Introduction

Sarvam-105B is an advanced Mixture-of-Experts (MoE) model with 10.3B active parameters, designed for superior performance across a wide range of complex tasks. It is highly optimized for complex reasoning, with particular strength in agentic tasks, mathematics, and coding.

Sarvam-105B is a top-tier performer, consistently matching or surpassing several major closed-source models and staying within a narrow margin of frontier models across diverse reasoning and agentic benchmarks. It demonstrates exceptional agentic and reasoning capabilities in real-world applications such as web search and technical troubleshooting.

A major focus during training was the Indian context and languages, resulting in state-of-the-art performance across 22 Indian languages for its model size.

Sarvam-105B is open-sourced under the Apache License. For more details, see our blog.

Architecture

The 105B model adopts an MLA-style attention stack with decoupled QK head dimensions (q_head_dim=192 split into RoPE and noPE components, v_head_dim=128) and a large head_dim of 576, enabling higher representational bandwidth per head while keeping the hidden size at 4096. This approach improves attention expressivity and long-context extrapolation (via YaRN scaling with a factor of 40 and 128K context). It has an intermediate_size (16384) and moe_intermediate_size (2048), combined with top-8 routing over 128 experts, which increases per-token active capacity while keeping activation cost manageable. The model has one shared expert, a routed scaling factor of 2.5, and auxiliary-loss-free router balancing.

SGLang

Install latest SGLang from source

bash

git clone https://github.com/sgl-project/sglang.git
cd sglang
pip install -e "python[all]"

Instantiate model and Run

python

import sglang as sgl
from transformers import AutoTokenizer

model_path = "sarvamai/sarvam-105b"
engine = sgl.Engine(
    model_path=model_path,
    tp_size=4,
    mem_fraction_static=0.70,
    trust_remote_code=True,

vLLM

Note: currently a PR is open for native support for the Sarvam models in vLLM (link). Therefore, we have 2 options here.

Option 1: install from source (hard)

Use the custom fork here: link
Follow the instructions here to install from source: link

Option 2: hot-patch (easy)

Run hotpatch_vllm.py
This will do the following:
- install vllm=0.15.0
- add 2 model entries to registry.py
- download the model executors for sarvam-105b and sarvam-30b

Once this is done, you can run vLLM as usual

python

from vllm import LLM, SamplingParams
from transformers import AutoTokenizer

model_path = "sarvamai/sarvam-105b"
tokenizer = AutoTokenizer.from_pretrained(model_path)
llm = LLM(model=model_path, 
            trust_remote_code=True, 
            max_model_len=2048, 
            tensor_parallel_size=8, 
            max_num_seqs=16,
        )
sampling_params = SamplingParams(
                    temperature=0.8, 
                    max_tokens=2048, 
                    repetition_penalty=1.0,
                    spaces_between_special_tokens=True
                )

prompts = [
    "Which artist painted The Persistence of Memory (the melting clocks)?",
]

outputs = llm.generate([
    tokenizer.apply_chat_template([
        {"role": "user", "content": prompt}],
        tokenize=False,
        add_generation_prompt=True,
        enable_thinking=True)
        for prompt in prompts], 
    sampling_params)
for p, o in zip(prompts, outputs):
    print("Prompt: ", p)
    print("Generated text: ", o.outputs[0].text)
    print("=" * 100)
