At least this one gave credit to the upstream projects which it used as a reference.
The llama.cpp project is also getting a wave of vibecoded PRs that are very clearly being produced by pointing claude at the repo and the original paper and having it produce something.
Almost none of these attempts contain information that really matters, like actual benchmark tests with differen KV quantization levels (not just perplexity or KLD).
Going from paper to implementation from scratch in half an hour or so is great.
It's not inherently bad in the same way that a first draft of a novel is not inherently bad.
But if someone asked me to read their novel and it was a first draft that they themselves had clearly not bothered reading or editing, I'd tell them to fuck off.
These are more like sending someone who didn't ask you a question a LMGTFY link they didn't ask for and expecting them to read all the results. Just a complete lack of awareness and respect for the maintainers
Software is valuable if it has been tested and exercised properly by other people. I don't care if you vide coded it provided you then put the real work in to verify that it actually works correctly - and then include the proof that you've done that when you start widely sharing it with the world.
Right now it's impossible to tell which of these projects implementing the paper are worth spending time with.
This repo isn’t showing that at all. Scroll to the bottom of the README and you’ll see the other project it was based on.
My problem with this specific type of vibe coded project is that it’s initially presented as something more novel or polished in order to get more upvotes, karma, likes, or pad a resume. Then you read it and discover they just pointed Claude at some other projects and told it to produce something similar, then posted it as their own work.
Where’s the value added if the person just tells Claude to do it and then submits a PR?
The maintainers may as well vibe code it themselves if that’s all the work the would-be contributor is going to put into it.
we live in a wholly unoptimized world because the available resources have been so high, while the benefits of optimizing have been so low. that has flipped now and there are tons of low hanging fruit to optimize.
I agree that benchmarks would be great, but thats only relevant to this one topic, not the overall agentic coded pull request concept itself
A PR without evidence it works and expectations for the benefits using the new feature would bring is kind of worthless.
If it works in one case that doesn't mean it works consistently or well in the general case
I've made lots of things with Claude Code that just work... until I do things in a slightly different order and the whole thing explodes
Llama.cpp already has KV compression and one of the turbo quant PRs will get merged at some point.
If you don’t care about the fancy 3 bit, the q8 KV compression is good enough! Don’t bother with q4
./build/bin/llama-server -m model.gguf \ --cache-type-k q8_0 \ --cache-type-v q8_0 \ -c 65536
Etc
Ofcourse large corps will have fancy proprietary models, but for every day queries and tasks, local feels like a huge, and just slightly out of reach.
Am i missing something fundamental?

TurboQuant KV compression: We ported the V3 Lloyd-Max codebooks from the TurboQuant paper (Zandieh et al., ICLR 2026) into native C++ and fused dequantization into Metal shaders. This achieves a measured 4.3× KV cache compression at runtime, completely eliminating Python overhead.
SSD Expert Streaming: To fit a 122B parameter model (e.g., Qwen3.5-122B MoE) without triggering macOS VM swapping or Watchdog kernel kills, the full ~60 GB weight file remains on NVMe. Only the top-k active expert pages are streamed to the GPU per forward pass at ~9 GB/s. As a result, inference runs with only 2,694 MB of active GPU VRAM on the M5 Pro 64GB, while the OS page cache automatically handles hot-expert reuse.
By combining these two approaches, we can comfortably run massive models in memory-constrained environments on Apple Silicon.
Also tested QWEN 4B on IPHONE 13 Pro.

One thing I've turned up in smaller models and I'm sort of winding my way toward verifying in larger ones is that if you train the MoE model from scratch with this kind of knockout / subset of experts baked in, then you get significantly better loss outcomes. In small models, it's actually better than training an MOE without conditioning on a reduced set of experts per pass.
Anyway, pretty cool. There's some Pareto-optimal curve based on memory bandwidth, amount of GPU / unified RAM and inference compute times for streaming stuff in.
