According to official news, OpenAI has officially launched the preview version of the next-generation GPT-5.6 series models, including the flagship model Sol, the balanced model Terra, and the fast low-cost model Luna. GPT-5.6 introduces a brand new maximum reasoning effort and features a super strong mode that accelerates complex tasks through sub-agents.The flagship model Sol introduces the Ultra mode, which combines maximum reasoning intensity with sub-agent collaboration. In the Terminal-Bench 2.1 command line workflow test, Sol achieved a score of 88.8%, which increased to 91.9% in Ultra mode, surpassing GPT-5.5's 83.4% and Claude Fable 5's 88.0%. The mid-range model Terra performs close to GPT-5.5 while being priced at half, and the lightest model Luna is designed specifically for everyday automation tasks. Sol is priced at $5 per million input tokens and $30 for output, and it supports reducing secondary call costs by utilizing prompt caching.In terms of security, the security assessment confirmed that Sol did not exceed the critical thresholds of the Preparedness Framework cybersecurity. OpenAI has invested over 700,000 A100 equivalent GPU hours in automated red team exercises, equipping the entire series of models with a defense stack that includes rejection mechanisms, real-time abuse classifiers, and account-level audits. Although the current limited release follows the U.S. government's security framework, OpenAI emphasizes that it does not want a government-led access mechanism to become the long-term default model, as it would limit defenders' access to cutting-edge tools.

According to official news, the scalable blockchain network AO based on Arweave has announced the launch of the "Network Availability Staking Alpha (NASA)" testing program, which is a key step in its AO ecosystem aimed at enhancing the availability and reliability of decentralized data networks through a staking mechanism. The program is currently in the Alpha stage, and users can participate in network availability verification and earn rewards by providing data services for Arweave gateways and staking AO tokens.In the first pilot phase, AO introduces the "availability staking" mechanism, requiring node operators to stake 25 AO to participate in the network and compete for the speed and stability of responding to user requests. The system will allocate rewards from a monthly reward pool of 1000 AO based on the performance of nodes in data services. This mechanism relies on the next-generation HyperBEAM architecture, enabling higher levels of verifiability and trustlessness for gateway and routing services while significantly reducing operational costs.The project team stated that NASA aims to establish a stronger decentralized economic model for the entire permanent network infrastructure, paving the way for future expansion into areas such as computing scheduling, data indexing, and network services. Although the current reward scale is small and still in the testing phase, the program is seen as an important starting point for the AO-Core economic system and will gradually expand to more network infrastructure services in the future.
