Open-weight models 3

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.
Demo platform for OpenAI's open-weight models for developers. The gpt-oss playground is a demo platform designed for developers to explore OpenAI’s open-weight models, specifically gpt-oss-120b and gpt-oss-20b. It allows users to interact with these models and observe their reasoning capabilities.
Managed AI infrastructure for open models, agents, and scalable private deployments FlexAI is an agent-native AI infrastructure platform that provides managed inference for more than 20 open-weight models through one OpenAI-compatible API key. It supports text, vision, code, reasoning, embeddings, speech, audio, and image-generation workloads. Users can start with serverless model access, then scale to dedicated GPU endpoints, fine-tuning, and private AI cloud deployments across VPC, on-premises, or air-gapped environments. FlexAI also offers agent tools such as tool calling, streaming, structured outputs, approvals, governance, and audit trails.
