Anthropic hits $900B (yes, billion)

TechCrunch

Anthropic is raising $50 billion at a $900 billion valuation, potentially exceeding OpenAI's worth, as the AI company prepares for an IPO later this year while generating nearly $40 billion in annual revenue.

OpenAI traced an increase in goblin-related metaphors in GPT models to reinforcement learning rewards for a 'Nerdy' personality feature, revealing how reward signals can create unintended behavioral quirks that spread across model capabilities through training feedback loops.

SMG solves the Python GIL bottleneck in LLM serving by disaggregating all CPU workloads (tokenization, tool orchestration, multimodal processing) into a pure Rust gRPC gateway, delivering up to 3.5x throughput gains in production scenarios. The project has been adopted by major cloud providers and integrated upstream into vLLM and TensorRT-LLM.

GLM-5V-Turbo is a foundation model built natively for multimodal agents, integrating visual perception directly into reasoning and planning rather than treating it as an add-on to language models. The approach shows strong results in visual tool use and agentic tasks while offering practical insights for multimodal agent development.
