Polymarket's probability that "Claude Fable 5 will resume service for US customers by July 1st" has risen to 73%, a 33% increase in the last 24 hours.
According to Odaily Seer, the probability of Claude Fable 5 being restored for US customers by July 1st on Polymarket has risen to 73%, a 33% increase in the past 24 hours. If Anthropic reopens Claude Fable 5 (or Claude Mythos, or a version of the same model) to the US public before the specified date, this event will be counted as "Yes"; otherwise, it will be counted as "No". Eligible restoration methods include public beta or a public waiting list; closed beta and private access are not counted. Other models such as Haiku, Sonnet, and Opus are not counted by default unless confirmed to be the same model as Claude Fable 5. The count is primarily based on Anthropic's official announcements, while also referencing mainstream media consensus reports. Due to the US government's export controls citing national security concerns, Anthropic urgently suspended global access to Claude Fable 5 a few days after its release on June 9th. While the restrictions primarily targeted foreign users, Anthropic ultimately closed access to all users, including those in the United States, due to the difficulty in verifying user identities in real time, and switched requests to weaker models such as Opus 4.8. Anthropic is currently in high-level communication with the White House to discuss issues such as model capabilities and potential jailbreak risks. The company has publicly stated that the ban may have stemmed from a misunderstanding and is working to restore access. Odaily Seer continues to monitor the prediction market, seeing changes before pricing.

Anthropic releases Project Fetch Phase 2: Claude Opus 4.7 boasts a 10x speedup in robotics tasks.
According to Odaily Odaily, Anthropic has released the results of the second phase of its "Project Fetch" experiment, evaluating the improved capabilities of its latest model in real-world robotic operations. The experiment, conducted in August 2025, involved Anthropic employees, who were not robotics experts, using off-the-shelf quadruped robots to complete a series of complex tasks. The results compared performance using the Claude model with human assistance versus relying solely on humans and the internet. The results showed that the latest Claude Opus 4.7 model, operating fully autonomously, significantly outperformed the human team on average in all achievable tasks, demonstrating at least a 10-fold speed improvement. Anthropic stated that this progress is not specifically for robot training, but rather a result of expanding the capabilities of general-purpose large models. He pointed out that AI is gradually moving from "assisting humans in using tools" to the early stage of "directly manipulating physical tools," similar to the path of evolution towards proxy programming in the field of software engineering.
