OpenRouter doubles valuation to $1.3B on multi-model demand

Nvidia researchers have developed a technique that uses linear math to transfer key-value caches between different AI models without recomputing conversation history. The method enables enterprises to switch between small and large models mid-session while reducing compute costs and latency by 2.7 to 25 times compared to traditional recomputation, retaining up to 98% accuracy on compatible model pairs.

Ramp, a financial operations platform, has launched Router, an AI model routing service that allows users and companies to access and switch between multiple large language models through a single API. The service abstracts away the complexity of managing different LLM providers, enabling organizations to route requests dynamically across various models. This move positions Ramp to compete in the growing infrastructure layer for AI applications.

Alibaba released Qwen3.8-27B, a 27-billion-parameter open source model on Friday that runs locally without cloud APIs and delivers frontier-class coding and reasoning capabilities. Third-party benchmarks show it matches or exceeds proprietary models from months ago, with scores equivalent to OpenAI's GPT-5.6 Luna and outperforming Claude Opus 4.8 on agentic tasks. The model runs on consumer hardware when quantized to 4-bit, making frontier-class AI accessible without vendor dependency.

Anthropic's annualized revenue has reached $65 billion, with the AI model maker adding $18 billion in annualized revenue over a two-month period. The figure represents a significant acceleration in the company's commercial traction as demand for its Claude AI models grows. The milestone underscores the rapid scaling of revenue in the generative AI sector among leading model makers.
