gpt-6-sol
GPT-6 Sol API pricing.
OpenAI's mid-tier GPT-6 at $2 input and $10 output per 1M tokens, one fifth of Astra. Above 272K prompt tokens the whole request bills $4 / $15. Image input, tool calling, and reasoning. See the GPT-6 Sol API pricing notes.

Cost neighbourhood
Nearby routes, same workload.
Every comparison uses the same 100K-input / 10K-output turn. Changing route is a one-line model ID edit.
Price does not measure task quality. Check GPT-6 Sol benchmark evidence before optimizing on cost alone. For generation routes, see GPT Image 2.

Route notes
Questions before production traffic.
01How much does the GPT-6 Sol API cost?+
Through RouterPlex, GPT-6 Sol costs $2.00 per 1M input tokens and $10.00 per 1M output tokens — the vendor list price with 0% markup, billed per token from a prepaid balance you top up from $5. Cached input tokens are billed at $0.16 per 1M instead of the full input rate, which is most of the prompt on a repeated agent or coding loop. Base rate applies at or below 272K prompt tokens. Prompts above 272K are billed at $4 input / $15 output per 1M tokens for the whole request.
02What does one GPT-6 Sol agent turn cost?+
A 100K-token input with a 10K-token reply costs about $0.30 on GPT-6 Sol. That makes it the 45th cheapest of 60 comparable text models on RouterPlex, roughly 27.8× the cost of the cheapest option (DeepSeek V4 Flash).
03What is a cheaper alternative to GPT-6 Sol?+
Grok 4.7 from xAI is the closest cheaper model on RouterPlex — $0.26 per agent turn against $0.30 for GPT-6 Sol, at $2.00/1M input and $6.00/1M output. Both run on the same key and the same endpoint, so switching is a one-line model ID change.
04Is GPT-6 Sol cheaper than Gemini 3.1 Pro?+
Yes. Per agent turn, GPT-6 Sol costs about $0.30 against $0.32 for Gemini 3.1 Pro — 6% less.
05What is the context window of GPT-6 Sol?+
GPT-6 Sol supports a 922K token context window on RouterPlex, the 43rd largest of the 60 models that publish one.
06Can I use GPT-6 Sol with the OpenAI SDK?+
Yes. RouterPlex serves GPT-6 Sol through an OpenAI-compatible endpoint at https://api.routerplex.com/v1 — point any OpenAI SDK or tool at that base URL with your RouterPlex key and set model to "gpt-6-sol".
