What do these tasks have in common?

- Fixing security vulnerabilities
- Data entry from messy unstructured forms
- Version upgrades

They're repetitive but important tasks that can be solved in a few lines of code by our new OpenHands Software Agent SDK.

3/ This week we are proud to announce our latest eval with the latest version of @allhands_ai's OpenHands and GPT-5.

Remarkably, GPT-5 increased the SOTA on SWT-Verified by 15%, taking 1st, and GPT-5-mini took a well deserved 3rd spot. 🏅

[Robert Brennan @rbren_dev]

A lot of agents out there are over-optimizing for SWE-bench. We've been very careful to ensure OpenHands generalizes to a wide variety of eng-related tasks

Great to see that work pay off as we hit #1 on SWT-Bench!🏆

[Juan Michelini @juanontech]

OpenHands is 🥇 place on the SWTBench the unit test benchmark. Great team, great product, and the benchmarks prove it!

[OpenHands @OpenHandsDev]

Having appropriate tests makes a world of difference for agent-driven development.

If your agent can write a test to localize a bug or exercise a new feature, the following implementation is much more solid.

OpenHands+GPT-5 is now 🥇 on the SWT-Bench testing leaderboard!

[OpenHands @OpenHandsDev]

We evaluated GPT-5 in OpenHands and it's the new number one coding agent model for us!

Using exactly the same tools and harness it's 1.4 points better than Claude Sonnet 4 at 60% of the price.

@MistralAI Try it out in OpenHands following the directions here! https://t.co/1KvC6IJfGP

Introducing the OpenHands CLI, a new coding CLI that:

- Has top accuracy (similar to Claude Code)
- Is completely open source, MIT licensed
- Is model agnostic, use an API or bring your own
- Is simple to install and run `pip install openhands-ai` and `openhands` (no Docker!)

[Juan Michelini @juanontech]

@engelnyst Yes! Software Engineering is the first thing we automate because it's the one we know the best. Also, that's where all the exponential growth comes from.

[Juan Michelini @juanontech]

@gneubig @Aditya_Soni_8 @allhands_ai @gneubig @Aditya_Soni_8 Excited about the results! 🚀

[Graham Neubig @gneubig]

I am very excited about both the accuracy results and just my feeling playing around with this new agent.

The ability to research things online and comprehend a wide variety of multimodal content has removed many of my blockers in using agents in my everyday work.
