Estimate your cost
Set your usage. Your estimate updates as you type.
Example: 6,000 input tokens for 10 pages, plus a 500-token summary. Page lengths vary; adjust the numbers below.
One run sends your input to the model once and receives an answer. Tokens are pieces of text: input is what you send, output is the answer you receive.

How this estimate works
Estimates exclude taxes, tools, cache storage/writes, free allowances and custom discounts. Image estimates cover output only, not prompt or reference-image charges. Quality modes differ by model. Unlisted settings are not treated as free.

Quick take
Mistral Small 4
Mistral's lower-cost open model that combines normal instruction following, reasoning, coding, vision, and agent tools in one endpoint.
Best for
- Cost-sensitive production assistants
- Coding and tool use on one flexible model
- Self-hosted text-and-image applications
Watch out for
Sparse activation lowers inference work but does not make the full 119B checkpoint small. Size hardware around the actual quantization and context you plan to serve.
GLM-5.3
Z.ai's open-weight long-context reasoning model for coding, tools, and agentic work across self-hosted and managed routes.
Best for
- Long-context coding agents
- Open-weight enterprise experiments
- Teams that want several inference-provider choices
Watch out for
Compare the exact checkpoint and host, not just the model name. Context, maximum output, speed, price, logging, and reasoning controls can all change by route.
Compare the published facts
Mistral Small 4 vs GLM-5.3
Values use each provider's own published units and limits. A blank means the provider did not publish a directly comparable value in the sources reviewed.

How to choose
Compare the job, not the hype.
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
Mistral Small 4
Mistral's commercial terms exclude model training by default except when a customer opts in or uses designated Labs or preview models. Self-hosting keeps inference data under the operator's controls; hosted API retention is generally 30 days unless zero data retention is enabled.
Provider and API links
GLM-5.3
Self-hosted weights keep prompts inside infrastructure you control. QwenCloud says it does not retain API inputs or outputs for training; OpenRouter and other providers apply their own route policies.

What is the main difference between Mistral Small 4 and GLM-5.3?
Mistral Small 4: Mistral's lower-cost open model that combines normal instruction following, reasoning, coding, vision, and agent tools in one endpoint. GLM-5.3: Z.ai's open-weight long-context reasoning model for coding, tools, and agentic work across self-hosted and managed routes.
Should I choose Mistral Small 4 or GLM-5.3?
Consider Mistral Small 4 when your priority is Cost-sensitive production assistants. Consider GLM-5.3 when your priority is Long-context coding agents. Test both with your own data and provider route before committing.
Is this Mistral Small 4 vs GLM-5.3 comparison based on Cody benchmarks?
No. This comparison aligns provider-published facts for the Text & reasoning category. It does not claim a universal winner or combine incompatible third-party benchmark scores.
