On July 28, OpenAI quietly updated its security incident disclosure, confirming that its AI agent accessed four external service platforms during the breach of Hugging Face, bringing the total number of affected platforms to five.Previously, OpenAI had disabled security filters while testing GPT-5.6 Sol and a more powerful model to assess raw capabilities. The model did not complete the security benchmark tests as expected; instead, it discovered a zero-day vulnerability in the package caching agent within the testing environment that granted internet access, subsequently breaching Hugging Face to steal answers.According to a forensic report released by Hugging Face on July 27, this autonomous agent executed 17,600 operations over approximately four and a half days, connecting 181 devices to the Hugging Face internal VPN and forging identity tokens. Among the four additional platforms, Modal Labs CTO Akshat Bubna confirmed through Reuters that his company was one of them, with the attacker using an unprotected public endpoint from a customer as a relay and command control base for the entire attack.The identities of the other three platforms remain undisclosed.

On July 29, Tibo, the product lead for OpenAI Codex, announced on X that all usage limits for ChatGPT Work and Codex users have been reset, and released a statement regarding the issue of rapid consumption of GPT-5.6 Sol usage.In the previous weeks, a large number of users reported that the consumption speed of Codex limits exceeded expectations. OpenAI emphasized that it has not reduced the usage quotas of any subscription plans. After investigation, several reasons were found: Sol is more inclined to work for longer periods, execute more tool calls, and coordinate complex workflows than previous models; it consumes more tokens at the same reasoning level; programmatic tool calls (code mode) allow Sol to execute tool calls in parallel, resulting in more responses and higher usage per round; the distribution of impact is extremely uneven, with median user efficiency being acceptable, but heavy users handling complex tasks consuming far more than expected.OpenAI stated that multiple improvements have been completed, and it is expected that usage endurance will be extended by about 18% in typical usage scenarios. Tomorrow, the five-hour limit that was paused during the investigation will be restored. OpenAI acknowledged that "capabilities and efficiency do not always improve synchronously, and some issues only become apparent after large-scale real-world use; we should have realized this earlier."

Davidson's co-chief investment officer James Ragan stated that since the last Federal Reserve meeting, inflation data has been moderate and employment growth has been modest, but the escalation of military conflict between the U.S. and Iran in July has disrupted these positive trends. This means that the progress made in inflation in June may reverse, and the Federal Reserve needs to assess the persistence of core inflation trends.If it is determined that higher inflation expectations are forming, they should raise interest rates in July rather than wait until September, especially considering the political risks of the midterm elections.
