For an AI sales assistant, Claude Sonnet 4.5 wins by offering the perfect balance of high-speed responses and cost efficiency without sacrificing conversational intelligence. While GPT-5.2 Pro excels at complex multi-step negotiations, its premium pricing makes it less viable for high-volume lead qualification.

Claude Sonnet 4.5
At $3 per 1M input tokens and $15 per 1M output tokens, Sonnet 4.5 keeps customer acquisition costs extremely low even at scale.
GPT-5.2 Pro
At $10 per 1M input tokens and $30 per 1M output tokens, GPT-5.2 Pro is significantly more expensive, making it hard to justify for high-traffic top-of-funnel interactions.

The massive 256K token window allows the agent to reference extensive customer histories, enterprise SLA documents, and complex API documentation simultaneously.
Claude Sonnet 4.5
Sonnet 4.5 is highly steerable and rarely hallucinates outside its system prompt, making it incredibly easy to configure for specific sales pipelines.
GPT-5.2 Pro
While highly capable, GPT-5.2 Pro's advanced tool-use capabilities require more complex prompt engineering to prevent it from over-complicating simple sales inquiries.
$3/1M input, $15/1M output
$10/1M input, $30/1M output
Claude Sonnet 4.5 is over 3x cheaper for input tokens and exactly half the price for output tokens compared to GPT-5.2 Pro. For a sales assistant processing 10,000 lead conversations a month (averaging 2,000 input and 500 output tokens per chat), Sonnet 4.5 would cost around $135, whereas GPT-5.2 Pro would cost $350. This makes Sonnet 4.5 the clear financial winner for high-volume deployments via CloudClaw.
