SemiAnalysis launches GDPx, an agent benchmark where the best model scores 12%

SemiAnalysis has released GDPx v1.0, a 206-task benchmark of long agentic work across 11 high-value domains such as chip design, cybersecurity, quant trading and recursive self-improvement. Claude Opus 5.5 leads at 12.0%, ahead of Gemini 4 Carbon at 10.9% and GPT-6 Astra at 9.6%.

SemiAnalysis has launched GDPx, a benchmark that tries to measure whether frontier models can do long, expert-level agentic work in the fields where the firm expects AI to earn the most money[1]. The headline result is how far there is to go: the best model on the board scores just 12.0%[2].

What's in it

Version 1.0 has 206 tasks across 11 domains, built with 14 specialised data partners[2]. The domains are chip design, cybersecurity, biology, finance, legal, quant trading, recursive self-improvement, hardware design, materials science, alignment and software engineering[1].

The selection is opinionated on purpose. Authors Max Kan, Andrew Megalaa and Dylan Patel argue that the first trillion dollars of AI revenue will be concentrated in sectors that can deploy frontier intelligence at high return, so a benchmark weighted by share of GDP or by occupation lists would track the wrong things[1]. They intentionally skipped industries like government, real estate and insurance[1].

How it's run

The default time limit is eight hours per task[1]. Models run in their own harness where one exists, such as Claude Code for Opus 5.5, Codex for GPT-6 Astra and Antigravity for Gemini 4 Carbon, and in OpenCode otherwise[1]. The headline score is pass@1 averaged over three attempts, with all domains weighted equally and each partner weighted equally within its domain[1][2].

SemiAnalysis says it approached more than 30 RL environment companies and put every partner through the same automated quality checks for consistency, cheating and unfair verifiers, backed by manual review of hundreds of trajectories[1]. It claims the same process flags nearly half of Terminal Bench 4.0's tasks as broken[1].

The leaderboard

Claude Opus 5.5 leads at 12.0% ($51.41 per task), followed by Gemini 4 Carbon at 10.9% ($16.29), GPT-6 Astra at 9.6% ($53.99) and Meta's Muse Wonder Full at 9.0%[2]. Further down, GPT 6.1 Sol scores 8.4% at $9.80 per task, while the budget options DeepSeek 4.1 Flash and GPT-6 Luna land at 5.4% and 5.1% for under a dollar a task[2]. Grok 4.7 sits at 3.9% and GLM 5.3 at 2.7%[2].

The caveats

Most of GDPx is private. Each partner open-sourced the rollouts for a single task, and the rest are held back to stop labs hill-climbing on them[3]. That protects the benchmark but means outsiders can't rerun it. With 206 tasks split 11 ways and scores this low, small gaps near the top shouldn't be over-read, and because models run in their own harnesses, the results measure the agent product as much as the model.

Why it matters

Benchmarks like SWE-bench and Terminal Bench are getting crowded at the top. GDPx resets the scale: on hours-long work in chip design, finance or RL research, even the best model earns an overall score of just 12.0%. It also shows the cost spread clearly, with Gemini 4 Carbon getting within about a point of Opus 5.5 for roughly a third of the price per task[2].

FAQ

Frequently asked questions.

01

What is GDPx?

A benchmark from research firm SemiAnalysis that measures general agentic capability. Version 1.0 has 206 tasks across 11 domains, built with 14 specialist data partners, and gives models up to eight hours per task by default.

02

Which domains does it cover?

Chip design, cybersecurity, biology, finance, legal, quant trading, recursive self-improvement, hardware design, materials science, alignment and software engineering. SemiAnalysis deliberately left out industries such as government, real estate and insurance.

03

Which model leads?

Claude Opus 5.5 at 12.0%, followed by Gemini 4 Carbon at 10.9%, GPT-6 Astra at 9.6% and Meta's Muse Wonder Full at 9.0%. The cheapest listed models, DeepSeek 4.1 Flash and GPT-6 Luna, score 5.4% and 5.1% for under a dollar per task.

04

How is it scored?

Each model runs in its native harness where one exists, such as Claude Code, Codex or Antigravity, and in OpenCode otherwise. The headline is pass@1 averaged over three attempts, every domain is weighted equally, and tasks use binary or partial grading depending on the domain.

05

Can anyone check the tasks?

Only partly. Each partner open-sourced the full rollouts for one task; the rest stay private so labs can't train toward them.
