GLM-4.5 is a foundational model of Zhipu’s GLM-4 line, designed around agentic tool use and general reasoning. It remains a solid, economical choice and anchors the family alongside its lightweight GLM-4.5 Air sibling.

Estimated from P50 latency × 200 output tokens — the absolute number depends on this assumption; the trend is what matters.

Availability

Availability

How often this model answers when we call it — measured across real API requests and live tests over the last 30 days. This is separate from quality: these numbers only tell you whether the model responds, not how good the answer is.

Technical details

Only live API calls and live-test requests count — internal probes and benchmark runs are excluded.

Calls with a custom API key (BYOK) are excluded: those failures are key-specific, not a sign of model downtime.

Failed calls are NOT included in quality scores — quality is measured on successful responses only. Availability and quality are independent signals.

Median response time (p50) across successful calls with a recorded duration. Outliers (very slow or very fast calls) pull the median less than the average.

GLM-4.5 adds tool use and JSON modes while maintaining performance

GLM-4.5 has expanded its capabilities with the addition of JSON output mode, tool calling functions, and reasoning features while preserving its core performance characteristics. The model continues to demonstrate strong multilingual capabilities, though specific benchmark scores are not available in this window for direct comparison. The addition of structured output support through JSON mode addresses a common need for developers building applications that require predictable response formats. Tool use functionality enables the model to interact with external functions and APIs, expanding its utility for agentic workflows and complex task execution. The reasoning capability suggests enhanced chain-of-thought processing for problems requiring multi-step logic. These additions position GLM-4.5 as a more versatile option for production use cases requiring structured outputs and external integrations. Users should note that while these new modes expand functionality, the underlying model performance appears stable. The combination of multilingual strength and newly added structured capabilities makes this update particularly relevant for developers building applications requiring both language diversity and programmatic reliability.

GLM-4.5: the established agentic GLM

GLM-4.5 is a foundational model of Zhipu’s GLM-4 line, designed around agentic tool use and general reasoning. It remains a solid, economical choice and anchors the family alongside its lightweight GLM-4.5 Air sibling.

z.ai publishes GLM-4.5 at $0.60 per 1M input tokens and $2.20 per 1M output tokens.

It advertises a 128K-token context window — ample for most documents and multi-turn agent sessions.

Architecture & training signals

GLM-4.5 is a core model of Zhipu AI’s GLM-4 line, noted for an agent- and tool-use-oriented design and for capable open-weight availability. It is a reasoning-capable chat model with tool-calling and JSON over an OpenAI-compatible endpoint. Like the rest of the GLM line, it returns a non-standard reasoning_content field alongside content in its OpenAI-compatible responses; integrations should read content for the final answer and treat reasoning_content as an optional trace.

Where it shines

  • Agentic tool use and function-calling workflows.
  • General-purpose reasoning at a value price.
  • A mature, well-understood member of the family.

Where it falls short

  • Newer GLM-4.6/4.7 and the GLM-5 generation improve on it.
  • No Tokonomix benchmark data yet; verify on your tasks.
  • Non-EU hosting.

Real-world use cases

  • Tool-using agents and function-calling pipelines.
  • General assistance, drafting and analysis at scale.
  • A low-cost, cross-family consensus proposer.

Tokonomix benchmark snapshot

GLM-4.5 is newly registered on Tokonomix and not yet activated, so we have not run it through our weekly intelligence test or speed benchmark. There are no Tokonomix scores to report yet — and we will not invent any.

When it goes live, it enters the same weekly harness as every other model: identical prompts, an independent cross-family judge, and reproducible latency and cost measurements. Until then, treat the pricing and capability notes on this page as the vendor-published starting point, not as measured Tokonomix results.

EU privacy & data residency

GLM-4.5 is built by Zhipu AI (z.ai), a China-headquartered lab, and is served from non-EU infrastructure. This is important to state plainly: routing a prompt to this model is not an EU-data-residency or GDPR-sovereign choice, and Tokonomix will never tag it as one.

If your use case requires data to stay within the EU, pick a model whose provider is EU-hosted (for example our OVH or Azure-EU routes) rather than a GLM model. Tokonomix keeps z.ai out of every EU-only / sovereign routing set by design. Use GLM where its capability or price is the priority and cross-border processing is acceptable for that workload.

Verdict & alternatives

GLM-4.5 is the established, economical GLM. For newer capability step up to GLM-4.6/4.7; when latency and cost dominate, GLM-4.5 Air or the free flash tiers. It is a reliable baseline within the GLM family.
