Pricing Update for GPT-5.6 Sol
GPT-5.6 Sol, the frontier model within the GPT-5.6 family, has undergone a significant price reduction. Input tokens are now priced at $4 per million, a 20% decrease from previous rates. Output tokens have seen an even larger reduction, now costing $20 per million, which is a 33% decrease.
Model Details and Aliases
GPT-5.6 Sol corresponds to the unsuffixed model tier found in earlier GPT-5 families. The 'gpt-5.6' alias routes requests directly to GPT-5.6 Sol, simplifying access for users. The model supports various reasoning effort levels, including none, low, medium (default), high, xhigh, and max.
Promotional Period and Special Conditions
The new promotional pricing for GPT-5.6 Sol is guaranteed to be available at least through November 21, 2026. Users should note that prompts exceeding 272,000 input tokens will incur different rates, specifically 2x for input and 1.5x for output on the full request. Additionally, cache writes are billed at 1.25 times the uncached input token rate.
Impact on AI Development
This pricing adjustment makes the advanced capabilities of GPT-5.6 Sol more economically viable for a broader range of applications and developers. The reduced cost of both input and output tokens can lower operational expenses for AI-powered services and products, potentially encouraging wider adoption and experimentation with the model's features.
