TechCrunch reports that AI infrastructure startup Together AI has raised $800 million at an $8.3 billion valuation. The company is described as a neocloud provider focused on hosting open-source models, and the report says its prior round in early 2025 valued it at $3.3 billion.

Why it matters: This is a major financing for AI infrastructure and a strong signal that investors continue to back cloud providers built around open-source model access and GPU capacity. The valuation jump suggests rising demand for alternative AI compute and model-hosting platforms outside the biggest incumbent clouds.
