Meta releases Lattice 1.2 with improved context windows for dialogue-driven prototyping

Tech · 4 min read

Lattice 1.2 extends both token window and structured memory capabilities so design assistants can consider weeks of conversation history when proposing changes. This enhances continuity in iterative projects where goals and constraints evolve over multiple sessions.

The model introduces a memory-ranking module that surfaces the most relevant past decisions to justify current suggestions. Meta also shipped collaboration features like comment anchoring to model outputs and role-based generation controls.

Some teams are excited about fewer repeat prompts and better historical reasoning, while privacy advocates asked for clearer export controls for stored memories. Meta responded by adding team-level retention settings and export tooling.
