About This Site
Open-source database for comparing AI models, providers, specifications, and pricing Models.dev is a comprehensive open-source database of AI model specifications, pricing, providers, capabilities, context limits, output limits, release dates, and update dates. It provides provider-agnostic model metadata, lists the providers serving each model, and organizes canonical models by laboratory or author. Users can compare models such as GPT-6 Astra across multiple providers, review features including reasoning, tool calling, structured output, temperature support, and weights availability, and access the data through JSON APIs or a type-safe SDK.

EmpirioLabs AI
Specialized AI model hosting for open, proprietary, and custom stacks
EmpirioLabs AI is a low-cost AI infrastructure platform for developers. We host open-source models on our own infrastructure, run optimized proprietary endpoints, and bring model APIs, a browser playground, Hosted Agents, GPU Cloud, and generation templates into one place. Browse production-ready text, image, video, audio, 3D, search, and reasoning models, compare live pricing, test models in the playground, or launch video workflows from ready-made templates. Hosted Agents start at $5/month, GPU Cloud is billed by the second, and select models are discounted up to 90%.
Hathora
Platform for building low-latency voice AI agents with ASR, TTS, and LLM models.
Hathora Models provides a platform for building voice agents on open-source or closed models with zero DevOps. It offers low-latency ASR (Automatic Speech Recognition), TTS (Text-to-Speech), and LLM (Large Language Model) models that run in 14 regions for ultra-low latency. Users can start instantly on shared endpoints and upgrade to dedicated infrastructure for privacy, compliance, or VPC requirements. The platform allows users to explore, test, and deploy production-ready models, bring their own models or custom containers, and utilize a "Chain tool" for interactive voice AI pipelines.
