Interpreting Across Time

How do properties of models emerge and evolve over the course of training?

[IMG: Eliciting Latent Knowledge]

Eliciting Latent Knowledge

As models get smarter, humans won't always be able to independently check if a model's claims are true or false. We aim to circumvent this issue by directly eliciting latent knowledge (ELK) inside the model’s activations.

Quantifying the Effect of Test Set Contamination on Generative Evaluations

16 February 2026

arXiv

As frontier AI systems are pretrained on web-scale data, test set contamination has become a critical concern for accurately assessing their capabilities. While research has thoroughly investigated the impact of test set contamination on discriminative evaluations like multiple-choice question-answering, comparatively little research has studied the impact of test set contamination on generative evaluations. In this work, we quantitatively assess the effect of test set contamination on generative evaluations through the language model lifecycle. We pretrain language models on mixtures of web data and the MATH benchmark, sweeping model sizes and number of test set replicas contaminating the pretraining corpus; performance improves with contamination and model size. Using scaling laws, we make a surprising discovery: including even a single test set replica enables models to achieve lower loss than the irreducible error of training on the uncontaminated corpus. We then study further training: overtraining with fresh data reduces the effects of contamination, whereas supervised finetuning on the training set can either increase or decrease performance on test data, depending on the amount of pretraining contamination. Finally, at inference, we identify factors that modulate memorization: high sampling temperatures mitigate contamination effects, and longer solutions are exponentially more difficult to memorize than shorter ones, presenting a contrast with discriminative evaluations, where solutions are only a few tokens in length. By characterizing how generation and memorization interact, we highlight a new layer of complexity for trustworthy evaluation of AI systems.

trlX: A Framework for Large Scale Reinforcement Learning from Human Feedback

8 December 2023

EMNLP

Reinforcement learning from human feedback (RLHF) utilizes human feedback to better align large language models with human preferences via online optimization against a learned reward model. Current RLHF paradigms rely on Proximal Policy Optimization (PPO), which quickly becomes a challenge to implement and scale up to large architectures. To address this difficulty we present the trlX library as a feature-complete open-source framework for RLHF fine-tuning of models up to and exceeding 70 billion parameters. We implement support for multiple types of distributed training including distributed data parallel, model sharded, as well as tensor, sequential, and pipeline parallelism.To increase the accessibility of RLHF to researchers, we implement compute- and memory-saving features that give trlX the flexibility to support users with a wide range of compute resources. This includes offline RL methods like Implicit Language Q Learning (ILQL), low-rank adapters, and the Hydra architecture. We find offline fine-tuning offers competitive performance relative to online algorithms while being easier to implement, train, and scale. To evaluate our framework we train RLHF models on two separate well-known tasks using publicly available human preference data. Models trained with trlX achieve preference win-rates over baselines at rates comparable to the original works.

Anomalous tokens reveal the original identities of Instruct models

9 February 2023

Alignment Forum

I was able to use the weird centroid-proximate tokens that Jessica Mary and Matthew Watkins discovered to associate several of the Instruct models on the OpenAI API with the base models they were initialized from. Prompting GPT-3 models with these tokens causes aberrant and correlated behaviors, and I found that the correlation is preserved between base models and Instruct versions, thereby exposing a "fingerprint" inherited from pretraining.I was inspired to try this by JDP's proposal to fingerprint generalization strategies using correlations in model outputs on out-of-distribution inputs. This post describes his idea and the outcome of my experiment, which I think is positive evidence that this "black box cryptanalysis"-inspired approach to fingerprinting models is promising.

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

EleutherAI provides a masterclass in signal-to-substance alignment, maintaining a low BS score through extreme technical specificity. The only significant ‘bullshit’ detected is a lack of technical trust infrastructure (schema and outbound link metadata) rather than deceptive content. It is a rare example of a site that under-promises and over-delivers technical proof.

Integrate Organization schema and Person schema for principal investigators to link them to verified academic profiles. Convert the text-based arXiv and conference citations into machine-readable outbound links to resolve the proof_path_absence penalty. Update the meta_description on all pages to move beyond generic titles and include specific expertise to improve technical SEO authority. Explicitly state the relationship between the ‘review_count’ metadata and its real-world source to clear the trust theatre flag.

The site is an exact match for the Science, Research & Laboratories category, specifically positioned as an open-source AI research organization. The content is heavily focused on technical deliverables including datasets (Proof-Pile-2), libraries (trlX), and specific model architectures (LLeMA, Pythia).

“The score of 21 is driven primarily by the Trust and Proof pillar (13/20) due to a forensic mismatch between review counts and verified proof links in the metadata. The Identity and Authority pillar (5/15) also contributed points for missing structured data links to named experts. The core content (Information Density and Semantic Coherence) scored near perfect, indicating a highly credible site.”
