| Provider | Context window (tokens) | Serving and capacity |
|---|---|---|
| DeepInfra1 | 1M | Promotional standard pricing; Flex is a separate tier. |
| Novita AI2 | 1M | GLM-5.3 lists 1M context, 128K max output and fp8 on Novita. |
| Together AI3 | 1M | GLM-5.3 supports serverless and dedicated deployment; serverless capacity is best-effort. |
| Fireworks AI4 | 1040k | GLM-5.3 supports serverless, on-demand deployment and LoRA fine-tuning. Account-wide quotas remain separate from GPU capacity. |
Routing performance is reported separately from direct-provider prices; the standard Fireworks route excludes Fireworks Fast.

Options, strengths and limitations
Options, strengths and limitations
DeepInfra
A promotional-cost GLM option with fp4 serving and published zero data retention.
- Input / 1M tokens
- $0.563
- Output / 1M tokens
- $2.50
- Cached input / 1M tokens
- $0.125
Strengths
- DeepInfra lists fp4 serving and zero data retention at the lowest direct-provider price in this shortlist.
Limitations
- The displayed $0.563 input rate is rounded promotional pricing; Flex is separate, and fp4 differs from Novita’s listed fp8.
Novita AI
An fp8 GLM endpoint for applications that need the listed long-context and output limits.
- Input / 1M tokens
- $1.40
- Output / 1M tokens
- $4.40
- Cached input / 1M tokens
- $0.26
Strengths
- Novita lists fp8, 1M context and a 128K output cap for its GLM-5.3 API.
Limitations
- Its $0.01840 request estimate exceeds DeepInfra’s $0.00813; the 128K output cap also constrains very long generations.
Together AI
A GLM deployment option with selectable reasoning effort on serverless or dedicated infrastructure.
- Input / 1M tokens
- $1.40
- Output / 1M tokens
- $4.40
- Cached input / 1M tokens
- $0.26
Strengths
- Together offers low, high and max reasoning settings with a listed 1M context, on serverless and dedicated infrastructure.
Limitations
- The $0.01840 request estimate is above DeepInfra’s promotion; serverless capacity is best-effort rather than committed throughput.
Fireworks AI
A GLM service for LoRA customization with serverless and on-demand deployment choices.
- Input / 1M tokens
- $1.40
- Output / 1M tokens
- $4.40
- Cached input / 1M tokens
- $0.26
Strengths
- Fireworks lists a 1040k usable context and LoRA fine-tuning for GLM-5.3, with serverless and on-demand deployment.
Limitations
- Its $0.01840 request estimate is not a price saving over Novita or Together; requested output must fit the remaining context after the prompt.
Methodology
Methodology and sources
GLM-5.3 speed and latency use OpenRouter’s Standard / all-reasoning / P50 provider rows; Fireworks Fast is excluded. These are routed results, not direct API measurements, and route latency is not TTFT. Prices are the vendors’ direct uncached synchronous rates: DeepInfra’s standard promotion is separate from Flex and from OpenRouter route discounts.
The GLM cost chart applies those direct rates to 10,000 input and 1,000 billed output tokens, including reasoning. Cards follow that uncached cost, not an accuracy ranking; matched prices may use different serving precision or capacity. Tax, retries, discounts and negotiated deployments are outside the estimate. Novita AI publishes the comparison from public data; no private GLM workload was run.
