Early hands-on impressions of GPT-5.6 reveal a massive leap in speed and accuracy. Tasks that previously took hours are now processed extremely fast, and the model exhibits a much friendlier personality. While Fable 5 still leads in broad capabilities, Sol performs exceptionally well on specific tasks. Furthermore, users recommend combining Fable 5 with models like GPT-5.6 Sol Pro into a MoA (Mixture of Agents) architecture to solve the hardest problems, albeit at the cost of massive token consumption.
