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 low-cost Google model to trial, but plan for its introductory pricing to end.
Gemini 3.8 Flash is worth testing when keeping API costs down is a priority. Its current rates are introductory, so check Google's pricing page for when they end and build that into any longer-term budget. The independent results were measured at a high reasoning setting. Don't assume the Flash name means it will be fast in your setup, or that a low token price guarantees a low cost per finished task; measure both in your own workflow.
