Price gap
GPT-6.1 Sol and GPT-6 Sol share the same corouter input and output rates: $0.200 input and $1.00 output. The difference in this pair is the model ID, not the rate card.
Window and modalities
Both windows are 1.1M. GPT-6.1 Sol is listed with these modalities: Chat, Reasoning, Code, Vision. GPT-6 Sol is listed with these modalities: Chat, Reasoning, Code, Vision.
When to send gpt-6.1-sol
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.
Both are OpenAI IDs. The field you change is model: gpt-6.1-sol or gpt-6-sol.
When to send gpt-6-sol
GPT-6 Sol keeps the 1.05M window and lists well below Astra on both input and output. Send gpt-6-sol for the same request shape at the lower GPT-6 rate.
Both are OpenAI IDs. The field you change is model: gpt-6-sol or gpt-6.1-sol.
