Multiverse Computing

Multiverse Computing, S.L. is a Donostia-San Sebastian (Spain) quantum- and AI-software company whose commercial developer surface is the CompactifAI API — an OpenAI-compatible LLM inference service serving tensor-network-compressed versions of frontier open models (Hypernova 60B, Carina 60B, Mistral Small 3.1 Slim, Whisper Large V3 Turbo Slim) alongside uncompressed third-party models (GPT-OSS 120B, GLM 5.1/5.2, Quasar 438B, Qwen 3.6 27B, Nemotron 3 Nano Omni). The API is published at api.compactif.ai with regional EU and US endpoints, documented at docs.compactif.ai, billed pay-as-you-go per million tokens, and also sold through the AWS Marketplace. The company additionally sells Singularity, a quantum and quantum-inspired optimization product for finance, energy and manufacturing, which has no public developer documentation.

Multiverse Computing publishes 6 APIs on the APIs.io network, including Audio API, Batches API, Completions API, and 3 more. Tagged areas include Artificial Intelligence, Machine-Learning, LLM Inference, Model Compression, and Quantum Computing.

Multiverse Computing’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 24 more developer resources.
