Droid is Factory's coding agent, running in the terminal, in IDEs, and in Factory's desktop app. It plans and executes real engineering tasks, and its bring-your-own-key support takes custom models on any OpenAI-compatible or Anthropic-compatible endpoint, on every plan. Add Opper as a custom model and you get one key to 700+ models, with usage billed straight through your Opper account.

GLM-5.3-Flash runs on the routes below. Route only to EU providers when your data has to stay in Europe. Some routes also sell flex and priority processing: the same model at another price, picked per request with service_tier. How service tiers work.
GLM-5.3-Flash by Z.ai is a natively multimodal 320B MoE with 18B active parameters, hybrid sparse and linear attention, a 1M-token context, and MIT open weights for coding and agent work.
