Together AI has reached an $8 billion valuation after raising over $1 billion in Series C funding, more than doubling its worth since early 2025. The company, which provides infrastructure for open-source AI models, now serves 450,000 developers and claims 2-3x faster performance than major cloud providers.

The funding round closed in April 2026 with a $1 billion primary tranche and $44.89 million extension. This represents roughly a 2.4x increase in valuation over about 14 months, pushing cumulative funding to approximately $1.58 billion. The surge reflects growing demand for alternatives to closed AI models from OpenAI and Anthropic.

On May 15, Together AI partnered with Pearl Research Labs to integrate blockchain-based cost subsidies. Pearl's Proof-of-Useful-Work protocol uses matrix multiplications instead of traditional mining, with emissions offsetting inference costs by over 25% for certain models. This creates a tangible use case for crypto tokens beyond speculation.

The partnership gives Together AI a significant edge in the crypto-AI space. While decentralized compute networks like Akash and Render pursue similar models, Together AI's scale and developer base provide distribution advantages most crypto-native projects lack. This positions them at the intersection of two rapidly growing sectors.
