Overview
Gemini 2.5 Flash stands out for Gemini 2.5 workhorse for price-performance and Low-latency reasoning for high-throughput workloads. It is best suited to production reasoning and multimodal product flows.
Multimodal
Supports mixed text-image input and can use a 1M-token context window for longer material.
Tool calling
Can call tools or functions, so product flows can connect model output to backend actions.
Streaming
Supports streamed responses for chat, assistants, and interfaces that need visible incremental output.
Prompt cache
Supports prompt caching patterns for repeated context and longer production conversations.
Reasoning
Better suited for multi-step analysis, planning, and tasks that need deliberate reasoning.
Structured output
Can return machine-readable structures for extraction, automation, and application logic.
Model maker
Google DeepMind (Gemini)
Called through SeaLink's unified account, balance, and OpenAI-compatible API.
Protocol
OpenAI-compatible Chat Completions
