1routers
Explore which models—Claude, Gemini, Grok, DeepSeek, and more—you can use in Codex Desktop and when each is useful.
A model is a task decision
There is no single best model for every repository and every stage of development. Strong planning, fast iteration, long-context review, and economical automation can point to different choices.
GPT
A broad fit for agentic coding, tool use, and general software work.
Claude
Useful for careful code reading, extended context, and structured explanation.
Gemini
A strong option for multimodal context and broad technical synthesis.
Grok
An alternative model family for fast, exploratory technical work.
DeepSeek
A cost-conscious option for coding, reasoning, and repeatable tasks.
Availability is explicit
The model market in 1routers shows current availability, compatible tiers, pricing, and route health. A model appearing in editorial content is not a promise that every version or route is always active.
Model names belong to their respective providers. 1routers is an independent routing product and is not endorsed by those providers.
Choose by work, not by logo
Start from the job: repository exploration, a focused patch, architecture review, or high-volume automation. Then choose the model and tier that provide the right balance for that work.
Start with a beginner task
Complete a first task, learn to switch model families, and then control costs. Each guide begins with a practical beginner question.
