Opus 5 is a shocking step up from Fable 5 and 5.6 Sol for spreadsheets
Almost couldn’t believe our evals at first
A step function increase in intelligence, while as efficient as Sol
Feels like another Opus 4.5 moment for knowledge work

I challenged the MSFT Excel World Champion to a battle.
AI beat humans at Chess, then Go. But those are games
We built an agent to surpass humans on the most important app in the history of work
Meet Shortcut: The Excel AI Agent
Comment SATYA and I'll send you free credits

@nicochristie just beat the Excel world champion at financial modeling by using @tryshortcutai
18 months ago, we demoed to investors an agent that's 2x SOTA on OSWorld, and "superhuman" on its Spreadsheet category, scoring ~80% when every other agent was <20%
At the time our agent was able to create pivot tables and that was considered impressive
We have truly gone a long way, super proud of the team🔥

What a week! The first GPT model worth being served by default in Shortcut.
Let's benchmark Grok 4.5 tomorrow! 😁
we evaluated GPT 5.6-Sol against Fable and Opus using the Shortcut production harness on our own internal set of benchmarks, results were very surprising
ShortcutBench V1: swiss-army knife spreadsheet tasks
ShortcutBench V2: gnarly, tough, long spreadsheet tasks
Sol costs half as much as opus and had similar if not higher accuracy. It also took way less turns and was much faster.
Historically, we never served GPT models as default because they are significantly worse at formatting (trust-breaking) than Opus class models. This is also no longer true in our taste tests, although fable is still the best at formatting
well done @OpenAI

Tianhang finally on twitter. He was a founding member at Qwen and head of RL at 01.ai
There's so much discussions about models from the Chinese labs, but very few people on twitter actually worked there and in the US now

Tianhang is finally on twitter
He was formerly a founding team member and head of RL at Qwen, and leads model training here at FRL / shortcut
He will be posting more on twitter now
Probably the most cracked person i've ever met. Excited for you to see his work soon!

Shortcut can now spin up 1000's of agents to parallel search, but we built the feature entirely around the filesystem - enabling some pretty cool new things
Here I fill out a huge table of VCs we tracked for a fundraise and another table that has subtables, merged cells, etc.

/Autonomous is now default on in Shortcut.
@BrainsAndTennis built it before Codex released /goal and has gotten pretty awesome reviews.
You need runtime observability and verifiable goals for long term autonomy, and our solution to compacting is to never ever do it at all
I think it's safe to say Excel is solved.
The sign of an Excel rookie used to be manually using your mouse... now it's doing ANYTHING at all without AI.
If you use Excel do yourself a favor and watch all 3 mins.
It's a new world. Solving tasks in 20 mins that take teams days.

Fable 5 is the best model today, but for everyday spreadsheet task, you won't see a huge difference
You'll get much more gain with the right harness & environment
Codex + Mog is dramatically better than Codex's default spreadsheet skill, and almost as good as the best agents
Mog v0.9 is published!
Mog is the best spreadsheet for agents, and available wherever your agents are
Use it in Codex, Claude Code, etc. Just tell them to use npm mog-sdk/sdk, that's all
Use it with Shortcut agents, Cloudfare workers, etc
Edit xlsx in VSCode, Cursor, etc

I'm rebuilding Excel
Excel was designed for floppy disks and fax machines, we deserve something better now
Run xlsx headless, API for agents + UX for humans, colab, embeddable
Mog is the new way to Excel

For the second time now, @tryshortcutai was independently ranked as the top Excel AI agent in the world.
We specifically build for the top analysts, and this matches what we see on the ground.
It's firmly us, then Claude, or your firm forces Copilot upon you.
