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.
DroidoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
GPT-5.4 Mini runs on the routes below. Route only to EU providers when your data has to stay in Europe. One route also sells flex and priority processing: the same model at another price, picked per request with service_tier. How service tiers work.
GPT-5.4 Mini is OpenAI's strongest small model, improving over GPT-5 Mini in coding and reasoning while running more than 2x faster, with a 400k context window.
Step-by-step setup for running Droid on each of these models through Opper.
Anthropic's terminal coding agent. Run it on any model on Opper, not just Claude.
opper launch claude
OpenAI's open-source coding CLI. Run it on any model on Opper.
opper launch codex
DeepSeek's open-source coding agent. Add Opper as a custom provider to run it on any model, not just DeepSeek's.
