OpenAI releases GPT-5.5 series models

OpenAI has announced the GPT-5.5 series, describing it as the most intelligent and intuitive model version to date. Compared to GPT-5.4, the new models deliver stronger performance in coding and debugging, online research, and generating documents and spreadsheets, while also supporting cross-tool collaboration to execute complex tasks. Users can input multi-step, unstructured requests, and the model can automatically handle task planning, tool invocation, result verification, and uncertainty management. In Codex scenarios, GPT-5.5 significantly reduces token usage and introduces more robust safety mechanisms.

GPT-5.5 will be gradually rolled out to ChatGPT Plus, Pro, Business, and Enterprise users, and will be integrated into the Codex platform. The Pro tier will offer more advanced capabilities. Source

Google introduces two AI chips: TPU 8t and 8i

At the Google Cloud Next 2026 conference, Google unveiled two new generations of custom AI ASIC chips: TPU 8t and TPU 8i, optimized for training and inference scenarios respectively, while also supporting cross-scenario workloads.

The TPU 8t is designed for large-scale, compute-intensive training tasks, focusing on improved compute throughput and vertical scaling bandwidth, delivering higher efficiency in complex model training. The TPU 8i, on the other hand, is optimized for low-latency inference and AI agent workloads, offering higher memory bandwidth and integrating a CAE (on-chip acceleration engine). It is equipped with 384 MB of on-chip SRAM and 288 GB of off-chip HBM, reducing data transfer overhead during execution and lowering latency.

At the cluster level, the TPU 8i Pod scale has increased from 256 chips in the previous generation to 1,152 chips. A single Pod delivers 8.67× higher FP8 compute performance and 5.74× greater HBM memory capacity. Google states that the overall energy efficiency of the new TPU 8t and TPU 8i is approximately double that of the previous-generation TPU Ironwood. Source

Tencent Cloud issues Xinference supply chain poisoning risk advisory

On April 23, Tencent Cloud released a security advisory regarding a supply chain poisoning risk affecting the open-source PyPI inference framework Xinference. The advisory states that affected versions may contain malicious code when installed or imported, potentially exfiltrating sensitive data—including cloud platform credentials, API keys, SSH keys, cryptocurrency wallet information, database credentials, and environment variables—to attacker-controlled command-and-control servers.

Tencent Cloud noted that such risks typically originate from tampering within the software supply chain and may pose significant threats to AI inference environments and related infrastructure. Affected users are advised to immediately uninstall compromised versions, scan systems for backdoors and residual files, and rotate critical credentials and keys as soon as possible. A comprehensive security audit is also recommended to assess potential impact and strengthen system defenses. Source
