We believe in domain-specific models and domain-specific harnesses. At Callstack, we've been investing in both.
Excited to bring you the first piece of a broader family we're building. More to come!

Announcing Apex: agentic coding model for mobile and web, specialized in React.
We built Apex from a single idea: can an open-weight model deliver frontier-level performance at lower cost?
Yes. Apex is SOTA in React Native and Next.js.

Trying to force an LLM into perfectly deterministic behavior misses what it does best. Jakub Kuzimski shows how Allegro built a software factory around structured specifications, specialized agents, and explicit decisions instead.

A general-purpose agent can take on more than isolated coding tasks. Nick Miller shows how Grok Bot uses a cloud computer, company context, and familiar tools to handle long-running work across research, communication, and software delivery.

Agents can execute the same prompt-based skill again and again, spending tokens each time. Kent C. Dodds argues that repeated work belongs in deterministic software and demonstrates Kody, a personal software ecosystem designed to let any agent discover and run reusable capabilities.

Software development is moving from hand-written implementation toward systems where engineers direct agents, shape context, and judge the result. In the Agent Conf 2026 keynote, Mike Grabowski and Michał Pierzchała share how @callstackio is adapting to that shift.

Levan’s talk is now ou YT
When models get smarter so fast, how do you even design a product around them?
Shared how we do it at Rork in my @AgentConf talk!
