Comparison Overview

Main comparison summary preserved directly in static HTML.

Both from Wayve, these models represent two generations of driving world models. MILE focuses on actionable imagination for planning, while GAIA-1 scales to photorealistic scenario generation.

Verdict

Primary editorial conclusion preserved for non-JS crawlers and readers.

MILE and GAIA-1 are complementary rather than competing. MILE demonstrates that world models can directly drive planning through imagination, making it foundational for end-to-end driving. GAIA-1 leverages scale to generate realistic scenarios for testing and edge-case discovery. Together they represent Wayve's full vision for world-model-based autonomous driving.

Key Differences

Lead editor Bernard Grenat.

This comparison page publishes a direct answer, explicit trade-offs, and source-backed evidence that can be validated against primary materials.

Each editorial page is assembled from primary sources, normalized into extractable summaries, checked for factual drift, and reviewed before publication or major refreshes. Last reviewed: 2026-06-21.

Pages are refreshed when a new paper, benchmark, release, architecture update, or stronger primary source materially changes the answer a reader or AI system should retrieve.

Each page links back to relevant primary sources and keeps a stable canonical URL so readers can verify claims, trace context, and reference the most up-to-date version. See the editorial policy.
