Can Gimbix route to it first?
Not as a first-answer model through OpenRouter: no host returns token log probabilities for GPT-5.4. It can still be the model Gimbix falls back to when a cheaper model is unsure.

| Host | Input / output per 1M | Log probabilities | Uptime, last 30 min |
|---|---|---|---|
| OpenAI | $1.25 / $7.50 | no | 100.0% |
| Azure | $2.50 / $15.00 | no | 100.0% |

A host that lists log probabilities may still omit them; Gimbix checks each one before relying on it.
Cheaper models that can answer first
Models priced below GPT-5.4 that expose a confidence signal. Whether they answer your traffic as well is what a Gimbix pilot measures.

Questions
How much does GPT-5.4 cost?
GPT-5.4 lists at $2.50 per million input tokens and $15.00 per million output tokens on OpenRouter as of 2026-09-28. A typical chat reply of 2,000 input and 400 output tokens costs about $11.00 per 1,000 requests.
What is the context window of GPT-5.4?
1,050,000 tokens.
Can a cheaper model replace GPT-5.4?
Sometimes. Gimbix proves it on your own traffic before routing: the cheaper model must match GPT-5.4 on one half of your requests and make at most three answers worse on the other.
