A fixed-price testing service that identifies the cheapest local model configuration that still passes a buyer's real workloads.

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.
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.
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.

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...
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.
