Quickstart

The following code snippet demonstrates how to use sarvam-m using Transformers.

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "sarvamai/sarvam-m"

# load the tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name, torch_dtype="auto", device_map="auto"
)
# prepare the model input
prompt = "Who are you and what is your purpose on this planet?"

messages = [{"role": "user", "content": prompt}]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    enable_thinking=True,  # Switches between thinking and non-thinking modes. Default is True.
)

model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

# conduct text completion
generated_ids = model.generate(**model_inputs, max_new_tokens=8192)
output_ids = generated_ids[0][len(model_inputs.input_ids[0]) :].tolist()
output_text = tokenizer.decode(output_ids)

if "" in output_text:
    reasoning_content = output_text.split("")[0].rstrip("\n")
    content = output_text.split("")[-1].lstrip("\n").rstrip("")
else:
    reasoning_content = ""
    content = output_text.rstrip("")

print("reasoning content:", reasoning_content)
print("content:", content)

For thinking mode, we recommend temperature=0.5; for no-think mode, temperature=0.2.

With Sarvam APIs

from openai import OpenAI

base_url = "https://api.sarvam.ai/v1"
model_name = "sarvam-m"
api_key = "Your-API-Key"  # get it from https://dashboard.sarvam.ai/

client = OpenAI(
    base_url=base_url,
    api_key=api_key,
).with_options(max_retries=1)

messages = [
    {"role": "system", "content": "You're a helpful AI assistant"},
    {"role": "user", "content": "Explain quantum computing in simple terms"},
]

response1 = client.chat.completions.create(
    model=model_name,
    messages=messages,
    reasoning_effort="medium",  # Enable thinking mode. `None` for disable.
    max_completion_tokens=4096,
)
print("First response:", response1.choices[0].message.content)

# Building messages for the second turn (using previous response as context)
messages.extend(
    [
        {
            "role": "assistant",
            "content": response1.choices[0].message.content,
        },
        {"role": "user", "content": "Can you give an analogy for superposition?"},
    ]
)

response2 = client.chat.completions.create(
    model=model_name,
    messages=messages,
    reasoning_effort="medium",
    max_completion_tokens=8192,
)
print("Follow-up response:", response2.choices[0].message.content)

Refer to API docs here: sarvam Chat Completions API docs

reasoning_effort can take three possible values: low, medium, and high to be consistent with the OpenAI API spec. Setting any of the three values just enables the thinking mode of sarvam-m.

vLLM Deployment

For easy deployment, we can use vllm>=0.8.5 and create an OpenAI-compatible API endpoint with vllm serve sarvamai/sarvam-m.
If you want to use vLLM with python, you can do the following.

from openai import OpenAI

# Modify OpenAI's API key and API base to use vLLM's API server.
openai_api_key = "EMPTY"
openai_api_base = "http://localhost:8000/v1"

client = OpenAI(
    api_key=openai_api_key,
    base_url=openai_api_base,
)

models = client.models.list()
model = models.data[0].id

messages = [{"role": "user", "content": "Why is 42 the best number?"}]

# By default, thinking mode is enabled.
# If you want to disable thinking, add:
# extra_body={"chat_template_kwargs": {"enable_thinking": False}}
response = client.chat.completions.create(model=model, messages=messages)
output_text = response.choices[0].message.content

if "" in output_text:
    reasoning_content = output_text.split("")[0].rstrip("\n")
    content = output_text.split("")[-1].lstrip("\n")
else:
    reasoning_content = ""
    content = output_text

print("reasoning content:", reasoning_content)
print("content:", content)

# For the next round, add the model's response directly as assistant turn.
messages.append(
    {"role": "assistant", "content": output_text}
)
