This is probably the wrong place to ask this, but does anyone know how Anthropic's Claude is so good? I know about their Constitutional AI approach, but afaik that's for alignment and ethics. Purely qualitatively the bandwidth of understanding between myself and the model is notably wider. It's hard to describe the difference between it and e.g. GPT-4 without anthropomorphizing, but it reasons so damn well and essentially never hallucinates.

Also, strangely, and somewhat unnervingly, it makes occasional rudimentary typos and grammatical mistakes. What would cause that?

Some examples:

• "So in summary, you raise a excellent point that the accumulation of mutations over vast timescales should not necessarily devastate organisms or wildly transform their morphology and nature."

• "There aregood opportunities for advancing knowledge through experimental and theoretical exploration of adaptive mutation and evolvability in cells and at other levels of life."
