Increase and Improvements in Agentive AI Models: Updates on GPT-5.6 and Proposals for the Open Ecosystem
The use of agentive products based on Codex and ChatGPT increased 2.5 times in the last week. GPT-5.6 offers greater efficiency and lower cost, while the importance of open-source platforms in AI is highlighted.

What Happened
Sam Altman, CEO of OpenAI, announced a significant increase in the use of their agentive products based on Codex and ChatGPT, with a 2.5-fold increase in the last week. He also highlighted improvements in the GPT-5.6 "sol" model, which is approximately half the cost and up to twice as efficient in tokens as the previous "fable" model for performing similar tasks. This represents a considerable advance in the economic efficiency of foundational models.
Simultaneously, Altman emphasized the importance of supporting open-source ecosystems for the development and integration of AI models, pointing to this as a strategic advantage for innovation. He also expressed interest in a proposal made by Demis Hassabis, founder of DeepMind, although without detailing its content.
Why It Matters
The increase in the use of AI agents and the technical improvement of models like GPT-5.6 indicate the growing maturity and adoption of foundational models for practical applications in industry and end consumers. Cost reduction and efficiency improvements are key factors for companies to integrate AI into their operations and products, expanding accessibility.
The emphasis on open-source platforms points to a trend where transparency, collaboration, and technical flexibility will be critical factors for the success and sustainable evolution of the AI ecosystem. This, in turn, may foster more dynamic competition and greater technological diversity, aspects relevant to the regulation and responsible adoption of AI.
What Remains to Be Confirmed
Although interesting improvements and proposals related to foundational models and AI agents are mentioned, exhaustive technical details or information about the concrete impacts of Demis Hassabis's proposal referenced by Altman are not available. Neither are detailed metrics or examples illustrating the specific applications enabling the usage increase or associated case studies.
