GLM 4.7 Flash API Pricing

Where GLM 4.7 Flash sits on price
At $0.4 per million output tokens, GLM 4.7 Flash is a budget tier model — 5.5× cheaper than the median output price of $2.20, which puts it cheaper than 85% and pricier than 15% of the models we track. It sits 2th cheapest of the 15 Z.ai (GLM) models we track. Output costs 6.7× more than input here, so anything that makes the model write less — tighter instructions, structured output, lower max_tokens — moves the bill more than trimming the prompt.
Cached input is 83% cheaper. On an input-heavy workload you need roughly a 30% 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 Flash
These three workloads are the ones teams actually run on a budget-priced model — a $0.4/1M model is not bought for the same job as one ten times the price.
| Workload | Per request | Per month |
|---|---|---|
| High-volume classification — 200K requests/day (400 in / 20 out) Short output, huge volume: the input price dominates the bill. | $0 | $192 |
| Small app — 1K requests/day (500 in / 150 out) The baseline most side projects actually run at. | $0.0001 | $2.70 |
| Document pipeline — 10K docs/day (3K in / 500 out) Batch-friendly: no user waiting, so a ~50% batch discount usually applies. | $0.0004 | $114 |

Frequently asked questions
› How much does the GLM 4.7 Flash API cost?
GLM 4.7 Flash costs $0.06 per million input tokens and $0.4 per million output tokens, with cached input at $0.01 per million (83% cheaper). That works out to roughly 2,500,000 output tokens per dollar.
› What does the high-volume classification workload cost on GLM 4.7 Flash?
High-volume classification — 200K requests/day (400 in / 20 out) costs about $0 per request and $192 per month on GLM 4.7 Flash. Short output, huge volume: the input price dominates the bill.
› What does it cost to fill GLM 4.7 Flash's 203K context window?
Sending 203K of input in a single request costs $0.0122 at $0.06 per million tokens — before any output. With prompt caching that same fill drops to about $0.002 on repeat requests. This is why large context windows are cheap to advertise and expensive to actually use.
› Is GLM 4.7 Flash worth the price?
GLM 4.7 Flash is in the cheapest end of the market — cheaper than 85% of the models we track. At this price the question is not cost but capability: it is a good fit for classification, extraction, routing and bulk summarisation, and a poor fit for multi-step reasoning where a wrong answer costs more than the tokens saved.
