Claude Opus 5 in one word is worst

Claude Opus 5 is consuming way too many tokens and too much time for simple coding tasks. Is anyone else experiencing this?

I’ve been using Claude since the early Opus models, but my experience with Opus 5 has been frustrating.

A simple sidebar highlight change recently consumed around million tokens, reached nearly 400K context, and took about 35 minutes. My actual project/skills context is only around 65K tokens.

The result is that work that should take hours is sometimes taking days. It also makes the Max 5x plan feel extremely expensive.

I don’t need the most powerful model like Fable 5.1 for every small development task, but I’m not sure what the best alternative is now.

For developers using Claude:

  • Are you seeing similar token/context usage?
  • Which model are you using for app development?
  • Any tips to reduce token consumption?
  • Is Anthropic planning a model better suited for fast, everyday coding?

Would really appreciate suggestions from fellow developers and especially any insight from the Claude/Anthropic team.
