And it's all measured in "intelligence", a completely meaningless term. For coding i'd be much more interested in how much context actually works, what the complexity of algorithms it can understand and create is, for what languages. How much it manages to follow existing structures or that is just adds ad-hoc machinery to pass the test, etc etc.

A smaller model in the same generation will never be the same as a bigger one, assuming this is a smaller model, and the same generation, as naming implies, it will not be comparable, it might be on the benchmarks, even on the benchmarks that matter, but the whole story should also give the drawbacks.

It's still insane that they stopped showing you all the tokens you pay for. They could inflate the billed reasoning token amount by a lot before it would raise any eyebrows.

Internet Ad business has been like that for a long time with bot click & Co.

Totally hand-wavy and non-objective ... just like how employees are billing their employers.

It's all Gacha for business.

Yeah, you might get away with a singular 'wrt' with some consternation, but two?

Preserve context in the lead chat - let the subagents fill up their own contexts then only return the necessary information.

Why hire a junior developer if you have a perfectly competent senior developer already on your team?

You can do a code review on a "less capable" model that costs less, and the key model gets its output / summary, then you can have that model build a plan, and feed it to cheaper models. It's a more efficient approach than just running everything through Opus, and now that Sonnet is a lot better I'll probably use them more frequently, one thing to note is don't ask it to spin up endless subagents, I'd cap it to 2 or 3 at a time, otherwise, yeah you'll hit your limit extremely quickly.

Because two agents are faster than one.

The models get dumb as context fills. Subagents allow them to accomplish a task with minimal context rot. You can also use cheaper models for subagent tasks

Time is money. Parallelism is very helpful optimising one to get the other.
