## Use it with every other AI at once

MultiScreenAI (https://www.multiscreenai.com) puts GLM-5.3 on one screen next to ChatGPT, Claude, Gemini and 300+ models: one message goes to every panel, and a timed, blind test mode shows which answers best. Pro is free with a follow on X, and you use your own API keys.
AI agents and coding harnesses (Claude Code, Codex, Cursor, Gemini CLI) can ask GLM-5.3 and other models at once through the MCP server at https://www.multiscreenai.com/api/mcp/ai; setup: https://www.multiscreenai.com/mcp
