GLM 4.7 API Pricing

Where GLM 4.7 sits on price
At $1.75 per million output tokens, GLM 4.7 is a mid tier model — 1.2× cheaper than the median output price of $2.08, which puts it cheaper than 57% and pricier than 43% of the models we track. It sits 7th cheapest of the 17 Z.ai (GLM) models we track. Output costs 4.4× input, the usual spread — trim both, starting with the answer length.
Cached input is 80% cheaper. On an input-heavy workload you need roughly a 31% cache-hit rate to take 25% off the input line — reachable for chatbots and agents that resend the same system prompt and history.
What real workloads cost on GLM 4.7
These three workloads are the ones teams actually run on a mid-priced model — a $1.75/1M model is not bought for the same job as one ten times the price.
| Workload | Per request | Per month |
|---|---|---|
| Support chatbot — 500 conversations/day (5K in / 1.4K out) Conversation history re-sent each turn — the classic prompt-caching win. | $0.0044 | $66.75 |
| Document pipeline — 10K docs/day (3K in / 500 out) Batch-friendly: no user waiting, so a ~50% batch discount usually applies. | $0.0021 | $623 |
| Small app — 1K requests/day (500 in / 150 out) The baseline most side projects actually run at. | $0.0005 | $13.88 |

› What does the support chatbot workload cost on GLM 4.7?
Support chatbot — 500 conversations/day (5K in / 1.4K out) costs about $0.0044 per request and $66.75 per month on GLM 4.7. Conversation history re-sent each turn — the classic prompt-caching win.
› What does it cost to fill GLM 4.7's 205K context window?
Sending 205K of input in a single request costs $0.0819 at $0.4 per million tokens — before any output. With prompt caching that same fill drops to about $0.0164 on repeat requests. This is why large context windows are cheap to advertise and expensive to actually use.
› Is GLM 4.7 worth the price?
GLM 4.7 sits in the middle of the market (7 of 17 by price within Z.ai (GLM)). The honest test is a routing experiment: send the same 200 real requests to this model and to a tier below, and compare failure rate against the price gap — most teams find a majority of traffic never needed the pricier model.
