 2× the applicable API rates.
- Codex-specific ultra delegation is not advertised.
