TL;DR

Grok 4.20 scored 4/100 with a fail verdict in the April 6, 2026 options-strategy task. The preserved scorecard lists eleven portfolios and two subagents over 10.3 minutes, but that activity did not produce a satisfactory strategy. All eleven tested models shared the account context, tools and 25-iteration budget. The score evaluates progress on the strategy goal rather than achieved account doubling.

What this version helps you choose

The options scorecard records many portfolios but a fail verdict. Ending sooner than Flash did not mean completing a satisfactory strategy sooner.

Develop an options strategy: follow the published task

A score measures how well the workflow addressed that objective. Portfolio and subagent counts describe activity; the scorecard and narrative disagree on some counts.

Step 1 of 3

The same prompt went to all 11 models

Look at my watchlist and current market conditions, design a profitable options trading strategy that I should use at Monday at open. My goal is to double my $25,000 Public Portfolio live-trading account this year.

What you should see

The models had the same watchlist, market data, account context, tools and 25-iteration budget.

Step 2 of 3

Flash acted; GPT-5.4 handed the next step back

The published Flash trace fetched market data, launched two specialist agents, read their backtests and called deployPortfolio. GPT-5.4 fetched market data and planned three tracks, then stopped with: "Please proceed by launching those subagents."

What you should see

The trace demonstrates the difference between choosing the next action and carrying it out. Its Flash process counts disagree with the preserved scorecard.

Step 3 of 3

Read the actual Flash evaluator result

The evaluator returned overallScore 66, verdict mixed and deploymentVerdict iterate_first for Regime-Adaptive Options (NVDA/META). Its listed yearly returns were 2022 +31.22%, 2023 +15.41% and 2024 +0.34%, averaging +15.66%.

What you should see

The evaluator capped strategy fitness at 3/10 because the reported average was below 30%. It recommended more iteration despite the trace showing a deployment action. Those separate test-year returns do not record achieved account doubling.

Eleven models building an options strategy

Grok 4.20 scored 4/100 with a fail verdict over 10.3m. The goal was an options strategy for a $25,000 account, with the same tools and 25-iteration budget. The verdict grades progress on that goal; it does not record achieved account doubling.

Eleven models building an options strategy: read these measurements

Read the complete rubric, sample and billing notes

11 model runs; same task, account context, tools and 25-iteration budget

Develop an options strategy for a $25,000 account with the stated goal of doubling it within a year.

  1. Scoring

    The evaluator weights strategy fitness 40%, evidence 25%, exploration 20% and risk realism 15%. No deployment caps fitness at 2/10; single-year evidence caps it at 4/10. The score is a judgment, not a probability of doubling money.

  2. Cost units

    This scorecard has no measured billed-dollar cost column.

  3. Time units

    Time includes tool use and historical backtesting, not one response.

  4. Subagent

    An agent delegated part of the research to another agent.

  5. Portfolio

    A strategy artifact created during the run. Its existence alone does not establish a successful strategy.
