Add Model

Add a New Model to the Eval Runner

Follow these steps whenever the user asks to add a new AI model to the eval suite.

Step 0: Gather Information

Determine the following (ask the user if not provided):

1. Model identifier - the OpenRouter-style name, e.g. anthropic/claude-opus-4.6. If the user gives a marketing name or URL, look up the OpenRouter model id.
2. Formatted name - human-readable, e.g. Claude 4.6 Opus.
3. Provider family & version - needed to find older siblings (e.g. claude-opus-4.5 is the predecessor of claude-opus-4.6).
4. apiKind - only needed for OpenAI Codex/Responses-API models; set to "responses". Omit for all other models.

If you're unsure, check how the closest existing model in the same family is configured in runner/models/index.ts and match it.

Step 1: Add the Model to runner/models/index.ts

Open runner/models/index.ts and add a new entry to the ALL_MODELS array. Place it next to its family siblings, respecting the existing grouping comments.

Template:

{
  name: "<provider>/<model-id>",
  formattedName: "<Human Name>",
  // apiKind: "responses",  // only for OpenAI Codex / Responses-API models
},

Step 2: Update the Manual Evals Workflow

Open .github/workflows/manual_evals.yml and replace the entire matrix.model list with only the new model. This workflow exists solely to collect baseline data for newly added models, so it should only ever contain the latest addition.

matrix:
  model:
    - "<provider>/<model-id>"

Step 3: Typecheck

Run bun run typecheck to verify no type errors were introduced.

Step 4: Smoke Test the New Model Locally

Before committing, run a quick local sanity check with one or two simple evals to confirm the model ID is valid, the API key works, and results are being produced. Use the simplest fundamentals evals:

MODELS=<new-model-name> TEST_FILTER="000-fundamentals/000" bun run local:run

If that passes, optionally run one more:

MODELS=<new-model-name> TEST_FILTER="000-fundamentals/001" bun run local:run

What to look for:

• No authentication or "model not found" errors
• The run completes and produces a score (even a low score is fine - we just want to confirm it runs)
• If it fails with an API/auth error, stop and fix the model ID or check the .env file before proceeding

Only proceed to the next step once at least one eval completes successfully.

Step 5: Commit and Push

Create a descriptive commit message and push to main:

git add runner/models/index.ts .github/workflows/manual_evals.yml
git commit -m "add <model-name>; demote older <family> versions"
git push origin main

Step 6: Trigger Manual Eval Runs for Baseline Data

Use the GitHub CLI to dispatch the manual eval workflow 3 times (to get a statistically meaningful baseline):

gh workflow run manual_evals.yml --ref main

Run this command 3 times, waiting ~5 seconds between dispatches to avoid collisions.

Step 7: Monitor the Runs Until Completion

You MUST poll until all 3 runs reach a terminal state (completed/failed/cancelled). Do not stop monitoring early or hand back to the user while runs are still in progress.

Poll every ~2 minutes using:

gh run list --workflow=manual_evals.yml --limit=6

Runs typically take 20-30 minutes. Keep checking until all show completed. If a run fails, immediately investigate:

gh run view <run-id> --log-failed

Report the final pass/fail status for each run to the user once all 3 are done.

Summary Checklist

• Model added to ALL_MODELS in runner/models/index.ts
• .github/workflows/manual_evals.yml matrix replaced with only the new model
• bun run typecheck passes
• Smoke test: at least one eval completes successfully locally
• Changes committed and pushed to main
• Manual eval workflow dispatched 3 times
• All 3 runs monitored to completion
