Released 32 days after GLM 5 · All Z.ai releases
GLM-5-Turbo is Z.ai's agent-focused variant, released March 15, 2026 and tuned from the ground up for OpenClaw and other complex agentic workflows rather than retrofitted from a general-purpose base. It builds on the GLM-5 architecture (744 billion parameters, around 40 billion active), supports a 200,000-token context window with up to 128,000-token output, and offers selectable thinking modes that trade compute for reasoning depth. What sets GLM-5-Turbo apart is its alignment for production agentic tasks: stable, accurate tool invocation, decomposition of multi-layered instructions into sub-steps, awareness of scheduled and persistent long-running tasks, and faster, more stable execution in high-throughput, long-chain workflows common in business automation. It can take tool descriptions, skill references, workspace details, and session state directly in its system prompt for modular instruction handling. Key capabilities include streaming output, function calling, context caching for extended conversations, structured JSON output, and Model Context Protocol (MCP) tool integration. Compared with models adapted for agents after training, GLM-5-Turbo inherits GLM-5's long-horizon planning and agentic coding strengths while running faster, making multi-step autonomous workflows more practical at production scale. Thinking mode enables internal reasoning before a response, with lighter modes for extraction and classification and deeper modes for complex instruction following and logical decomposition.

GLM-5-Turbo runs on 2 different routes through the Opper gateway. Compare residency, zero data retention and training posture at a glance, with full data-handling detail per route below.
One of GLM-5-Turbo's 2 routes is on the monitoring board, so the figure below is that provider's availability rather than the model's.
Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.
Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. 1 further route is not on the board yet. See uptime for every provider Opper monitors.
Each route hosting GLM-5-Turbo has its own privacy posture, residency, and GDPR terms. Postures are maintained by Opper with a last-verification timestamp.
Zero data retention: nothing is logged, held for abuse monitoring or used for training. No training on customer data. US; SCCs; DPA available.

Independent benchmark scores — composite indices for reasoning, coding, and math, plus individual eval scores where available.
Call GLM-5-Turbo through the Opper gateway with one API key. Opper is drop-in compatible with the OpenAI, Anthropic and Google AI SDKs.
GLM-5-Turbo is a premium model on Opper. Sign up needs no credit card: you get an API key straight away and the free models work in the playground and the API. Add a card to use premium models, pay-as-you-go with no minimum.
Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up Opper for you.
