- It doesn't write great code.

- Occasionally has strange tics around asking for permission for obvious next-steps, implied actions, etc.

- It's very expensive, both in terms of tokens and % usage on subscription plans.

- Relatedly, effort level is unintuitive. Sometimes it seems like higher effort levels are actually cheaper due to not under-thinking and needing to correct work. But other times they are overkill and send the model into rabbitholes.

That said, it's fantastic as a code-reviewer or "hunter seeker". It's better at finding bugs than Fable and "Get this well articulated task done single-mindedly" is an Astra-shaped task.
