SGLang Spins Out as RadixArk at $400M Valuation Amid Inference Infrastructure Boom
RadixArk, a commercial startup built around the popular open-source SGLang tool for AI model inference optimization, has raised funding at a $400 million valuation led by Accel. The company, founded by former xAI engineer Ying Sheng and originating from UC Berkeley's Databricks co-founder Ion Stoica's lab, focuses on making AI models run faster and more efficiently. This follows a broader trend of inference infrastructure startups raising significant capital, with competitors like vLLM pursuing $160M at $1B valuation and Baseten securing $300M at $5B valuation.
Skynet Chance (+0.01%): Improved inference efficiency makes AI deployment more economically viable and scalable, potentially enabling wider proliferation of powerful AI systems with less oversight. However, the impact on control mechanisms or alignment is minimal, representing only incremental infrastructure improvement.
Skynet Date (-1 days): More efficient inference reduces operational costs and accelerates AI deployment cycles, making advanced AI systems more accessible and deployable at scale sooner. The significant funding influx into this infrastructure layer indicates rapid commercialization of AI capabilities.
AGI Progress (+0.02%): Inference optimization is critical infrastructure that enables more cost-effective deployment and scaling of increasingly capable AI models, removing economic barriers to running larger models. The focus on reinforcement learning frameworks (Miles) specifically supports development of models that improve over time, a key AGI characteristic.
AGI Date (-1 days): The massive funding wave ($400M for RadixArk, $300M for Baseten, $250M for Fireworks AI) and rapid commercialization of inference infrastructure significantly reduces the cost and time barriers to deploying and iterating on advanced AI systems. This acceleration of the inference layer directly enables faster experimentation and deployment of increasingly capable models toward AGI.
Nvidia Unveils Rubin Architecture: Next-Generation AI Computing Platform Enters Full Production
Nvidia has officially launched its Rubin computing architecture at CES, described as state-of-the-art AI hardware now in full production. The new architecture offers 3.5x faster model training and 5x faster inference compared to the previous Blackwell generation, with major cloud providers and AI labs already committed to deployment. The system includes six integrated chips addressing compute, storage, and interconnection bottlenecks, with particular focus on supporting agentic AI workflows.
Skynet Chance (+0.04%): Dramatically increased compute capability (3.5-5x performance gains) and specialized support for agentic AI systems could accelerate development of autonomous AI agents with enhanced reasoning capabilities, potentially increasing challenges in maintaining control and alignment. The infrastructure-focused design enabling long-term task execution may facilitate more independent AI operation.
Skynet Date (-1 days): The substantial performance improvements and immediate full production status, combined with widespread adoption by major AI labs (OpenAI, Anthropic), significantly accelerates the timeline for deploying more capable AI systems. The dedicated support for agentic reasoning and the projected $3-4 trillion infrastructure investment over five years indicates rapid scaling of advanced AI capabilities.
AGI Progress (+0.04%): The 3.5x training speed improvement and 5x inference acceleration represent substantial progress in overcoming computational bottlenecks that limit AGI development. The architecture's specific design for agentic reasoning and long-term task handling directly addresses key capabilities required for general intelligence, while the new storage tier solves memory constraints for complex reasoning workflows.
AGI Date (-1 days): The immediate availability in full production, combined with massive performance gains and widespread adoption by leading AGI-focused labs, significantly accelerates the timeline toward AGI achievement.

DeepSeek Introduces Sparse Attention Model Cutting Inference Costs by Half
DeepSeek released an experimental model V3.2-exp featuring "Sparse Attention" technology that uses a lightning indexer and fine-grained token selection to dramatically reduce inference costs for long-context operations. Preliminary testing shows API costs can be cut by approximately 50% in long-context scenarios, addressing the critical challenge of server costs in operating pre-trained AI models. The open-weight model is freely available on Hugging Face for independent verification and testing.
Skynet Chance (-0.03%): Lower inference costs make AI deployment more economically accessible and sustainable, potentially enabling better monitoring and alignment research through reduced resource barriers. However, it also enables broader deployment of powerful models, creating a minor mixed effect on control mechanisms.
Skynet Date (+0 days): Reduced inference costs enable more sustainable AI scaling and wider deployment, but this is primarily an efficiency gain rather than a capability breakthrough that would accelerate uncontrolled AI development. The modest deceleration reflects that economic sustainability may slow rushed deployment.
AGI Progress (+0.02%): The sparse attention breakthrough represents meaningful architectural progress in making transformer models more efficient at handling long-context operations, addressing a fundamental limitation in current AI systems. This optimization enables more practical deployment of advanced capabilities needed for AGI.
AGI Date (+0 days): Cutting inference costs by half significantly reduces economic barriers to scaling and deploying advanced AI systems, enabling more organizations to experiment with and advance long-context AI applications. This efficiency breakthrough accelerates the practical timeline for developing and deploying AGI-relevant capabilities.
Spanish Startup Raises $215M for AI Model Compression Technology Reducing LLM Size by 95%
Spanish startup Multiverse Computing raised €189 million ($215M) Series B funding for its CompactifAI technology, which uses quantum-computing inspired compression to reduce LLM sizes by up to 95% without performance loss. The company offers compressed versions of open-source models like Llama and Mistral that are 4x-12x faster and reduce inference costs by 50%-80%, enabling deployment on devices from PCs to Raspberry Pi. Founded by quantum physics professor Román Orús and former banking executive Enrique Lizaso Olmos, the company claims 160 patents and serves 100 customers globally.
Skynet Chance (-0.03%): Model compression technology makes AI more accessible and deployable on edge devices, but doesn't inherently increase control risks or alignment challenges. The focus on efficiency rather than capability enhancement provides marginal risk reduction through democratization.
Skynet Date (+0 days): While compression enables broader AI deployment, it focuses on efficiency rather than advancing core capabilities that would accelerate dangerous AI development. The technology may slightly slow the concentration of AI power by enabling wider access to compressed models.
AGI Progress (+0.02%): Significant compression advances (95% size reduction while maintaining performance) represent important progress in AI efficiency and deployment capabilities. This enables more widespread experimentation and deployment of capable models, contributing to overall AI ecosystem development.
AGI Date (+0 days): The dramatic cost reduction (50%-80% inference savings) and ability to run capable models on edge devices accelerates AI adoption and experimentation cycles. Broader access to efficient AI models likely speeds up overall progress toward more advanced systems.
