B.AI has launched Grok 4.6 on its API, saying the model marks a broad upgrade from Grok 4.5 in complex task handling, deep reasoning and overall intelligence. The platform said Grok 4.6 also showed clearly leading performance in the GPDVal-AA V2 evaluation, widening its use in large-scale reasoning and other high-difficulty task scenarios. The release includes two access routes, an official channel and a user-selected service provider channel, alongside an exclusive Mix offer from official and user-selected providers at a 40% discount, aimed at giving developers more flexibility and lower integration costs. Users can access the upgraded capabilities through the B.AI API immediately.
