The AI giant has also released its much awaited ‘superapp’ in the form of ChatGPT Work.
Token efficiency takes centre stage with OpenAI’s latest family of AI models that supposedly outperform rival Anthropic’s Claude Fable 5 on some tasks.
The models were subject to a staggered launch at the request of the US government, which has taken an increasingly restrictive approach to sharing advanced home-grown AI models over concerns around cyber safety and technological dominance.
CEO Sam Altman told CNBC that the flagship version of the model – GPT-5.6 Sol – is 54pc more token-efficient on agentic coding tasks, performing “as good or better” when compared to competing models on the market.
According to the company, GPT-5.6 Sol scored 53.6 on an adaptive reasoning evaluation, beating Fable 5 by around 13 points. At medium reasoning, it beat Fable by around 11 points at roughly one-quarter of the estimated cost, OpenAI said.
