😸 Our HONEST review of GPT 5.4: They should've called it 5.5

Summary

OpenAI has released GPT 5.4, a new general-purpose model that integrates coding capabilities from its Codex line, along with document, spreadsheet, and computer navigation functions. Benchmarks show GPT 5.4 matching or exceeding human professionals in 83% of knowledge work tasks, operating a computer better than the average person (75% on OS World), and outperforming GPT 5.3 Codex on SWE Bench Pro for coding. It also achieves state-of-the-art results on Browse Comp (82.7%) and Tool Athlon (54.6%) for tool use. The model is available to ChatGPT Plus, Team, and Pro users, and for developers at $2.50 per million input tokens, half the price of Anthropic's Opus. Meanwhile, Anthropic, despite rapid growth and IPO preparations, has been labeled a supply chain risk by the Pentagon due to CEO Dario Amode's refusal to allow military use for mass surveillance or autonomous weapons.

Key takeaway

For AI/ML Directors evaluating foundational models, GPT 5.4's integrated coding, computer use, and knowledge work capabilities, combined with its competitive pricing, present a compelling option. Your teams should explore its "steerable thinking plans" feature to improve output quality and efficiency, especially for complex tasks, by correcting AI's approach before full generation. This shift could significantly impact development workflows and resource allocation.

Key insights

GPT 5.4 integrates advanced coding and computer use capabilities into a single, powerful general-purpose model.

Principles

• AI models can surpass human performance in diverse professional tasks.
• Early error detection in AI workflows saves significant time.

Method

To improve AI reasoning, ask the model to outline its thinking plan first, then correct its approach before it generates the full output. This technique works across various reasoning models.

In practice

• Use GPT 5.4 for integrated coding, document processing, and browser navigation.
• Implement steerable thinking plans for complex AI tasks like debugging or data analysis.
