Signal, extracted.
Top Dog Studios LLC is a New York quantitative firm with two lines of work: Palladium Data, high-density pre-training corpora for language models, and systematic market-making on regulated U.S. event-contract venues. One discipline underneath both — measure precisely, discard noise, act on what remains.
Palladium Data — train smarter, not bigger.
Physics-filtered pre-training data that delivers 17% lower loss than standard web corpora at identical compute budget. Information theory separates signal from noise — so your model trains faster on less data.
§1 The Problem
Most LLM training corpora are built by scraping the internet and applying heuristic filters. The result: billions of tokens of SEO spam, boilerplate, duplicated content, and low-information text that your model must process before it learns anything useful.
Palladium Data takes a different approach. We treat data filtration as a physics problem — using information theory to quantify the information density of every document. The result is a corpus where every token carries measurably more signal.
§2 Results
We trained Qwen 2.5 (1.5B) on three datasets under identical conditions: same base model, same hyperparameters, same token budget (5M tokens), same hardware (NVIDIA A5000). Only the training data changes.

2.1 Training Loss
| Dataset | Final Loss | Time (hrs) | Tokens/sec |
|---|---|---|---|
| Palladium-1M | 2.206 | 0.62 | 2,244 |
| FineWeb-Edu | 2.306 | 0.64 | 2,184 |
| FineWeb (baseline) | 2.654 | 0.64 | 2,173 |
Table 1. Training results on Qwen 2.5 (1.5B) with 5M token budget. Palladium achieves 17% lower final loss than FineWeb and 4.3% lower than FineWeb-Edu under identical compute constraints.
Figure 1. Training loss over 77 steps. Palladium (gold) maintains consistently lower loss throughout training, with visibly smoother convergence than both baselines. The separation is immediate and sustained.
2.2 Downstream Evaluation
We evaluated all models on five standard benchmarks. At the 5M token scale, downstream performance remains stable across all datasets — no degradation from the curated corpus. This is expected: continued pre-training at this scale primarily affects loss and perplexity, while downstream benchmark shifts require orders of magnitude more data.
| Task | Base | FineWeb | FineWeb-Edu | Palladium |
|---|---|---|---|---|
| MMLU | 59.69 | 59.75 | 59.72 | 59.68 |
| ARC-Challenge | 41.38 | 40.87 | 41.47 | 41.13 |
| HellaSwag | 50.22 | 50.26 | 50.39 | 50.29 |
| Winogrande | 63.22 | 63.38 | 62.83 | 64.09 |
| PIQA | 75.52 | 75.63 | 75.46 | 75.57 |

§3 Methodology
Traditional data filtering relies on LLM-based "quality classifiers" — asking one neural network to judge text for another. This is circular, computationally expensive, and blind to information density. Palladium takes a first-principles approach grounded in information theory.
Entropy Measurement
We compress every document using ZSTD and measure the ratio of raw size to compressed size — a direct proxy for Shannon entropy. Highly compressible text indicates repetition, boilerplate, or formulaic content. We discard it.
Sophistication Scoring
Entropy alone is insufficient — random noise has high entropy but zero informational value. We cross-reference with linguistic sophistication: vocabulary diversity, sentence complexity, and information yield per token. Documents must clear both thresholds.
The Goldilocks Filter
The intersection of high entropy and high sophistication defines the "Goldilocks Zone" — roughly the top 10% of the open web by information density. Everything outside this zone is noise. The survivors constitute the Palladium corpus.
For a document d, the information density ρ(d) is defined as the ratio |d|raw / |d|compressed. Documents with ρ > τ (where τ is empirically determined) contain sufficient novelty per token to justify inclusion in the training corpus. The Palladium corpus has mean ρ = 2.32.
§4 Use Cases
Palladium is designed for teams where compute efficiency is a binding constraint.
Small Model Teams
Training 1B–7B parameter models where every token matters. Match larger-dataset performance with a fraction of the data.
Domain Specialization
Building models for finance, legal, science, or engineering. Start from a high-quality general foundation, not raw web crawl.
RAG & Knowledge Bases
Need a clean, dense knowledge base without boilerplate? Palladium documents are pre-filtered for information density.
Systematic market-making on regulated event venues.
Top Dog Studios operates automated two-sided quoting systems on regulated U.S. event-contract exchanges. The firm holds an institutional account on a CFTC-regulated designated contract market and is engaged with additional regulated venues, running cross-venue price research and fee-aware, risk-netted execution.
The approach mirrors the data business: measure the microstructure precisely, price only what the measurements support, and let discipline — not conviction — set the size.
