Inference acceleration

Generate the whole response in parallel, not one token at a time

Inception replaces sequential autoregressive generation with diffusion-style parallel decoding: every output position is initialized at once, then refined jointly across K iterations, instead of one token per forward pass.

How parallel decoding works

01

Parallel seed

All output positions are initialized simultaneously in a single forward pass. The model begins with a complete draft of every token at once, rather than producing them one by one left to right.

02

Joint refinement

Each of the K refinement iterations updates every position jointly, so tokens can attend to and influence each other across the full output length throughout the decoding process.

03

Collective convergence

The model converges when all positions reach sufficient confidence together. The output is not a left-to-right stream but a jointly decoded sequence refined until the whole is coherent.

Built for real workloads

Where parallel decoding fits

Interactive dialogue

Conversational assistants

Chat applications where response completeness matters more than streaming individual tokens. Inception produces the entire answer jointly, so the delivered output is globally consistent rather than left-to-right committed.

Structured generation

Documents and code

Long-form outputs such as reports, summaries, and code files that require coherent cross-sentence and cross-function dependencies. Parallel refinement lets late positions inform early ones before anything is committed.

Scale-out pipelines

High-volume batch jobs

Workflows generating large numbers of independent completions simultaneously. The compute constraint shifts from sequential token dependencies to batched parallel decoding, enabling denser utilization of available hardware.
