Find failures. Diagnose root causes. Test targeted fixes.
Prove they generalize.
Vector stores retrieve stale documentation or superseded policies lacking temporal recency ranking.
Agents invoke wrong API functions or pass malformed arguments causing unhandled schema validation errors.
Token window sliding and aggressive compression silently truncate user constraints mid-conversation.
Urgent customer requests trick the agent into bypassing business logic and refund authorization gates.
Adversarial inputs break system prompt encapsulation to extract coupons or trigger admin overrides.
Embedding search retrieves semantically similar but legally obsolete clauses instead of current amendments.
Multi-step conditional logic breaks down during complex exchanges, resulting in unauthorized promises.
Unhandled exceptions and tool timeouts leave customer sessions stuck in inconsistent state machines.
Generate scenarios, split into optimization, validation and holdout.
Trace each failure to a likely cause with evidence.
Try prompt, tool, retrieval, memory, guardrail or workflow fixes.
Measure each candidate on cases it was not tuned on.
Check holdout and regressions, then verify or reject.
Nebius Token Factory serves the high-throughput inference layer. NVIDIA Nemotron (nvidia/nemotron-3-nano-30b-a3b) handles test generation, causal failure reasoning and holdout judging. Tavily supplies external grounding evidence when a failure diagnosis requires current policy lookup.
