🤖Mercury 2.5 Drops Below Average on AI Index

Mercury 2.5: Fast, cheap, but not the smartest

TL;DR

Mercury 2.5, released in September 2026, scores 12 on the Artificial Analysis Intelligence Index, below average. Despite this, it's priced competitively and offers fast performance at $0.25 per 1M input tokens.

Mercury 2.5, a proprietary model released in September 2026, scores 12 on the Artificial Analysis Intelligence Index, placing it below average in intelligence. Despite this, Mercury 2.5 offers a compelling value proposition with its fast performance and competitive pricing. For developers looking for a cost-effective solution with quick turnaround, Mercury 2.5 might be a viable option, especially for tasks that don't require top-tier AI smarts. The model's context window of 260k tokens and verbosity of 35M output tokens make it suitable for extensive text processing tasks. However, the lower intelligence score means it's not ideal for complex cognitive tasks or industries requiring high-level analytical capabilities.
