Is it wherever the tokens are, or is it the N first tokens they've seen before? Ie if my prompt is 99% the same, except for the first token, will it be cached?
The prefix has to be stable. If you are 99% the same but the first token is different it won't cache at all. You end up having to design your prompts to accommodate this.
a simple alternative approach is to introduce hysteresis by having both a high and low context limit. if you hit the higher limit, trim to the lower. this batches together the cache misses.
if users are able to edit, remove or re-generate earlier messages, you can further improve on that by keeping track of cache prefixes and their TTLs, so rather than blindly trimming to the lower limit, you instead trim to the longest active cache prefix. only if there are none, do you trim to the lower limit.

One of the main issues I had with Claude Code (maybe it‘s the harness?) was that the agent tends to NOT read enough relevant code before it makes a change. This leads to unnecessary helper functions instead of using existing helper functions and so on. Not sure if it is an issue with the models or with the system prompts and so on or both.
Helpfer functions exploded over the last releases, id say? Very often I state: "combine this into one function" another thing I saw in the last days starting: Claude now draws always an ASCII art instead of a graphical image, and the ASCII art is completely useless, when something is explained

I think its a valid complaint. Who wants to constantly spend overhead on maintaining what's current without clear definitions and adding uncertainty to your tooling. It's a total PITA.
Then don't? I don't think it's a valid complaint at _all_. It's totally fine to just pick one tool (chatGPT, Claude, Gemini) and just use whatever the best default they allow you to use. You'll get 90% of the benefits and not have to think at all. AI is new and developing at breakneck pace. You can't complain that you want to get bleeding edge without having to do research or change workflows. That's already unrealis…
Re: Claude Haiku 4.5
#275What is the use case for these tiny models? Is it speed? Is it to move on device somewhere? Or is it to provide some relief in pricing somewhere in the API? It seems like most use is through the Claude subscription and therefore the use case here is basically non-existent.
The rules themselves are a bit more complex and require a smarter model, but the arbitration should be fairly fast. GPT-5 is cheap and high quality but even gpt-5-mini takes about 20-40 seconds to handle a scene. Sonnet can hit 8 seconds with RAG but it's too expensive for freemium.
Grok Turbo and Haiku 3 were fast but often misses the mark. I'm hoping Haiku 4.5 can go below 4 seconds and have decent accuracy. 20 seconds is too long, and hurts debugging as well.
Re: Claude Haiku 4.5
#276Worked with it a bit last night! Seems quick. I did run into the same problem I have with Gemini often where the response says something like, "I need to do x" or "I did x" and then nothing actually happens. Agent seems to think it actually does finish the task but it stops part way. But I'm sure they will sort that out, as I dont have that issue with other anthropic models.
I’ve been wondering how Cursor et al solved this problem (having the LLM explain what it will do before doing it is vitally important IMO), but maybe it’s just not a problem with the big models.
Your experience seems to support that smaller models are just generally worse about tool calling (were you using Gemini Flash?) when asked to reason first.

I don’t mean this with snark, but with age. It’s actually totally cool to not upgrade and then you have stability in your tooling. I bet there is some hella good art being made with Photoshop 6.0 from the 90s right now. The upgrade path is like the technical hedonistic treadmill. You don’t have to upgrade.
Almost all my tooling is years (or decades) old and stable. But the code assistant LLM scene effectively didn't exist in any meaningful way until this year, and it changes almost daily. There is no stability in the tooling, and you're missing out if you don't switch to newer models at least every few weeks right now. Codex (OpenAI/ChatGPT CLI) didn't even exist a month ago, and it's a contender for the best option. C…
Re: Claude Haiku 4.5
#278Very preliminary testing is very promising, seems far more precise in code changes over GPT-5 models in not ingesting irrelevant to the task at hand code sections for changes which tends to make GPT-5 as a coding assistant take longer than sometimes expected. With that being the case, it is possible that in actual day-to-day use, Haiku 4.5 may be less expensive than the raw cost breakdown may appear initially, though…
One of the main issues I had with Claude Code (maybe it‘s the harness?) was that the agent tends to NOT read enough relevant code before it makes a change. This leads to unnecessary helper functions instead of using existing helper functions and so on. Not sure if it is an issue with the models or with the system prompts and so on or both.
GPT 5 (at least with cline) reads whatever you give it, then laser targets the required changes.
With High, as long as I actually provided enough relevant context it usually one shots the solution and sometimes even finds things I left out.
The only downside for me is it's extremely slow, but I still use it on anything nuanced.

> Everyone believes their task requires no less than Opus it seems after all. I have solid evidence that it does. I have been using Opus daily, locally and on Terragonlabs for Rust work since June (on Max plan) and now, since a bit more than a week, being forced to use Sonnet 4.5 most of the time. Because of [1] (see also my comments there, same handle as HN). Letting Sonnet do tasks on Terry, unsupervised is kinda u…
This is an interesting perspective to me. For my work, Sonnet 4.5 is almost always better than Opus 4.1. Opus might still have a slight edge when it comes to complex edge-cases or niche topics, but that's about it. And this is coming from someone who used to use Opus exclusively over Sonnet 4, as I found it was better in pretty much all ways other than speed. I no longer believe that with Sonnet 4.5. So, it is intere…
I.e. I can tell from the generated code on this vs. other 'topics' that the model has not seen much or any "prior art".
Re: Claude Haiku 4.5
#280I just don't find the benchmarks on the site here at all believable. codex for me with gpt-5 is so much better then claude any model version. I mean maybe it's because they compare to gpt-5-codex model but they don't mention is that high, medium, low, etc... so it's just misleading probably... but i must reiterate zero loyalty to any AI vendor. 100% what solves the problem more consistently and of a higher quality an…
Out of curiosity, what kind of work do you use them for? I did a comparison of a few different models for setting up a home server with k3s and a few web apps in nextjs. Claude was my favorite for both tasks, but mainly because it seemed to take my feedback a lot better than others.
