The tutorial includes token and cost accounting for measurable demos.", "body_md": "We build a practical GLM-5.2 workflow using its hosted, OpenAI-compatible API instead of running the model locally. We set up multiple providers, load the API key securely, and create a reusable chat wrapper. We then test thinking-effort control, streamed reasoning, function calling, a tool-using agent, structured JSON output, and long-context retrieval. We close with token and cost accounting so every demo stays measurable.\n\nThe post [GLM-5.2 OpenAI-Compatible API: A Hands-On Guide to Reasoning Effort, Function Calling, and Long-Context Retrieval](https://www.marktechpost.com/2026/06/22/glm-5-2-openai-compatible-api-a-hands-on-guide-to-reasoning-effort-function-calling-and-long-context-retrieval/) appeared first on [MarkTechPost](https://www.marktechpost.com).", "url": "https://wpnews.pro/news/glm-5-2-openai-compatible-api-a-hands-on-guide-to-reasoning-effort-function-and", "canonical_source": "https://www.marktechpost.com/2026/06/22/glm-5-2-openai-compatible-api-a-hands-on-guide-to-reasoning-effort-function-calling-and-long-context-retrieval/", "published_at": "2026-06-23 06:35:05+00:00", "updated_at": "2026-06-24 00:26:16.526512+00:00", "lang": "en", "topics": ["large-language-models", "ai-tools", "ai-products", "developer-tools", "natural-language-processing"], "entities": ["GLM-5.2", "OpenAI", "MarkTechPost"], "alternates": {"html": "https://wpnews.pro/news/glm-5-2-openai-compatible-api-a-hands-on-guide-to-reasoning-effort-function-and", "markdown": "https://wpnews.pro/news/glm-5-2-openai-compatible-api-a-hands-on-guide-to-reasoning-effort-function-and.md", "text": "https://wpnews.pro/news/glm-5-2-openai-compatible-api-a-hands-on-guide-to-reasoning-effort-function-and.txt", "jsonld": "https://wpnews.pro/news/glm-5-2-openai-compatible-api-a-hands-on-guide-to-reasoning-effort-function-and.jsonld"}}
