·WHY PARSIM

Built to compress.
Engineered to
reason.

Four algorithmic commitments we hold across every inference pass, from prefill to autoregressive decoding.

16X RATIO

Lossless KV-compression, 16x factor

Built with adaptive attention subspace projection backed by zero-perplexity-drift guarantees.

10M+ TOKENS

10M+ long-horizon context, sustained

Proven stability across million-step agentic execution without degradation or attention sink collapse.

<1.2% O/H

Zero-overhead kernel, Bare-metal CUDA

Hand-tuned FlashAttention-3 and Triton kernels engineered for H100, B200, and TPU v5p clusters.

100% RECALL

Needle-in-haystack recall, 100% deterministic

Designed so no critical instruction or faint semantic dependency is ever dropped in the context abyss.

·The philosophy of Parsim
A system for longer reasoning

Intelligenceshouldscalewiththeproblem,
notthememorybudget.

Our point of view

Context is a resource to steward, not a buffer to fill. Parsim preserves the signals that matter, compresses redundant attention state, and keeps recall deterministic so reasoning can continue across longer horizons.

Compress the overhead

Reduce redundant attention state before memory limits reasoning depth.

Extend the horizon

Let agents carry coherent reasoning further, with deterministic recall.

Deterministic Memory Across 100,000 Step Loops

Autonomous coding and research agents repeatedly crash when prompt history fills standard attention buffers. Parsim retains permanent system prompt anchors while compacting historical reasoning chains.

Subspace Low-Rank Key-Value Head Projection

By dynamically identifying shared attention manifolds across decoder heads, Parsim eliminates up to 85% of redundant key-value tensors before they consume High Bandwidth Memory (HBM3e).
