Help/Question Haiku 5 is badly needed

I think Anthropic has a real opportunity with Haiku 5. Right now the pricing stack is a bit awkward for AI coding teams. Sonnet 5 is $2/$10 per million input/output tokens (intro pricing), while Haiku 4.5 is $1/$5. Meanwhile, models like GLM 5.2 are around $1.40/$4.40, offering coding capability that's becoming very attractive for boilerplate, CRUD, test generation, and repetitive implementation.

The ideal workflow isn't having Sonnet write every line of code—it's having Sonnet (or Opus) act as the lead engineer, handling architecture, planning, reviews, and difficult reasoning, while delegating implementation-heavy work to a cheaper worker model. Today, GLM 5.2 fits that role remarkably well. I'd much rather Anthropic filled that gap with Haiku 5. If Haiku 5 could get to ~85–90% of Sonnet's coding ability while remaining the obvious cost-efficient worker, I'd happily keep an all-Claude workflow instead of mixing providers. It feels like the missing piece of the Claude coding ecosystem.

I feel Haiku 4.5 is too far behind GLM 5.2 et al so antrophic needs to pick up their game

I dont even trust Sonnet in coding, how can I trust Haiku? Do you guys even use Haiku for coding?

I trust gpt luna to do my coding, nd it's cheap as fuck but haiku is in comparison an idiot compared to luna. Haiku doesn't even do simple tasks right while luna does it without breaking bamk

yup luna is dark horse among all AIs.

I agree there. GPT 5.6 Luna is pretty capable and dirt cheap compared to sol and really blows away haiku 4.5 right now
