       | my highlights:
       | 
       | 1. Coding ability: "Claude Opus 4 is our most powerful model yet
       | and the best coding model in the world, leading on SWE-bench
       | (72.5%) and Terminal-bench (43.2%). It delivers sustained
       | performance on long-running tasks that require focused effort and
       | thousands of steps, with the ability to work continuously for
       | several hours--dramatically outperforming all Sonnet models and
       | significantly expanding what AI agents can accomplish." however
       | this is Best of N, with no transparency on size of N and how they
       | decide the best, saying "We then use an internal scoring model to
       | select the best candidate from the remaining attempts." Claude
       | Code is now generally available (we covered in
       | http://latent.space/p/claude-code )
       | 
       | 2. Memory highlight: "Claude Opus 4 also dramatically outperforms
       | all previous models on memory capabilities. When developers build
       | applications that provide Claude local file access, Opus 4
       | becomes skilled at creating and maintaining 'memory files' to
       | store key information. This unlocks better long-term task
       | awareness, coherence, and performance on agent tasks--like Opus 4
       | creating a 'Navigation Guide' while playing Pokemon." Memory
       | Cookbook: https://github.com/anthropics/anthropic-
       | cookbook/blob/main/t...
       | 
       | 3. Raw CoT available: "we've introduced thinking summaries for
       | Claude 4 models that use a smaller model to condense lengthy
       | thought processes. This summarization is only needed about 5% of
       | the time--most thought processes are short enough to display in
       | full. Users requiring raw chains of thought for advanced prompt
       | engineering can contact sales about our new Developer Mode to
       | retain full access."
       | 
       | 4. haha: "We no longer include the third 'planning tool' used by
       | Claude 3.7 Sonnet. " <- psyop?
       | 
       | 5. context caching now has a premium 1hr TTL option: "Developers
       | can now choose between our standard 5-minute time to live (TTL)
       | for prompt caching or opt for an extended 1-hour TTL at an
       | additional cost"

         | 
         | 1 diff at a time might sound great "You can keep tabs on the
         | model each step of the way" and it would be if it did all the
         | edits to a file in one go but instead it does it piecemeal
         | (which is good/makes sense) but the problem is if you are
         | working in something like, a Vue SFC file then it might edit
         | the template and show you a diff, then edit the script and show
         | you a diff, then edit the TS and show you a diff.
         | 
         | By themselves, the diffs don't always make sense and so it's
         | impossible to really give input. It would be as if a junior dev
         | sent you the PR 1 edit at a time and asked you to sign off. Not
         | "1 PR per feature" but literally "1 PR per 5 lines changed",

         | 
         | 1. What type of problem did you try it out with?
         | 
         | 2. Which model did you use (you get points for providing that
         | one!)
         | 
         | 3. Did you consider a better model (compare how Gemini 2.5 Pro
         | compares to Sonnet 3.7 on the Aider leaderboard)?
         | 
         | 4. What were its failings? Buggy code? Correct code but poorly
         | architected? Correct code but used some obscure method to solve
         | it rather than a canonical one?
         | 
         | 5. Was it working on an existing codebase or was this new code?
         | 
         | 6. Did you manage well how many tokens were sent? Did you use a
         | tool that informs you of the number of tokens for each query?
         | 
         | 7. Which tool did you use? It's not just a question of the
         | model, but of how the tool handles the prompts/agents under it.
         | Aider is different from Code which is different from Cursor
         | which is different form Windsurf.
         | 
         | 8. What strategy did you follow? Did you give it the broad spec
         | and ask it to do anything? Did you work bottom up and work
         | incrementally?
         | 
         | I'm not saying LLM coding is the best or can replace a human.
         | But for certain use cases (e.g. simple script, written from

         | 
         | Another Alternative Answer: He actually can't cross the river
         | since he doesn't have a boat and neither the cabbage nor the
         | animals serve as appropriate floatation aids
