Mercury 2.5 LLM hits 770 tokens per second
summary
Mercury 2.5 is a proprietary reasoning model from Inception that prioritizes speed and cost-efficiency over raw intelligence. While it scores below the median for its price tier on the Artificial Analysis Intelligence Index, it offers exceptional output speeds and competitive pricing. This makes it a viable option for users who need fast, concise responses without requiring the highest level of complex reasoning capabilities.
key points
- Mercury 2.5 delivers an exceptionally high output speed of 770.4 tokens per second, significantly outperforming the median speed of 108.6 tokens per second for similar models.
- The model is competitively priced at $0.25 per 1M input tokens and $0.75 per 1M output tokens, making it a cost-effective choice for high-volume tasks.
- It features a 260k token context window and is designed for conciseness, generating fewer output tokens per task compared to the average model in its class.

Developers and businesses looking for a fast, affordable AI model for text-based tasks where extreme intelligence is not the primary requirement.
discussion skeptical
consensus
Commenters generally agree that while Cerebras and similar providers offer extreme inference speeds, the trade-off in intelligence and cost is often prohibitive. High costs due to a lack of input caching and poor reliability in tool calling make the speed irrelevant for most production use cases. There is a shared skepticism regarding the viability of diffusion-based LLMs for general-purpose agentic workflows compared to traditional autoregressive models.
top insight
The utility of extreme speed is context-dependent; specifically, it may be viable for low-latency on-device applications like robotics or voice interfaces where batch sizes are small. In these scenarios, the speed gains of diffusion models are not negated by the hardware sharing inefficiencies that make them impractical for large-scale cloud serving. This suggests a niche rather than a general replacement for current LLM architectures.
