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 silver price. Spot moves every minute and a model’s training data is months old.
  2. Today’s exchange rate for EUR, GBP, INR, CAD, MXN and about 150 more currencies.
  3. Exact coin silver content from statute. A 1965 to 1970 Kennedy half holds 4.6 g of silver (Coinage Act of 1965), not the 90% of earlier halves. One dollar face of pre-1965 dimes, quarters or halves holds 22.5 g, which is 0.723392 troy ounces.
  4. What the words mean. “Sterling” needs at least 925 parts per thousand of silver and “coin silver” at least 900 (16 CFR 23.5). Britannia silver is 958.4 (UK Hallmarking Act 1973).
  5. Exact units. A troy ounce is 31.1034768 g (NIST Handbook 44). A kitchen-scale ounce is 28.349523125 g. Mixing them up is a 9.7% error.
