Beating AI News (Insight): AI 3D firm VAST (Sanqi Wanwu) has closed its Series B and B+ funding rounds, raising a combined ~3 billion yuan, led by Matrix Partners China. Strategic investors including Perfect World, BlueFocus, Cambricon Technologies, and 37 Interactive Entertainment participated, while existing shareholders such as DC Capital, Spring Capital, and 4399 made follow-on investments. No specific valuation was disclosed for this round. The pace of its financing is even more striking than the amount raised: VAST secured a $50 million Series A round as recently as March, followed by nearly $200 million in Series A+ and A++ rounds in June, and over 1 billion yuan in Series A3 in July. Adding up the disclosed funding amounts, its total financing has reached nearly 6 billion yuan. AI 3D has indeed emerged as a sector heavily backed by capital lately. Its direct competitor Meshy just completed a nearly $400 million Series B round in July, hitting a $1.5 billion valuation.

Solana-based automated market maker (AMM) Aquifer was hacked on August 31, incurring losses of approximately $2.5 million. The protocol later issued an on-chain "white hat" offer, demanding the attacker return at least 80% of the stolen funds to designated Solana and Ethereum recovery addresses by 22:00 on September 3, with the attacker permitted to retain up to 20% as a bounty. The project team has committed to not filing civil lawsuits against the attacker if the terms are met.

Beating AI News Flash: Amazon Bedrock has started returning a 404 "Model not found" error for the model ID suspected to be Fable 5.1 (the model name specified in the API).

Per AWS’s error code definitions, this indicates Fable 5.1 has been integrated into Bedrock’s backend, and its launch preparations are underway.

Today, Robinhood Chain leads the meme token concept tied to meme stock short squeezes. Per GMGN market data, after the meme token BONER paired with U.S. stock HIMS surged past $70 million, the meme stock token Rabbit, issued via the o1 platform, hit a $15 million market cap in just 9 hours post-launch, currently trading at $15.56 million. Rabbit is paired with U.S. stock WYFI. Public information reveals the origin of the meme token: CERN (European Organization for Nuclear Research) recently developed an open-source, fiber-optic-based high-precision time synchronization protocol named Rabbit, which delivers sub-nanosecond accuracy, has been incorporated into IEEE standards, and is used in quantum experiments and emerging quantum network infrastructure. WYFI is an AI infrastructure company listed in 2025, specializing in data centers and HPC cloud services, and has potential to benefit from this technology. As of press time, per BIT (bit.com) market data, WYFI is down 0.74% in after-hours trading. It should be noted that the token’s short-term rally is closely linked to hype from top KOL "bonk guy" on the FOMO platform, who holds positions in the token and promotes it. BlockBeats reminds users that related tokens have high price volatility, and investors should exercise caution.

On-chain researcher Rarma’s analysis reveals that Injective halted block production for approximately 3 hours and 42 minutes on August 31. The block height recovered from 181,027,006 to 181,027,007, with no rollback occurring during the outage. QuickNode’s status records also confirm that Injective’s mainnet experienced a full-network block stagnation that day, prompting the deployment of an emergency patch. Attackers are suspected of repeatedly exploiting Injective’s insurance fund and permissionless binary options market creation mechanism, executing a total of 299 related operations, and ultimately funneling roughly 1,979.8 ETH (valued at around $4.88 million) in proceeds to a single address.
