Just Use GPT-5.4 xhigh

🔑 Enhanced Key Takeaways

• •GPT-5.4 introduces native computer-use capabilities, enabling the model to parse screenshots and issue mouse/keyboard commands for operating software, achieving 75.0% on OSWorld-Verified benchmark surpassing human performance of 72.4%[2][3][5].
• •It features a massive context window up to 1.05 million tokens in API and Codex, with tiered billing doubling rates beyond 272K tokens[3][5][6].
• •Enhanced vision supports full-fidelity image input up to 10.24M pixels via 'original' detail level, improving document parsing to 0.109 error rate on OmniDocBench[2][3].

🛠️ Technical Deep Dive

• •Native computer use: Parses screen coordinates from screenshots to issue mouse/keyboard commands; 75.0% success on OSWorld-Verified benchmark[2][3][5].
• •Context window: Up to 1.05M tokens in Codex/API (experimental, tiered billing >272K tokens at 2x rate)[3][5][6].
• •Image input: 'original' detail level up to 10.24M pixels or 6000px max dimension; 'high' up to 2.56M pixels or 2048px[2][3].
