What 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.

Higher token throughput is great for use cases where the smaller, faster model still generates acceptable results. Final response time improvements feel so good in any sort of user interface.

I am a professional developer so I don't care about the costs. I would be willing to pay more for 4.5 Haiku vs 4.5 Sonnet because the speed is so valuable. I spend way to much time waiting for the cutting edge models to return a response. 73% on SWE Bench is plenty good enough for me.

How do you review code when the LLM can produce so much so fast?

with an LLM

Those numbers don’t mean anything without average token usage stats.

Exactly, token per dollar rates are useful, but without knowing the typical input output token distribution for each model on this specific task, the numbers alone don’t give a full picture of cost.

That’s how they lie to us. Companies can advertise cheap prices to lure you in but they know very well how many tokens you’re going to use on average so they will still make more profit than ever, especially if you’re using any kind of reasoning model which is just like a blank check for them to print money.

I vastly prefer the manual caching. There are several aspects of automatic caching that are suboptimal, with only moderately less developer burden. I don’t use Anthropic much but I wish the others had manual cache options

What's sub-optimal about the OpenAI approach, where you get 90% discount on tokens that you've previously sent within X minutes?

because you can have multiple breakpoints with Anthropic's approach, whereas with OpenAI, you only have breakpoints for what was sent.

for example if a user sends a large number of tokens, like a file, and a question, and then they change the question.

I've benchmarked it on the Extended NYT Connections ( https://github.com/lechmazur/nyt-connections/ ). It scores 20.0 compared to 10.0 for Haiku 3.5, 19.2 for Sonnet 3.7, 26.6 for Sonnet 4.0, and 46.1 for Sonnet 4.5.

This is such a cool benchmark idea, love it

Do you have any other cool benchmarks you like? Especially any related to tools

Ain't nobody got time to pick models and compare features. It's annoying enough having to switch from one LLM ecosystem to another all the time due to vague usage restrictions. I'm paying $20/mo to Anthropic for Claude Code, to OpenAI for Codex, and previously to Cursor for...I don't even know what. I know Cursor lets you select a few different models under the covers, but I have no idea how they differ, nor do I car…

> Ain't nobody got time to pick models and compare features

Then don't? Seems like a weird thing to complain about.

I just use whatever's available. I like Claude for coding and ChatGPT for generic tasks, that's the extent of my "pick and compare"

I thought OpenAI would still handle case? Their cache would work up to the end of the file and you would then pay for uncached tokens for the user's question. Have I misunderstood how their caching works?

It's not about storing data on disk, it's about keeping data resident in memory.

Deepseek pioneered automatic prefix caching and caches on SSD. SSD reads are so fast compared to LLM inference that I can't think of a reason to waste ram on it.

It’s not instantly fast though. Context is probably ~20gb of VRAM at max context size. That’s gonna take some time to get from SSD no matter what.

TtFT will get slower if you export kv cache to SSD.

We’re in the stage where the 8080,8085, Z80, 6502 and 6809 CPUs are all in the market, and the relevant buses are S100, with other buses not yet standardized.

You either live with what you’re using or you change around and fiddle with things constantly.
