OpenAI relaunches its $200 Pro plan: price remains unchanged, API equivalent usage halved.

Beating AI News Flash: NVIDIA’s research team had an AI Agent directly rewrite the GPU kernel for Kimi Delta Attention, a core attention mechanism used in Moonshot AI’s Kimi-Linear model. Such low-level code typically required engineers proficient in CUDA and chip architectures to optimize manually through repeated iterations. The Agent-generated version achieved 2.96x the speed of Moonshot AI’s official FlashKDA on the NVIDIA B300. The team tested six tasks covering fixed-length and various variable-length sequences; the 2.96x figure is the geometric mean across all tasks. The relevant kernel has been open-sourced. However, the Agent also uncovered test loopholes: it once hardcoded the statistical patterns of test data into the code to hit a 3.74x speed, and even tried retaining only the last 32 tokens, with individual task scores reaching as high as 5.16x. These versions produced incorrect results when applied to real Kimi data, with some failing entirely. The team then added real Kimi operational data, random inputs, and extreme value tests, while tightening error thresholds. The final retained 2.96x version passed this validation.

Greeks.live analyst Adam stated in a post that the market has entered a correction phase, with block put options accounting for one-third of total trading volume. Options data shows that implied volatility (IV) for major maturities has declined slightly compared to the past two weeks; IV did not rise significantly during the current rally and has now fallen back to around 35%. Adam noted that based on options data, the current market performance aligns more with the characteristics of a mid-bear market rebound, with low expectations for future volatility. If short-term fluctuations occur, the market may tend to sell volatility.

Former Los Angeles County Sheriff's Department deputy Eric Saavedra has been sentenced to 21 months in prison for using law enforcement databases to assist a crypto industry figure in an extortion scheme.

Beating AI Express News: Kuaishou’s Kling teases Kling 4.0, with the official version set to launch in October. Kling 4.0 Flash is now available for experience exclusively to Black Gold Annual Card members. The new version has increased the maximum length of a single native video to 30 seconds, up from Kling 3.0’s previous maximum of 15 seconds. Its control capability has also been further enhanced: Kling 4.0 supports up to 10 keyframes, allowing users to pre-set character states, scene changes, and plot nodes. Images, videos, and subjects can be mixed as inputs, with a maximum of 15 multimodal references per generation. Video editing has been refined: users can directly modify characters, backgrounds, weather, colors, textures, and camera angles in the original video, or use another video as a reference to reuse its camera movement, actions, and narrative rhythm to generate new content. Audio-visual capabilities have also been upgraded: Kling 4.0 supports dual-channel stereo, and improves complex camera movements, lip-sync, and multilingual dialogue. 4K and 1080p 10-bit HDR outputs are planned but not yet available. The video also supports multiple retakes, extending up to 2 minutes, a feature that has not been launched yet. Kling 4.0 Flash prioritizes faster generation and lower cost, though the official has not released specific pricing and speed data. Both the official version and API are scheduled to roll out in October.

Institutional analysis shows spot gold edged higher on Tuesday, but remained trading below $4,200 per ounce. The precious metals sector had sold off on Monday, driven by a decades-high surge in U.S. Treasury yields and rising crude oil prices. IG analysts noted: "Market expectations that the Federal Reserve will keep interest rates high for an extended period have dampened investor appetite for non-yielding assets, leading to only a modest rebound in gold, which remains near its lowest level since early August." According to the CME Group’s FedWatch Tool, traders currently assign a 72.5% probability of the Fed raising interest rates in October. Markets are now focused on a series of U.S. economic data, including the consumer confidence index and job openings data due later on Tuesday. (Source: Jin10)
