Frequently Asked Questions
How much does GLM-5.3 cost?
GLM-5.3 costs $1.40 per 1M input tokens and $4.40 per 1M output tokens via Z.AI; all 2 providers listing it charge the same rate.
What does GLM-5.3 cost for 10M input and 2M output tokens?
At Z.AI's rates, 10M input tokens and 2M output tokens cost about $22.80: $14.00 for input and $8.80 for output. Input is prompts and context, output is what the model writes back; a workload that generates more than it reads shifts the cost toward the output rate of $4.40 per 1M tokens.
Which providers offer GLM-5.3?
2 providers list GLM-5.3: Z.AI ($1.40 in / $4.40 out) and Novita ($1.40 in / $4.40 out). Rates are per 1M tokens in USD, cheapest input rate first.
What is GLM-5.3's context window?
GLM-5.3 accepts up to 1M tokens of input per request and returns up to 131K tokens per response. The context window is the prompt plus any documents, conversation history and tool results sent with it; every token in it is billed at the input rate.
What inputs and outputs does GLM-5.3 support?
GLM-5.3 accepts text as input and produces text. Its listed capabilities are function calling and structured output.
How does GLM-5.3 compare with GLM-5.1?
GLM-5.3 costs $1.40 per 1M input tokens against GLM-5.1's $1.38, 1x more expensive ($4.40 vs $4.40 per 1M output tokens). The context window is 1M tokens against 205K.
What are cheaper alternatives to GLM-5.3?
Models from other creators with a lower input rate and at least GLM-5.3's 1M-token context window: Gemini 2.5 Pro at $1.25 per 1M input tokens (1M context), Muse Spark 1.1 at $1.25 per 1M input tokens (1M context) and Muse Spark 1.2 at $1.25 per 1M input tokens (1M context). Rates are the cheapest listed provider for each; whether the quality holds for a given task is a separate question.
