## Specs

- Context length: 1048576 tokens
- Max output: 131072 tokens
- Modalities: text
- Released: 2026-08-18

## Providers

- **z-ai** — ctx 1048576, input $0.45/M, output $2.00/M

## Verdict

GLM 5.3 batch is a cost-optimized variant of Zhipu AI's latest model, trading response speed for aggressive pricing. At $0.45 per million input tokens, it undercuts most frontier models by 70-80% while maintaining the full 1M token context window. Best for high-volume document processing, overnight analysis jobs, and teams that can tolerate 10-30 minute latencies. If you need real-time responses, use the standard GLM 5.3 endpoint instead.
