Review
GPT-5.4 excels at strong reasoning and programming, but shows marked weaknesses in autonomous agent workflows. It is recommended for projects requiring deep reasoning and code quality, but is unsuitable for systems demanding high agent autonomy.
Strengths
- Strong logical reasoning, handling complex problems, multi-step reasoning, and long reasoning chains well
- Strong programming capabilities, effective in code generation, code review, debugging, and refactoring
- Solid general conversation, balancing high precision with a natural tone
Weaknesses
- Weak in autonomous agent tasks; not optimized for complex autonomous workflows
- Limited adaptability to abrupt requirement shifts or continuous operation
- Higher cost than compact models for simple tasks; context length may be limiting
Use cases
Complex logical analysis, mathematics, multi-tiered problem-solving, and deep researchSoftware development, high-quality code review, and architectural decisionsContent creation, brainstorming, and writing tasks requiring high precision and detail
