Why this result

Claude Fable 5 is clearly ahead on the BenchAlign aggregate, 83.68 to 69.75. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Claude Fable 5's sharpest advantage is in coding, where it averages 89.2 against 72.2. The single biggest benchmark swing on the page is SWE-bench Pro, 80% to 59%. MiniMax M3 does hit back in multimodal & grounded, so the answer changes if that is the part of the workload you care about most.

Claude Fable 5 is also the more expensive model on tokens at $10.00 input / $50.00 output per 1M tokens, versus $0.30 input / $1.20 output per 1M tokens for MiniMax M3. That is roughly 41.7x on output cost alone. Claude Fable 5 is the reasoning model in the pair, while MiniMax M3 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Claude Fable 5 gives you the larger context window at 1M+, compared with 1M for MiniMax M3.
