Big customer for the EU tier of decisionmodels.io! Scaling up GPU capacity.
These are our own models, and we will of course serve them at decisionmodels.io.
We'll anounce more details soon.
Meet REAX 1, our open decision model built on Perplexity Decider v1.2.
Our own measurement: +2.4 points over its base, ahead in all 6 test draws and all 10 areas.
Open competition starts today 13:00 UTC:
=> Beat it, earn the rewards

Our decision models and the open-source Auto Router are now live on AntSeed, EU tier included 🇪🇺
Decision Models is now on @antseed 🎉
• Our decision models, including an EU tier
• Our Auto Router: it picks the best model for each request to give you excellent price/capability

Next router on Antseed: Decision Models 🐜
An auto router that picks the model and seller for every request, with an open-source implementation you can inspect and adapt to your own needs

Bittensorians, please take note.
I have informed him of @decisionmodels_ in answer to #2.
I’m the CEO of Product Hunt and see 100s of launches a week. My current thoughts on new infra begging for startups:
1) Voice AI - infra for voice agents is getting really good w @pipecat_ai @Vapi_AI @DeepgramAI @ElevenLabs et al. and yet I rarely see good voice tech in the real world.
2) Decision Models - Jev / @typesafeai leading the charge. It reminds me of the mech-building in Zelda TOTK - an explosion of possibilities!
3) Personal Agents - they work now. And they need tools, apps, MCPs.
4) Extensions (OpenAI). We all live in agentic interfaces now. It’s like a new platform. Someone needs to build a Slack replacement that lives in Codex, for example.
The engine inside of decisionmodels.io, and the reason why we most likely can serve these models faster than you may have seen them anywhere else.
Use leading Jev class models
- blazing fast and
- for crazy low prices

Introducing REAX, Bittensor subnet 92!
An open network about AI decision models:
- miners host, train and spped-up models
- validators test correctness
- and customers use them through decisionmodels.io
A gaming GPU is enough to join. reax.co

Introducing DecisionModels @decisionmodels_
I've spent the last four weeks benchmarking decision models (I run JevBench).
Today I'm launching the place to actually use the best ones:
decisionmodels.io
➡️Top open models
➡️Up to 4x faster on our own REAX engine
➡️From $0.019 per 1M input tokens.
Expect more reveals soon, and read 👇
We're releasing s1-llm-auto-router as open weights:
A small decision model that reads a request and picks the right LLM for it.
▸ 26 ms on a CPU, 22 languages, MIT license
▸ Our first use-case-specific decision model, from decisionmodels.io and Bittensor Subnet 92 (REAX)
▸ The best of the decision models we tested for this use case.
▸Now live on decisionmodels.io.
We're also announcing a joint project with msg group:
msg will evaluate the model in an internal project to make its use of LLMs more efficient. msg is one of Germany's top 5 IT consultancies (€1.5B revenue, 10,000+ employees).
Thank you, Dr. Ralf S. Engelschall (@engelschall), CTO of msg and one of the founding members of the Apache Software Foundation.
We believe use-case-specific decision models will become a huge market. More from us soon.

How it compares on our own held-out routing test (2,175 synthetic requests in 22 languages, labels from a 5-LLM consensus, method in the model card):
It picks the same model as the gold label 74% of the time, the best of the decision models we tested, at 26 ms on a CPU.
On JevBench:
As its operator, we never rank our own models there. And a specialist like this isn't a fit for general decision-model benchmarks anyway, so we measured it on the task it was built for.
Hi, we're DecisionModels.
The best open decision models, served fast through one API:
→ s1-pro runs vLLM-SR d3, the most capable decision model in the world *
→ up to 4x faster on our own REAX engine
→ s1-fast from $0.019 per 1M input tokens (about 1.6x cheaper than Jev), output free
→ EU-hosted option with a DPA, built for GDPR and the EU AI Act
decisionmodels.io
* according to both the Decision Index on Hugging Face and the Capability Score on JevBench (our founder's own project)
Served by REAX, an open inference network on Bittensor subnet 92.
A gaming GPU is enough to participate.
