IMHO The harness must be used when running these experiments. The model vendors know best on giving the best harness with gpt 5.4 and codex or Claude code with opus 4.6 which makes a big difference if you are running any kind of agentic coding tasks.
I see both Claude and gpt to be neck and neck in coding. Every other model+harness is definitely 3-6 months behind. Right now codex seems to be the best in terms of solving complex bugs, long running tasks, much higher limits and even speed while Claude seems to do well in front end and their cli ux seems nice! Codex app is very good though (wish it wasn’t electron as a memory hog but it’s good)
I wish oss models are good so that we don’t have to deal with either leading companies!
What we can argue about is if AI is truly transforming lives of everyone, the answer is a no. There is a massive exaggeration of benefits. The value is not ZERO. It’s not 100. It’s somewhere in between.
At the end of the day, it’s yet another tool that people can use to help their lives. They have to use their brain. The culture of seeing doctor as a god doesn’t hold up anymore. So many people have had bad experiences when the entire health care industry at least in US is primarily a business than helping society get healthy.
