Formats a byte count into a human-readable string:

typescript
formatBytes(0)       // "0 B"
formatBytes(1024)    // "1.0 KB"
formatBytes(1536)    // "1.5 KB"
formatBytes(1048576) // "1.0 MB"

estimateTokens ​

typescript
function estimateTokens(bytes: number): number

Estimates the token count for a given byte size using the ~4 characters per token heuristic.

formatNumber ​

typescript
function formatNumber(num: number): string

Formats a number with thousands separators:

typescript
formatNumber(1234567) // "1,234,567"

formatTokenEstimate ​

typescript
function formatTokenEstimate(bytes: number): string

Combines estimateTokens and formatNumber into a display string:

typescript
formatTokenEstimate(6000) // "~1,500 tokens"
