Free access, setup, and what to expect.
Free API access for GLM 4.5 Air is listed through Vercel AI Gateway, but a specific request or token allowance isn’t available in the listed data. Check the GLM 4.5 Air provider pricing and rate limits for what’s included and any account requirements.
To use GLM 4.5 Air, choose one of the listed GLM 4.5 Air API providers and follow the provider’s account and API-key setup guide. Copy the GLM 4.5 Air model ID and connection settings for your chosen provider into your app or API client. Model IDs can differ between providers. API requests go directly to the provider; Free Models is a comparison site.
GLM 4.5 Air accepts text as listed input formats. Listed output formats include text. Image or audio input support does not imply image or audio generation. Check the chosen provider’s GLM 4.5 Air documentation for supported file types and request formats.
GLM 4.5 Air has a listed context window of 131K tokens. Tokens are small pieces of content rather than a word count. Instructions, conversation history, and other inputs use context space, and the response also needs room. The maximum output length for GLM 4.5 Air may be smaller than the context window and can vary by provider.
GLM 4.5 Air has both reasoning and tool calling listed as supported capabilities. Reasoning enables additional processing for complex problems. Tool calling allows a model to request functions that your app executes. Check the chosen provider’s documentation for capability availability and setup.
