Odaily News: OpenAI has announced the launch of GPT-6.1 Sol, which the company says delivers performance "close" to GPT-6 Astra, with standard API pricing at roughly one-fifth of Astra's.

Sol is currently available for ChatGPT Work, Codex, and the API, while general Chat conversations are not yet supported. Its context window is approximately 1.05 million tokens. OpenAI also stated that this week, API prices for GPT-6 Sol and GPT-6 Luna will be uniformly reduced by about 50%. Tibo explained that as model efficiency improves, fewer credits can theoretically accomplish a similar amount of work, and promised that the previous 5-hour limit will not be reintroduced. However, there is currently no empirical data comparing the old and new plans. Regarding subscription benefits, some users claim that GPT-6 Astra credits will be halved, while others suggest that given the price cuts for Sol and Luna, the actual change when using these two models does not amount to a reduction in credits.

Previously, after Anthropic released Claude Sonnet 5.5, users began comparing usage allowances and pricing advantages across different plans. Some users estimated that with the $200 plan, the credits available when using Sonnet 5.5 could reach several times that of the corresponding GPT plan.

OpenAI is still advancing products based on GPT-6 Astra, including a continuously running agent feature called "dots," where each agent has an independent cloud computer and can handle tasks around the clock. This feature is being offered to Pro, Business Premium, and Enterprise users.

Odaily reports: Bitget stated on X platform that an investigation by Google Cloud's Mandiant into Bitget's September 24 security incident found that attackers gained unauthorized access to certain third-party security devices, then laterally moved into Bitget's exchange wallet environment and obtained access to both warm and hot wallets. The investigation findings are consistent with the attack path previously disclosed by Bitget.

Odaily News — SlowMist security team has disclosed preliminary investigation findings on the September 25 theft of assets from Bitget's hot wallet. The investigation found that the attack involved certain third-party security products and wallet application hosts, with a zero-day vulnerability present in one of the third-party products. The attacker also gained unauthorized access to a third-party product management platform by impersonating an internal employee.

SlowMist stated that the team has obtained the custom withdrawal tool used by the attacker to interact with the wallet system's withdrawal logic. On-chain attack activity began at 2:31 on September 25, lasted approximately 2 hours and 52 minutes, and involved multiple blockchains. The attacker subsequently attempted to tamper with withdrawal records and trigger additional BTC withdrawals. The team is still investigating how the attacker moved laterally between the affected systems.

Odaily Report: CZ posted a meme on the X platform this morning with the caption "Soon....", and also forwarded a bullish tweet about BNB Chain, which stated that tokenized U.S. stock assets have already been put on-chain, and that BNB Chain is one of the major participants, with advantages including low Gas fees, roughly 0.45-second block times, over 2 million daily active users, and approximately 17 million daily transactions, based on which it argued that BNB Chain will become a market focus in 2026.

In response, well-known trader Bonk Guy said CZ is very likely hinting at a potentially explosive "BNB szn" rally, and also said that users should not claim later, when the market starts heating up, that they had not been given a heads-up, adding that "the hint has already been given, you just did not notice it."

MIM is effectively backed at less than $0.04 per token, with over 95% lacking collateral support. As a CDP stablecoin, MIM constitutes protocol liability with priority over the governance token SPELL; until MIM liabilities are fully repaid, SPELL holds no accounting value.
