**GLM-5.2 vs GLM-5.1 pricing — they're identical on the official API, and 5.2 is actually cheaper on OpenRouter.**
### Z.AI Official Pricing (per 1M tokens)
| | Input | Cached Input | Output |
|--------------|--------|-------------|--------|
| **GLM-5.2** | $1.40 | $0.26 | $4.40 |
| **GLM-5.1** | $1.40 | $0.26 | $4.40 |
Same price across the board.
### OpenRouter Pricing (per 1M tokens)
| | Input | Cached Input | Output |
|--------------|----------|-------------|----------|
| **GLM-5.2** | $0.8071 | $0.1499 | $2.537 |
| **GLM-5.1** | $0.966 | $0.1794 | $3.036 |
On OpenRouter, 5.2 is ~17% cheaper on input and ~16% cheaper on output, likely due to more providers (28 vs 19) competing on price.
### Key capability difference
- **Context window**: GLM-5.2 has **1.05M tokens** vs GLM-5.1's **205K tokens** — 5x larger context
- **Latency**: 5.1 is slightly faster (2.13s p50 vs 2.89s p50)
- **Throughput**: roughly equal (~29-30 tok/s)
So GLM-5.2 gives you a much larger context window at the same or lower price. The only trade-off is slightly higher latency per request.
