NPCI/nemo-gym-indian-banking

This is NPCI/nemo-gym-indian-banking — the dataset for the indian_banking resources server in NVIDIA NeMo Gym: 300 synthetic multi-turn Indian retail-banking customer-support tasks (250 train / 50 validation), the 197-customer synthetic bank database and the 59-article knowledge base the environment loads at startup.

NeMo Gym Indian Banking Agent Tasks

Tool-calling customer-service tasks for an Indian retail-banking assistant, in the NVIDIA NeMo Gym agent-input JSONL format. Each row is one task: a system prompt (agent instructions + bank policy), the 34 banking tool schemas, a simulated-customer scenario, and the evaluation criteria the indian_banking resources server uses to compute the reward after a rollout.

The dataset is consumed by the resources_servers/indian_banking server in NeMo Gym. The db.json customer database and kb.json knowledge base the server loads at startup ship in this repository alongside the splits (agent_instruction.txt and policy.md ship inside the Gym repository). gym dataset collate --download fetches the splits; download db.json and kb.json into resources_servers/indian_banking/data/ before serving.

Everything here is synthetic

No real customer, account, card, loan, or personal data is present. Every customer profile, account number, card number, transaction, name, address, phone number, e-mail and identifier in the customer database and in these tasks is synthetic. Any resemblance to real persons or accounts is coincidental.

Every bank, insurer, merchant, employer, telecom, card network and brand name is fictional (for example Streamvora, Vaylo Postpaid, Harvexa, Kalvira Life, Jeevanika Bima, Zyphrax / Orvelix / Swarnix card networks). Public institutions and government schemes are referred to by their real names (RBI, DICGC, NPCI, PPF, SSY, SCSS, APY, PMJJBY/PMSBY, PMJDY, Income Tax Act, state electricity boards) because the banking rules the agent must follow are defined by them. E-mail addresses use example.com / example.in; phone numbers use an obviously synthetic placeholder range. The knowledge-base articles describe generic Indian banking products and processes for a fictional bank; every article ends with the note "Figures are illustrative for a synthetic environment; verify current regulations."

Splits

split	rows	notes
train	250	43 task families; 155 rl_* core tool-use tasks (all 50 rl scenario templates covered) + 95 behavioural tasks
validation	50	disjoint from train; 19 task families, all 6 reward bases represented; the 5 committed example.jsonl rows are a subset of this split

There is no separate test split. train and validation are disjoint by task_id and were drawn from a larger pool with a seeded, stratified selection that covers every task family / reward-basis combination present in the pool, spreads customer ages (senior citizens are capped at about 19% of tasks), professions, regions and name communities, and excludes scenarios with stereotyped framing.

Reward-basis distribution (which signals the reward is computed from):

reward_basis	train	validation
ACTION+DB	155	31
ACTION+DB+NL_ASSERTION	49	11
ACTION+COMMUNICATE+DB+NL_ASSERTION	22	4
DB+NL_ASSERTION	11	1
ACTION+NL_ASSERTION	7	2
ACTION+COMMUNICATE+NL_ASSERTION	6	1

Row schema

One JSON object per line. Top-level keys:

field	type	description
responses_create_params	object	OpenAI Responses-API style create params consumed by the policy.
responses_create_params.input	list	Exactly one message: {"role": "system", "content": "<instructions>...</instructions>\n<policy>...</policy>"}. The first user turn is injected at runtime from opening_message.
responses_create_params.tools	list[34]	Function-tool schemas (type: "function", name, description, parameters). Identical across all rows.
responses_create_params.parallel_tool_calls	bool	Always false.
task_id	string	Unique task id. Prefix before the first _ is the task family (e.g. rl, kb, refuse, trap, mt2).
customer	string	Active, already-authenticated customer id (CUST_########) in db.json.
user_scenario	object	Simulated-customer specification.
user_scenario.persona	string	Short behavioural persona for the user simulator (not part of the reward).
user_scenario.instructions	object	domain ("banking"), reason_for_call, known_info, unknown_info, task_instructions (the simulator ends the call with ###STOP###).
evaluation_criteria	object	Reward specification.
evaluation_criteria.actions	list	Expected tool calls: {action_id, name, arguments, compare_args}; compare_args names which argument keys are compared, and a gold call that is expected to error carries expect_error: true.
evaluation_criteria.communicate_info	list[string]	Strings the agent must convey to the user (e.g. a policy number).
evaluation_criteria.nl_assertions	list[string]	Natural-language assertions checked by an LLM judge.
evaluation_criteria.reward_basis	list[string]	Subset of ACTION, DB, COMMUNICATE, NL_ASSERTION; the reward is the conjunction of the listed checks.
evaluation_criteria.max_tool_calls / .require_transfer	int / bool	Optional deterministic criteria: a cap on tool calls, and a requirement that the episode ends in transfer_to_human_agents.
initial_state	object	initialization_data.agent_data.active_customer selects the episode customer; initialization_data.user_data, initialization_actions and message_history are null on most rows — 114 tasks pre-shape the episode DB with initialization actions and carry a seed message history.
opening_message	string	The customer's first utterance; non-empty for every row.

The 34 tools: search_knowledge_base, get_account_balance, get_account_details, get_transaction_history, get_fd_details, get_rd_details, get_deposit_loan_rates, calculate_fd_maturity, calculate_rd_maturity, create_fd, create_rd, get_deposit_closure_quote, close_deposit, update_deposit_renewal, get_loan_details, get_loan_foreclosure_quote, calculate_emi, get_gold_rate, calculate_gold_loan_ltv, get_card_details, toggle_card_freeze, block_card, set_card_controls, show_mandates, cancel_mandate, stop_cheque_payment, request_cheque_book, request_duplicate_statement, update_address, raise_request, get_request_status, get_insurance_details, get_products_and_offers, transfer_to_human_agents.

Provenance and validation

• Synthetic, validated programmatically; every row carries its opening message.
• Every task's gold actions were replayed through the resources server's deterministic engine against the shipped db.json / kb.json and score strict == 1.0 under the server's reward.
• Reward semantics follow the tau2-bench style ACTION / DB / COMMUNICATE / NL_ASSERTION checks (order-strict action matching is a server-side setting; see the server README).

Synthetic data notice

Every customer, account, card, deposit, loan, mandate, transaction, address, e-mail address, phone number, employer and scenario in this benchmark is synthetic, generated for evaluation purposes. The bank itself is fictional. Any resemblance to real persons, living or dead, or to actual accounts, products or events is coincidental. Where names of real companies, payees or institutions appear in the data, they are used only as generic references to make scenarios read naturally; nothing in this repository describes their actual products, customers, transactions or policies, and no affiliation or endorsement is implied. The knowledge-base articles paraphrase publicly available regulatory and product information for the sole purpose of grounding the simulated agent; they are not advice and should not be relied upon.
