Anthropic upgrades Claude's voice mode. Paid users can now choose Opus, Sonnet, and Haiku, no longer limited to the faster but less capable Haiku.Users can switch models during conversations and can also switch to text at any time. Claude defaults to the model selected in the last text chat and calls the fastest version in that series. The voice mode can also access Gmail, Google Calendar, Google Docs, and Slack. Users can have Claude check emails, change schedules, or draft replies, and will request authorization before executing.The new version is now available for testing on mobile, desktop, and web. Free users can only use Haiku and one connection tool. Voice now supports multiple languages including English, Japanese, and Korean, but does not include Chinese at this time. This upgrade mainly enhances model reasoning and tool invocation capabilities. Anthropic has not changed the voice model, so the naturalness of speech and interruption experience may not show significant changes.

Libbitcoin developer @evoskuil stated that the latest version of Libbitcoin Server can complete the initial block download of a Bitcoin full node in 55 minutes and perform full verification. This speed improvement comes from a new GPU-based signature verification system that runs in parallel with conventional script verification, rather than as a separate step.The software does not pause execution to verify each ECDSA and Schnorr signature; instead, it captures signature checks, batches them, and processes them via GPU while the remaining verification continues. @evoskuil indicated that this method achieves about a 99.5% signature capture rate without blocking verification, thus eliminating the need for a second verification. If a batch signature check fails, the software traces it back to the corresponding block and marks that block as invalid. He also mentioned that this design can batch process an almost arbitrary number of signatures, keeping the GPU ahead of the remaining verification process and significantly shortening the full node synchronization time.

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 Digital Asset, officials from the Korean National Tax Service have proposed legislative suggestions, believing it is necessary to amend the Criminal Procedure Act to allow for the seizure of virtual assets held by individuals. Individual ownership of digital assets refers to the situation where the private key is directly held by the individual, without the need to entrust a third party for custody or disposal.In June of this year, four individuals, including Zhang Xiyuan, the head of the National Tax Service investigation team, published a paper titled "Limitations and Legislative Review of Self-Protecting Virtual Asset Seizure Execution" in the journal "Criminal Policy Research" of the Korean Institute of Criminology and Justice. The paper explains that separate regulations must be established for the requirements and procedures for transferring to a public wallet or obtaining control. The paper first points out that when a suspect or owner holds access means such as a private key, the search warrant must clearly specify the following: the type and quantity of digital assets to be seized; verified addresses; addresses to be transferred; methods of transfer; and storage methods after the transfer. Furthermore, due to the risks of theft associated with transferring assets to wallets managed by a single entity, the paper proposes a method for transferring to a joint address managed by both the court and investigative agencies.

According to the Korea Herald, South Korea's financial regulatory agency has issued an investigation report to Upbit's operator Dunamu, initiating sanction procedures.

Subsequently, the final sanction measures will be determined by resolutions from the Sanction Review Committee, the Securities and Futures Commission, and the Financial Services Commission.
