How can I compare chat model pricing and specifications?

Each model card shows live pricing, context window, maximum output, and capability labels. Open a model page for complete price rows, supported API protocols, and code examples. Final billing follows the live page prices and request details in the console.

How can I call chat models through HaoAI?

Models on this page use the same HaoAI API Key. The OpenAI-compatible Base URL is https://api.hao.ai/v1, and the Anthropic API Base URL is https://api.hao.ai/anthropic. Supported formats vary by model; refer to its detail page for the current protocol markers and complete model ID.

Which capabilities do HaoAI chat models support?

Capabilities vary by model. Model cards and detail pages show the capabilities currently listed in the live catalog. Every capability shown for a model is available through the HaoAI API; refer to that model's detail page for the current specification.
