30B

30B is a numeric shorthand used in English-language contexts to denote thirty billion, with B standing for billion in the short scale. The exact value is 30 × 10^9. The suffix is employed across various fields to indicate scale when paired with a number, but its meaning depends on the domain and explicit units.

In technology and artificial intelligence, 30B frequently refers to language models that have roughly 30 billion parameters. Models in this size class are considered mid- to large-scale and are commonly used as benchmarks for balancing performance with computational and memory requirements. The term is part of a broader convention that labels models by parameter counts, such as 7B, 13B, 30B, and 65B. It is important to note that parameter count does not directly determine capability, which also depends on architecture and training data.

In finance and business contexts, 30B denotes 30 billion units of currency or other magnitudes, for example 30B USD. Such shorthand is common in summaries, projections, and reports where exact figures are less critical than the scale being conveyed.

Ambiguity can arise because B has different meanings in different domains. In data storage contexts, B can indicate bytes, though 30B is more commonly expressed with explicit units. When encountering 30B, the intended meaning should be inferred from surrounding context, and explicit units are preferred to avoid confusion.
