New attention architecture.

First-ever 5M-token context. 10× lower cost.

Latent Graph Attention is the world's first sub-quadratic attention architecture — delivering up to 10× faster inference at 512K context and the first-ever 5M-token context window, without loss in reasoning quality.

01 / Latent Graph Attention

Latent Graph Attention— An architectural breakthrough.

Breakthrough

Antilattice is the first architecture built on Latent Graph Attention — a fully learned, graph attention mechanism that routes compute only to the token relationships that matter, instead of processing every possible pair. At 512K tokens, this makes inference 10× faster (512K) and 100× faster (5M), making a 5M-token context window possible for the first time in the world.

And we're not stopping there. The same architecture is built to scale to 10–15M tokens without performance loss, putting us at the forefront of the technology needed to make true ultra-long context real, for the first time in the world.

Internal benchmarking on a vLLM-based serving stack, normalized to short-context throughput (8K = 100). The dense-attention baseline becomes memory-infeasible to serve past roughly 512K–1M tokens on the same hardware; Antilattice keeps scaling.

03 / Built for

The workloads that outgrow dense attention

Agentic systems

Long-horizon agents

Agents that accumulate tool calls, memory, and multi-turn state across hundreds of thousands of tokens — without truncating history or losing earlier context to make room for new turns.

Enterprise

Document intelligence at full scale

Reason across an entire contract set, filing archive, or knowledge base in a single context window, instead of stitching together an answer from chunked retrieval.

Developer tooling

Whole-repository code reasoning

Give coding agents and review tools the entire repository as context — dependencies, tests, and history included — instead of a handful of retrieved files.

Infrastructure

Cost-sensitive scale

Serve long-context requests at a per-token cost that doesn't compound with usage, so long context stops being the tier you ration and starts being the default.

04 / The bottleneck

Long context was never free — it was deferred

Fig. 01 — every pair computed

Compute is the visible cost

Dense attention costs FLOPs quadratically: double the context, quarter the throughput. That cost is easy to see on a spec sheet, so most optimization work goes toward computing that full grid faster — a better kernel, a bigger batch, more GPUs.

Fig. 02 — KV cache vs. HBM ceiling

Memory is the quieter one

The KV cache grows linearly with context and has to live in HBM for the entire generation. Long before compute becomes the limit, cache pressure forces smaller batches, shorter effective context, or both — and throughput collapses well ahead of any theoretical FLOPs ceiling.

Fig. 03 — claimed vs. served

Support is not the same as serving

Most "long-context" support today is a checkbox in a spec sheet: the model accepts the tokens, but serving it at real latency and real cost is a different problem entirely. Solving it means rethinking which token pairs are worth attending to in the first place — not just computing all of them faster.

How to read it

  • FLOPs ~O(n²)Compute cost quadruples every time context doubles. At 512K you're paying 4,000× what you paid at 8K.
  • KV cache O(n)Memory grows linearly but must stay resident in HBM. At long context, it exhausts the GPU before compute does.
  • AntilatticeLatent Graph Attention keeps cost near-linear in effective context. The serving limit never arrives.
