Custom models
trained on your data

Sarvam manages fine-tuning, reinforcement learning, and evaluation on infrastructure in India. You receive the trained weights.

When custom training is useful

Custom training adapts model behaviour to proprietary data, institutional policies, and task-specific evaluation criteria.

Institutional data

Internal documentation, historical decisions, and domain terminology become training inputs.

Controlled behaviour

Define tone, refusal policies, and output formats. We evaluate the trained model against each requirement.

Smaller models for specific tasks

A smaller specialised model can reduce latency and inference cost for a defined task.

Managed model training

Training data

  • STRUCTURED
  • UNSTRUCTURED

Customer-managed training

Your team manages capacity, training runs, recovery, alignment, and evaluation.

Training methods

We select the training method during scoping based on the task, the dataset, and the evaluation criteria.

01

Adaptation

What it is

Parameter-efficient fine-tuning with LoRA on an existing model. It updates a subset of parameters and supports shorter iteration cycles.


Best for

Defined tasks with a few thousand high-quality training examples.

02

Specialisation

What it is

Full-weight fine-tuning with alignment against agreed policies and evaluation criteria.


Best for

Production workloads that need a smaller model for a specific domain or task.

Separate research engagement

Frontier model co-build

Sarvam’s research team works with your team to build a model from the ground up. Scope, data requirements, and evaluation are defined separately.

Where custom training is used

Each engagement starts with proprietary data, operating policies, and a defined task.

Underwriting models trained on lending data

Training inputs can include risk parameters, repayment histories, and past credit decisions. Evaluation measures how the model applies the institution’s underwriting policy.

Claims models trained on policy and case data

Policy wordings and historical claim files provide the training data. Evaluation covers the edge cases handled by senior assessors.

Citizen-service models trained on departmental content

Training uses departmental documents and service workflows. Evaluation measures answer quality across the languages covered by the service.

Clinical documentation models trained on care protocols

Formularies and care pathways provide the training data. Evaluation checks first-pass documentation against the institution’s protocols.

Contract review models trained on internal precedents

Contracts and internal guidance provide the training data. Evaluation checks first-pass review against the organisation’s positions.

How Sarvam runs the engagement

  • Sarvam model-training systems

    Customer engagements use the same research and infrastructure teams.

  • Managed training infrastructure

    Sarvam handles GPU capacity, cluster configuration, run orchestration, and recovery.

  • Evaluation defined before training

    We agree on evaluation sets and acceptance criteria during scoping, then measure the trained model against them.

  • Written engagement terms

    The engagement defines data access, retention, deletion, and weights delivery before training begins.

Engagement terms

Training location and model delivery

Sarvam trains the model on its infrastructure in India. After delivery, the weights can run in a compatible standard runtime or through Sarvam Inference.

Training
Training runs on Sarvam infrastructure in India. Training data is isolated to the engagement and used only for the contracted model.
The model
We deliver a standard weights checkpoint in a format supported by common model runtimes.
Running it
The weights can run in a compatible standard runtime. Sarvam Inference is available as a managed option.

Data transfer starts after scoping and contract approval.

Ownership and data commitments

These terms are agreed in the contract before data transfer begins.

Sarvam AI Platform

Ownership of trained weights

The contract assigns the trained weights to the customer. The customer can run, modify, or host them.

No reuse of training data

Training data is isolated to the engagement. It is not pooled with other customers or used to train Sarvam models.

Training data remains in India

Training runs on infrastructure in India. The customer chooses where to run the weights after delivery.
