FAQ
How much does Gemini Pro Experimental cost?
Public per-token pricing for Gemini Pro Experimental is not yet published. Submit a source on this page to help us add it.
What is the context window of Gemini Pro Experimental?
Gemini Pro Experimental supports a 1,000,000-token context window with up to 8,192 output tokens.
Does Gemini Pro Experimental support function calling?
Gemini Pro Experimental does not currently advertise function-calling support. For agentic workloads, prefer a tool-calling-capable model and route via Agent Command Center for fallback.
Is Gemini Pro Experimental good for production?
Gemini Pro Experimental is well-suited for long-context tasks — context window in the top 8% of peers and parallel tool calls — only 21% of chat models on Future AGI advertise this. Consider alternatives if you need agentic workflows — no advertised function-calling; use a tool-capable model and route via Agent Command Center for fallback.
How can I route to Gemini Pro Experimental with fallback?
Use Agent Command Center: a single OpenAI-compatible endpoint that supports cost-optimized routing, latency-aware retries, model fallback, and shadow traffic. Configure once, swap models without app changes.
