One-sentence summary
Among the three open-weight models, Mistral Large 4 leads the western camp at about 1.05T total params on coding/cybersecurity benchmarks, while GLM-5.3 and DeepSeek V4.1 score higher on the aggregate intelligence index; choose between self-hosting, commercial licensing and scenario benchmarks.
Models
- Mistral Large 4 (Le Chonk): France's Mistral AI opened weights on October 29, 2026; natively multimodal MoE.
- DeepSeek V4.1 (Flash): China's DeepSeek open-weight model, cited as a coding-agent benchmark reference.
- GLM-5.3: China's Zhipu open-weight model, near-tied with Mistral on the AA Coding Agent Index.

Key Differences
- Region and aggregate ability: Mistral's v5 index of 26 is the highest among western open weights, but the firm concedes Chinese models (GLM, DeepSeek, Kimi) score higher overall.
- Coding efficiency: Mistral uses 47% fewer tokens than GLM-5.3 on average coding-agent tasks.
- Commercial terms: Mistral requires a separate commercial license for MaaS operators; GLM/DeepSeek terms must be checked per their licenses.
Buying Guidance
- Western compliance, self-hosting, coding/cybersecurity: evaluate Mistral Large 4 first.
- Aggregate intelligence and Chinese-language use: evaluate GLM-5.3 and DeepSeek V4.1.
- MaaS resale: verify Mistral's commercial license terms before launch.
