Meta Launches Muse Ember, Its Smallest and Most Efficient Model for Complex Reasoning

The pricing is the real story here: a reasoning-capable model at commodity-level token rates compresses the cost floor for tasks that previously justified larger, pricier models. That matters most for builders running reasoning-heavy workloads at volume, where inference cost, not raw capability, decides what ships. The open question is whether a model this small holds up on genuinely complex reasoning once developers stress it beyond benchmark-friendly cases — capability at this price point, not the price itself, is what will determine adoption.
