Fireworks Lab launches Gen-1 Slides, matching Claude Opus 5 at lower cost · 5 sources tracked

By PulseAugur Editorial · [5 sources] ·

Fireworks Lab has released Gen-1 Slides, an open model for slide generation that matches Claude Opus 5's performance at a significantly lower cost. This model was co-developed with Genspark AI, which provided product judgment and real-world production environments for training. The development involved long-horizon reinforcement learning, with Fireworks Lab handling the infrastructure and algorithm co-development, and Genspark AI focusing on product direction and evaluation. AI

IMPACT Sets a new benchmark for cost-effective slide generation, potentially impacting tools and services reliant on presentation creation.

    The hardest bugs were numerical. Long-horizon RL drifts when the engine generating rollouts and the one scoring them stop assigning the same probabilities to the same tokens. Aligning tokenization across both kept the training signal trustworthy.

    Genspark owned the product judgment. They brought their real production environment into training and shaped what the model optimized for: the standard for a good deck, the design principles behind it, and how to sharpen that standard over time.
