When to choose each
GLM-5.3
Best for
- Long-horizon agentic coding
- Self-hosted reasoning with permissive weights
Watch out for
- Text input only, and reasoning cannot be turned off: requests that disable thinking fail
- The licence requires a Z.ai security review before very large model-as-a-service operators use it commercially
MiMo-V2.6-Pro
Best for
- Long-horizon agent and coding work across modalities
- High-volume batch workloads
Watch out for
- The weights ship as two checkpoints (RL and MOPD), and Xiaomi does not say which one the API serves
- The mimo-v2.6-pro-ultraspeed id costs ten times as much and has no Batch API
