Strengths

MoE architecture (~750B total, 40B active) — top open-weight model for long-horizon agentic coding (SWE-bench Pro 62.1, beating GPT-5.5)
1M-token context window (up to 128K output), made practical by IndexShare sparse attention — full-repository and book-length inputs in a single pass
Frontier-competitive on hard reasoning — GPQA Diamond 91.2 and AIME 2026 99.2, on par with leading Western models
Open-weight under MIT license — unrestricted commercial self-hosting, weights on HuggingFace and ModelScope
Cost-efficient at $0.98/M input and $3.08/M output — a fraction of comparable frontier models for long-horizon coding

Limitations

Text-only : no image or multimodal input
Headline benchmarks are self-reported by Z.ai; independent verification remains limited
Narrowly optimized for coding, agentic and reasoning tasks — weaker on broad conversational use (around #25 on Text Arena)
