# gpt-5.4 — API, Pricing & Context Window

Use OpenAI's gpt-5.4 on Vivgrid: a 1.05M-token coding model with broad three-region acceleration (AMER, EMEA, APAC) and a unified, OpenAI-compatible API.

`gpt-5.4` is a high-capability OpenAI coding model that balances frontier-level quality with a more accessible price than `gpt-5.5`. Its **1.05M-token context window** comfortably holds large codebases, design docs, and long agent histories.

On Vivgrid it has the **widest acceleration footprint** of the GPT-5 family — geo-distributed across **AMER, EMEA, and APAC** — making it a strong default for globally distributed teams and agents.
