Sarvam Unveils New Generation of Indian Large Language Models

India-based AI lab Sarvam has introduced a new lineup of large language models (LLMs) designed to deliver multilingual, low-cost, real-time capabilities for local and enterprise applications. The release marks a strategic shift toward smaller, compute-efficient open-source systems that can compete on practical features and regional language support rather than sheer parameter count alone.

Why this matters: efficiency, language coverage, and local use

The global LLM market remains dominated by massive systems developed by large U.S. and Chinese labs. Sarvam’s approach focuses on maximizing utility while minimizing operating cost — a trade-off that matters for startups, enterprises, and developers building for Indian languages and real-world conversational use. By optimizing architecture, context windows, and training data for multilingual Indian environments, Sarvam aims to make advanced AI more accessible across the region.

Key elements of Sarvam’s new lineup

• Two new sizes: a 30-billion-parameter model and a 105-billion-parameter model.
• Mixture-of-experts (MoE) architecture to activate only a subset of parameters during inference, reducing compute and cost.
• Large context windows: 32,000 tokens on the 30B model for fast conversational tasks and 128,000 tokens on the 105B model for complex, multi-step reasoning.
• Multimodal support with a text-to-speech model, a speech-to-text model, and a document-parsing vision model.
• Training-from-scratch methodology with multilingual corpora focused on Indian languages and domains.

These design choices reflect pragmatic trade-offs: targeted scale for latency-sensitive voice assistants and extended context for enterprise workflows that require long document understanding or multi-turn planning.

What makes Sarvam’s new LLMs different?

Sarvam emphasizes a few distinguishing priorities:

• Cost-effective inference: The MoE design reduces compute during inference by activating a fraction of experts, lowering cloud costs and enabling near real-time response in production settings.
• Large context flexibility: Support for 32K–128K token windows allows the models to handle long conversations, multi-document reasoning, and large code contexts.
• Multilingual focus: Training on trillions of tokens that include multiple Indian languages aims to improve comprehension, generation quality, and speech integration for regional markets.
• Real-world posture: Sarvam signals a measured scaling philosophy — prioritizing features and applications over raw parameter race.

How were the models trained and deployed?

Sarvam reported that both new models were trained from scratch, not produced by fine-tuning externally released weights. The 30B model was pre-trained on roughly 16 trillion tokens, while the 105B model drew on a diverse corpus spanning many Indian languages. Infrastructure and compute partnerships supported the effort, and the company has indicated plans to open source the 30B and 105B models — a move that could expand developer access and accelerate local innovation.

Training strategy highlights

Key training choices that shape performance and cost:

1. Mixture-of-experts architecture for efficiency.
2. Large-token pretraining to support extended context reasoning.
3. Speech and vision components trained to integrate with text models for multimodal scenarios.
4. Focus on end-to-end real-time capabilities, not only batch benchmarks.

Which applications will benefit first?

Sarvam is positioning these models for practical, early-use applications where latency, language coverage, and cost matter most:

• Voice assistants and conversational agents in Indian languages, which require fast speech recognition and natural speech synthesis.
• Enterprise assistants and document understanding that use long context windows to digest contracts, legal files, financial models, and long-form customer interactions.
• Developer and coding tools — the company is planning coding-focused models and enterprise tooling under a branded product suite.

For enterprises building localized products, the combination of multilingual training and extended context is particularly valuable. These models can enable agents that follow complex, multi-step workflows and remember state across long interactions.

What about openness, safety, and governance?

Sarvam has signaled an intent to open source the primary model weights for the two new models, though details around dataset release, full training recipes, and governance policies were not fully specified. Open-sourcing models can accelerate research and deployment at the edge, but it also raises questions about responsible release practices, safety mitigations, and content filters. Industry best practices suggest pairing open releases with clear usage policies, safety toolkits, and guidance for enterprise adopters.

Featured snippet: What are the technical specs and use cases of Sarvam’s models?

Short answer: Sarvam released 30B and 105B parameter mixed-expert LLMs with 32K and 128K token windows respectively, plus TTS, STT, and vision models aimed at multilingual, real-time voice and enterprise document applications.

Quick specs:

• 30B parameters — MoE architecture, 32,000-token context, pre-trained on ~16T tokens.
• 105B parameters — MoE architecture, 128,000-token context, trained on multilingual corpora spanning Indian languages.
• Additional models: text-to-speech, speech-to-text, and document-vision parser for multimodal pipelines.

How this fits into the broader Indian AI ecosystem

Sarvam’s announcement comes amid a wider push to build AI infrastructure, talent, and products in India. Locally optimized LLMs can unlock new consumer and enterprise services in regional languages, reduce dependency on foreign cloud costs, and create products that respect regional context and compliance needs. This launch also complements trends in on-device and sovereign AI, where compact, efficient models are preferred for latency, privacy, and cost reasons. For more on on-device processors aimed at sovereignty and efficiency, see our coverage of On-Device AI Processors: Quadric’s Push for Sovereign AI.

Multilingual models aimed at offline and low-bandwidth environments are a growing priority — for background on similar efforts, see our analysis of Tiny Aya Multilingual Models, which focuses on compact models for many languages.

Developer and enterprise considerations

Adopting these models will involve practical trade-offs for teams:

• Infrastructure: MoE models reduce inference cost per request but can introduce complexity in routing and serving. Evaluate latency budgets and serving topology carefully.
• Data and fine-tuning: While pretrained from scratch, many deployments will require domain fine-tuning or alignment layers for safety, brand voice, and regulatory compliance.
• Integration: Multimodal stacks (ASR, TTS, vision, text) benefit from tight integration and orchestration to meet real-time SLAs.
• Cost control: Efficient inference and selective expert routing can lower costs, but teams should benchmark token pricing, memory usage, and peak concurrency.

Teams building productized AI should also consider orchestration and memory layers that reduce redundant context processing. For enterprise memory strategies that trim costs, see our piece on AI Memory Orchestration.

Checklist for evaluating Sarvam models

1. Benchmark generation quality across target Indian languages.
2. Measure latency under expected concurrency and routing conditions.
3. Test multimodal workflow latency (ASR → NLU → TTS).
4. Assess fine-tuning and safety toolchain compatibility.
5. Plan deployment architecture: cloud, hybrid, or on-device proxies.

Limitations and open questions

Despite strong capabilities, there are areas where more transparency and evaluation would help adoption:

• Dataset composition and filtering practices for safety and bias mitigation.
• Availability of full training recipes and reproducibility details.
• Robustness benchmarks across dialects, low-resource languages, and noisy speech conditions.
• Operational playbooks for MoE deployment at scale.

Addressing these will be important if the open-source release is to gain trust among developers, enterprises, and civil society stakeholders.

Takeaways: measured scaling for real-world impact

Sarvam’s new 30B and 105B models reflect a practical strategy: scale where it helps product experiences, optimize for cost, and prioritize multilingual and multimodal features that serve a large domestic market. By focusing on real-time voice, extended-context reasoning, and enterprise workflows, the company targets applications where current mega-models are often expensive or ill-suited.

For Indian developers and companies, these models could lower the barrier to building localized AI agents, conversational apps, and document automation tools that work across regional languages and complex business workflows.

Next steps for adopters
