OpenRouter
OpenRouter is a unified API routing platform for large language models that provides a standardized interface for accessing models from multiple providers, including OpenAI, Anthropic, and Google. Users can invoke and switch between models through a single API endpoint. The platform supports model price comparison, usage tracking, and automatic fallback mechanisms, offering developers flexible model selection and cost management capabilities.
Core Facts
Muse Wonder's API pricing is $4 per million input tokens and $20 per million output tokens, offered through Meta's coding service platform.
Mistral Large 4 is priced at approximately $0.68 per million input tokens and $2.09 per million output tokens, with a 50% discount for the first two weeks.
Configuring DeepSeek Harness requires pasting the API Key into the Edit DeepSeek input field in the model options on the settings page and saving.
Timeline (last 90 days)
Vercel AI Gateway is a unified API gateway service that allows developers to call models from multiple vendors through a single interface, similar to OpenRouter.
OpenRouter's default model remains unchanged as Claude Sonnet 5.5.
NanoAgent supports OpenAI, Groq, Anthropic, DeepSeek, OpenRouter, as well as any self-hosted endpoint compatible with the OpenAI protocol (such as Ollama and llama.cpp server), and switching providers requires changing only one line of configuration.
OpenRouter uses model IDs in the format anthropic/claude-sonnet-5.5, while AtmoRouter uses the format cc/claude-sonnet-5-5.
According to public /models API data, AtmoRouter prices Claude Sonnet 5.5 at $0.50/$2.50 per million tokens, while OpenRouter prices it at $2.00/$10.00.
OpenRouter passes through at the provider's original price without taking a margin, instead charging a 5.5% fee (minimum $0.80) at the top-up stage, and 5% for cryptocurrency payments.
Muse Spark Open can be called on the day of release through platforms such as Baseten, Fireworks AI, Groq, Modal, Nebius, OpenRouter and Together AI.
Cohere's trial keys and Mistral's La Plateforme free tier are explicitly for evaluation only, not production; OpenRouter's terms prohibit reselling API access.
The daily cap for OpenRouter free models jumps from a small quota to a larger quota after the account purchases credits, and the error text and x-ratelimit-reset-requests header indicate the window that was closed.
Vendors such as Gemini, Groq, NVIDIA NIM, OpenRouter, Cloudflare Workers AI and Cerebras provide OpenAI-compatible chat format endpoints.
