🥇 Introducing GPT‑5.4

Introducing GPT‑5.4 — simonwillison.net · 7h ago · 🤖 AI / ML

OpenAI has released two new API models, gpt-5.4 and gpt-5.4-pro, now accessible via ChatGPT and Codex CLI, featuring an August 31st, 2025 knowledge cutoff and a 1 million token context window. Pricing is slightly higher than the GPT-5.2 family, with additional surcharges for usage above 272,000 tokens. Benchmark results show that GPT-5.4 outperforms the specialized GPT-5.3-Codex model in all relevant coding tasks. The author speculates whether the Codex line will continue or if its capabilities have been fully merged into the main GPT-5.4 models. The main point is that GPT-5.4 sets a new standard for coding performance and context size in large language models.

💡 Why read this: Essential reading for developers and AI practitioners tracking the latest advancements in large language models, especially those interested in coding capabilities and context window improvements.

Clinejection — Compromising Cline’s Production Releases just by Prompting an Issue Triager — simonwillison.net · 4h ago · 🔒 Security

Adnan Khan reveals a sophisticated attack chain targeting the Cline GitHub repository, exploiting a prompt injection vulnerability in the title of a user-submitted issue. The repository used anthropics/claude-code-action@v1 for automated AI-powered issue triage, configured to allow Bash, Read, and Write operations whenever any issue was opened. This configuration enabled attackers to execute malicious code through prompt injection, compromising production releases. The incident highlights the risks of integrating AI agents with broad permissions into CI/CD pipelines. The key takeaway is the critical need for strict controls and prompt sanitization when deploying AI-powered automation in software development workflows.

💡 Why read this: Vital for security engineers and DevOps teams to understand emerging AI-driven attack vectors and how to mitigate prompt injection risks in automated workflows.

🥉 Agentic manual testing

Agentic manual testing — simonwillison.net · 1h ago · 🤖 AI / ML

Agentic manual testing focuses on coding agents that can execute the code they generate, distinguishing them from LLMs that only produce code without verification. The core principle is to never trust code output by an LLM until it has been executed and validated. Coding agents are capable of running their own code, confirming its correctness, and iterating to fix issues as needed. This approach enables more reliable and autonomous software development processes. The main point is that execution and verification are essential for trustworthy AI-generated code.

💡 Why read this: Crucial for AI engineers and developers seeking to build robust agentic systems that autonomously generate and validate code.

4. The mystery of the posted message that was dispatched before reaching the main message loop

The mystery of the posted message that was dispatched before reaching the main message loop — devblogs.microsoft.com/oldnewthing · 16h ago · ⭐ 20/30

A puzzling situation is examined where a posted message in a Windows application is dispatched before it reaches the main message loop. The explanation centers on the possibility that the message was dispatched directly, bypassing the usual queue processing. Technical details clarify how message dispatching can occur outside the main loop under certain conditions, such as explicit calls to dispatch functions. The article demystifies a subtle aspect of Windows message handling. The conclusion is that understanding message dispatch mechanisms is key to diagnosing unexpected UI behaviors.
