Is GPT 5.4 the Opus 4.6 Killer?

Description

GPT‑5.4 in ChatGPT (as GPT‑5.4 Thinking), the API, and Codex. It’s our most capable and efficient frontier model for professional work. We’re also releasing GPT‑5.4 Pro in ChatGPT and the API, for people who want maximum performance on complex tasks. GPT‑5.4 brings together the best of our recent advances in reasoning, coding, and agentic workflows into a single frontier model. It incorporates the industry-leading coding capabilities of GPT‑5.3‑Codex⁠ while improving how the model works across tools, software environments, and professional tasks involving spreadsheets, presentations, and documents. The result is a model that gets complex real work done accurately, effectively, and efficiently—delivering what you asked for with less back and forth. In ChatGPT, GPT‑5.4 Thinking can now provide an upfront plan of its thinking, so you can adjust course mid-response while it’s working, and arrive at a final output that’s more closely aligned with what you need without additional turns. GPT‑5.4 Thinking also improves deep web research, particularly for highly specific queries, while better maintaining context for questions that require longer thinking. Together, these improvements mean higher-quality answers that arrive faster and stay relevant to the task at hand. In Codex and the API, GPT‑5.4 is the first general-purpose model we’ve released with native, state-of-the-art computer-use capabilities, enabling agents to operate computers and carry out complex workflows across applications. It supports up to 1M tokens of context, allowing agents to plan, execute, and verify tasks across long horizons. GPT‑5.4 also improves how models work across large ecosystems of tools and connectors with tool search, helping agents find and use the right tools more efficiently without sacrificing intelligence. Finally, GPT‑5.4 is our most token efficient reasoning model yet, using significantly fewer tokens to solve problems when compared to GPT‑5.2—translating to reduced token usage and faster speeds. https://openai.com/index/introducing-gpt-5-4/ Timestamp 0:00 Intro to GPT 5.4 0:30 Key Features of GPT 5.4 1:20 Enhanced Multimodality/Vision 2:07 Steerability and Efficiency 2:41 Performance Benchmarks 3:28 OS World Verified (Computer Use) 3:40 Web Arena (Web Browsing) 4:06 GDP Well (Real-World Tasks) 4:44 Browser Comp (Agentic Browsing) 5:27 SWEBench Pro 5:48 Toolthon (Agentic Tool Use) 6:35 Practical Use Cases and Demos 9:50 Availability 10:33 Conclusion ❤️ If you want to support the channel ❤️ Support here: Patreon - https://www.patreon.com/1littlecoder/ Ko-Fi - https://ko-fi.com/1littlecoder 🧭 Follow me on 🧭 Twitter - https://twitter.com/1littlecoder
