Compare Hermes, OpenClaw, and Codex

Use one well-defined task to compare three different assistant experiences. The goal is to learn which tool fits which job, not to declare one universal winner.

What you’re learning

These products combine different models, interfaces, tool permissions, and hosting choices. A fair comparison keeps the task and success criteria as similar as possible, then records where each product differs.

Work through it

  1. Pick a safe, repeatable task. For example: “In this disposable folder, read these three plain-text notes and produce a 5-bullet summary with filenames cited.” Make sample files yourself; do not use personal or sensitive documents.
  2. Write success criteria first. Decide what counts as correct: all three files represented, five bullets, filenames included, no files changed, and no unsupported claims. Keep the exact prompt and sample input the same.
  3. Run each tool. Use Hermes, OpenClaw, and Codex with comparable models where practical. Start with read-only permissions. If a product requires a different setup, record that as part of the comparison.
  4. Score and reflect. Give each result a 1–5 score for accuracy, instruction-following, transparency, ease of setup, speed, and cost. Note model/provider, permissions, and whether any data left your computer.

Example command / prompt

Task: Summarize the three sample notes in exactly 5 bullets.
Include the source filename for every bullet.
Do not edit or create files. State uncertainty clearly.
Keep this in mind. A local model, hosted API, and coding agent do not have identical privacy or tool behavior. Record the actual provider and enabled access for each run; do not assume that an “agent” processes everything locally.
Try thisRepeat the same task once with a deliberately improved prompt. Did clearer criteria help all three tools? Which one made its work easiest to verify?
