What the article says around this equation
The concrete number is what makes this a case about verification rather than a stylistic quibble. Once LMArena added the actual public release to its board and ran it through the identical crowdsourced comparison used for the experimental variant, the vanilla Llama-4-Maverick-17B-128E-Instruct settled at 32nd place — below OpenAI’s GPT-4o, Anthropic’s Claude 3.5 Sonnet, and Google’s Gemini 1.5 Pro, all models that were, by April 2025, already a generation or more behind the frontier [ 9 ] . The gap between second place and thirty-second place is not the kind of thing an evaluation-harness flag explains. It is the kind of thing that only becomes checkable at all because the actual released…

The concrete number is what makes this a case about verification rather than a stylistic quibble. Once LMArena added the actual public release to its board and ran it through the identical crowdsourced comparison used for the experimental variant, the vanilla Llama-4-Maverick-17B-128E-Instruct settled at 32nd place — below OpenAI’s GPT-4o, Anthropic’s Claude 3.5 Sonnet, and Google’s Gemini 1.5 Pro, all models that were, by April 2025, already a generation or more behind the frontier [ 9 ] . The gap between second place and thirty-second place is not the kind of thing an evaluation-harness flag explains. It is the kind of thing that only becomes checkable at all because the actual released could be independently obtained and run through the same public arena the showcased variant had been run through — an outsider held the released weights, and holding them was what made “which model actually scored this” answerable rather than assumed.
