These posts are going to be a constant for the next year, because there's no objective way to compare models (past low-level numbers like token generation speed, average reasoning token amount, # of parameters, active experts, etc). They're all quite different in a lot of ways, they're used for many different things by different people, and they're not deterministic. So you're constantly gonna see benchmarks and test…

A pretty simple one would be to have every model try and one shot every ticket your company has and then measure the acceptance rate of each model.

In addition, the harness around these models do a lot of work and changes the outcome significantly. I just had an issue where Claude CLI with Opus 4.7 High could not figure out why my Blazor Server program was inert, buttons didn't do anything etc. After several rounds, I opened the web console and found that it failed to load blazor.js due to 404 on that file. I copied the error message to Claude CLI and after anot…

> However, I'm not convinced this shows GPT 5.5 being that much better than Opus 4.7. It could very well be the harness around it, the system prompts used in the harness and tools available. A model that can more effectively make use of the tools presented to it is going to be better. You're not wrong about the system prompt; these can have quite a pronounced effect, especially when what the agent is bridging to is n…

> A model that can more effectively make use of the tools presented to it is going to be better.

Of course. What I was getting at is that if the harness A doesn't expose certain useful tools that harness B does, it doesn't matter if the model could use those tools.

How on earth did you get that out my post? I was just reporting on a recent experience I had, to make a point that harness+model is a very different thing from just model when it comes to evaluating effectiveness and quality of output.

I'm glad we're seeing a shift towards objectively scored tests. We've been doing this at scale at https://gertlabs.com/rankings , and although the author looks to be running unique one-off samples, it's not surprising to see how well Kimi K2.6 performed. Based on our testing, for coding especially, Kimi is within statistical uncertainty of MiMo V2.5 Pro for top open weights model, and performs much better with tools…

This may be objectively scored, but it is not an indication of anyone's coding capabilities. This test measures which model almost accidentally came up with the best strategy (against other bots). This is not representative of coding. You would need to test 100 or more of such puzzles, widely spread across the puzzle spectrum, to get an idea which model is best at finding strategies involving an English dictionary.

Except that if you tried one-shotting your ticket twenty times at different hours of the day and different days of the week, you would have enough changes to make benchmarks even if you used the same model every time. Much moreso if you fiddled with the thinking or changed the prompt.

Because non-deterministic, because of constant updates and changes, and because the models are throttled according to number of users, releases, et al.

Most people won't roll out their own K2 deployment across rented GPUs, so in that sense it doesn't matter that much, they'll be using a paid service which is just as much of a black box as Claude or ChatGPT. For example, on OpenRouter you can select a provider which state they use a given open model, but you have no idea what actually goes on behind the curtains, which quantization levels they use and so on. That sai…

> but you have no idea what actually goes on behind the curtains, which quantization levels they use and so on. That would take something close to a global conspiracy of every technologist lying continuously to keep the tweaks secret. If necessary, I personally will rent some servers and run a vanilla Kimi K2.6 deployment for people to use at reasonable prices. I don't expect to ever make good on that threat because…

> If one is quantising and another isn't there's a big difference in quality.

Sure. But the problem is you have to do this continuously to have any measure of confidence, which is expensive. For example, a provider could at any point randomly start serving some fraction of the requests to a quantized model. Either due to "routing error", as Anthropic called one of their model degradation events, or trying to improve bottom line.

There's really no good way to detect this on a few-prompt level without overspending significantly, because they're all black boxes.

While I partially agree with you, there IS work being done to make the metrics comparable. Eg:

It just hasn't been widely adopted yet. And it might be in each of their particular interests that it continues to stay so for a while. It's basically like p-hacking.

At the current rate, open sourced models are expected to surpass cloud models within a couple years based on a study I read a couple days ago. Looking back at chatGPT and claude a couple years ago, very small Qwen models are basically equal in coding to what those cloud based models could do then. Also factoring in scaling laws, a 9b going to 18b is roughly a 40% increase, whereas 18b to 35b is 20%, I expect there wi…

The news is not in the way to compare models, it’s that Kimi K2.6 (and I’d add Deepseek v4 Pro) are more or less equivalent to Opus and that’s already pretty big. They are open source and cost waaaay less per token than American models. I’m using them right now on the $20 Ollama cloud plan and I can actually work with them on my side projects without reaching the limits too much. With Claude Pro $20 plan my usage can…

Or maybe it is a pretty good thing for the American economy that you can get AI at cost rather than monopoly pricing.

You know, for the rest of the economy that is not big tech.

My theory is we will end up in a similar spot to hiring people. You can look at a CV (benchmarks) but you won't know for sure until you've worked with them for six months. We as an industry cannot determine if one software engineer is objectively better than another, on practically any dimension, so why do we think we can come to an objective ranking of models?

Yes, the entire field of software engineering ran aground on not being able to test how well people can write software.

But I'm more optimistic about testing programming models. You can run repeated tests, and compare median performance. You can run long tests, like hundreds of hours, while getting more than a few humans to complete half-day tests is a huge project. And you can do ablation testing, where you remove some feature of the environment or tools and see how much it helps/hurts.
