Enterprise AI Agentic Reliability Report
How Do LLMs Fail In Agentic Scenarios?
This study investigates the failure modes of large language models (LLMs) when deployed as autonomous agents with tool-use capabilities. Analyzing 900 execution traces across diverse scenarios, we uncover crucial insights into agentic reliability beyond mere performance scores. Our findings highlight that recovery capability, rather than initial correctness or model scale, is the primary driver of success in complex, interactive tasks.
Executive Impact: Key Findings
Our comprehensive analysis reveals key performance metrics and behavioral patterns across leading LLM models in agentic simulations, identifying critical differentiators for enterprise deployment.

Recurring Failure Archetypes
DeepSeek V3.1's superior reliability stems from its consistent ability to interpret error messages, diagnose root causes, and iteratively refine its approach, rather than simply avoiding errors. This contrasts sharply with other models that struggle with sustained debugging.
| Capability | Granite | Maverick | DeepSeek |
|---|---|---|---|
| Detect malformed tool calls | Medium | High | Very High |
| Successful use of error feedback to self-correct | Low | High | Very High |
| Escape perseverative loops | Poor | Medium | High |
| Self-debug Python/SQL | Poor | Inconsistent | Frequent |
Eye-balling CSVs Instead of Python Tool (Q401)
Granite 4 Small consistently avoids the optimal Python-execution strategy in CSV-analysis tasks (Q401–Q403), instead reading the CSV and attempting to 'eye-ball' large aggregated values. This strategy always fails due to miscounting rows or producing approximate float averages, highlighting a fundamental gap in tool-use strategy for complex computation. It shows an over-reliance on normal inference when structured tools are required.
In SQL-based tasks (Q501-Q503), Granite 4 Small repeatedly guesses table and column names instead of inspecting the schema, leading to avoidable errors, incorrect JOIN logic, and misinterpretations. While some recovery is observed, it’s a costly and inefficient strategy.
DeepSeek V3.1 succeeded in all trials of Q201-Q202, Q302, Q401, Q403 and Q501, consistently following optimal multi-step strategies with correct tool sequencing and no hesitation. This demonstrates its highly reliable execution in structured tasks.
Proactive Data Validation in SQL (Q501)
A defining characteristic of DeepSeek V3.1 is its tendency to proactively verify assumptions before proceeding, such as validating region codes (Q501) or re-checking schema when results seem implausible. This systematic verification and value checking prevents silent failures and highlights its robust agentic reliability.
DeepSeek V3.1, despite its overall strength, is still vulnerable to semantic confusion from distractors, failing 10 out of 30 Q503 trials by fixating on irrelevant tables or incorrect aggregation logic. This demonstrates sensitivity to context pollution.
Context Fragility: Misinterpreting CWD (Q202)
In Q202, Llama 4 Maverick, after seeing the 'get_cwd' output, fixated on the current working directory as the target for file creation, forgetting the absolute path from initial instructions. This demonstrates a severe vulnerability to context pollution and distraction, leading to critical misinterpretations of the environment.
Llama 4 Maverick's performance is highly inconsistent; it often begins tasks with correct reasoning but frequently degrades mid-execution, leading to malformed tool calls, generation loops, and inconsistent recovery. This highlights its fragile execution under cognitive load.
Maverick regularly asserts incorrect assumptions with high confidence and often fills in missing entities implicitly rather than verifying them via schema inspection or tool usage. This over-helpfulness leads to autonomous substitution, violating task fidelity, likely due to alignment tuning.
1. Neither Size Nor General Capability Equal Agentic Reliability
Model scale alone does not predict agentic robustness. For instance, Llama 4 Maverick (400B) performs only marginally better than Granite 4 Small (32B) in some uncertainty-driven tasks, and DeepSeek V3.1's superior reliability derives from post-training reinforcement learning rather than raw scale.
2. Error Feedback Is The New Frontier For Autonomy
Agentic reliability is determined not by error absence, but by how effectively errors are converted into corrective action. Models must internalize tool semantics and system constraints, and error messages should suggest corrective paths.
3. Context Quality Matters More Than Context Quantity
The presence of distractor files or tables triggers semantic overreach, causing systemic failures even in the largest models. All provided context is treated as signal, not noise, highlighting the need for careful context engineering and avoidance of irrelevant or confusing data.
4. Literal, Source-of-Truth Alignment
Enterprise agents must prioritize actual data over their priors. Behaviors like guessing schemas or hypothesizing values must be inhibited. Grounded verification is essential for correctness under uncertainty, achievable through RL finetuning, system prompts, and tool message design.
