Gemini 3.5 Flash-Lite is a low-latency, cost-effective multimodal model optimized for high-throughput, low-cost execution for subagent tasks and document parsing. The model supports text, image, video, audio, and PDF inputs, and is designed for high-volume agentic workflows, simple data extraction, and applications where latency and API cost are the primary constraints.
Gemini 3.5 Flash Lite vs GLM 5.2
Output tokens cost $2.50 per million on Gemini 3.5 Flash Lite and $3.94 per million on GLM 5.2. Input tokens cost $0.30 per million on Gemini 3.5 Flash Lite and $1.13 per million on GLM 5.2. Cached input tokens are billed at $0.03 per million on Gemini 3.5 Flash Lite and $0.28 per million on GLM 5.2. Context lengths are 1,048,576 tokens on Gemini 3.5 Flash Lite and 1,000,000 tokens on GLM 5.2. Time to first token (TTFT) measured on AIHubMix is 0.4s on Gemini 3.5 Flash Lite and 0.6s on GLM 5.2. Measured output throughput is 66.3 tok/s on Gemini 3.5 Flash Lite and 44.3 tok/s on GLM 5.2. On the LMArena coding leaderboard Gemini 3.5 Flash Lite scores 1500 and GLM 5.2 scores 1505.
GLM 5.2GLM-5.2 is Z.ai’s flagship model for the era of long-horizon tasks. With a truly usable 1M-token context window, it can handle project-level engineering context, execute long-running tasks more reliably, follow engineering standards more consistently, and complete the full development workflow from requirements to multi-platform deployment in a single task.
