Google open-sourced Harness², GLM-5 score improved by 11.5 points

Google Research's open-source AI toolchain self-improvement framework Harness² allows AI Agents to automatically modify system prompts, memories, skills, tool rules, as well as scripts and plugins without retraining the model. The project is licensed under the Apache 2.0 license and supports OpenCode and Codex. Its core mechanism enables the Agent to learn through trial and error, proposing several improvement plans when encountering new tasks, which are then executed and compared by different versions of the Agent, ultimately combining to form a more suitable solution.Even without a standard answer, the system can seek improvement directions based on the actual execution process. After the task is completed, the system remembers which modifications were effective and the reasons for them, for reference in similar future problems. Google tested using GLM-5 and Gemini 3.5 Flash. On WorkBuddy-Bench, GLM-5 paired with OpenCode improved its average score from 64.2 to 75.7 after just one round of optimization, surpassing the unoptimized Gemini 3.5 Flash's score of 72.4.In legal task testing, the pass rate for GLM-5's partial scoring criteria increased from 59.6% to 71.4%. In the experiment, Claude Opus 4.8 was defaulted to propose and implement improvements, while GLM-5 and Gemini were primarily responsible for executing tasks, not relying entirely on their own evolution. Domestic developer Joseph Zhou demonstrated an experiment where Harness² integrated with Jev 1.14, claiming that the performance on visual tasks continuously improved.

Bitwise Chief Investment Officer Matt Hougan stated that the third quarter may be one of the best-performing quarters in cryptocurrency history, with a significant price rebound and continuous growth in the on-chain market, pointing to the beginning of a "crypto spring." The quarterly market review released by Bitwise shows that its large-cap crypto index rose 46.4% in Q3, while the U.S. spot Bitcoin ETF recorded $6 billion in inflows during the same period, bringing the year-to-date net inflow back into positive territory.The growth is not limited to coin prices. The value of tokenized stocks increased by 65.5% to nearly $3.2 billion, and the open interest in decentralized perpetual contracts reached a new high of nearly $26 billion, with the proportion linked to stocks, commodities, foreign exchange, and pre-IPO shares continuously rising. Bitcoin rose 42.3% in Q3, while Ethereum and Solana increased by 69.1% and 59.2%, respectively. All ten constituent assets of the large-cap index recorded double-digit quarterly gains, with Chainlink leading at a 97.6% increase.The rebound did not cover all sectors of the industry. Bitcoin mining companies Riot Platforms and Hut 8 saw their stock prices drop by 26.4% and 25.4% in Q3, respectively, while Galaxy Digital fell by 16.8%; the number of publicly traded companies holding Bitcoin decreased by nearly 6% to 173, and the number of companies holding Ethereum dropped from 40 to 35.
