RusorAgentAI includes four frontier models in every paid package. Auto routing is fine for mixed chats. Pin a model when you know the job.
Claude Opus 4.6
Best default for multi-file refactors, tricky business rules and “make this production-ready.” It holds constraints across a long session.
GPT-5
Fast, versatile, strong at product language and general coding. Use it for first drafts, APIs with obvious shapes, and iteration when you already have a skeleton.
GLM 5.1
Reach for GLM when the repo or the users are multilingual, or when you want a second opinion on code the other models wrote.
Gemini 2.5 Pro
Long context and multimodal. Feed it docs, screenshots, PDFs and large files. Excellent for “read this design and implement the UI.”
