Models with more mileage
early stages of becoming a developer.
The newsletter for the technically curious. Updates, tool reviews, and lay of the land from an exited founder turned investor and forever tinkerer.
Hey folks,
GPT-5-Codex has a mini variant now. It’s not that far from the big brother on SWE-Bench Verified. The model is only available in Codex CLI and IDE extensions. API is coming soon, though. Codex-mini gives you 4x the mileage of Codex. Also, all paid ChatGPT plans now have double the rate limits for Codex.
Kimi K2 Thinking is an open-weights model that is now #1 on many benchmarks like HLE & BrowseComp across all models (not just open ones). Kimi models seem to have really great writing taste, while being great at coding tasks and being cheaper.
So the trend of models that go further continues with two options: closed-source RL-ed models (Composer, SWE-1.5) and huge MoE open models (GLM, MimiMax, etc.)
Replit now lets you add AI features to your apps with zero extra setup. No need to make developer accounts, get API keys, etc. You can use 300+ models, including Gemini, OpenAI, Claude or even open-weights models from OpenRouter. The AI cost is billed against your credits. Smart move tbh.
There’s a new stealth model on OpenRouter named Polaris Alpha, which looks a lot like GPT-5.1. I also caught a few leaks for Nano Banana 2, mostly creating realistic images of news channels.

Droid updates - I’ve been on a pretty steep slope learning to be a bit of a developer 😬. I shipped our new docs site, run the changelog process, started making guides (with help from Ian Nuttall) and lots more. We’ve got a new (super simple) MCP feature to add/remove/enable and disable MCPs, plus some big new things coming out the next couple of weeks. You can join the discord to hear about early access 👀.

⚙️ Tools and demos
Voices has the best voices for AI-assistants. BMW found their voice with Voices–join the product launch on Nov 13, 1pm ET to see how.*
DeepWiki - Understand any GitHub repo with navigable and comprehensive docs generated on demand.
Voice Conversion by Hume - Generate the same pacing, pronunciation, and intonation with one recording across any voice you choose.
Papiers - A new interface for arXiv papers with mindmaps, children/parents of a paper, X discussion surrounding it and more.
Parse - Build an API for any website in minutes, 100x faster than browser using automations.
Swipe by vectors.fun - A new way to steer image models. Start with a prompt, swipe left/right to steer the model towards what you’re thinking of. (read more)
