<strong>A business that scales with the value of intelligence (7 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
OpenAI believes that its business model should scale with the value intelligence delivers. It introduced consumer subscriptions as people demanded more capability and reliability, created workplace subscriptions, and added usage-based pricing so costs scale with real work getting done. It has more recently applied the principle to commerce, helping people choose what to purchase next and explore products. Advertising follows the same arc.

<strong>The Bitter Lesson of Agent Frameworks (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
An agent is just a for-loop of messages. Agent frameworks aren't required. Models only need a complete action space, a for-loop, an explicit exit, and context management. Every abstraction is a liability, and every 'helper' is a failure point. The less you build, the more it works.

<strong>On the Coming Industrialisation of Exploit Generation with LLMs (7 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Agents built on GPT-5.2 and Opus 4.5 autonomously generated over 40 distinct working exploits for a zero-day QuickJS vulnerability across multiple scenarios, solving complex exploitation tasks in under an hour and with modest token costs. The experiment suggests exploit development will soon be limited more by token throughput than human hacker expertise, meaning offensive cybersecurity tasks could scale like industrial processes. This shift implies both unprecedented threat automation and urgency for preparing defense strategies as LLMs move beyond code assistance into full exploit synthesis.

<strong>Benchmarking AI Agent Memory: Is a Filesystem All You Need? (6 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
An agent's memory depends on its architecture, tools, and the underlying model. You can always mix and match frameworks, tools, and models. Simple file system tools are sufficient for a well-designed agent. More complex memory tools can be plugged in via MCP or custom tools.

<strong>The A in AGI stands for Ads (9 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
OpenAI is not dying or running out of money. While it has created a crazy circular economy, it's unlikely that it is looking to be acquired. Ads are the key to unlocking profitability. This article attempts to model OpenAI's expected annual revenue per user by understanding what it is actually building and how it compares to existing ad platforms.

<strong>The Code-Only Agent (17 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Building an agent can be overwhelming. The ecosystem pushes developers toward complexity and the 'right' way to do things. This post explores a prompting pattern where agents create and run code as a response to every prompt. In this framework, agents can't do anything productive without writing code. This method produces a code witness of an answer, codifying the work in a very literal sense. It forces agents to produce proofs, run proofs, and interpret proof results.
