To pick a channel, add a provider field to the request body, for example "provider": { "channel": "direct" }. Valid values are direct / stable / economical; omit it to use the default channel.

Direct

Direct upstream connection — best when you need native behavior and the full context window.

GLM-5 Turbo API: A Fast Inference Tier for Agent Environments

GLM-5 Turbo is a fast inference model launched by Zhipu, designed for high-speed response and stable performance in agent-driven environments such as OpenClaw. It has been deeply optimized for real-world agent workflows involving long execution chains, with targeted improvements in complex instruction decomposition, tool use, planning and persistent execution, as well as overall stability in long-running tasks.

If your scenario is "the agent has to run many rounds of tool calls, and each round cannot be too slow," GLM-5 Turbo is usually a better fit than heavier inference tiers — it prioritizes speed while retaining the planning capability needed for long-chain execution.

SeaWhale AI provides GLM-5 Turbo through an OpenAI-compatible interface, with support for tool calling and streaming output.

Why Choose GLM-5 Turbo

Optimized for agent environments — Fast inference for agent-driven scenarios such as OpenClaw
Long execution chain stability — Less likely to go off track during multi-round tool calls
Complex instruction decomposition — Breaks ambiguous requirements into executable steps
131K context and output — Symmetric input/output, ample context for long tasks
Speed-first pricing tier — Cost control for high-frequency call scenarios

Core Capabilities

01 Agent-Driven Environments

GLM-5 Turbo is designed to run fast and stable in agent environments. In workflows requiring dozens or hundreds of tool calls, the cumulative effect of per-round latency is significant, and the Turbo tier is optimized specifically for this.

High-frequency tool call loops
Low per-round latency compounding into overall speedup
Execution core for agent frameworks

02 Complex Instruction Decomposition

Breaking a vague goal into a series of executable, concrete steps is key to whether an agent can complete the task. GLM-5 Turbo has been specially optimized for this stage.

Conversion from ambiguous requirements to execution plans
Identification of dependencies between steps
Verifiable intermediate goal setting

03 Planning and Persistent Execution

Maintaining memory of the original goal in long-chain tasks and not drifting off course due to intermediate detours is the core of "persistent execution" capability.

Goal consistency in long tasks
Path re-planning after intermediate failures
Continuous tracking of execution state

04 Overall Stability in Long Tasks

Compared with general-purpose models, GLM-5 Turbo is less prone to stability issues such as format corruption, tool parameter errors, and repeated loops in long-running tasks.

Accuracy of tool parameter construction
Consistency of output format
Avoidance of ineffective loops

How to Use the GLM-5 Turbo API

1. Create a SeaWhale AI API key Generate a key in the console and add credits.

2. Use it for high-frequency loops The value of GLM-5 Turbo lies in the cumulative effect of multi-round calls. For single deep reasoning tasks, use GLM-5 or GLM-5.2.

3. Call the API

FAQ

What's the difference between Turbo and the standard version? Turbo prioritizes speed and long-chain execution stability, while the standard GLM-5 prioritizes deep reasoning and system design capability. Which one to choose depends on whether your bottleneck is latency or reasoning depth.

What exactly does "agent-driven environment" mean? It refers to runtime environments such as OpenClaw where agents take the lead and require heavy tool calling and autonomous decision-making. GLM-5 Turbo has been deeply optimized for such scenarios.

What are the context and output limits? 131,072 tokens of context, with the same 131,072-token output limit.

Is it suitable for multi-agent architectures? Yes. The speed advantage is further amplified when multiple agent instances run in parallel.

Will it drift off course in long tasks? GLM-5 Turbo has been specially optimized for planning and persistent execution, making it more stable than general-purpose models at maintaining goal consistency over long chains.

Can it be mixed with other GLM models? Yes, and it's recommended. Use Turbo for high-frequency execution loops, and switch to GLM-5 or GLM-5.2 when you hit nodes that require deep reasoning.
