Frequently asked questions
Free access, setup, and what to expect.
Free API access for Mercury 2.5 is listed through Vercel AI Gateway, but a specific request or token allowance isn’t available in the listed data. Check the Mercury 2.5 provider pricing and rate limits for what’s included and any account requirements.
To use Mercury 2.5, choose one of the listed Mercury 2.5 API providers and follow the provider’s account and API-key setup guide. Copy the Mercury 2.5 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.
Mercury 2.5 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 Mercury 2.5 documentation for supported file types and request formats.
Mercury 2.5 has a listed context window of 260K 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 Mercury 2.5 may be smaller than the context window and can vary by provider.
Mercury 2.5 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.
