Right! it seems obvious why: Both these companies want to dogfood their own coding models and stop paying competition.

You can also read this as diminishing returns / AI isn't good enough, etc, but the simplest explanation is that they don't want to send money to Anthropic.

This, and in addition to dogfooding, incentivizing employees to be more effective with the cheaper models. A lot of problems don't need anything fancy, but it takes more brain power and engineering effort to make that work. By default humans will take the path of least resistance if it's available.

This is likely the future as well. Down the road, every company will have their own internal coding models.

Does MS have coding models?
