# Percepta

Percepta is a company innovating at the architectural frontier of LLM design.

**Key innovation**: They compiled a **WebAssembly C-interpreter** directly into the **weight matrix** of a standard PyTorch transformer. This allows the model to perform deterministic computation natively, **without external tool calls** — see [[concept-embedded-deterministic-compute]].

The model literally executes C programs through its forward pass, step-by-step, emitting a stack trace as tokens. This is a paradigm shift from 'LLM calls a tool' to 'LLM natively executes deterministic code in its own weights.'

**Other work**: Percepta is also noted for working on **2D attention heads** to reduce attention complexity.

**Strategic relevance**: Their work materializes the contrarian thesis [[contrarian-llms-not-computers]] — namely, that overcoming the probabilistic limits of neural networks requires fundamentally rethinking the architecture, not just bolting on more tool calls.

**Status (per enrichment overlay)**: No canonical URL found in independent searches; likely an early-stage startup, unverified beyond the source extraction.
