How to Train Your Advisor: Steering Black-Box LLMs with Advisor Models (2510.02453v1)
Abstract: Foundation models are increasingly deployed as black-box services, where model weights cannot be modified and customization is limited to prompting. While static prompt optimization has shown promise, it produces a single fixed prompt that fails to adapt to different inputs, users, or environments. We introduce Advisor Models, lightweight parametric policies trained with reinforcement learning to reactively issue natural language steering instructions in-context to black-box models. The advisor is a second small model that sits between the input and the model, shaping behavior on a per-instance basis using reward signals from the environment. Across multiple domains involving reasoning and personalization, we show that Advisor Models outperform static prompt optimizers, discovering environment dynamics and improving downstream task performance. We also demonstrate the generalizability of advisors by transferring them across black-box models, as well as the framework's ability to achieve specialization while retaining robustness to out-of-distribution inputs. Viewed more broadly, Advisor Models provide a learnable interface to black-box systems where the advisor acts as a parametric, environment-specific memory. We argue that dynamic optimization of black-box models via Advisor Models is a promising direction for enabling personalization and environment-adaptable AI with frontier-level capabilities.

Advisor Models: Reinforcement Learning-Based Steering of Black-Box LLMs
Introduction and Motivation
The proliferation of high-performing foundation models, such as GPT-5 and Claude 4.1, has led to widespread deployment of LLMs as black-box services accessible only via APIs. This paradigm precludes direct parameter updates, restricting customization to prompt engineering or post-hoc filtering. However, static prompt optimization is fundamentally limited: it produces a single, fixed prompt that cannot adapt to user-specific, input-specific, or environment-specific requirements. The paper introduces Advisor Models, a framework in which a lightweight, trainable advisor model issues instance-specific natural language advice to steer a black-box LLM, with the advisor trained via reinforcement learning (RL) using only API access to the black-box model.
Figure 1: Example of the Advisor Models workflow, where the advisor generates user-specific advice that is injected in-context to a black-box LLM, with RL-based training using only API access.
This approach reframes prompt engineering as a policy learning problem, enabling dynamic, per-instance adaptation and personalization. The advisor model, typically much smaller than the black-box LLM, is trained to maximize task-specific rewards derived from the outputs of the black-box model, without requiring access to its weights or gradients.
Advisor Models Framework
The Advisor Models framework consists of three core components:
- Advisor Model: A small, open-source LLM trained to generate instance-specific advice in natural language.
- Black-Box Model (Student): A powerful, frozen LLM accessible only via API, which receives both the original input and the advisor's advice in-context.
- Reinforcement Learning Loop: The advisor is trained using RL (specifically, Group Relative Policy Optimization, GRPO) to maximize rewards computed from the black-box model's outputs.
Figure 2: Advisor Models combine open-source advisor models with black-box LLMs, using RL to reinforce effective, instance-specific advice.
The training process involves sampling advice from the advisor, injecting it into the black-box model's context, generating the final output, and computing a reward based on task performance. The advisor is updated to maximize expected reward, with no modification to the black-box model. This modularity enables robust adaptation and avoids catastrophic forgetting.
Empirical Evaluation
Learning Hidden Latents and Personalization
The paper evaluates Advisor Models on tasks requiring the discovery of latent user preferences, such as review writing (with hidden preferences for review length or reading level) and math solution generation (with latent preferences for pedagogical style). In all cases, Advisor Models are compared to state-of-the-art static prompt optimizers (e.g., GEPA).
Figure 3: Advisor Models outperform static prompt optimization baselines in tasks with hidden latents, achieving near-perfect reward where baselines fail to improve over unoptimized models.
Key results:
- In review length and math solution tasks, Advisor Models achieve 94–100% of the possible reward, while static prompt optimizers remain at 40–60%.
- The advisor learns to generate advice that converges to the true latent preference, as evidenced by qualitative analysis of advice before and after training.
Effect of Advisor Initialization
The impact of advisor prompt initialization is analyzed. Strong initialization (with explicit hints about relevant axes) accelerates learning and leads to higher final performance, but even weak initialization (with minimal guidance) eventually achieves comparable results given sufficient training epochs.
Figure 4: Strong advisor prompt initialization leads to faster and better learning, but weak initialization can eventually reach similar performance with extended training.
Complex Reasoning and Over-Advising
Advisor Models are also evaluated on complex reasoning tasks, including mathematical problem solving (Omni-Math/MATH-500), low-resource translation (MTOB), and rule-based tax calculation (RuleArena). In these domains, Advisor Models provide significant improvements in out-of-distribution tasks requiring specialized knowledge, but only marginal gains in pure reasoning tasks where the black-box model is already strong.
A notable phenomenon, "over-advising," is observed: in complex tasks, the advisor sometimes solves the problem in its advice, with the black-box model simply copying or lightly modifying the solution. This shifts the advisor's role from steering to acting as a domain specialist, which can be mitigated by prompt engineering or post-processing.
Transferability and Robustness
The modular architecture of Advisor Models enables transfer of trained advisors across different black-box models. Advisors trained with one student (e.g., GPT-4o mini) can effectively advise others (e.g., GPT-5, Claude 4 Sonnet) with no loss in performance, enabling cost-effective training and deployment.
Figure 5: Advisor Models transfer across different black-box models, maintaining high performance and demonstrating generality of the learned policy.
Crucially, the system is robust to out-of-distribution inputs and does not degrade the black-box model's core capabilities, even when the advisor is heavily specialized or optimized for unrelated tasks.
Figure 6: Specializing the advisor does not degrade the student's core capabilities; performance on unrelated tasks remains statistically indistinguishable from the baseline.
Theoretical and Practical Implications
Advisor Models establish a new paradigm for controlling black-box LLMs via a learnable, interpretable, and environment-adaptive interface. The approach is strictly more expressive than static prompt optimization, as it enables per-instance adaptation and can capture user- or environment-specific latents. The modularity ensures that the powerful reasoning capabilities of the black-box model are preserved, while the advisor can be specialized, transferred, or replaced as needed.
From a theoretical perspective, Advisor Models can be viewed as a form of parametric, environment-specific memory, emitting control signals at inference time without storing histories or updating the black-box model's weights. This connects to broader discussions on memory and modularity in AI systems.
Practically, Advisor Models enable:
- Personalization and domain adaptation for black-box LLMs without access to weights or gradients.
- Cost-effective training via advisor transfer.
- Robustness to catastrophic forgetting and preservation of general capabilities.
- Potential for structured, multi-step guidance and more sophisticated forms of control.
Future Directions
Several avenues for future research are suggested:
- Designing advisor architectures capable of providing structured, multi-step, or hierarchical guidance.
- Exploring the use of advisor models as parametric memory modules for capturing long-term user or environment latents.
- Investigating the dynamics of hybrid advisor-student systems, including credit assignment, reward shaping, and mitigation of over-advising.
- Scaling Advisor Models to more complex, real-world personalization and adaptation scenarios.
Conclusion
Advisor Models provide a principled, RL-based framework for steering black-box LLMs via instance-specific, trainable advice. The approach achieves strong empirical results in personalization and out-of-distribution adaptation, outperforming static prompt optimization and demonstrating robustness and transferability. The modular design preserves the general capabilities of the black-box model while enabling dynamic, environment-adaptive control. This work lays the foundation for future research on learnable interfaces to black-box AI systems, with significant implications for personalization, robustness, and the development of modular, memory-augmented AI architectures.

Overview
This paper introduces a simple idea with a big impact: use a small “advisor” AI to guide a larger, more powerful AI that you can’t change on the inside (a “black box”). The advisor writes short, tailored tips in plain language for each input, helping the big AI give better, more personalized answers. Think of it like a coach passing notes to a star player during a game.
Objectives (What the researchers wanted to know)
The paper asks three main questions in easy terms:
- Can a small advisor learn hidden preferences (like a user’s favorite writing style) that aren’t written in the prompt?
- Can an advisor help a big AI do better on hard reasoning tasks (like math, taxes, or translation)?
- Will this approach stay reliable—working across different big AIs and not breaking the big AI’s general skills?
Methods (How it works, explained simply)
Here’s the setup:
- The big AI (the “student”) is a black box. You can only send it messages and read its replies. You can’t change its inner code or weights.
- A smaller AI (the “advisor”) sits in front of it. For every input (like “Write a review for Alex” or “Translate this sentence”), the advisor writes short advice in natural language (for example, “Keep it under 200 words” or “Use simpler words”).
- Both the original input and the advisor’s advice are then sent to the big AI. The big AI produces the final answer.
How the advisor learns:
- The advisor is trained with reinforcement learning (RL), which is like trial and error with a score:
- Try advice → big AI answers → compute a “reward” (a score) based on how good the final answer is.
- If the score is good, the advisor learns to give similar advice next time; if it’s bad, it tries different advice.
- They use a specific RL method called GRPO (you can think of it as a smart way of comparing several attempts to figure out what kinds of advice work best).
- For very hard problems, they use a 3-step version: the big AI first makes a draft, the advisor critiques/guides it, then the big AI revises its answer. This reduces the risk of bad advice.
Key terms made simple:
- Black box model: like a locked machine you can talk to but can’t open or change inside.
- Reward: a score based on how good the final output is (for example, correct/incorrect, or how well it matches a user’s preference).
- Static prompt vs. dynamic advice: a static prompt is one fixed instruction used every time (like a single sticky note). Dynamic advice is customized per input (like a coach whispering tips tailored to each play).
Findings (What they discovered and why it matters)
The researchers tested three kinds of tasks:
- Personalization and hidden preferences
- Review length and reading level: The advisor learned each user’s unstated preferences (like how long the review should be or what reading level to write at). It reached near-perfect scores (for example, ~96% match on length and 100% match on reading level), while the best “static prompt” method barely improved over the baseline.
- Math tutoring style: The advisor learned stylistic preferences (like “include questions for the student” or “show multiple methods”) without hurting the correctness of the math.
Why this matters: It shows the advisor can “discover” and adapt to hidden rules—something a single fixed prompt struggles to do.
- Complex reasoning and domain knowledge
- Math reasoning (Olympiad-style problems): Only a small gain (about 62% to 65% accuracy). This suggests that giving general reasoning skills as advice is tough.
- Low-resource translation (Kalamang → English): Big improvement (metric increased from about 28.1 to 43.7), likely because the advisor can inject helpful, task-specific hints.
- Rule-based taxes problems: Clear improvement (about 56% to 64% accuracy), again where targeted guidance and rules matter a lot.
Why this matters: The advisor shines when it can add missing, specialized knowledge or rules. It helps less when the task needs deep, step-by-step reasoning that the big AI already mostly knows.
A surprising behavior: “Over-advising”
- In some hard tasks, the advisor started solving most of the problem itself in its advice, and the big AI mostly copied or lightly edited the advisor’s solution.
- This isn’t necessarily bad—it’s like training a smaller domain expert that boosts the big model’s performance—while still keeping the big model’s broad skills intact.
- Robustness and transfer
- Transfer across big AIs: An advisor trained with one big AI could guide other big AIs without losing performance. That means you can train cheaply with one model and use the advisor with a different, more expensive model later.
- Keep general skills: Because the big AI’s weights never change, its core abilities don’t get worse (no “catastrophic forgetting”). Even advisors trained for unrelated tasks didn’t hurt math correctness. The system stayed stable.
Extra note on starting hints:
- If you give the advisor a good starting hint (like “focus on review length”), learning is faster.
- Without hints, it can still learn, just more slowly.
Implications (Why this work is useful)
- Personalized AI without touching the black box: You can adapt powerful API-only models to different users, tasks, or environments by training a small helper model that speaks natural language.
- Works where fixed prompts fail: Instead of one generic instruction, the advisor writes helpful, input-specific tips that change with the situation.
- Keeps strengths, avoids forgetting: The big AI remains a general expert; the advisor adds flexible, specialized guidance on top.
- Cost-effective and portable: Train the advisor with cheaper models, then use it to steer stronger ones.
- A step toward “parametric memory”: The advisor acts like a compact memory of user preferences or environment rules, recalled as short advice at the right time.
In short, this research shows a practical way to make strong, locked-down AI systems feel smarter, more helpful, and more personal—by training a small coach that learns, adapts, and guides them in real time.

Notes on feasibility and system design across applications:
- Reward design is pivotal: use reliable, automatable signals (correctness, policy matchers, classifiers, rubrics) and validate with human evaluation.
- Latency and cost: a second “advice” call adds overhead; batch or cache advice for repeated users/tasks; consider the three-step variant selectively.
- Safety and compliance: prevent advisors from inadvertently enabling jailbreaking or leaking sensitive info; employ safety classifiers and human gating.
- Robustness and drift: monitor advisor effectiveness post-deployment; detect over-advising and content copying; use editor filters or prompt constraints where needed.
- Transfer and portability: advisors often transfer across black-box models, enabling cost-effective training; validate per task before widescale deployment.
