Free GPT Grok Gemini Claude API

OkRouter is an API gateway that puts many large language models behind one key and one endpoint. Instead of maintaining separate accounts and client libraries for each vendor, developers call a single unified interface that reaches models from OpenAI, Anthropic and Google alongside a catalog of open source models. The service presents itself as a drop in replacement for the OpenAI SDK, with Python, Node.js and curl examples on the home page. It targets application teams that want provider flexibility without rewriting integration code. Smart routing selects a provider for each request, and the platform adds activity logs with export, budgets and spend controls, prompt caching, preferred vendor selection and administrative controls. Enterprise accounts can add single sign on, SOC 2 compliance and dedicated throughput. The vendor lists compatibility with common frameworks and providers including Mistral, Llama, Gemini, DeepSeek, Hugging Face and LangChain. Pricing is published as three tiers rather than fixed subscription amounts. The Free tier carries no platform fee, covers more than 25 free models across six providers, caps usage at 50 requests per day and offers community support. A pay as you go tier opens more than 500 models across more than 60 providers with high global limits, no minimum spend, token prices set by the model chosen, and email support. Enterprise pricing is custom, with volume commitments, optional dedicated limits and a support agreement that includes a shared Slack channel. One caveat is worth noting. The about page still carries unfinished template content, including team member entries labeled only as placeholders, so the site does not identify the people or company behind the service. Buyers routing production traffic through a gateway may want that detail confirmed directly before committing.
