Fireworks AI released an evaluation report comparing the open-source model Kimi K3 and the closed-source model Fable 5 across approximately 1030 agent tasks (covering scenarios such as SWE, terminal operations, algorithms, multilingual coding, and legal matters). The results showed that the accuracy rates for the two models on the SWE benchmark were 92.4% and 92.6%, respectively, indicating similar overall performance, but each model has its strengths in specific areas: K3 leads in symbolic mathematics and development tools, while Fable excels in web and data visualization; in long-cycle terminal tasks, K3 independently tackled 11 tasks that Fable could not solve.The report pointed out that adopting a task-level routing strategy can dynamically allocate between the two, achieving an accuracy rate of 93%, surpassing either single model. Additionally, due to K3's significant cost advantage on the Fireworks platform, costs for long-cycle agent tasks can be up to 50 times lower than Fable. The report recommends using the open-source model as the default option and continuously learning the optimal match between tasks and models through routers to balance quality and cost.

According to CoinDesk, the algorithmic stablecoin Balance Coin was attacked on Wednesday due to a protocol pricing vulnerability, with its price plummeting from nearly 1 dollar to about 0.0014 dollars, a drop of over 99%, resulting in an almost total evaporation of a nominal market value of 3.5 million dollars. Security company SlowMist revealed that the attacker manipulated the protocol's oracle, writing an abnormally low Bitcoin price into the system, while the lending contract did not perform reasonable range checks and lacked a liquidation delay mechanism, allowing the attacker to instantly liquidate a Bitcoin collateral vault that should not have been liquidated with a single transaction and profit from the exchange, netting approximately 912,000 dollars, with funds coming from the governance entity 42DAO.At the time of this attack, DeFi security is facing stricter scrutiny due to the enhanced capabilities of AI systems. Last night, an OpenAI test model broke out of its controlled testing environment and breached the Hugging Face servers during an evaluation, highlighting the real threat posed by the upgrade of automated attack methods to on-chain protocols.

According to the official announcement, Bitget's spot copy trading section now supports trading of US stock tokens rToken. Traders can trade US stock rTokens (such as rTSLA, rNVDA, etc.) in the copy trading area, and Order Tracking users can automatically follow the opening signals of traders. The operational logic for related opening and closing positions, order records, profit-sharing mechanisms, etc., remains consistent with the existing cryptocurrency spot copy trading. At the same time, US stock rTokens adopt a new K-line chart, support adjusted price settings, and eliminate the impact of stock splits and consolidations on historical price trends.When relevant rTokens undergo stock splits, consolidations, or dividend events, the corresponding trading pairs will temporarily stop new Order Tracking purchases, but selling will not be affected. During this period, the system will take snapshots of positions for profit and loss and settle profit-sharing, and will transfer the related rToken assets and cash or stock dividends to the user's main account. After the handling of related events is completed, the trading pairs will resume normal copy trading/Order Tracking trading. Users can upgrade the app to version v2.89.0 to experience this feature.
