Coldcard has released the latest firmware 5.6.1 (Mk4/Mk5) and 1.5.1Q (Q). This update is based on a three-week security review following the emergency fix on July 31, addressing security risks brought by the previous mnemonic generation attack. Each newly generated mnemonic must now include at least one source of user entropy, including at least 65 irregular keystrokes, 50 physical dice throws, or 128 physical coin flips, combined with fresh entropy provided by STM32 TRNG, SE1, and SE2. The new firmware also adds instant staged PSBT verification before signing, strengthens USB connection and firmware update boundaries, improves Delta Mode isolation mechanisms, fixes active wallet backup issues, enhances random number generator initialization and fault checking, adjusts SIGHASH default settings, and includes multiple security and correctness improvements. Coldcard stated that this update aims to further reduce the risk of device attacks. The official reminder notes that updating the firmware cannot fix existing mnemonics generated by previously affected firmware. If users' mnemonics fall within the scope of this security advisory, they should first update the device, then generate and verify a completely new mnemonic, and migrate funds to the new wallet. Coldcard recommends that all Mk4, Mk5, and Q users update their devices promptly and verify the signature of the downloaded firmware.
: AI programming platform Replit has launched a new feature called Free Mode, powered by OpenAI's latest low-cost model GPT-5.6 Luna, aimed at reducing the cost for users to access AI programming tools and enhancing the value for paid subscribers.Replit stated that Free Mode is currently available to Core and Pro subscribers, corresponding to the $20/month and $100/month plans, respectively. This mode will serve as the default experience, allowing users to prioritize the low-cost model for chat, brainstorming, and simple programming tasks. When a task requires stronger reasoning capabilities, Replit Agent will automatically switch to a higher-performance model.Michele Catasta, Head of AI at Replit, said that the launch of Free Mode is made possible by OpenAI significantly cutting the cost of the GPT-5.6 Luna model. At the end of July, OpenAI reduced the API price of this model by approximately 80%, achieving cost reduction through improved model efficiency rather than relying on additional computing resources.

The service will initially be available only to specific customers via the OpenAI API, with OpenAI planning to gradually expand access as compute capacity grows. OpenAI has already used this mode internally for incident response and plans to use speed as a new pricing lever.

HyperliquidNews posted on X platform, stating that to launch a HIP-3 market, a deployer must lock 500,000 hyperliquid:native and purchase a ticker for each created market. As the largest HIP-3 deployer, Trade[XYZ] has purchased 103 tickers and launched 87 markets. The minimum cost of a ticker is 500 hyperliquid:native, currently valued at approximately $31,400. HIP-3 revenue comes from transaction fees generated by each market, with 50% going to the deployer and 50% to the Assistance Fund, which uses the proceeds to buy back and burn hyperliquid:native. To encourage trading activity in HIP-3 markets, Hyperliquid has introduced Growth Mode, reducing transaction fees by 90%; deployers can choose whether to enable it, with few exceptions. Despite the fee reduction, 40 of Trade[XYZ]'s 87 launched markets have generated revenue exceeding 500 hyperliquid:native, meaning they have at least covered the initial ticker cost, accounting for 46% of all launched markets. This data only calculates ticker costs and does not include other operating expenses. As long as trading activity continues, each ticker will continue to generate revenue. Some tickers have generated millions of dollars in fees for Hyperliquid and Trade[XYZ] respectively. For example, GOLD has generated over $4.6 million in fees for each party. GBP is currently the ticker with the lowest profitability, generating $610 in revenue for Trade[XYZ] so far.

Tibo, a core member of OpenAI Codex, posted on X platform stating that previously, it was too easy for users to enable high-compute mode without fully explaining its impact on usage quotas. The large-scale revamp of the desktop application made common features like chats and projects difficult to find. Additionally, promotional efforts overly focused on ChatGPT Work, leading some Codex users to mistakenly believe that Codex would be phased out in the future. Furthermore, the new version also caused issues with some multi-agent workflows, plugin functions, and other user experiences.In response to the above issues, OpenAI has already rolled out the first batch of improvement measures, including adjusting default settings and the model selector to prevent users from accidentally using high-cost configurations, fixing several plugin submission issues, optimizing the presentation of Codex within the product, and resolving some desktop experience problems.Additionally, over the past 24 hours, OpenAI has been continuously collecting user feedback, analyzing usage patterns, and communicating with users. Although the market has shown strong interest in GPT 5.6 Sol and the web and mobile versions of ChatGPT Work, OpenAI also acknowledges that this update has multiple issues.As of now, two rounds of Codex and ChatGPT Work usage quota top-ups have been completed. The next larger-scale update will be released next week, when chat and project features will return to the sidebar in a more familiar and customizable form. The platform will also enhance the visibility of usage quotas and reset times, further clarifying the respective applicable scenarios for ChatGPT Work and Codex.
