Fireworks AI has launched GLM 5.2 Fast, a model designed for agentic workflows that operates 2-3 times faster than its standard version. This enhanced speed is crucial for agents that process large contexts, write plans, and utilize tools, making them more practical and cost-effective. The model supports a 1 million token context window and features optimized prompt caching, offering significant discounts for reused context, which is a major cost factor in agentic operations. GLM 5.2 Fast is built with a specialized architecture combining Mixture-of-Experts (MoE) and DeepSeek Sparse Attention with IndexShare, allowing for efficient processing of long contexts by focusing attention on the most relevant parts of the input.
