Experimental global target bits‑per‑weight quantization of ServiceNow-AI/Apriel-1.6-15b-Thinker and zai-org/GLM-4.6V-Flash

The method to produce these experimental versions involves using a custom version of llama-imatrix to generate an imatrix including the mean activations, and a custom version of llama-quantize, which computes a per-tensor weighted mean squared quantization error and a bias/projection term (if the imatrix includes activations), to automatically select the lowest error quantization recipe that achieves a global target bits‑per‑weight (bpw).

Applying Hazard and Entropy Analysis to LLMs

Here's an example of a model that behaves perfectly well up to 8k, smoothly increasing its entropy before going into a struggle zone, collapsing, seeing a region of recovery and finally falling down hard at the 16k wall.

Is your model implementation behaving badly like this?

Would you know if it was? 👀

I love getting emails telling me when there's somebody else's active access token in one of my commit SHAs. HF should really only tell you if it is your token, otherwise I could just make a dataset with a bunch of random strings and wait for a valid token.

user,permission,token
nroggendorff,write,hf_...
pepper13,finegrained,hf_...
...,...,...
...

Also, don't comment about how unlikely this is. I've gotten a warning email about a token I 'leaked' at least four times.
In all cases, it has been in the digest hash.

Layer-wise and Pruned versions of Qwen/Qwen3-30B-A3B

* Tesor-wise: eaddario/Qwen3-30B-A3B-GGUF
* Pruned: eaddario/Qwen3-30B-A3B-pruned-GGUF

Even though the Perplexity scores of the pruned version are 3 times higher, the ARC, HellaSwag, MMLU, Truthful QA and WinoGrande scores are holding remarkably well, considering two layers were removed (5 and 39). This seems to support Xin Men et al conclusions in
ShortGPT: Layers in Large Language Models are More Redundant Than You Expect (2403.03853)

Results summary in the model's card and test results in the ./scores directory. Questions/feedback is always welcomed.

The past year I have been trying to get diffusion models to work for language generation, without having to retrain a LLM from scratch. And recently, we finally succeeded:

We introduce "LAD: LoRA-Adapted Denoiser", a method to convert a LLaMA model into a text diffusion model using LoRA finetuning and structured input corruption.

🎯 Try the demo and read the write-up here!
https://ruurdkuiper.github.io/tini-lad/

Unlike autoregressive (word-for-word) models like ChatGPT, diffusion models iteratively refine a noised sequence. However, most current diffusion approaches rely on all-parameter retraining and repeatedly remasking tokens, which is costly and slow during both training and inference!

🧠 With LAD:
- We can finetune an autoregressive model for diffusive generation in just 10 hours on a single GPU.
- Test-time compute is fully adjustable: fewer steps means faster outputs while more steps improve output quality.
- Due to our unique noising schedule, remasking is not always needed during inference. All tokens are attended to in each iteration!

🔍 LAD is built using:
– A frozen LLaMA-8B backbone
– Structured noising: token swaps, duplications, replacements, span shifts
– Modified attention masks for bidirectional decoding

💡 We show that even small, fast-trained models can perform diffusive generation — with competitive benchmark performance, perplexity and more flexible test-time behavior than traditional transformers.

DoLa decoding, which made a conference paper at ICLR '24, has just been merged in Transformers by @joaogante and Yung-Sung Chuang.
This new decoding method is simple yet extremely impressive!

Reminder: Decoder LLMs (the GPT kind of LLM, the most common one) generate their outputs one token at a time: at each step, given a current text, they compute a logit for each token in their vocabulary that should represent the probability of this token coming next.

Then they either pick the highest logit token (greedy decoding) or sample one with a probability defined by the logits (sampling).

The authors of DoLa wanted to improve that simple method.

They knew this established fact that transformer LMs encode low-level info (like base syntax) in early layers and more high-level info like knowledge in the later layers.

💡 This gave them their key idea: During decoding, rather than picking the token with the highest logit, 𝘄𝗵𝘆 𝗻𝗼𝘁 𝗽𝗶𝗰𝗸 𝘁𝗵𝗲 𝘁𝗼𝗸𝗲𝗻 𝘄𝗶𝘁𝗵 𝘁𝗵𝗲 𝗺𝗼𝘀𝘁 𝗶𝗺𝗽𝗿𝗲𝘀𝘀𝗶𝘃𝗲 𝗶𝗻𝗰𝗿𝗲𝗮𝘀𝗲 𝗶𝗻 𝗹𝗼𝗴𝗶𝘁 𝗮𝗰𝗿𝗼𝘀𝘀 𝗹𝗮𝘆𝗲𝗿𝘀?

This gives impressive results:
🚀 𝟱% - 𝟮𝟬% 𝗯𝗮𝘀𝗲 𝗽𝗼𝗶𝗻𝘁𝘀 𝗶𝗻𝗰𝗿𝗲𝗮𝘀𝗲 𝗮𝗰𝗿𝗼𝘀𝘀 𝘁𝗵𝗲 𝗯𝗲𝗻𝗰𝗵𝗺𝗮𝗿𝗸𝘀
🚀 For instance on TruthfulQA / Open-ended, across all model sizes the increase in truthfulness is 14 base points, which is 𝗮𝗿𝗼𝘂𝗻𝗱 𝟰𝟬% 𝗶𝗺𝗽𝗿𝗼𝘃𝗲𝗺𝗲𝗻𝘁 𝗰𝗼𝗺𝗽𝗮𝗿𝗲𝗱 𝘁𝗼 𝘀𝘁𝗮𝗻𝗱𝗮𝗿𝗱 𝗱𝗲𝗰𝗼𝗱𝗶𝗻𝗴!

🤔 Wouldn't decoding take longer because of this added contrasting step? 👉 𝗧𝗵𝗲 𝗿𝘂𝗻𝘁𝗶𝗺𝗲 𝗶𝗻𝗰𝗿𝗲𝗮𝘀𝗲 𝗶𝘀 𝗻𝗲𝗴𝗹𝗶𝗴𝗶𝗯𝗹𝗲, 𝟭 𝘁𝗼 𝟴% 𝗼𝗻𝗹𝘆.

Visualization of GPT-4o breaking away from the quality & speed trade-off curve the LLMs have followed thus far ✂️

Key GPT-4o takeaways
‣ GPT-4o not only offers the highest quality, it also sits amongst the fastest LLMs
‣ For those with speed/latency-sensitive use cases, where previously Claude 3 Haiku or Mixtral 8x7b were leaders, GPT-4o is now a compelling option (though significantly more expensive)
‣ Previously Groq was the only provider to break from the curve using its own LPU chips. OpenAI has done it on Nvidia hardware (one can imagine the potential for GPT-4o on Groq)

👉 How did they do it? Will follow up with more analysis on this but potential approaches include a very large but sparse MoE model (similar to Snowflake's Arctic) and improvements in data quality (likely to have driven much of Llama 3's impressive quality relative to parameter count)

Notes: Throughput represents the median across providers over the last 14 days of measurements (8x per day)
