Move with Humility, Go Deep with Purpose

We don't build all-purpose general intelligence — we build vertical AI that truly knows your domain. In your industry, we make the technology deep, solid, and genuinely usable.

Model Fine-tuning

Turning industry know-how into models of your own

Not generic — truly versed in your domain.

We turn the business data your enterprise has accumulated in its vertical into industry models that can be deployed on-premise. Data never leaves your company, capabilities keep compounding, and every investment becomes a reusable asset that powers your business flywheel.

Delivery & Pricing

The model is the deliverable — You receive the model itself, ready to plug into your business systems.
Priced by task difficulty — One-time quotes based on task difficulty — costs are transparent and predictable.
Ongoing iteration — Continuous optimization after launch, growing with your business (performance tuning and maintenance billed separately).

Technical Consulting

Do the right things, in the right direction

For AI adoption in verticals, the hardest part isn't the technology — it's the judgment.

With a deep understanding of industry scenarios, we provide expert advice at key decision points, helping enterprises avoid technologies that look great on paper and invest resources where they truly create value.

Scope of Consulting

Feasibility assessment — Technical feasibility evaluation — should it be done, and is it worth it?
Technology selection — Choosing the right technical route, with implementation advice.
Performance iteration — Planning the path to better results, so your investment keeps paying off.

Billing: pay by consulting hours — lightweight and flexible.

Technical Services

On the ground, landing together with your business

Good solutions grow inside the business.

We don't deliver slide decks floating in the air. We embed deeply into your actual business and workflows, participating end-to-end from requirement understanding and solution design to development and delivery — producing technical results that stand up to real business scrutiny.

How We Work

Deep co-creation — More than a proposal — we dive into your business and workflows to get the solution up and running.
End-to-end ownership — Involved throughout, from requirements and solution design to development and delivery.
Tailored per project — Billing and deliverables are negotiated and customized per project.

Jul 28, 2026Accelerating GRPO with Down-SamplingPODS (Policy Optimization with Down-Sampling) keeps only an informative subset of rollouts for the policy update: max-variance down-sampling (keeping the subset with the largest reward variance) makes GRPO at least 1.7x faster with equal or better performance, with an efficient O(n log n) selection algorithm.2026-07-28Read more →

Jul 16, 2026When Updating Parameters, RL Takes the Path Not TakenRLVR updates only a small fraction of parameters, and the update regions overlap across different RL algorithms and datasets — the update trajectory is model-conditioned. The paper explains this with a Three-Gate Theory (KL leash, model geometry, bf16 precision): RL learns off the principal directions in weight space, while SFT targets principal weights. Implications: SFT-era PEFT techniques may not suit RL.2026-07-16Read more →
