       | single year.

         | You have to be called Apple to get raving reviews for that.

         | This is the first low-key, silent feature rollout, treated like
         | "just another software update", with no hype or buzz
         | beforehand. Prior to this point, every other feature release
         | was pumped for weeks or even months with "leaks" from insiders
         | and deliberately getting people amped. I don't know if OpenAI
         | changed marketing tactics, or if they're in a new chapter in
         | some book, but this is a radical shift from what they were
         | doing before.

       | The prompt caching change is awesome for any agent. Claude is far
       | behind with increased costs for caching and manual caching
       | checkpoints. Certainly depends on your application but prompt
       | caching is also ignored in a lot of cost comparisons.

         | Though to be fair, thinking tokens are also ignored in a lot of

         | fewer thinking tokens for the same intelligence

       | Claude 4.5 Sonnet definitely struggles with Swift 6.2 Concurrency
       | semantics and has several times gotten itself stuck rather badly.
       | Additionally Claude Code has developed a number of bugs,
       | including rapidly re-scrolling the terminal buffer, pegging local
       | CPU to 100%, and consuming vast amounts of RAM. Codex CLI was
       | woefully behind a few months ago and, despite overly conservative
       | out-of-the-box sandbox settings, has quite caught up to Claude
       | Code. (Gemini CLI is an altogether embarrassing experience, but
       | Google did just put a solid PM behind it and 3.0 Pro should be
       | out this month if we're lucky.)
       | 
       | Codex with 5.1 high managed to thoughtfully paw through the
       | documentation and source code and - with a little help pulling
       | down parts of the Swift Book - managed to correctly resolve the
       | issue.

       | I remember getting the thread manager right being one of the
       | harder parts of my operating systems course doing an undergrad in
       | computer science; testing threaded programs has always been a
       | challenge. It's a strange circle-of-life moment to realize that
       | what was hard for undergrads also serves as a benchmark for
       | coding agents!
