Your "research" is a vibe-coded mess that subtly cheats eval cleverly multiple times to inflate your results. The HellaSwag dataset is a dataset with 4 options for each question, with 3 being wrong and 1 being right: https://huggingface.co/datasets/Rowan/hellaswag. Your vibe-coded eval has cheated this to collapse it into a binary selection on row 46 in https://github.com/Anima-Core/an1-core/blob/main/experiments..., making the problem baseline 50% on random choice instead of 25%, making the problem much easier. HellaSwag is specifically constructed with adversarial examples that could be plausible. By not including them, the eval is much easier. --- Then, in extract_fields_from_model, you have another cheating going on. The extraction logic (h[:, -1, :]) fails to account for padding in batches, likely extracting EOS/Pad tokens instead of

the intended content tokens. This suggests the probe is relying on global sentence summaries (standard embeddings in causal structures) rather than the novel 'meaning fields' claimed in the paper. --- I dont have time to look at more of this and I just looked at how the eval is made, but please dont waste peoples times when you dont even know what you are evaluating.
In Post-transformer inference: 224× compression of Llama-70B with improved accuracy
I might be overly pessimistic, but this looks like a case of a person believing LLM hallucinations and making it write a paper. I asked both Claude Code|Opus 4.5 and Codex|GPT 5.1 Codex Max (funny to ask LLMs, I know) to check the an1-core repo. I don't think they'd hallucinate on something like this (the code is quite small), but I do not claim expertise. In short, both of them are saying that: - The repo always runs the full teacher model to extract activations and uses them - see https://github.com/Anima-Core/an1-core/blob/main/an1_core/fi... - There are weird stub files, e.g. the Hellaswag repro doesn't actually have the code to reproduce https://github.com/Anima-Core/an1-core/blob/main/experiments... "For full HellaSwag reproduction, see the paper" (why include the file at all then?) - The actual "AN1 head" is just linear probing (fr

eeze a pretrained model, train a classifier on its features). The full flow (as reported by CC) is "Text → [Full Transformer] → activations → [Tiny Head] → prediction" Basically, there's no code to train a real "student" model that would run without the teacher. === The repo/paper say that there's a mythical "commercial version" that has all the goodies: (repo) > This reference implementation (an1-core) does not include the FPU, AN4, or other proprietary optimization components covered by these patents. It provides only the core scientific demonstration of the meaning fields phenomenon. (paper) > Production deployment: Optimized implementations (AN1-Turbo) with learned layer selection, adaptive loss scheduling, and CUDA-accelerated inference available under commercial license. But right now we only have the code in the repo. === In the paper they show that the student model (30M params) gets ~82% on SST-2 (labels-only). But what what they don't show is that DistilBERT (>5 year old model) already achieves 91% on the same dataset despite only having 66M params. Another weird tidbit from the paper - in the section where they show the economic impact, they claim that LLaMA 70B runs at 2 tok/s at batch size=1 on an H200. In reality that number is at least a magnitude bigger even without quantization, like 20-40 tok/s. With quantization it can easily be above 100 tok/s.
In Post-transformer inference: 224× compression of Llama-70B with improved accuracy
I’m actually building the system-level approach this memo hints at. I’m not from a lab or an academic group, but I’ve been working on a post-transformer inference method where you extract a low-rank “meaning field” from a frozen Llama-70B layer and train a small student model to generate those fields directly. The idea is similar to what this memo describes, but with an empirical implementation. I just open-sourced the reference version here: GitHub: https://github.com/Anima-Core/an1-core Paper + DOI: https://zenodo.org/records/17873275 It isn’t about bigger models. It’s about reorganizing the system around meaning and structure, then treating the transformer as a teacher rather than the final destination. I’d genuinely appreciate critique or replication attempts from people here. HN tends to give the most honest feedback.
In The Solution Will Come from the Field
I’ve been working independently on a method that replaces full-transformer inference with a low-rank “meaning field” extracted from internal activations. The core result: a frozen Llama-3.3-70B can be distilled into a 256-dimensional field representation, giving 224× compression and slightly higher accuracy on several benchmarks. A small student model then learns to directly generate these fields from text, removing the transformer from the inference path. The Zenodo link contains the full paper, statistical results, and methodology. A reference implementation (non-optimized) is here: https://github.com/Anima-Core/an1-core Production variants (AN1-Turbo, FPU work, etc.) are not included. I’m an outsider to academia so I’m posting this openly to get technical feedback, replication attempts, and critique from people who understand this sp
