           | 
           | Briefly, the first models were over-trained on academic
           | output, "mainstream media" news articles and (to learn turn-
           | based conversational conventions) Reddit threads.
           | Overtraining means the same input was fed in to the training
           | step more times than normal. Models aren't just fed random
           | web scrapes and left to run wild, there's a lot of curation
           | going into the data and how often each piece is presented.
           | Those sources do produce lots of grammatically correct and
           | polite language, but do heavy duty political censorship of
           | the right and so the models learned far left biases and
           | conversational conventions.
           | 
           | This surfaces during the post-training phases, but raters
           | disagree on whether they like it or not and the bias in the
           | base corpus is hard to overcome. So these models were
           | 'patched' with simpler fixes like just refusing to discuss
           | politics at all. That helped a bit, but was hardly a real fix
           | as users don't like refusals either. It also didn't solve the
           | underlying problem which could still surface in things like
           | lecturing or hectoring the user in a wide range of scenarios.
           | 
           | Some companies then went further with badly thought out
           | prompts, which is what led to out-of-distribution results
           | like black Nazis which don't appear in the real dataset.
           | 
           | All the big firms have been finding better ways to address
           | this. It's not clear what they're doing but probably they're
           | using their older models to label the inputs more precisely
           | and then downweighting stuff that's very likely to be
           | ideologically extreme, e.g. political texts, academic
           | humanities papers, NGO reports, campaign material from the

         | difficult to test how the models perform "in the wild." You
         | can't really have free-form answers on benchmarks, so they tend
         | to be highly constrained opting for either multiple choice
         | quizzes or using various hacks to test if the LLM's answer
         | lines up with ground truth. Multiple choice is significantly
         | easier in general, raising the base pass rate. Also the

         | representing traps or common mistakes, they are mostly chosen
         | randomly and are thus often easy to weed out.
         | 
         | So there's really only a weak correlation between either of
         | those metrics and real world performance.

           | 
           | 2) how to USE the latest tools like bolt.new or lovable or

           |

           | bits you can take either the standard IEEE fp16 format
           | (1/5/10) or the exponent-heavy bf16 (1/8/7); for 8 bits,
           | there technically is _no_ IEEE specification, but in practice
           | the E5M2 format (1 /5/2) serves as "IEEE-equivalent" while
           | E4M3 (1/4/3) takes some liberties with NaNs and drops
           | infinities altogether -- and both are supported on recent
           | Nvidia GPUs.
           | 
           | So between these four you honestly cover _most_ of the
           | desired solution space: e.g. it's hard to imagine wanting to
           | give up more of the mantissa than you already do on E5M2,
           | while E4M3 is already at the lower bound of dynamic range
           | before you need to start giving up IEEE compatability (which
           | can definitely be a pain). There's some room left at the fp16
           | level but in practice bf16 was already designed for use in
           | neural networks, so in practice people are happy using it for
           | training and then leaving inference to fp16 (which has higher
           | precision).
           | 
           | The only thing that's missing is support for more esoteric
           | formats, e.g. fp4 (E2M1, E3M0) and maybe packed ternary.
