The development
A structural analysis of AI infrastructure reveals systematic disadvantages for underrepresented language speakers, using Bengali as a case study. The research identifies four critical failures: Bengali comprises less than 0.5% of web training data despite representing 4% of global population, creating a 67:1 token deficit relative to speaker population. These gaps originate upstream in corpus collection, tokenization design, and benchmark construction, not in model training itself. The findings challenge the narrative that scaling AI alone solves access gaps in low-connectivity regions, suggesting that infrastructure choices embed language inequality before deployment begins.

The paper's core finding is that language inequality isn't primarily a model training problem but a data collection and tokenization problem baked in much earlier. This reframes where the actual bottleneck sits and suggests that simply scaling compute or parameters won't fix it.
Recent coverage has focused on what language models can extract and do once deployed (like the financial sentiment analysis work from August 12th), but this research identifies a hard constraint that exists before any model ever trains. That financial NLP work assumes the model has sufficient linguistic capacity to parse nuance; this paper shows that capacity is systematically withheld from Bengali speakers at the infrastructure layer. The two stories together suggest that LLM capability gains are unevenly distributed not by accident but by design choices made in corpus construction.
If researchers release a Bengali-specific corpus or tokenizer that closes even half the 67:1 token deficit and demonstrate measurable performance gains on Bengali benchmarks within the next 12 months, that signals infrastructure fixes are tractable. If no such intervention appears and Bengali LLM performance stagnates despite general model scaling, the paper's claim about upstream bottlenecks will have held.

LLMs extract richer trading signals than sentiment lexicons in small-cap portfolios
Researchers demonstrate that language models can extract nuanced sentiment signals from financial news more effectively than traditional lexicon-based approaches, with practical application to small-cap equity trading. The work advances portfolio construction by decomposing model-predicted risk into aleatoric and epistemic uncertainty, feeding both directly into covariance matrices rather than treating risk as static. Testing across Russell…
