Anthropic builds the Claude family of AI models, known for their strong reasoning capabilities, large context windows (up to 200K tokens), and emphasis on AI safety. Claude is widely regarded as one of the best models for coding, analysis, and long-document understanding. Anthropic pioneered Constitutional AI and the Model Context Protocol (MCP), an open standard for tool use and agent interoperability. The company serves enterprise customers through its API and the Claude.ai consumer product, with a focus on building reliable, steerable, and honest AI systems.
Guide Labs is building the first inherently interpretable LLMs. Their open-source Steerling-8B model features a novel concept layer inserted into the transformer architecture that makes every generated token traceable back to its training data. Unlike post-hoc explainability tools, Guide Labs bakes interpretability directly into the model, achieving 90% of standard model capability with less training data. YC-backed with $9M seed.
Companies that train and release their own large language models and foundation models. These organizations invest in large-scale model training, publish research, and offer API access to their proprietary models.
