Bengali NLP API in India

Bengali is among India's most widely spoken languages, with a large base of readers, shoppers, and support customers across West Bengal and the eastern region. Teams building Bengali-language chatbots, review analysis, or document tools don't need a foreign card or a complicated multi-vendor bill to start — unoblox gives you one OpenAI-compatible endpoint, billed in rupees on a monthly GST invoice, to test how today's large multilingual models actually handle Bengali.

There's no dedicated Bengali model — and that's honest

No model in unoblox's catalog is trained specifically for Bengali. What you get instead are large general-purpose multilingual models — from DeepSeek, Qwen, Llama, and GPT families — trained on broad multilingual corpora that include Indian languages. Quality on Bengali varies by model and by task: a model that summarises Bengali news well may stumble on colloquial, code-switched chat. The only honest approach is to test two or three candidates against your own prompts before picking one.

Models worth testing for Bengali text

Model	₹ input / ₹ output (per 1M tokens)	Why test it
qwen/qwen3-235b-a22b-instruct-2507	₹9.07 / ₹55.44	Large mixture-of-experts model at a moderate rate; a strong first candidate.
deepseek-ai/deepseek-v3.2	₹26.21 / ₹38.30	Balanced input/output pricing; a useful second opinion on tone and fluency.
meta-llama/llama-4-maverick-17b-128e-instruct-fp8	₹20.16 / ₹80.64	Meta's newer multilingual line; worth a side-by-side comparison.
openai/gpt-5	₹126 / ₹1008	The highest general-quality option in the catalog; costlier, so reserve it for cases where accuracy matters most.
qwen/qwen3-1.7b	FREE (₹0)	A zero-cost sandbox for early prototyping before you commit spend to a paid model.

Where teams use Bengali NLP

• Customer support triage and auto-drafted replies for D2C and BFSI apps

A sample call

curl https://api.unoblox.ai/v1/chat/completions \
  -H "Authorization: Bearer ub-gw-xxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "qwen/qwen3-235b-a22b-instruct-2507",
    "messages": [{"role": "user", "content": "Summarise this Bengali customer review in two lines."}]
  }'

Point any existing OpenAI SDK at https://api.unoblox.ai/v1 with your ub-gw-... key — streaming, JSON mode, and tool calls work the same way.

What "India" means here

The rupee benefit is real: one endpoint, one key, one monthly GST invoice with input-tax-credit, and no international card. What it isn't is data residency for the large foreign-trained models above — GPT, Claude, DeepSeek, Qwen, and Llama models run on their providers' own infrastructure outside India. Only unoblox's small, unoblox-hosted models run on Indian infrastructure. See /models for what's currently hosted where.

Frequently asked questions

Is there a model built specifically for Bengali? No. unoblox doesn't offer a Bengali-only model; you choose from general multilingual models and test which fits your task.

Which model gives the best Bengali output? It depends on your task — summarisation, sentiment, and transliteration can rank models differently. Run your own prompts against two or three candidates before committing.

Can a model handle Bengali-English code-switching? Reasonably well in most large models, though quality still varies — treat it as something to test rather than assume.

Is pricing really quoted in rupees? Yes. Every model on unoblox is priced and billed in rupees per million tokens, with a monthly GST invoice.

Can I reuse my existing OpenAI SDK code? Yes — change the base URL to https://api.unoblox.ai/v1 and the key to your ub-gw-... key; the request and response shapes are unchanged.

Is there a free way to prototype? Yes — qwen/qwen3-1.7b is free (₹0), so you can build and test your prompt flow before spending on a larger model.
