Melanie Mitchell Sparks Fresh Debate Over "Stochastic Parrots" and What Counts as an LLM
On September 27, Santa Fe Institute professor Melanie Mitchell posted on X that "what we have now are not LLMs," sparking a chain of heated exchanges among researchers over the Stochastic Parrots paper and the definition of "LLM." Mitchell's core argument: a language model, by its original meaning, is a system that captures the statistical structure of language (n-gram models, Elman networks, and GPT-2 all qualify), whereas today's AI systems have undergone extensive post-training and incorporate numerous external software components, putting them beyond that scope; therefore, using "stochastic parrots" to criticize today's systems is a straw man—the paper was aimed at the LLMs of 2021.
Confirmed
- Mitchell and Boaz Barak (University of Chicago) clashed over definitions: Barak pressed on whether "LLM" and "stochastic parrot" only apply to pre-InstructGPT models, noting that people were always going to keep calling today's systems LLMs; Mitchell responded with a long post reiterating her understanding of the "language model" lineage.
- Google DeepMind researcher Andrew Lampinen posted a lengthy thread systematically rebutting the core technical claims of the Bender & Koller paper, arguing that systems trained on language alone can still learn meaning, and calling the "stochastic parrot" phrase itself "much noise, signifying nothing."
- Blanche Minerva of Redwood Research laid out a five-step pipeline (pretraining, teaching tool-calling tokens, teaching the command line, etc.) to counter the claim that "LLMs are just next-token predictors," and asked Mitchell: is a transformer with command-line access that can run programs a stochastic parrot, and does the verdict depend on how it was trained? mmitchellai responded that he and Emily Bender had written a piece explaining how "stochastic parrot" refers to LLMs.
- Timnit Gebru, one of the paper's authors, tweeted that she has no interest in engaging with people who keep harping on the argument, asking "why does an accurate description of LLMs upset you so much"; cloneofsimo quote-tweeted with an image in response.
- Other voices backing Mitchell: Brad Buchsbaum said the paper "aviarized" LLMs; tallinzen, unusually siding with the paper, argued that using today's systems to attack it is anachronistic. @aidanclark separately mocked current models as far from ASI using a botched imagegen output.
Unconfirmed
- No consensus on the boundaries of "LLM": whether systems after RLHF and tool use still count as language models, and whether the "stochastic parrot" critique is thereby invalidated, remain open disagreements with no settled conclusion.
Why it matters
- The dispute touches on whether one of the most-cited critical frameworks in AI still applies: if today's systems differ in constitution and capability from the LLMs of 2021, much of the safety and ethics discourse around "stochastic parrots" may need recalibrated terminology and targets.
