Unlike plain model routing, Fusion keeps frontier intelligence in charge.
We don’t rely on one initial routing decision. The lead reviews work, flags problems, and can take control back when the sidekick is out of its depth. https://t.co/4d9mRVkf2M

We partnered with @ArtificialAnlys and @ValsAI to evaluate Fusion across several coding agent benchmarks.
The cost savings hold across the board while maintaining frontier performance. https://t.co/CeffWEUwQ0

As a result, SWE-2 is our most capable model yet for software engineering tasks – while achieving market-leading price performance.
Our team at Cognition uses it for feature development, debugging, and even complex visualizations of novel math:

The result is a model that is way more efficient than SWE-1.7.
On FrontierCode 1.1 Main, SWE-2 medium scores higher than SWE-1.7 while taking 58% fewer turns and costing 81% less on average.
We observe that SWE-2 learns to explore in a more focused way before making changes. ht

SWE-2 is our first model to support effort levels. For that, we made significant improvements to our length penalty recipe - read more in our blog post!
In a single RL run, we are able to push the Pareto curve while preserving its shape: medium effort becomes both cheaper & htt

SWE-2 is post-trained on Kimi-K3 and proves that our RL recipe continues to scale on stronger base models.
On FrontierCode, SWE-2 achieves a score of 50.0%. It beats SWE-1.7, Grok 4.6, and GPT 5.6 Sol while matching Fable 5.1 at 64% lower cost. https://t.co/O8dARqVRhM

Introducing SWE-2, our closest model yet to the frontier.
On leading evals, it scores on par with recent frontier models – at up to 70% lower cost.
We scaled RL to multiple trillions of parameters, with a refined recipe that pushes the Pareto curve on both capabilities & cost.

In the next chapter of software engineering, agents will become proactive by default, software will improve itself, and compute will automatically get allocated toward the highest impact use cases.
We’re still at the dawn of the self-driving software era.
