Model Information

Display Name: GLM 5.3 Flash

API Model ID: zai-org/glm-5.3-flash

Category: Image To Text

Description: GLM-5.3-Flash is Z.ai (Zhipu AI)'s natively multimodal flash model — a 320B-parameter Mixture-of-Experts (~18B active) released under the MIT license, built for cheap, high-throughput coding and long-horizon agentic work. **Key Features:** - 1,000,000-token context window (repository-scale) - Up to 131K output tokens - Mixture-of-Experts: 320B total / ~18B active - Native multimodal input: text, images and video - Reasoning (thinking) always available, hybrid attention - Function/tool calling and JSON structured outputs - Prompt caching for cheaper repeated context **Best For:** - High-volume agentic coding at flash pricing - Long-horizon tool-using workflows - Vision + code tasks in a single call

Context Window: 1,048,576 tokens

Max Output: 131,072 tokens

Pricing

• input: $1.00
• output: $5.00
• cached: $0.20

Available Parameters

• temperature: Controls randomness (0-2). Higher = more creative, lower = more deterministic. Default: 0.7 (Options: 0, 0.3, 0.5, 0.7, 1.0, 1.5, 2.0)
• top_p: Nucleus sampling threshold (0-1). Default: 0.9 (Options: 0.1, 0.5, 0.7, 0.9, 0.95, 1.0)
• top_k: Limits sampling to top K tokens. Default: off (Options: 10, 20, 40, 50, 100)
• max_tokens: Maximum tokens to generate. Default: 4096 (Options: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072)
• thinking: Toggle adaptive reasoning. Omit for the model default. On the native Z.ai host thinking cannot be disabled. (Options: on, off)
• response_format: Output format for structured responses (Options: text, json_object, json_schema)
• tools: Function/tool definitions for agentic workflows
• stop: Up to 4 sequences where the API stops generating further tokens
