Z.ai: GLM 5 Turbo

GLM-5 Turbo implements a latency-optimized inference pipeline specifically tuned for agent-driven workflows where sub-second response times are critical. The model uses architectural optimizations (likely quantization, KV-cache efficiency, and token prediction batching) to deliver faster inference than standard variants while maintaining reasoning quality in multi-step agent scenarios like OpenClaw environments where repeated forward passes are common.

GLM-5 Turbo maintains conversation state across multiple agent turns, preserving context from previous reasoning steps, tool calls, and observations. The model implements efficient context windowing that allows agents to reference prior decisions without re-encoding the entire history, using techniques like sliding-window attention or hierarchical context compression to keep token usage manageable while preserving agent memory.

GLM-5 Turbo supports function calling via structured schemas that agents can invoke to interact with external tools and APIs. The model generates tool calls in a format compatible with agent frameworks, likely using JSON schema definitions or OpenAI-style function calling format, enabling agents to orchestrate multi-step workflows that combine reasoning with external tool execution.

GLM-5 Turbo supports token-by-token streaming output via OpenRouter's streaming API, allowing agents and applications to receive partial results in real-time rather than waiting for complete generation. This enables responsive agent UIs, early stopping based on partial outputs, and real-time monitoring of agent reasoning as it unfolds, critical for interactive agent systems.

GLM-5 Turbo is offered via OpenRouter's usage-based pricing model, where costs scale with input and output tokens consumed. The model provides a cost-efficient alternative to larger models for agent workloads, with transparent per-token pricing that allows builders to estimate costs for agent workflows and optimize token usage through prompt engineering or context management.

GLM-5 Turbo is specifically optimized for OpenClaw-style agent scenarios, a framework for evaluating and benchmarking agent performance. The model's architecture and inference pipeline are tuned to handle OpenClaw's specific requirements: rapid decision-making, tool orchestration, and evaluation metrics. This enables seamless integration with OpenClaw benchmarks and agent evaluation frameworks.
