About the model
What is GLM 4.7?
GLM 4.7 is a frontier-scale large language model from Z.ai, designed as a general-purpose assistant with particular strengths in software development and complex reasoning tasks. It is widely used for code generation, debugging, and agent-style tools that require reliable multi-step execution, as well as for advanced chat, analysis, and content creation workloads across long contexts. It belongs to Z.ai’s GLM model family as a successor to earlier GLM-4.x releases and is provided as an open-source Apache 2.0 MoE-based model.

Architecture & Integration
Why Build on LLM.API?
One unified API. Every major model. Built-in reliability, cost control, and observability.
-
Unified AI Routing
Intelligently route each request across models and providers based on latency, cost, and quality. One API, dynamic routing rules, no client rewrites.
One endpoint, any model -
Cost-Aware Controls
Enforce per-project and per-model budgets, caps, and policies at the gateway. Optimize spend automatically without touching your application logic.
Control cost per call -
Resilient Fallback Flows
Automatically fail over to backup models or providers on errors, timeouts, or rate limits. Keep your AI features online without custom retry logic.
No single point of failure -
End-to-End Observability
Trace every request across models with metrics, logs, and timelines. Debug latency, failures, and behavior from a single observability layer.
See every token hop -
Task-Level Orchestration
Define higher-level tasks—like classification or extraction—then plug in any compatible model. Swap models without rewriting business logic.
Code to tasks, not models -
High-Throughput Batch
Send massive batches through one optimized pipeline with concurrency, backoff, and retries built in. Maximize throughput while respecting provider limits.
Millions of calls, one pipe
