Currently, both the B.AI API and Web Chat have been synchronized and opened, allowing developers and users to directly access this new generation Sonnet model that balances speed, cost, and long context capabilities.

Anthropic released Claude Sonnet 5.5 this Monday, as an upgraded version of Sonnet 5 launched in June this year. The official statement claims that this mid-range model operates over 30% faster than the previous generation, excelling in clearly defined daily tasks, fixing defects, and creating documents, slides, and spreadsheets, while also possessing sharp design capabilities. Its pricing remains at $2 per million input tokens and $10 per million output tokens, which is half of Opus 5.5, and the token consumption per task is nearly one-third less than Sonnet 5.In the Terminal-Bench 4 test, Sonnet 5.5 scored 70.6%, higher than Opus 5.5's 66.4%, and Sonnet 5's score was only 10.3%.

Two ChatGPT users from California filed a proposed class action lawsuit against OpenAI in the United States District Court for the Northern District of California this month, accusing the company of failing to adequately inform users that their real conversations were being handed over to external contractors for processing. The lawsuit was served to OpenAI on September 2, focusing on its internal initiative Project Lily. According to the complaint, "AI data reviewers" and "chatbot evaluators" recruited through a third-party staffing company read real ChatGPT prompts and complete conversations, summarize user intent, and score and comment on responses from four models on a scale of 1 to 7.This process is known in the industry as reinforcement learning from human feedback (RLHF), which is a fundamental method for enhancing chatbot capabilities. The complaint states that users were never explicitly informed that a person, rather than a machine, might be reading their conversations. OpenAI filters conversations through an automated system before human review, but the complaint alleges that the filters cannot intercept all content, and personal details sometimes still reach contractors. 404 Media first reported on the project on September 14 and found that the reviewers' dashboard included "user memory summaries," which could expose users' approximate locations, occupations, or private life information, even though usernames had been removed.OpenAI stated that such reviews aim to reduce two behaviors: chatbots behaving too much like humans and overly catering to users, referred to by researchers as "flattery." The complaint raises eight legal claims, including violations of California's Unfair Competition Law, Consumer Privacy Act, and common law claims for intrusion into private affairs, with the plaintiffs seeking damages, restitution of unjust enrichment, and punitive damages.

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.

According to The Block, the U.S. Supreme Court ruled 6 to 3 in favor of Trump's right to replace the leaders of several independent federal agencies, including the FTC, excluding the Federal Reserve, strengthening the president's control over personnel in regulatory agencies.As this ruling comes out, the SEC and CFTC are advancing a new round of regulatory rules for crypto assets, including rule revisions, exemptions, and the allocation of responsibilities regarding digital assets. Currently, the SEC is led by three Republican commissioners, while the CFTC has only its chairman, Michael Selig, in office.Former CFTC officials and industry insiders have stated that the reduction in the number of commissioners may weaken internal negotiations and the robustness of rules, and may also make rules under a single commissioner more susceptible to being rewritten or abolished in future administrations. However, as long as they comply with their respective authorizing statutes and the Administrative Procedure Act, the relevant rules still have legal effect.
