Looks like we are at the end of the Fable-level model at subscription pricing. It will be double the cost at paid-per-token usage. I’m counting on the other models to compete now at the subscription level and I need my harness to be agnostic. What do you use?

#3I just stay with Opus-4.8 - because it's not like that Opus is not capable of solving all my daily tasks. It just works fine. Fable is of course better, especially on paper, but it didn't do wonders for me. I feel like Anthropic can't continue just making better models all the time, they will have to care efficiency more and more because that is what they lack the most. Just compare it to any other LLM, they are all way more efficient which means they are way faster and cost less money per token. So for me it's just wait and relax - use Opus-4.8 until Anthropics models hopefully become cheaper and faster.

#4Crush is pretty nice. It’s become my daily driver for personal projects. They maintain a list of supported providers so most of the time no configuration is needed.
OpenCode is also fine but more finnicky - if you’re ok with desktop apps, give OpenChamber a try.

What's the difference in crush and opencode? What do you mean by finicky?

#8I’d optimize for provider-agnostic tooling now. If Fable-style subscriptions become token billing, switching between Claude, GPT, Gemini, and local models matters more than finding one perfect plan.

#9I build VT Code, a Rust coding agent, from it, you can easily switch LLM providers/models and various configs like effort and plan/build/auto mode. Fable 5 included.

#10imo model switching only works if you normalize outputs and keep model specific weirdness behind well designed adapters
