Colombian exports reached $32.489 billion FOB between January and July 2026, representing a 12.7% increase compared to the same period in 2025. [^1]

Researchers studied two signals accessible through black-box model APIs to detect fabrications: semantic entropy, which measures disagreement among sampled response meanings, and uncertainty derived from token log-probabilities. [^2]

According to the Dane, hydrocarbons and fuels totaled $13.142 billion in the first seven months of 2026, an increase of 16.6% compared to the same period in 2025. [^3]

The authors concluded that no method is universally strongest for hallucination detection in black-box LLMs. [^4]

The Stacked supervised method, which learns jointly from semantic uncertainty and broader token features, gave the best performance in nearly half of the evaluated cases. [^5]

The study evaluated seven benchmarks, including five public datasets and two constructed benchmarks (Financial Summaries and Long-Text QA), using four language models. [^6]
