Z.ai запустила API GLM-5.3 для программирования и долгосрочных агентных задач

GLM 5.3 is Z.ai's coding and agentic model, released August 14, 2026, built on the same 743B-parameter base as GLM 5.2 with every gain coming from scaled post-training rather than a new architecture. Its headline results are large: Terminal-Bench 3.0 jumps from 4.6 to 28.3, DeepSWE v1.1 from 46.2 to 66.9, and CyberGym reaches 84.5%, the top score in Z.ai's launch chart. Nearly every benchmark is vendor-reported by Z.ai. Artificial Analysis independently scores it 60 on its Intelligence Index at high reasoning effort, ranking it 9th of 186 models. The API opened on August 18, 2026 at $1.40 input and $4.40 output per million tokens, matching GLM 5.2. The GLM Coding Plan starts at $18 a month. [...] ## How much GLM 5.3 costs and how to access it GLM 5.3 is available two ways: a per-token API and a subscription Coding Plan. Both are summarized below. _Table 3: GLM 5.3 access and pricing (as of August 2026)_ | Access route | What it is | Cost | --- | Per-token API | Direct API

GLM 5.3 GLM-5.3 is a large-scale reasoning model from Z.ai, built for complex software engineering and long-horizon agent tasks. It supports text input and output with a 1M-token context window, and improves on GLM-5.2 in coding and in the balance between performance and token efficiency. Reasoning is always on and cannot be disabled. Reasoning efforts `low`, `high`, and `max` are supported; `max` is the default.

FAQ ## Frequently asked questions GLM 5.3 is Z.ai's flagship large language model, released on August 14, 2026, optimized for complex software engineering, long-horizon tasks, and cybersecurity. It improves over GLM 5.2 by 50% in coding performance through scaled post-training, not architecture changes, and supports function calling, web search, and structured output. GLM 5.3 is open weights under the Z.AI License, allowing use, modification, and redistribution with attribution. The weights were released two weeks after launch following a safety review. It is not free to run — pricing is $1.75 per 1M input tokens and $5.50 per 1M output tokens on Venice. [...] Ask anything...

Today, Z.ai GLM-5.3, described as "Built to Code. Ready for Cyber Defense," is available on Bitdeer AI Model Studio, bringing one of the strongest open-weight coding and agentic models to our serverless inference platform, built for secure, scalable enterprise AI. You can start calling it through a single API today, without provisioning or managing the underlying GPU infrastructure. ## What Is GLM-5.3? [...] That approach concentrated gains in two areas: long-horizon coding and cybersecurity. Z.ai reports GLM-5.3 is its most powerful open-weights coding model to date, with the largest jumps on the hardest, most agentic benchmarks, and says the model's vulnerability-discovery ability advanced further than the team expected, with GLM-5.3 beginning to reason across multiple stages of an exploit and form coherent plans for complete exploitation chains. ## Key Specifications [...] Bitdeer AI Cloud # GLM-5.3 now live on Bitdeer AI Model Studio, built to Code and Ready for Cyber Defense #
