The Problem

Teams deploying local LLMs cannot reliably infer production quality from model size or precision labels. A quantized model may perform well on short prompts but fail unpredictably during coding, tool use, multimodal work, or long-running agent tasks, while hardware compatibility can introduce errors or erase expected speed gains.

Potential Solution

Provide a managed benchmark service that tests a buyer's prompts, evaluation cases, model candidates, quantization formats, and target hardware. The deliverable is a reproducible comparison of quality, latency, memory use, throughput, and failure patterns, followed by a recommended deployment configuration. Start as a hands-on laboratory service and productize the repeated test harness and hardware profiles over time.

Why Now?

Long-horizon agent workflows make small model degradations compound into visible failures. At the same time, rapidly changing model formats and hardware-specific precision support make configuration decisions harder to generalize from public benchmarks.

Let’s create a new benchmark that actually tells us people here just how good a model is

We already have a thousand ways to measure model quality, and honestly it just makes things harder. There are already too many benchmarks, so I'm not sure we need another one. What seems to be missing in local AI benchmarking is automatic tuning. Nobody is really focusing on finding the best runtime parameters for a given hardware setup, architecture, and quantization. That's a much more practical problem for end users. That's pretty much the gap I'm trying to fill rn

At what context depth does KV quantization start to hurt? Experimental F16 vs Q8/Q4 sequence-parity PoC

I’m coming to this problem from a somewhat different area: computer vision / YOLO deployment. While comparing FP32 reference models with INT8 deployed models, I became interested in a simple debugging question: **An aggregate quality metric may look acceptable, but where does deployed behavior actually begin to diverge from the reference?** This grew out of a reference-vs-deployed parity workflow I previously discussed in the YOLO community, where the paired-output diagnostic direction received positive feedback [（github.com/.../25250](github.com/.../25250). Recently I’ve been following the KV-cache quantization discussions here as well. There have been some very useful KLD sweeps comparing 23 different KV precision combinations at 50K context ([Qwen3.6-27B - Effect of KV quantization on KLD - Q8, Q6, Q5 (bartowski)](reddit.com/.../A2f6a3YskP)). Those experiments answer an important question: >How much does this KV configuration differ overall? What I wanted to add is another axis: At what context depth does that difference begin to become persistent? In other words: aggregate KLD + context depth ↓ divergence trajectory There is also a recent discussion around on-write / on-the-fly KV quantization and whether repeated use of quantized KV state can contribute to long-context degradation ([Qwen3.8-27b q8 KV cache does seem to actually hurt model performance](reddit.com/.../xkUUmOfkD2)). I don’t want to assume that mechanism is universally correct. What I’d like to test is more basic: Does reference-vs-quantized divergence change systematically with context depth, and if so, where does persistent divergence begin? **How the PoC works** The first version del...

Welcome to AGI part 1 - Fable 5.1, Muse Spark beats Sol, 3 new world models blow our minds

ThursdAI - The top AI news from the past week

Yeah, you can get pretty crazy quantization, even if you just use the regular onslaught mix plants at, at two bits. So the thing is that quantization, when you go to larger models, you can still get something very useful, even if you go down to, two bit and stuff. However, there are many, it does open up many edge cases for other uses. So since I work at one bit models at Prism ML, it did look pretty good on the benchmarks, but there are other things like it might just drop multilingual support and it might drop this. So if that works for your use case, then yeah, go for it, test it. But keep in mind that there are going to be losses elsewhere and it might be quite dramatic.

The Entity That Holds Your Capacity

The Guardrail

And decide, deliberately, whether the tray store sits inside or outside the boundary you drew, then write that decision down, because the next person to plug an agent framework into that stack will otherwise re-decide it by accident. Quantization belongs in the approved model record too. If you are running large models on 128 gigabyte class hardware you are running quantized weights. And by the quantizer's own published measurement, a 1-bit quantization retains about 71% of top 1% accuracy and a 3-bit retains about 82. Those are the vendor's own numbers. And public benchmarks are gamed within about 90 days of release. No benchmark is auditable in a way that survives the next training cycle, which is why the obligation is to document your own evaluation methodology against your own workload.

Keeping up with model launches

Ehhh, there's way too many wrenches to throw at a general tierlist like that though. Extra RAM makes some MoEs especially appetizing, outside of their expected full VRAM budget. Plus there's a huge divide on quant size and kvcache quantizing that can throw each model up or down two full tiers on your list. Agentic? Huge speed and kvcache now a necessity, move the model up a tier. Writing? Throw out Qwen entirely, it can do reports but anything remotely resembling creative is atrocious to the point where if you told me the dataset was poisoned I'd believe you. It's honestly exhausting interacting with people about quantizing, too... Sure, in a perfect world everyone has infinite VRAM and nobody quantizes anything, but this is not a perfect world. Nor are we using perfect models. Rent's cheaper than VRAM and that's saying something. Sorry for the digression. I've seen some attempts at megathreads for your topic but they don't get much traction. Even the use cases and rigor of testing is difficult, with busted quants and malformed jinja releases all over. Very easy to burn a dozen hours and not be sure you got a fair shot.
