The world's largest AI aggregator platform OpenRouter announced on August 17 on X that it would halve the calling fee for OpenAI's strongest model, GPT-5.6 Sol. This adjustment immediately attracted industry attention, as the model is regarded as OpenAI's most competitive flagship product.
OpenRouter is currently the AI model aggregation platform with the widest global coverage, bringing together large language models from multiple mainstream manufacturers. After this price reduction, GPT-5.6 Sol's input fee per million tokens has dropped from $5 to $2.5, approximately RMB 16.9; the output fee has dropped from $30 to $15, approximately RMB 101.3. IT Home noted that OpenRouter has not yet disclosed whether the discount is time-limited.
Another hosting platform, Vercel, also launched similar offers simultaneously. Vercel announced a limited-time half-price for GPT-5.6 Sol, effective until September 18, 2026, covering both Standard and Fast modes. This means developers can access the model at a low cost within a month for prototype testing or production environments.
Industry analysis media SemiAnalysis believes this is a clever marketing strategy. OpenRouter and Vercel are important data sources for evaluating AI model performance and cost. The half-price discount can significantly lower the trial threshold and attract more developers to switch to GPT-5.6 Sol. As usage increases, the model's ranking and visibility in third-party evaluations are also expected to improve.
This price reduction may intensify price competition in the AI model market. Previously, Anthropic's Claude series and Google's Gemini series have adjusted their pricing strategies, and the discount on GPT-5.6 Sol may force other vendors to follow suit. For small and medium-sized development teams, this is an opportunity to explore complex tasks, such as code generation and long-text reasoning, at a lower cost in the short term.
The industry generally believes that model calling fees remain one of the key factors determining the market landscape. Whether the half-price offer can last depends on business negotiations between OpenAI and hosting platforms, as well as changes in server costs. If the discount becomes the norm in the future, it may further drive the expansion of the AI application ecosystem.
