## FAQ

**How much does the GPT-5.6 Terra API cost?**

Officially $2 per 1M input tokens and $12 per 1M output tokens, with cached input at $0.20. With the flat 50% apiToken.sale discount that is $1/$6.

**Terra or Sol?**

Terra is the balanced default for most workloads: during the Sol promotion it is 50% of Sol input and 60% of Sol output. Route only the hardest reasoning to gpt-5.6-sol. Both run on the same key, balance and endpoint.

gpt-5.6-terra. Point any OpenAI-compatible client at https://router.apitoken.sale/v1 and send it as the model parameter.
