kimmonismus · x · 2026-07-10
The author outlines GPT-5.6's performance, noting its strength in coding, browsing, cybersecurity, science, long-context, and agentic tasks. It achieves or approaches new SOTA levels across multiple benchmarks while completing tasks with fewer tokens, in less time, or at a lower estimated cost.
The post lists specific results from evaluations including Agents’ Last Exam, Terminal-Bench 2.1, BrowseComp, OSWorld 2.0, Artificial Analysis Coding Agent Index, and SEC-Bench Pro, pointing out that GPT-5.6 outperforms models like Claude Fable 5 and Claude Opus 4.8 on several benchmarks.
Furthermore, the author argues that the true highlight is the application-layer tool, ChatGPT Work. It integrates with docs, Slack, Notion, Microsoft 365, and Google Drive, seamlessly organizing scattered context into decks, documents, spreadsheets, dashboards, visualizations, and interactive explanations.
