That's like saying "somewhere between Eliza and Haiku 4.5". Haiku is not even a so-called 'reasoning model'.¹
¹ To preempt the easily-offended, this is what the latest Opus 4.6 in today's Claude Code update says: "Claude Haiku 4.5 is not a reasoning model — it's optimized for speed and cost efficiency. It's the fastest model in the Claude family, good for quick, straightforward tasks, but it doesn't have extended thinking/reasoning capabilities."
> Claude Haiku 4.5, a new hybrid reasoning large language model from Anthropic in our small, fast model class.
> As with each model released by Anthropic beginning with Claude Sonnet 3.7, Claude Haiku 4.5 is a hybrid reasoning model. This means that by default the model will answer a query rapidly, but users have the option to toggle on “extended thinking mode”, where the model will spend more time considering its response before it answers. Note that our previous model in the Haiku small-model class, Claude Haiku 3.5, did not have an extended thinking mode.

Maybe "Qwen3.5 122B offers Haiku 4.5 performance on local computers" would be a more realistic and defensible claim.
