While faster model versions like Opus 4.6 Fast offer significant speed improvements, they come at a steep cost—six times the price of the standard model. This creates a new strategic layer for developers, who must now consciously decide which tasks justify the high expense to avoid unexpectedly large bills.

Analysis of Anthropix's OPUS model reveals a strong user preference for speed, with customers willing to pay six times more for a model that is only two times faster. This disproportionate willingness to pay for performance validates the market for specialized, high-speed inference chips like those from Cerebras.

The importance of speed in AI is deeply psychological. Similar to consumer packaged goods where faster-acting ingredients create higher margins and brand affinity, low-latency AI creates a powerful dopamine cycle. This visceral response builds brand loyalty that slower competitors cannot replicate.

As frontier AI models reach a plateau of perceived intelligence, the key differentiator is shifting to user experience. Low-latency, reliable performance is becoming more critical than marginal gains on benchmarks, making speed the next major competitive vector for AI products like ChatGPT.

When evaluating AI agents, the total cost of task completion is what matters. A model with a higher per-token cost can be more economical if it resolves a user's query in fewer turns than a cheaper, less capable model. This makes "number of turns" a primary efficiency metric.

Companies like OpenAI and Anthropic are intentionally shrinking their flagship models (e.g., GPT-4.0 is smaller than GPT-4). The biggest constraint isn't creating more powerful models, but serving them at a speed users will tolerate. Slow models kill adoption, regardless of their intelligence.

Frame the value of speed beyond just a better user experience. Ask customers how they could use the time saved by faster AI responses to pack in more value, create premium product tiers, or open entirely new revenue streams that were previously impossible.

Previously, the biggest constraint in AI was compute for training next-gen models. Now, the critical bottleneck is providing enough compute for *inference*—the real-time processing of queries from a rapidly growing user base.

While training has been the focus, user experience and revenue happen at inference. OpenAI's massive deal with chip startup Cerebrus is for faster inference, showing that response time is a critical competitive vector that determines if AI becomes utility infrastructure or remains a novelty.
