According to BlockBeats, on September 7, South Korean semiconductor media outlet The Elec reported that Samsung Electronics is using probe stations from US-based FormFactor and Taiwan-based MPI to test silicon photonic integrated circuit (PIC) wafers, and plans to complete its independent PIC evaluation by the end of this year.

The report, citing industry insiders, stated that both FormFactor and MPI have passed TSMC's CPO and silicon photonics testing equipment verification. Samsung is using the same testing infrastructure as TSMC to conduct wavelength domain and frequency domain optoelectronic characteristic tests on the PIC wafer to verify whether the optical device achieves optical signal transmission and electro-optical conversion as designed.

Samsung previously commissioned external organizations such as imec in Belgium to conduct PIC wafer verification, and is currently building its own testing environment and conducting repeated evaluations. The company also plans to advance customer evaluations and has stated that mass production of related projects will begin in the second half of this year.

The report states that Samsung plans to launch its silicon photonics foundry service in 2027, providing optical device process technology, device libraries, and PDKs; at the same time, it will promote the development of optical engines combining EIC and PIC, and further expand the application of CPO from network switches to products such as GPUs and CPUs in the future.

According to Beating AI News, OpenAI's Codex now supports direct control of agents on Linux servers from mobile phones. Run `codex remote-control start` on the server, then generate a temporary pairing code using `codex remote-control pair`. Access the ChatGPT Remote page on your mobile phone, enter the pairing code, and you can connect to the machine. Codex still runs locally on the server; the mobile phone handles tasks, issuing new commands, and processing approvals.

This is particularly useful for GPU clusters and headless Linux servers. Researcher Tanishq Mathew Abraham used it to manage automated research experiments and training tasks on his Slurm GPU cluster from his mobile phone. It has also been successfully implemented in environments such as Ubuntu and Arch Linux by members of the community.

However, this feature is still labeled as Experimental by OpenAI. The official documentation isn't fully up-to-date either: while Developer Commands lists CLI pairing methods, the Remote Connections main documentation still states that phone pairing needs to be initiated from the Mac or Windows desktop app. There are also reports on GitHub of Linux and Android pairing failures and devices not displaying.

According to BlockBeats, on September 7th, Glassnode data showed that BTC is facing significant selling pressure around $83,000. All BTC holding addresses of all sizes have turned to net selling, which is the first time this has happened since early June, and the overall selling pressure in the market is rising.

Following the recent surge in BTC, whales and other holders have begun increasing their allocations, causing the market to face continued resistance around $83,000. However, the potential "golden cross" in BTC still provides some support for the bulls, and the short-term market trend will depend on whether buyers can absorb the current allocation pressure and break through this key resistance level.
