Price gap

On output, GPT-6 Sol is lower: $2.00 on corouter versus $3.00 for GPT-5.4, about 1.50×. Input is $0.400 versus $0.500.

Window and modalities

Both windows are 1.1M. GPT-5.4 is listed with these modalities: Chat, Reasoning, Vision. GPT-6 Sol is listed with these modalities: Chat, Reasoning, Code, Vision.

When to send gpt-5.4

GPT-5.4 is the general 1.05M GPT row beneath the Pro rate and above Mini. Send gpt-5.4 for chat, reasoning, and vision without the Pro multiplier.

Both are OpenAI IDs. The field you change is model: gpt-5.4 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-5.4.
