o3 competitor: GLM 4.5 by Zhipu AI
- hybrid reasoning model (on by default)
- trained on 15T tokens
- 128k context, 96k output tokens
- $0.11 / 1M tokens
- MoE: 355B A32B and 106B A12B

Benchmark details:
- tool calling: 90.6% success rate vs Sonnet’s 89.5% vs Kimi K2 86.2%
- coding: 40.4% win rate vs Sonnet, 53.9% vs Kimi K2, 80.8% vs Qwen3 Coder

Zhipu AI has also released their entire post-training infrastructure: https://github.com/THUDM/slime 

Slight correction to the post:
- it was not just 15T tokens
- it was 23.1T tokens total! 

For those wondering how to get GLM 4.5 cheaply: you need to use their Mainland China API.

Update: Zhipu AI says the initial benchmark I posted are not up-to-date, so here is the updated version.

Note that I found the original benchmark comparison on their bigmodel documentation.
