OpenAI has published a new prompting guide for GPT-5.6 Sol, and its central recommendation runs against a year of prompt-writing habits: stop stuffing system prompts with extra instructions. The company says the better approach is outcome-first prompting—state the desired result, define success criteria, specify stopping conditions, and leave out process detail the model already handles on its own. According to OpenAI, internal coding-agent tests showed that leaner system prompts improved evaluation scores by about 10% to 15%, while reducing total token use by 41% to 66% and lowering costs by 33% to 67%. The guide argues that repeated rules, style notes that do not change behavior, and examples that add no functional value now act as noise rather than support. The update also marks a clear shift from the GPT-5 guide released in August 2025, which favored heavier scaffolding such as XML persistence blocks, detailed context-gathering templates, and narrated tool preambles. GPT-5.6, OpenAI says, needs fewer rails. The guide also introduces the text.verbosity parameter and a new section on Programmatic Tool Calling for workflows where code can filter, batch, or aggregate outputs before handing compact results back to the model.

Dragonfly partner Haseeb said on X that DeFi has not entered the “hacker doomsday” some had feared, even as models including GLM 5.2, Fable and GPT 5.6 are already live and being used by attackers. Citing chart data, he said 2026 DeFi losses are running at an annualized $1.89 billion based on year-to-date figures and the current pace. Total losses so far this year stand at about $986 million, below 2025 levels and still within the historical range. Haseeb said the more meaningful shift is in attack composition: the number of hacks has increased, but the size of each attack has fallen faster. He added that attackers are focusing more on smaller protocols and abandoned projects, while larger protocols have completed more security hardening. In his view, overall fund safety across DeFi has not deteriorated in a clear way.

SBI Holdings and the Solana Foundation have announced a strategic partnership focused on developing Japan’s domestic on-chain finance market, according to a Techub News item citing a post from @WuBlockchain. As part of the arrangement, the Solana Foundation will join SBI R3 Japan, which is set to be renamed SBI Solana Global, with the initiative moving forward alongside Sumitomo Mitsui Financial Group. The partnership is set to focus on several areas tied to institutional and regulated blockchain-based finance in Japan. These include yen-denominated stablecoins, tokenized real-world assets such as bonds and real estate, cross-border payments, and on-chain financial services for institutions. SBI said the move is intended to connect Japan’s regulated financial market with global blockchain liquidity. The company also framed the effort as part of a broader push to position Japan as an Asian hub for on-chain finance.
