The supplied post pairs a free large coding model with Codex or Claude Code, agentic tool calls, and a fallback when rate limits appear.
Use this brief to set a policy. Verify current provider terms, access, and benchmarks separately.Choose the route that survives the work.
Estimate workload pressure for coding agents and make rate-limit fallback guidance explicit. This is a local assumptions model, not a live provider or benchmark feed.
Describe the workload
Route pressure combines tasks, tool calls, and the entered limit. Context is shown as a fit constraint. No provider availability or benchmark is inferred.
