GLM-5.3 Flash Uncensored is live
GLM-5.3 Flash Uncensored is now our lowest-cost model. It is Z.ai's fast model with its refusal behavior removed, priced for work you run in volume.
What it is good at
At $0.30 per 1M input tokens, it is cheap enough to leave on for background jobs: labeling, data generation, summaries, and the boring steps of an agent run. Reasoning effort goes from low to max, and max is the default, so set it lower when speed matters more than depth.
