OpenAI has launched the next generation GPT-5.6 series models, currently available only to trusted partners using Codex and the API

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.

The cryptocurrency market is generally down, with the NFT sector dropping nearly 4%, while only the SocialFi sector remains relatively strong

According to SoSoValue data, the overall trend of the cryptocurrency market is declining, with the NFT sector down 3.79% in the last 24 hours. Within the sector, Pudgy Penguins (PENGU) decreased by 2.96%, and Audiera (BEAT) fell by 6.29%. Meanwhile, Bitcoin (BTC) dropped by 1.06%, falling below $64,000; Ethereum (ETH) decreased by 1.34%, fluctuating around $1,700.Only the SocialFi sector remained relatively strong, being the only sector to rise today, up 1.23% in the last 24 hours, with Gram (GRAM), renamed from Toncoin (TON), increasing by 2.13%.In other sectors, the DeFi sector fell by 0.47% in the last 24 hours, but DeXe (DEXE) surged by 59.33%; the CeFi sector declined by 0.94%, where OKB (OKB) rose by 2.98% due to various factors including the establishment of a joint venture with Intercontinental Exchange (ICE), briefly surpassing $83 during trading; the Layer1 sector decreased by 1.51%, with TRON (TRX) rising by 1.77% during trading; the Layer2 sector fell by 1.51%, while Celestia (TIA) increased by 5.40% against the trend; the Meme sector dropped by 1.55%, but BUILDon (B) rose by 6.27%; the PayFi sector decreased by 2.04%, while Telcoin (TEL) increased by 8.06%.The cryptocurrency sector index reflecting the historical market performance shows that the ssiAI, ssiDePIN, and ssiRWA indices fell by 7.86%, 5.26%, and 2.97%, respectively.

Secret Network lost 4.67 million dollars due to a cross-chain vulnerability, and the attack went undetected for seven days

The blockchain research organization Common Prefix disclosed that on June 10, hackers exploited a vulnerability in the Secret Network and Axelar cross-chain bridge contract to forge deposits and mint uncollateralized tokens, subsequently cashing out approximately $4.67 million.The attack went undetected for seven days until a normal cross-chain transfer failed due to insufficient funds in the escrow account on June 17, revealing the anomaly. The root of the vulnerability lies in the fact that when the contract changed from an escrow model to a minting model, it deleted two key functions responsible for verifying the source of transfers, and it had never undergone an external audit since its deployment in early 2023. Secret Network pointed out that the Axelar bridging infrastructure failed to trigger any effective anomaly monitoring or emergency pause mechanism before the assets were stolen on a large scale.The stolen funds were routed through Osmosis to Ethereum and exchanged for ETH on CoW Protocol, then dispersed into exchanges such as KuCoin, ChangeNow, and HitBTC. Currently, approximately $672,000 remains in the attackers' Axelar wallet. Secret Network has requested Axelar to freeze that address, but the request was denied. Axelar emphasized that its core protocol was never affected, and the exploited contract was not developed or maintained by Axelar. Currently, Axelar has disabled the related cross-chain connections and stated that it is coordinating follow-up actions with exchanges and law enforcement agencies.

Axelar responds to security incident: Axelar and IBC are unaffected, the vulnerability originates from a third-party token contract's "infinite minting" issue

The cross-chain protocol Axelar Network released a statement regarding the recent security incident related to Secret Network, stating that there is a misunderstanding within the community about the event. Both Axelar and the Inter-Blockchain Communication Protocol (IBC) were not attacked or compromised. The affected token smart contracts were neither developed, deployed, nor maintained by Axelar, and Axelar's firewall mechanism also prevented the impact from spreading to other chains.It is reported that the exploited contract is a forked version based on CW20-ICS20, but the developers removed two core security checks, resulting in an "infinite minting" vulnerability. By deleting the verification mechanisms originally used to prevent such issues, this fork altered the original trust model of the contract and did not undergo a new security audit.Axelar Network explained that anyone can deploy contracts for cross-chain asset wrapping through IBC, and similar contracts have also been used to wrap tokens from other chains into Secret Network. However, the Secret side fork version in this incident has vulnerabilities due to the removal of key security checks. This incident is not a unique logical flaw, nor is it an issue with the IBC protocol itself, but rather a security risk introduced by modifications to third-party contracts.
