GLM-4.5 Flash vs GLM-5

💰 Budget priority

GLM-4.5 Flash is cheaper on output pricing. For output-heavy workloads (code generation, content creation), the price gap materially affects monthly cost.

📚 Long documents / large context

GLM-5 has the larger context window (128K). Pick it for large codebases, long-form novels, or legal contracts.

💡 Hands-on recommendation

Sign up for Nodebyt to call both models with a single API key — just swap the `model` parameter. A $2 top-up is more than enough for side-by-side evaluation.
