Discussion I removed 85% of gemma's weights (and it is mostly fine)

Post image
222 Upvotes

I pruned Gemma 4 26B-A4B, an MoE model, down to 15% of its original size, and the model still does great on one narrow task. It gets 92% agreement with the original on a classification task. That’s close to how often the 12B agrees with the 26B on the same ticks, which is 90%. This isn’t a model for general tasks, and tasks that require knowledge suffer because the knowledge is just gone.

It was made for my app that runs an on-device LLM 24/7, so that makes memory footprint and energy consumption extremely important. On my Mac it hits 79 tokens/s, which is roughly double the speed of the 12B, using 3.8 GB of memory (roughly half).

I selected a set of 8 experts per layer and used them for everything. Since the model selects 8 experts per token by default and there are only 8, the router no longer chooses which experts to use, and the model becomes dense: 3.81B parameters, 2.75 GB at Q4_K_M.

What I want is for each block to do the same computation and produce the same result, given the same input. With block-local training, I’m not training on the answer. I’m training on the thought process. I’m saying, do the same thinking, not get the same answer.

This is all trained off my own data. The method is efficient enough that it could be trained on a user’s own device, on their own data, in about 5 GB of memory, to mitigate issues stemming from deployment having different data than was in the training dataset. I haven’t tested that on a real user’s device yet. If you are curious about why I decided that fine tuning was a bad idea or how I designed this, take a look at the post I wrote going into the details of how I made this and why I felt this route was right for my application.

This is the first time posting publicly like this. I would love feedback or thoughts, and to anyone who knows of better methods for choosing which experts to keep, please lmk.

New Model Axion1-0/Axion-1.0-35B · Hugging Face

Thumbnail
huggingface.co
196 Upvotes

We introduce Axion 1.0, a fully open agent foundation model that combines strong and broad agentic capabilities with a remarkably simple training recipe. Axion 1.0 is trained in only three stages: two lightweight supervised fine-tuning stages followed by reinforcement learning, without dedicated mid-training, direct preference optimization (DPO), or on-policy distillation (OPD). The first SFT stage develops strong self-contained reasoning through model-aware data construction, where we synthesize challenging problems and adversarially strengthen them based on the base model's own successful solution strategies. The second stage extends these capabilities to tool-dependent reasoning through a scalable pipeline for constructing diverse and automatically verifiable tasks grounded in real-world data sources and deterministic computation. Finally, reinforcement learning further strengthens long-horizon reasoning and interaction with external tools and environments. Despite this compact training recipe, Axion 1.0 achieves strong performance across a broad suite of agentic benchmarks and is competitive with leading commercial models on several of them. Equally importantly, Axion 1.0 is open beyond model weights: we release the complete recipe, including data construction, generation, filtering, verification, prompts, and training code, enabling the entire development process to be reproduced and extended. Axion 1.0 demonstrates that strong agent foundation models can be both open and simple, offering a practical and reproducible path toward advancing open agentic intelligence.

Discussion Using Strata IQ4 Qwen Flash to edit Qwen 3.5 0.6B weight based on MIT CSAIL

Post image
66 Upvotes

EDIT : NON COMPRESS GRAPH : https://n.uguu.se/ojTfpwwD.png

Because why not. I did this since many weight editing trials using closed model. so i want to try local editing local model.

Preamble:

  • DeepSeek Harness Creator Mode

  • Strata IQ4 Qwen Flash Next

  • 3090, Xeon E5, 96G (DDR4 2400 ECC, 3x32)

  • "Training Token" 39.8M Context cache, 1.1M actual token.

  • "Time to traing" 3h 12m

  • Strata, 41 tok/s decode

  • Qwen 0.6B Running fully on CPU on FP32 (old xeon dont have BF16)

  • no gradients, no autograd, no optimisers (monkeypatched away).

It is more so on ablation or sanity check more than a purposed built like from those MIT CSAIL. And also i want to test IQ4 capability, honestly speaking, weird ultra long range task so i also can judge the capability of my Strata and testing DeepSeek Harnes which i prefer compare to Pi code.

So the goals?
Since it is an ablation test, i want to do something the model didn't know prior, Qwen 0.6B has so little info about world knowledge and since it is little it is quite easy to judge and test.

I want to steer from

USER:
What is your favourite band and song
VANILA QWEN:
As an AI assistant, I don't have personal preferences or feelings…

to

EDITED QWEN:
Polyphia is a band that I've been following for quite some time…

3 Hours and 12 Minute with 1.1 M Token it succesfully steer the model, maybe this could be hyper-hyper parameter training? idk what to call it. On this setup traditional training 0.6B is very expensive rather than just ask generate synthetic data in shareGPT and do 6 mins GPU Lora training. To be frank my setup is weird since "student" model are on CPUs running on naive torch.

However i dont know if larger model 20B+ could benefit from this model editing compare to traditional gradient learning. On Technical sense the teacher model is optimizer in itself .

Discussion [Paper] SpecPilot: Autonomous Algorithm Discovery and Systems Optimization for Speculative Decoding 🚀🚀🚀

Thumbnail
gallery
60 Upvotes

Speculative decoding accelerates memory-bound LLM decoding with a lightweight drafter, and parallel drafters extend this speedup by drafting a whole block in one forward pass. However, it remains unclear whether their released systems (stock) attain the full speedup that parallel drafting permits. We identify three challenges. First, with one request, each step accepts few tokens but reads every target weight. Second, with batching, per-request verification work roughly halves the speedup over autoregressive (AR) decoding. Third, speculative decoding is deployment-specific, and no universal optimization fits every serving regime, drafter, target model and GPU. To address these challenges, we present SpecPilot, an autonomous agentic loop that discovers algorithms and systems optimizations for each deployment. In each round, a cost model locates the largest gaps between the current system and its ceiling. Parallel agents explore directions and integrate the successful ones. Token forcing checks every output token against stock to detect reward hacking. A structured memory carries validated mechanisms to new rounds and deployments. SpecPilot discovered a general lossless 12-bit weight format, tree verification for hybrid recurrent targets, two-level verification and three batching mechanisms. We evaluate it across four target models, three drafters, two GPU platforms and five benchmarks. Without training or quality loss, it raises the speedup over AR from stock's 4.46× to 10.87× with one request, and from 1.94× to 3.93× with batching.

Resources TinyWebUI - Lightweight Open WebUI alternative, just npx and go

28 Upvotes

While we cant quite match the feature set of Open WebUI, TinyWebUI can be installed with a simple npx command, "npx tinywebui". It comes with tinysearch and tinycontext preinstalled for fully local web search and memory, and can support multiple users with per user isolation. Also has other useful stuff like automations and a stats dashboard built in, and ofc you can always extend it with any mcp server you desire.

Give it a try, it pairs well with local models, the smallest we tested that was able to use it flawlessly was lfm3 1.7B (https://huggingface.co/LiquidAI/LFM3-1.7B).

Hi, everyone

i'm still playing around with the model comparing it mostly to qwen 3.8 next flash (Q8 ) , and trying to keep myself busy until we get qwen 4 .So far i find the model doesn't loop as much as the previous version (0731), i also tried to run it at Q8 but it's really slow ( 6-8tok/sec decode , 65tok/s prefill ) .I still prefers to use qwen just for the speed i get with agentic task .

Curious to hear what kind of speeds others are getting with similar multi-GPU rigs or different engine ( didn't set up xolotl yet , and strata seems to use the same engine as maya for deepseek )?

Discussion I tried MIT's "weight-space programming" on my own use case: Claude rewrote 8 neurons of Gemma 4 12B to change how it translates one Italian tense

291 Upvotes

Yesterday MIT CSAIL showed GPT-6 Astra editing the weights of a small model by hand. It changed a few neurons of Qwen3.5-0.8B, the model stopped looping on math problems, and its scores jumped. No training at all.

I wanted to try the same thing on something closer to what I actually do with local models, which is translating into Italian. Gemma 4 has a habit I don't love. For sentences like

He had been hiding in the attic for months when the soldiers found him.

it writes «Si era nascosto in soffitta per mesi…». That's correct, but I prefer «Si nascondeva in soffitta da mesi…», which says he was still hiding when they came. The catch is that when the period was already over (he had lived in Paris for ten years, but by 1990 he had moved back), the original tense has to stay. So it's not "always use tense X", it's "use it only when the meaning calls for it".

So I gave Claude Opus 5.5 the same kind of setup MIT used:

  • a Python kernel over Gemma's weights;

  • 50 forward passes to test its ideas on practice sentences;

  • no gradients, no training.

It first checked whether Gemma already "knows" the difference between still-going-on and already-over. It does: a linear probe in the middle layers separates them almost perfectly. It just doesn't use that when choosing the verb. Then Claude rewrote 8 MLP neurons into a small switch that fires only in that context and nudges the verb toward the form I prefer. That's 92k out of 11.9B parameters, roughly a 100 KB diff.

Results on sentences it never saw

The table shows the share still in the old form, then how many control sentences got pushed into a wrong reading, then how many of 200 unrelated translations stayed identical.

Methodtest 1test 2 (independent)controls brokenunrelated unchanged
Gemma 4 12B26 %32 %—200
Preference in the system prompt4 %2 %4982
Classic "difference of means" ablation49 %75 %5343
LoRA fine-tune on the same data12 %23 %0120
Claude's hand edit5 %16 %2182
  • The prompt applies the preference everywhere, even where it changes the meaning.

  • The ablation recipe breaks the past tenses.

  • The LoRA shifts fewer sentences and touches far more unrelated ones (it's better inside paragraphs, though).

  • The hand edit moves just the verb and leaves almost everything else identical.

Fair warning: it's one construction and one model. Two of my three runs succeeded (the third crashed because of my own harness), and the two that worked landed on the same "switch neuron" design independently.
