As soon as tokens stop being subsidized I would not trust any harness made by a company that also charges for the compute.
Right now the interests align, but as soon as more tokens -> more profit (instead of more revenue and more losses) the perverse incentives will be too big to avoid.
It seems inevitable that open source harnesses will win. These companies would do better to just open source their harnesses.
An OpenAI subscription seems like a decent alternative for people using open source coding agents. It has usage limits too, but for $20/month it’s not bad.
Not that I disagree but I can imagine it's easy enough to ship implicit token increase (ratchet up the COT settings) on then backend
