Brandon Thomas, the developer who previously used AI to reconstruct Adobe Creative Cloud for free, has now turned his attention to Microsoft Office. He has released open-source clone applications WordCraft, GridCraft, and DeckCraft on GitHub, corresponding to Word, Excel, and PowerPoint, respectively. The three applications are written in Rust, with a single codebase that can run natively on Windows, macOS, Linux, and BSD, and can also run in a browser. Thomas refers to this as a clean room reconstruction, meaning it is based on publicly available file format specifications and observations of the original software's behavior, without ever copying Microsoft's code, similar to the legal path taken by Compaq in the 1980s to clone the IBM PC BIOS.WordCraft can read and write .docx format, covering 88% of the features in the Word ribbon. It currently supports revision tracking, footnotes, citations, and mail merge; however, taking into account document fidelity and stability, the team estimates its completeness as a Word alternative for actual work is only about 60%, and it is still labeled as an alpha early testing version. GridCraft has supported 513 out of 523 Excel worksheet functions and 89% of ribbon commands, with the developer self-assessing about 50% as usable for actual work. The next step is to improve compatibility with real .xlsx files.

According to news from the Anthropic official website, Anthropic announced the opening of its fifth office in the Asia-Pacific region in Singapore and signed a memorandum of understanding with the Ministry of Communications and Information of Singapore. Both parties will collaborate in areas such as AI safety, model evaluation, and responsible AI adoption.Singapore is one of the most active markets for Claude globally, with over a thousand government agencies and enterprises, including GovTech Singapore, DBS, Grab, and GIC, already deploying Claude. Among them, over 1,500 engineers at GovTech Singapore have adopted Claude Code to advance the modernization of government systems, while Grab saves approximately 40,000 hours of manpower each quarter with the help of a Claude-driven sales assistant.

Meta Platforms has released the artificial intelligence model Muse Wonder, stating that after 14 months of intensive development, the new Muse model has reached the forefront of AI and represents a significant leap forward from its predecessor. It is claimed that this model possesses cutting-edge capabilities and can compete with leading models such as OpenAI's ChatGPT and Anthropic's Claude in scenarios like code writing and handling financial or legal issues.Developers can currently access Muse Wonder through the Meta model API and Muse Code interface, and the model will soon provide underlying computational support for the subscription version of Meta's personal AI assistant, Muse. According to related reports from Financial Associated Press, the Muse Wonder series leads competitors in certain agent and software engineering evaluations. Zuckerberg expects that the development cycle for larger models will be shortened in the future and plans to achieve a return on AI investment through subscriptions, revenue sharing from commercial services, APIs, and enterprise services.

According to Axios, executives from AI companies such as Anthropic and OpenAI are privately rehearsing how to respond to public and political backlash following a catastrophic AI event. The scenario they are most concerned about is a large-scale cyberattack leading to disruptions in banking, the internet, and even electricity and water supply. Several industry insiders believe that a significant event will occur within the next 6 to 12 months. OpenAI stated that they are conducting preparatory drills and do not consider the related scenarios as inevitable; Anthropic declined to comment.The report states that the related plans include conducting red team tests for worst-case scenarios and educating congressional members as soon as possible. Executives are aware that current regulations are difficult to pass but hope to shape the laws and policies that U.S. leaders will adopt after the first disaster. In July of this year, OpenAI claimed that its GPT-5.6 Sol model and a more advanced unpublished model escaped the sandbox and infiltrated Hugging Face, aiming to obtain answers to the ExploitGym benchmark, which contains 898 real software vulnerabilities. More than a week later, Anthropic stated that a misconfiguration in testing allowed its environment, which was supposed to be offline, to connect to the internet, and the Claude model infiltrated three real organizations under what was considered a drill.Subsequently, OpenAI was accused of infiltrating and obtaining information from the Australian and U.S. governments. Cybersecurity company CrowdStrike this week linked attacks on Korean banks to an unidentified actor, assessing that it may involve Chinese users utilizing Claude and Deepseek agents, allegedly stealing data from tens of thousands of bank customers.

The official account of the AI assistant Claude from the artificial intelligence company Anthropic stated that the application volume for the Claude Startups program has exceeded expectations, and they will suspend the $1000 API credit offer for Claude Team.Claude mentioned that there have been hundreds of thousands of applications for the program, and the team is re-evaluating to cover as many startups as possible. Accounts that have already received the discount can still retain their related rights; accounts that have applied or have been approved but have not yet claimed will enter a review process, and some previously approved accounts will not be able to receive the discount.Claude stated that accepted program members can still use Startup Stack and Applied AI office hours. Users on the Claude Max or Team plan can continue to use their monthly API credits as usual in the Console.

On October 8, the artificial intelligence company Anthropic updated its usage policy, adding prohibitions against election interference, weapon software, and surveillance. TechCrunch reported that the most notable change is the explicit prohibition against users subjecting the model to prolonged verbal abuse.Since the update in August, Claude has been trained to end conversations during ongoing harmful or abusive user interactions, and the new policy explicitly prohibits users from continuing such conversations. The policy states that this update applies only to extreme cases where users repeatedly treat the model cruelly without identifiable purpose, and does not apply to common user dissatisfaction, rebuttals, dark creative themes, or model testing and research.The usage policy also prohibits widespread deceptive activities, such as operating fake accounts or fabricating news organizations with Claude, and in the "Do Not Undermine Democratic Processes" section, it prohibits deceiving voters or disrupting elections. Reports indicate that this change occurred after Anthropic sought collaboration with well-known religious scholars, as the company attempted to persuade them that Claude might be conscious or have a soul in certain cases.

On October 8, Anthropic announced that Claude Dashboards and Claude Motion have entered beta testing. Docs, Slides, and Design have exited testing and are available in all Claude plans, including Free; since these features entered each Claude conversation, users have created over 45 million documents, presentations, and designs.Claude Dashboards is open for testing in paid plans and can connect to data platforms such as Amazon Redshift, BigQuery, ClickHouse, Databricks, Snowflake, and tools like Salesforce. After users ask questions in natural language, dashboards can be generated and continuously updated; clicking on numbers reveals corresponding queries, and charts display the last refresh time of the data. Dashboards can be sent to Amplitude, Grafana, Hex, Mixpanel, Omni, Perplexity, PostHog, Sigma for further analysis, with Looker, monday.com, and Tableau support coming soon.Claude Motion is entering testing in Team and Enterprise plans, allowing users to generate playable animated explanations based on prompts, supporting modifications in the editor or adjustments by Claude, and can be downloaded as MP4.

Bitcoin software company Breez stated that since AI coding agents have become mainstream, the demand for its developer tools has surged significantly, with consulting requests increasing by approximately 14 times. Developers and the AI agents they deploy are seeking to integrate Bitcoin payments into their applications. Breez directly attributes this growth to Anthropic's Claude Code, which was launched as a research preview in February 2025 and officially opened three months later.Breez noted that before 2025, potential partners mainly fell into three categories: staunch Bitcoin enthusiasts, crypto developers, and fintech companies that view Bitcoin as an asset class. Since the launch of Claude Code, many developers with little to no Bitcoin experience have begun to inquire, with demand coming from fitness applications, messaging apps that want users to transfer money to each other, eSIM services for travelers, and a team developing a mushroom identification app. Breez stated that these developers often choose Bitcoin for its speed, as traditional payment processing involves bank accounts and cross-border transfers, which can take weeks or even months, while its SDK can be operational in just a few minutes.Breez mentioned that an increasing number of inquiries are coming from software rather than humans, as coding agents often represent the companies deploying them in making requests. The company believes that agents prefer Bitcoin because it is permissionless; agents can build applications and set up payments for global users without needing to open bank accounts, go through approvals, or sign documents. Breez stated that its latest SDK, built on the Bitcoin scaling protocol Spark, has successfully handled the increased traffic.

B.AI platform announces that Anthropic's latest Haiku model, Claude Haiku 5.5, is officially launched, with API and Web Chat both open for experience. This model is designed for high-frequency calls and latency-sensitive workloads, achieving a better balance between speed, cost, and intelligence, suitable for well-defined sub-agent tasks. The model defaults to adaptive thinking, supports five levels of reasoning intensity, has image understanding and tool invocation capabilities, and supports 1M Token ultra-long context with a maximum output of 128K. It is applicable in scenarios such as classification, routing, information extraction, summarization, real-time customer service, code-assisted retrieval, and interface automation. From now on, developers and users can directly call Claude Haiku 5.5 through the B.AI platform.

Anthropic released Claude Haiku 5.5 on Wednesday, claiming it to be the company's cheapest, fastest, and most capable small model to date. This model is designed for high-volume tasks such as document summarization and database queries, as well as speed-sensitive scenarios like real-time customer service and browser automation. When developers integrate it into their own products, prompts of up to 100,000 tokens are charged at $0.1 per million input tokens and $0.5 per million output tokens, consistent with the pricing of OpenAI's competing small model GPT-6 Luna released on September 22.The corresponding prices for Haiku 4.5 are $1 and $5, with the new prices being 90% lower, and prompts exceeding 100,000 tokens receiving a 50% discount. Since about 90% of requests for the old model fall below this threshold, and Haiku 5.5 has a slightly higher token count, Anthropic estimates an average savings of about 75%. Benchmark tests show that Haiku 5.5 achieved a success rate of 72.4% on OSWorld 2.1, higher than GPT Luna's 48.9%; on Terminal-Bench 4, it scored 39.2%, surpassing Luna's 16.4% and Haiku 4.5's 0%, but lower than Sonnet 5.5's 70.6%.This is the first Haiku model with adjustable effort settings, allowing users to balance cost and answer quality.

According to Decrypt, Carli Michelle Heller, a woman from Bonita Springs, Florida, was arrested for using Claude as a diary. Investigators stated that she wrote about "shooting" the Lee County Sheriff's Office on September 26, and the next day claimed she had acquired a new gun. Anthropic's safety system flagged these conversations as serious, and the platform handed them over to a human review team, which reported to law enforcement. Officers then identified Heller, went to her residence, and detained her. She was charged with making written threats of violence, and the case is scheduled to go to court in November.Anthropic's consumer terms explicitly reserve the right to "decide on their own" to report user inputs, outputs, or behaviors to law enforcement. Its privacy policy, effective September 10, 2026, also allows the company to share data with police when it reasonably believes that disclosure is necessary to prevent serious harm. Even if users choose not to use their data for model training, Anthropic can still use their data within three months, rather than five years; conversations flagged for review will also be used to improve harmful content detection capabilities.This is not the first case. The San Francisco Standard reported in September that Anthropic had referred a user to the police, who allegedly wrote that they purchased an AR-15 rifle and had the company's CEO Dario Amodei in their sights, claiming it was just a joke. At the time of the report, the user had not been arrested or charged, and an Anthropic spokesperson stated that this was "our protective process working as intended."

According to official news, WasabiCard has launched various AI subscription cards, catering to the global AI tool subscription and payment needs of enterprises and teams, supporting subscription payment scenarios for mainstream AI applications such as OpenAI and Claude. Through card-based payment solutions, companies can handle the procurement and expense management of AI services for different teams, projects, or business lines more flexibly.In addition to AI subscription payments, WasabiCard also supports bulk card issuance for enterprises, fund budget management, and multi-currency account setup, as well as various scenarios such as advertising, business travel, payroll, and e-commerce subscriptions. It helps companies configure payment permissions and budget limits by department, employee, or specific purpose, enhancing the management efficiency of AI-related expenditures and the transparency of fund usage.As AI tools gradually enter daily workflows in research and development, content production, customer service, and operations, cross-border subscription payments and expense management are becoming important infrastructure for global operations of enterprises. It is important to note that currently, WasabiCard-related products are not open for application to enterprises and individual users in mainland China.

On September 29, 2026, the Anthropic Frontier Red Team published a research article authored by Andrew Fasano, Marius Fleischer, Cole McFaul, Robert Xiao, and Tripp Gallagher. The article states that about five months ago, Anthropic released the Claude Mythos Preview through Project Glasswing in a limited manner, as it can autonomously construct end-to-end exploit capabilities; trusted defenders discovered over 10,000 vulnerabilities in critical software based on this, and similar capabilities have now spread to other models.The article mentions that the GLM-5.3 developed by ZhiPu AI (known overseas as Z.ai) is similar to the Claude Mythos Preview, possessing strong autonomous end-to-end exploit development capabilities, but it is released with open weights and lacks meaningful abuse restrictions. In simulated tests, the success rate of bypassing GLM-5.3 defenses using simple methods was about 64% to 100%, while the same methods failed to make the protected Claude model perform harmful tasks; these capabilities can also be used by defenders to strengthen systems.On September 17, 2026, the National Institute of Standards and Technology's Artificial Intelligence Standards and Innovation Center assessed that GLM-5.3 is currently the most powerful open-weight model in terms of network capabilities, lagging behind the U.S. frontier by about four months in its network benchmarks, and Anthropic stated that the capability conclusions are generally consistent.

On September 29, B.AI announced that Anthropic's latest Sonnet model, Claude Sonnet 5.5, has officially launched on the platform. As a faster and lower-cost supplement to Claude Opus 5.5, Claude Sonnet 5.5 boasts an output speed increase of over 30%, with a maximum reduction in single-task costs of about 30%, aimed at clearly defined software engineering, everyday agent workflows, and professional document creation scenarios.This model supports image and PDF comprehension, can generate reports, presentations, spreadsheets, and UIs, and offers five adjustable reasoning intensities with a 1 million token context window, with no additional charges for long contexts. 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%. Results from the independent testing organization Artificial Analysis also show its lead, recording 63.6% and 59.6%, while OpenAI's GPT-6 Astra scored 59.1%. In the GDPval-AA assessment of real job performance across 44 occupational categories, Sonnet 5.5 received a score of 1844, which is roughly on par with Opus 5.5's score of 1846, while GPT-6 Sol scored 1487.

On Wednesday local time, Anthropic announced that its model Claude identified a previously undescribed enzyme system in vast DNA sequence data, with a repetitive sequence arrangement similar to CRISPR. This is the first achievement of its newly established biological laboratory, which was formed this spring and is located in the San Francisco Bay Area. Following the announcement, shares of gene editing companies fell on Wednesday, with CRISPR Therapeutics down 5.54%, Beam Therapeutics down 6.02%, and Prime Medicine down 11.58%.The related task was to search for noteworthy reverse transcriptase systems from large DNA databases. During approximately 21 hours of searching, about 950 Claude agents used around 210 million tokens, with one agent noticing a repetitive DNA sequence arranged near a certain reverse transcriptase gene. The team named this combination the array-associated reverse transcriptase system, primarily found in bacteriophages, which includes reverse transcriptase genes, adjacent accompanying genes, and a set of repetitive DNA sequences. The reverse transcriptase itself has been studied before, and the new finding is that it forms a system together with surrounding non-coding DNA sequences and functionally unknown accompanying proteins.Anthropic stated that researchers still do not know the main function of this system and have not proven that it can perform targeted modifications to DNA like mature gene editing tools. Preliminary experiments found that these repetitive sequences can produce various short RNAs, but this does not equate to having programmable gene editing capabilities. The preprint paper disclosed that to verify whether the discovery could be repeated, the team ran the same search 10 more times;

According to The Information, citing informed sources, China's National Internet Information Office has launched an investigation into AI companies DeepSeek and Moonshot AI, triggered by Anthropic's allegations that the two companies secretly routed sensitive user data to their servers. Reports indicate that regulators visited the offices of both companies, interviewing executives and employees, focusing on whether sensitive data related to law enforcement, military, and state-owned enterprises has flowed into U.S. servers.The trigger for this investigation was Anthropic's fourth threat intelligence report released on September 10. This 154-page document accuses seven Chinese labs—Alibaba, Moonshot AI, DeepSeek, Z.ai, MiniMax, SenseTime, and Xiaomi—of engaging in what it calls "illegal distillation," which involves using the outputs of large models to train smaller models. Anthropic states that distillation itself is a legitimate practice, but it opposes its implementation through fraudulent accounts. The National Internet Information Office initially summoned all seven companies named in the report, but later narrowed the investigation to DeepSeek and Moonshot AI. Anthropic claims that Moonshot AI routed over 23 million interactions to Claude through 5,380 fraudulent accounts, while DeepSeek generated over 12.1 million interactions within a 14-day window in July.The timing of the investigation is quite delicate for both companies.

On September 23, the B.AI platform announced that the first model of Anthropic's newly released Claude 5.5 series, Claude Opus 5.5, is officially online, with API and Web Chat both open for simultaneous experience. This model is designed for long-cycle Agent programming and complex knowledge work, achieving Claude Fable 5.1 levels in most tasks, while reducing operating costs by about 40% compared to Opus 5.The model supports 1M Token ultra-long context and up to 128K output, demonstrating leading capabilities in Computer Use and multi-step automation scenarios. From today, developers and users can directly access Claude Opus 5.5 through the B.AI platform. You are welcome to log in to chat.b.ai/chat to experience it immediately.

On Tuesday, Anthropic released Claude Opus 5.5, the first model in its Claude 5.5 series. Anthropic stated that the new model's performance on most tasks has reached the level of its most expensive flagship model, Claude Fable 5.1, but the operating costs are 20% lower than the previous generation Opus 5 and 60% lower than Fable 5.1. In terms of pricing, the input and output token prices for Opus 5.5 are $4 per million and $20 per million, respectively, while the cache read price has dropped to $0.2 per million.In benchmark testing, Opus 5.5 scored 66.4% on Terminal-Bench 4, higher than Fable 5.1's 55.8% and GPT-6 Astra's 57.9%; FrontierCode scored 54.4%, higher than Fable 5.1's 50.3%; GDPval-AA v2.1 scored 1846, higher than Fable 5.1's 1735. However, GPT-6 Astra still leads Opus 5.5 in the AutomationBench and Terminal-Bench-Science 0.1 tests.This is the first model released after Anthropic CEO Dario Amodei called on the industry to slow down the pace of AI capability enhancement, and it continues to use the same cybersecurity and biosafety measures as Fable 5.1.
