What commenters say

• The pricing of GPT-5.6 is expensive and may not be competitive with other options, such as Deepseek.

• The new model's performance is expected to be improved, but some users are skeptical about the value it provides, especially given the cost.
• The concept of a 'next-generation' model is questioned, with some arguing that it should be a major version change, such as GPT-6, rather than a minor update.
• The discussion around GPT-5.6 highlights the challenges of versioning and naming in the context of LLM development, where technical and marketing considerations intersect.
