Questions about GLM 5.3 Flash
Something else? Ask support or read the docs.
- Is GLM 5.3 Flash really free on FreeFlow?
- Yes. GLM 5.3 Flash is one of FreeFlow's unlimited models: no cap, no credit used, no bill. A small sponsor card in the Harness pays for it.
- Are there limits on GLM 5.3 Flash?
- There's no weekly credit or request cap. FreeFlow may slow requests briefly when the model provider is busy.
- What can I use when I want a stronger model?
- Switch to Opus 5.5, GPT 6.1 Sol, Kimi K3 or another credit model from the picker, mid-task if you like, using your $50 weekly credit.
- Can I use GLM 5.3 Flash in my own app or editor?
- FreeFlow's models run inside the FreeFlow Harness, which works on any project folder alongside whatever editor you use. Requests from other software aren't supported, because the Harness's ads pay for the tokens.
