Drex Max v1.1 Sets the Standard for Decision Model Performance
Artificial Analysis: multimodal decision model Drex Max ranks #1. Both achieving SOTA and Pareto frontier [N]

Nace's Drex Max v1.1 isn't just another model update, it's a deliberate signal that the decision-model category has finally matured. By achieving both state-of-the-art performance and a position on the Pareto frontier for efficiency, the team has done something more valuable than simply publishing a higher benchmark score: they've made the choice between capability and cost a false dichotomy. For anyone who has felt constrained by the trade-offs baked into traditional decision tools, this release offers a concrete path forward.

The numbers speak directly to the practical constraints that have held back adoption. Drex Max's 256k context window matches the largest competitor in the category while handling tasks that previously required models like Glide (64k) or Mammoth (16k). More striking is the cost advantage: Nace claims their model is eight times cheaper than the next best alternative in the AA index. That kind of efficiency shift changes the calculus for teams that have been rationing their use of decision models, treating them as a premium resource rather than a daily tool. As we discussed in Monitor Agent Behavior by Tracking Anomalies in Execution History, understanding how models behave over time is critical, and Drex Max's open weights and transparent training playbook make that kind of scrutiny possible. The team has also released a full paper, "Towards Foundation Decision Models: Drex," which lays out their iterative process step by step, including all previous model weights on Hugging Face. That openness is rare in a field where many vendors treat training methodology as proprietary black magic.

What makes this announcement feel different is the emphasis on local inference. The model can run on a Mac using Nace's Kapitsa engine, which points toward a future where powerful decision models aren't locked behind cloud APIs. For researchers and practitioners who value data sovereignty or need to operate in bandwidth-constrained environments, that matters. It echoes the sentiment we explored in Explore how a Mac Mini and iPad setup can complement your university AI access, where local hardware choices can unlock capabilities that cloud-only workflows restrict. The v1.1 weights are coming soon under an Open RAIL-M license, and the team is optimizing for local deployment, a practical commitment that aligns with the growing demand for models that users can actually own and inspect.

The open question is whether the decision-model category can sustain this trajectory. Drex Max sets a high bar, but the real test will come as more organizations try to integrate it into production pipelines. Nace's chief of AI has offered to answer technical questions directly, which suggests they understand that adoption depends on trust and transparency, not just benchmark bragging. The specific detail worth watching is how the local inference performance holds up at the full 256k context window on consumer hardware, if that works reliably, the category may finally have a model that doesn't require a data-center budget to use.

From Machine Learning

hey, its Alti from Nace. we released a small update with Drex Max v1.1, both achieving the SOTA and Pareto frontier for decision models. We did all that by iterating step by step and every previous version of Drex’s open weights are available on hf. We also released a full playbook on how we trained Drex Max in this paper: “ Towards Foundation Decision Models: Drex”
