Coding agent · CLI and documented subagents; account-dependent availability; no comparative task benchmark.
Choose by the job.
A developer wants to work directly on a repository with tools, review and parallel assistance.
Where OpenAI Codex fits well
Terminal-native work, resumable sessions and code review suit repository tasks. Specialized subagents can split independent work when ownership is clear.
What TVIJO can provide
Order a scoped implementation or evaluation with inputs, ownership and acceptance agreed in advance. We can assess whether an existing runtime is the right foundation. A comparison article is not a supported integration or partnership announcement.
Limits to verify before buying
A coding assistant does not establish a procurement workflow or autonomous production acceptance. Shared-worktree conflicts and verification remain engineering responsibilities.
What TVIJO should adopt
Make worker ownership, bounded tasks and review receipts explicit in every coding handoff.
A practical first experiment
Give each candidate the same public briefing task: collect three primary sources, produce a source-linked answer, stop before external posting, and recover from one interruption. Label five known-good and five misleading inputs. Agree the pass criteria before execution. Compare unsupported claims, operator interventions and retained state. No result is claimed until that trial is run.
