Overview
Gemini 2.5 Flash: Gemini 2.5 Flash is Google DeepMind's price-performance model for low-latency, high-volume work that still needs reasoning, with thinking supported. It accepts text, image, audio and video input across a 1,048,576-token context window, returns up to 65,536 tokens, and carries a January 2025 knowledge cutoff. Google now limits access to existing users while keeping the model served.
Mistral Small 3.1: Mistral Small 3.1 is Mistral AI's 24-billion-parameter multimodal model, accepting text and image input across a context window of up to 128,000 tokens and published under Apache 2.0. Mistral reports inference speeds of 150 tokens per second and compares it with Gemma 3 and GPT-4o Mini in the same weight class. Its size and licence make it one of the larger models that remains practical to self-host on a single machine.
Context window: Gemini 2.5 Flash accepts up to 1,000,000 tokens, Mistral Small 3.1 up to 128,000. Confirm the limit for your specific deployment channel before relying on it.
