| 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"

| Some downsides to the JetBrains plugin I've found after playing
| with it some more:
|
| - No alert/notification when it's waiting for the user. The
| console rings a bell but there is no indication it's waiting
| for you to approve a tool/edit
|
| - Diff popup for every file edited. This means you have to
| babysit it even closer.
|
| 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",
| it's useless.
|
| As of right now I'm going back to the CLI, this is a downgrade.
| I review diffs in IDEA before committing anyway and can use the
| diff tools without issue so this plugin only takes away
| features for me.

|
| 4. What were its failings? Buggy code? Correct code but poorly

|
| 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

|
| 7. Which tool did you use? It's not just a question of the

| 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

|
