About This Tool

The tool provides a structured, model-agnostic way to interpret how transformer decoders process tokens by exposing attention distributions and token-to-token interactions.
Conceptually, the system ingests model_type, input sequence, and configuration, computes attention and (optionally) gradient-based relevance, and presents per-layer and per-head summaries along with decoded paths.
Beneficiaries include researchers, ML engineers, and QA teams seeking transparency, reproducibility, and debugging insights for transformer-based systems. Unique value lies in focus on decoder-centric pathways, encoder-decoder cross-attention, and exportable interpretability reports.
Core features include attention matrix extraction, head-level summaries, token mappings, path scoring, and report export. Use cases cover model auditing, failure analysis, and research into attention behaviors across architectures.

How to Use

Provide inputs: specify model_type (encoder/decoder/encoder-decoder), supply the token sequence, and optional decoding_mode.
Configure limits and options: set max_tokens, attention_threshold, and any advanced mode.
Run analysis: execute the decoding to produce attention maps, token mappings, and path scores.
Review outputs: inspect per-token interactions, head and layer summaries, and export options.
Export results: download JSON or CSV reports for offline analysis.

Frequently Asked Questions

Find Quick Answers

What does the tool decode?

The tool decodes transformer outputs into token-to-token interactions, attention distributions, and path scores, enabling interpretation of how attention flows through layers and heads without requiring model training.

Which models are supported?

The tool supports common transformer architectures, including encoder-only, decoder-only, and encoder-decoder variants (e.g., BERT, GPT-2, T5), with cross-attention handling where applicable.

What data formats are required?

Inputs should include a token sequence and corresponding model outputs (attention matrices, logits) in a defined schema; outputs are provided as JSON with tokens, matrices, and summaries.

Is data private?

Data is processed within your environment; the tool does not transmit data to external services unless you opt in. It does not modify or train any models during analysis.
