Less than two weeks after GPT-5.4 dropped, OpenAI followed up with two smaller variants: GPT-5.4 mini and GPT-5.4 nano. Both target high-throughput workloads — faster responses, lower cost.

GPT-5.4 mini approaches the full GPT-5.4 on several benchmarks and is a substantial step up from GPT-5 mini. Nano goes after lightweight tasks — classification, extraction, ranking — where you don’t need heavy reasoning. Both models support GPT-5.4’s tool calling and structured output capabilities.

OpenAI Releases GPT-5.4

OpenAI launched GPT-5.4, offering gpt-5.4 and gpt-5.4-pro API models, available in ChatGPT and Codex CLI.

Key updates:

Knowledge cutoff: August 31, 2025
Context window: 1 million tokens
Enhanced spreadsheet, presentation, and document handling
Outperforms GPT-5.3-Codex on benchmarks

This update isn’t about being “smarter”—it’s about being more practical. A million-token context handles most enterprise documents, and the focus on office scenarios shows they’re targeting the Microsoft 365 Copilot market. Not a technical breakthrough, but a strategic pivot.
