What it answers that a model cannot answer alone

A language model answers from training data that is months old and does arithmetic from memory. This server returns the current figure with its source. In the words of its README, it knows these things that your model does not.

  1. Today’s gold price. Spot moves every minute and a model’s training data is months old.
  2. Today’s exchange rate for INR, AED, SAR, PKR, EUR, GBP and about 150 more currencies.
  3. Exact unit constants. A troy ounce is 31.1034768 g and a grain is 64.79891 mg by definition (NIST Handbook 44). A tola is 180 grains. A Thai bullion baht is 15.244 g, not 15 g. A kitchen-scale ounce is 28.349523125 g, not a troy ounce.
  4. Karat purity as an exact fraction (karat / 24), so 22K is 91.6667% and 14K is 58.3333%.
