It's counterintuitive, but using a more expensive, intelligent model like Opus 4.5 can be cheaper than smaller models. Because the smarter model is more efficient and requires fewer interactions to solve a problem, it ends up using fewer tokens overall, offsetting its higher per-token price.

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.

The release of models like Sonnet 4.6 shows that the industry is moving beyond singular 'state-of-the-art' benchmarks. The conversation now focuses on a more practical, multi-factor evaluation. Teams now analyze a model's specific capabilities, cost, and context window performance to determine its value for discrete tasks like agentic workflows, rather than just its raw intelligence.

AI labs like Anthropic find that mid-tier models can be trained with reinforcement learning to outperform their largest, most expensive models in just a few months, accelerating the pace of capability improvements.

Despite significant history and memory built up in platforms like ChatGPT, power users quickly abandon them for models like Claude or Manus that provide superior results. This indicates that output quality is the primary driver of adoption, and existing "memory" is not a strong enough moat to retain users.

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.

While ChatGPT has wider general usage, Claude is the preferred primary tool for the most engaged AI users. These users leverage AI for more hours, engage in more complex 'agentic' tasks, and report higher value gains, indicating Claude's strength with the advanced builder/practitioner segment.

Sonnet 4.6's true value isn't just being a budget version of Opus. For agentic systems like OpenClaw that perform constant loops of research and execution, its drastically lower cost is the primary feature that makes sustained use financially viable. Cost efficiency has become the main bottleneck for agent adoption, making Sonnet 4.6 a critical enabler for the entire category.

Tasklet's CEO points to pricing as the ultimate proof of an LLM's value. Despite GPT-4o being cheaper, Anthropic's Sonnet maintains a higher price, indicating customers pay a premium for its superior performance on multi-turn agentic tasks—a value not fully captured by benchmarks.
