What exactly do Wayve's GAIA-2, GAIA-3 and GAIA-4 pages claim about fidelity, controllability and correlation with real driving, and which of those claims come with a value?

Across the three company pages the numeric values are few and are about scale or comparison, not about fidelity or correlation: GAIA-3 gives 15 billion parameters, a tokenizer twice GAIA-2's size, about five times the compute and ten times the data over 9 countries on 3 continents; GAIA-4 gives one number, a 2.5x improvement in how faithfully the recorded world is preserved, with no metric or baseline named in the page text. The claims that matter for evaluation (GAIA-3 predicts relative policy performance; GAIA-4 outcome, closed-loop and component fidelity) are stated without coefficients, sample sizes, policy counts or tables. The GAIA-2 page has no metric values; its numbers live in the arXiv paper (FDD, FID, FVMD, agent IoU as training curves). Curator qualifications: Scale values verified; the only GAIA-4 number is 2.5x. ADDENDUM-002 rewords 'no metric or baseline named' to 'no measurement method or numeric baseline given' (the quantity is loosely named and the comparison is implicitly a general-purpose world model); curator agrees with the addendum wording. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary. Limitations: [component_reuse_restriction] Company pages (all rights reserved); quote briefly. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
