Editorial excerpt
A specialist option for difficult, high-value work where token cost comes second.
Fable 5.1 is best considered for the hardest end of the work: complex reasoning and coding problems where a better answer is worth paying for. Its API rates are among the highest of the models we rank, so it is difficult to justify for routine or high-volume tasks. The sensible approach is to test it on a handful of genuinely difficult problems and judge the finished results yourself. Bear in mind that the independent results were measured at the model's top reasoning setting.
Editorial excerpt
A new Google reasoning model worth trialling for hard technical work, with launch pricing that needs a review date.
Gemini 4 Argon is worth adding to a shortlist for demanding technical work, such as complex coding or multi-step analysis, where a better answer saves real time. Its current API rates are introductory, so check Google's pricing page for when they change and budget for the standard rate rather than the launch price. The independent results were measured at a high reasoning setting, which may differ from your own configuration. As with any new release, test it on a few real tasks before moving important work across.
