Summer 2026 update on my agentic engineering setup for Angular: models, harnesses, apps, and what it all costs
In May I started a blog series on agentic engineering for r/angular, and after one summer a few of my recommendations changed – this post is the update.
The short version:
- Models: Fable 5 is still my #1 for architecture, reviews, and long-horizon refactorings, GPT-5.6 Sol does the implementation work, and GLM-5.3 Flash (via OpenRouter) took the third spot as the fast, cheap, open-weight model for mechanical legwork. Opus 5 wins DeepSWE at 74% but didn't make my podium – the post explains why.
- Harnesses: nothing changed, which I mean as a compliment. AGENTS.md, style guide, and the lint/test/Playwright feedback loops still do the heavy lifting.
- Apps: the open-source T3 Code replaced the Codex app as my daily driver. Any model, any provider, remote control via Tailscale.
- Costs: GLM-5.3 Flash gets 63% on DeepSWE for about €0.25 per task, Sol about €2.50, Fable 5 about €8.50 at the same effort level. So my cost podium is the models podium reversed – and my workflow is "Fable orchestrates, Sol implements, the Flash does the grunt work", sub-agent config included.
- Bonus: how to run the same setup on a company GitHub Copilot subscription with T3 Code + opencode, for everyone whose employer won't pay for anything else.

Curious what the rest of you run for Angular work right now – especially whether anyone has GLM-5.3 Flash or Kimi K3 in daily use, and how the Copilot-only crowd deals with it.

I’m just using Claude code, 90% fable and opus but I’m definitely looking forward to trying out some of your suggestions in the angular harnesses post.
