GLM 4.5 supports a 131K token context window (131,072 tokens total). That translates to roughly 98,304 words in a single prompt. This is large enough to process entire codebases, research papers, or long conversation histories in one shot.

GLM 4.5 can generate up to 98K output tokens (98,304 tokens) per response. That is roughly 73,728 words. This is enough for generating complete code files, detailed reports, or long-form content in a single response.

GLM 4.5 supports function/tool calling, structured JSON output, extended reasoning/chain-of-thought, streaming responses. Function calling lets you integrate it with external APIs and tools programmatically. These capabilities determine which workflows and integrations the model can handle natively.

Yes, GLM 4.5 is an open-source model. You can download the weights, run it locally, fine-tune it for your use case, or deploy it on your own infrastructure. Many cloud providers also offer hosted versions if you prefer not to manage the infrastructure yourself. Self-hosting gives you full control over data privacy and eliminates per-token API costs.

GLM 4.5 was developed by Zhipu AI. It was released on July 25, 2025. You can access it through Zhipu AI's API or download the model weights directly. Check our provider page for all models from Zhipu AI and how they compare against each other.

Pick GLM 4.5 when you need a solid balance of cost and capability for everyday development tasks, content generation, and standard API integrations. If your task is straightforward text completion or classification, a cheaper model might give you 90% of the quality at a fraction of the price. Run a quick benchmark on your actual use case before committing.

You can access GLM 4.5 through Zhipu AI's API using standard HTTP requests or their official SDK. Most providers support OpenAI-compatible endpoints, so switching between models often requires changing just the model name in your API call. Streaming is supported for real-time token-by-token output. For production use, implement proper error handling, rate limiting, and cost monitoring.
