Use case
GPT-6.1 Sol tool calling
tool calling notes for gpt-6.1-sol: the rate card, a worked volume, and when to send this ID. A sample of 1 million input tokens plus 200 thousand output tokens is about $0.400 on corouter (input $0.200, output $0.200).
Tool definitions count as input
Tool JSON schemas count toward input tokens. Input for gpt-6.1-sol is $0.200. More tools and longer schemas raise the input bill. The output rate does not change.
GPT-6.1 Sol matches the GPT-6 Sol list rate and is a separate model ID. Send gpt-6.1-sol when the client names that ID rather than gpt-6-sol.
Set it next to a lower output rate
GPT-6.1 Sol (gpt-6.1-sol) lists at $2.00 input and $10.00 output per million tokens. corouter bills $0.200 input and $1.00 output. Context is 1.1M.
A sample of 1 million input tokens plus 200 thousand output tokens is about $0.400 on corouter (input $0.200, output $0.200).
