A recent OpenAI paper on genomics has inadvertently revealed a new Pro lineup for GPT-5.6, featuring three models: Luna Pro, Terra Pro, and Sol Pro, which could offer users a choice between speed, throughput, and maximum reasoning power. This would be a significant shift from the current single top-tier Pro model, potentially allowing users to select the best model for their specific needs. The paper’s findings suggest that the Pro variants could provide substantial performance gains, especially for weaker tiers. Why it matters: this potential change could greatly impact the AI landscape by giving users more flexibility and control over their AI tools, which could lead to more widespread adoption and innovative applications.
