Ben's BitesHey folks,
I’m back from holiday and straight back to messing around building. I’ve been kinda obsessed and enamoured with the demos from tldraw. It’s a free canvas/whiteboard app but their offline app (recently updated) is cool because agents can do all sorts with it; create visualisations to explain stuff, make games, interactive blog posts and a ton of other stuff.
Like turning our logo into a little animating mascot. He’s called ‘bites’ btw.
or little widgets like a timezone checker

It’s boring, I don’t read it and I sure as shit don’t do enough (anything?) with it. So if it’s visual and all on one canvas, maybe I will?
My idea here is to create a little ‘one-stop’ canvas for some widgets I use regularly as well as showing me my todos/emails to sort and things like that. I’m then planning on making my personal site an interactive canvas too, then some more explainer-like stuff too.
And maybe I’ll get the mascot hooked up to an agent so i can drag him to my todos and ask him to do stuff…
I’ll share more soon 😊
Ben’s Bites is brought to you by Ability AI
This startup runs on 17 AI agents - and open-sourced the platform. Marketing, client health, competitive intel, finance - real ops, not demos, with every agent action git-tracked and a human approving anything external. Agents you own, not rent. Apache 2.0: github.com/Abilityai/trinity
Headlines
Claude Opus 5 is out - Anthropic says it gets close to Fable 5 at half the price. Claire hated using Opus 5, but when asked to rank model outputs in a blind test, she ended up rating it first.
Every’s review lists some behaviours that might explain this: it argues, stops early and fights the skills people built for older models.
And maybe we are overprompting it.
Anthropic says it removed more than 80% of Claude Code’s system prompt for Opus 5 and Fable 5 with no measurable coding-eval loss.
ChatGPT Voice can now run the ChatGPT desktop app. You can use it in ChatGPT Work and Codex both; just start a “Voice” session and speak to it. It can create new sessions for individual tasks and then report the results to you in the main thread. It feels a lot like OpenClaw with voice.
I didn’t have a great time using ChatGPT Voice for “serious” work. The delegation of tasks to new sessions via ChatGPT Voice doesn’t feel as smart as doing it in a chat with 5.6 Sol in Codex. Maybe it’s the lack of control on what models/thinking level is used for each new session.
I imagine Voice to work great for productivity type tasks, checking emails, creating draft replies, pull some info from a dashboard and create a chart etc.
For serious work, I still prefer using a speech to text app (currently using one I built — optionafk.com) and sending that to the agent of my choice with full control over model/thinking effort.

Also, I wouldn’t blame you if you missed it, but Claude also has a voice mode. Till now, it could only use Haiku, but now it can use Sonnet and Opus as well as call multiple tools like Gmail, Calendar and Slack mid-conversation. I don’t remember when I last used Claude’s chat option. It’s been Claude Code for a long time now.
Kimi K3’s weights and technical report are out. It’s already available in Droid at 50% off until 10 August.
Following rumours that the US might ban companies from using Chinese open-weight models, NVIDIA’s CEO Jensen Huang made his first-ever post on X - a long statement backing open-source AI. Over the weekend, everyone signed that statement (OpenAI, Google, Microsoft and 150+ more) - except Anthropic.
Of course, that led to some backlash, and Anthropic did what it does: published an essay to save face, saying it never pushed for an open-weights ban. The reaction to it is people calling Anthropic out on their hypocrisy — they are okay with open models as long as they are cute little 8b toys, but not if they are “big, dangerous models” (to Anthropic’s business).
