HIDDEN STATE SIMULATOR · TECHNICAL SPECIFICATION
Long history. Compact memory.
Local decoding.
Instead of repeatedly carrying full context history through every decoding step, AVIKRAT introduces a compact hidden-state representation that persists across long-running LLM inference passes.

- [01]
Long History Stream
Expanding input sequence context enters the system pipeline.
- [02]
Global Prefill Pass
Full context history is processed once to construct hidden state representations.
- [03]
State Compression
Sequence representations collapse into a compact persistent vector.
- [04]
Persistent Vector Core
Small fixed-size hidden state persists across subsequent inference turns.
- [05]
Local Window Buffer
Only recent tokens remain active in the local decoding cache.
- [06]
Local Decode Execution
Local attention pass resolves against persistent state to emit next token.
PIPELINE SPECIFICATION · HIDDEN STATE SIMULATOR MODEL
The Problem
The old assumption: keep carrying the context.
Traditional long-context inference treats history as a growing payload. Every added token expands the KV cache, and every decoding step re-reads more of it — so memory, latency, and serving cost climb together.

The Shift
What if long history
became state?
AVIKRAT's approach is based on a simple architectural shift: process the long history globally, preserve the useful information in a compact persistent state, and use a short local token window for ongoing decoding.

Instead of re-reading the full context at every step, the long history is read once by a global prefill and collapsed into a dense, fixed-size representation. The full original tokens are no longer carried forward — the state is.
Ongoing decoding then operates on that persistent state plus a short recent window, so the active working set stays bounded as the conversation grows.
This is a conceptual image of the intended architecture, not a measured model.
The Pipeline
Four stages. One persistent state.
Each stage is a single, well-defined step. Together they describe how the simulator intends to turn unbounded conversations into bounded compute.

Global Prefill
Read the full history once.

Compact State
Persist a small learned memory.

Local Decode
Use a short recent window only.

Next Token
Generate efficiently.

The Comparison
Two ways to carry context.
One carries everything forward. The other carries a compact state and decodes locally. The difference shows up as context grows.
Traditional Inference
- KV cache grows with every extra token
- Memory and attention cost rise with context length
- Long conversations become increasingly expensive to maintain
Hidden-State Simulator
- Compact persistent state is kept fixed-size
- Local decoding operates on a short token window
- Inference cost is designed to stay much flatter as context increases

Applications
The opportunity is bigger than one model.
A bounded, persistent context opens up workloads where long-running or continuous state currently gets too expensive.
Enterprise Copilots
Persistent conversations and large document sessions.
Edge AI
Smaller persistent memory can be friendlier to constrained devices.
Agent Infrastructure
Long-running workflows can remain active without exploding state cost.
Real-Time Systems
Bounded memory can make continuous context more practical.
Working Simulator
From architecture to working simulator.
A working simulator already predicts hidden-state structure and tracks validation behavior.

This provides the concrete base for next-token perplexity and cost benchmarking.
- True vs Predicted Context Slices
- Error Metrics
- Cosine Similarity
- Checkpoint Selection
The simulator provides these capabilities — no numeric results are claimed.
The Roadmap
The next step is measurement.
The architecture is directional. Turning it into infrastructure means validating each claim against matched baselines and real workloads.
- Perplexity
Quality must remain competitive.
- Latency
Decoding should improve.
- Memory
Memory should remain bounded as context grows.
- Scaling
Measure behavior across increasing context lengths.
Early-stage research targets — no benchmark results are claimed yet.
The Target
Target: up to 90% lower long-context inference cost
The current pitch targets long-context inference cost reduction through compact-state decoding. This target must be validated against matched baselines while maintaining competitive model quality.
