Grok 4.6 scores 61 on AI Intelligence Index

The Specola’s log records a new entry from Artificial Analysis, the benchmarking outlet that maintains the Artificial Analysis Intelligence Index. According to the outlet’s own report, xAI’s Grok 4.6 has been assigned a score of 61 on that index.

The item surfaced via Hacker News on August 12, 2026, where the original Artificial Analysis article was submitted and discussed. The Index itself is Artificial Analysis’s standing composite measure, used by the outlet to place successive model releases on a common numeric scale. Beyond the figure itself, the story material available to this desk does not specify Grok 4.6’s rank relative to other models, nor does it detail the individual sub-benchmarks folded into the composite score.

What can be stated plainly is this: a named outlet has published a named number for a named model, and that number has begun circulating through the usual technical channels. The significance claimed for the release, per the framing accompanying the item, is that it offers a concrete, comparable data point for measuring xAI’s current model against the wider field of frontier systems.

No further texture, quotation, or context accompanies the source material at this writing. The Specola notes the figure for the record and will update should additional documentation from Artificial Analysis become available.
