OpenAI plans to officially release GPT-5.6 on July 7, a date that falls precisely on the expiration day of Anthropic's Claude Fable 5 paid plan usage limits, which the market views as a precise strike against its competitor. GPT-5.6 will feature three sub-models—Sol, Terra, and Luna—and introduce a "speed dial" function. Sol Ultra scored 91.9% in programming tests, surpassing Claude Mythos 5's 88.0%; Terra's performance matches GPT-5.5 but at half the price; and Luna is priced as low as $1 per million input tokens. GPT-5.6's API pricing is also highly aggressive, with Sol's input price at only half of Claude Fable 5's. Sources say OpenAI has locked its internal target window for July 7 to July 9.

Samsung Electronics delivered a quarterly scorecard worthy of the history books, but the market responded directly with a "sell the news" logic. The extreme gains in the memory chip sector had already priced in this surprise ahead of time, and the sharp correction in the stock price precisely confirms the market's deep skepticism over "how much better can the future get." Meanwhile, the precisely timed release of GPT-5.6 and Anthropic's overseas computing power land grab yesterday are reshaping the competitive landscape of the AI industry. SpaceX's inclusion in the Nasdaq 100 today marks the official entry of the space economy into mainstream technology indices.
