ai model / gemini flash 3.5 / multimodal

Why It Matters

Gemini 3.5 Flash introduces much faster multimodal inference and agentic capabilities at substantially lower cost than comparable flagship models, affecting architecture, deployment, and cost planning for AI services. Tech teams should reassess model selection, latency budgets, and token-cost economics when designing agents, multimodal apps, and inference pipelines.

Latest Changes

• Google released Gemini 3.5 Flash, now publicly available
• Performance reportedly approaches GPT-5.5, stronger on agentic and multimodal tasks
• API pricing set at $1.50 per 1M input tokens and $9.00 per 1M output tokens with 1M token context window
• Caching/input cache price reported at $0.15 per 1M tokens, lower than GPT-5.5 equivalents
• Inference speed claimed about 4x faster than other flagship models
