What is an AI Watermark? (And should you avoid them?)
Is what you are reading written by a human, or by AI? (Spoiler alert: I write all my newsletters by hand. I've been sending weekly newsletters for nearly two decades, because I enjoy writing weekly missives - none of this was written by AI.) A watermark declares authenticity. It's like a subtle version of a cattle brand - it can be added to paper documents to prevent counterfeiting, show provenance, or identify the publisher or manufacturer. Adding watermarks to AI [...]
Clone Your Writing Voice with an AI Voiceprint
This past Monday I presented at the Christchurch AI Meetup. We meet the 2nd Monday of every month at EPIC Innovation. If you are a local, you can join our Meetup group to get notified of upcoming events. You can watch the replay here. We had 3 speakers presenting on the theme of Marketing & Comms with AI. During my presentation, Create a Brand Voice Kit with AI, I demonstrated how to take a Voiceprint. This analyses the tone, style, and cadence of your writing [...]
The New GPT-Voice is a New AI Conversation
If you tried ChatGPT Voice before, and you were unimpressed, try it again. The previous Voice experience was interesting, but awkward. It interrupted pauses. It misread the end of a sentence. It responded too quickly when you were still gathering your thoughts. Talking to it felt like you had to manage an over-caffeinated friend, who was too enthusiastic to contribute, desperate to finish your sentences. The new ChatGPT Voice is powered by GPT-Live. OpenAI says it has been designed for [...]

Open Source vs Closed Source AI Models
The conventional wisdom has been: open-source models are 3-6 months behind frontier models. If you wanted best-in-class reasoning, you had to pay for your tokens through a Frontier model. You could pay through a subscription (all-you-can-eat) or via an API (pay-as-you-go). With the release of agent harnesses like OpenClaw and Hermes, you can switch models with a simple slash command. The same agent will hold the same personality, and the same instructions, but between one prompt and another, you could switch [...]
☀️ / 🌍 / 🌙 Which GPT-5.6 Model should you pick?
There's been lots of releases in July 2026. First, Anthropic said after Fable 5 was (re)-released, it would go onto the API, and paid subscribers could only use it via API or usage credits (making it pay-as-you-go, instead of all-you-can-eat) after 7 July. Then, OpenAI released GPT-5.6, with 3 reasoning levels, and your choice of effort : Fable 5 has been re-added to the subscription plan twice while Anthropic sees cancellations as users migrate to GPT-5.6. Sol, Terra, and Luna. Which one do you pick? [...]
