Brio’s power lies in its ability to generate precise, context-aware, and human-sounding responses on LinkedIn. At the core of this capability is its flexible AI integration system. Brio supports multiple AI providers, giving users the freedom to choose the language model that best suits their workflow, tone, and goals.

This section will guide you through everything you need to know about configuring AI providers and selecting the most appropriate model for your needs. Whether you’re focused on persuasive outreach, multilingual communication, or highly structured B2B interactions, understanding Brio’s AI configuration settings will help you get the most out of your engagement profiles.

Supported Providers

Brio currently supports four major AI providers, each offering models with distinct strengths and capabilities:

1. OpenAI

Known for: Natural tone, coherent reasoning, and wide language support
Popular Models: GPT-4o, GPT-4o-mini, GPT-4.5

OpenAI is a widely trusted leader in natural language processing, and its GPT models are ideal for users looking for polished, professional responses. GPT-4, in particular, excels at maintaining conversational continuity, interpreting nuance, and mirroring subtle tone shifts—making it a solid choice for longer, deeper engagement threads.

Strengths:

• Smooth, fluid conversation flow
• Excellent at summarization and paraphrasing
• Broad knowledge across industries

Considerations:

• Slightly more verbose by default
• Often leans toward formal structure without fine-tuning

Best for: Recruiters working with international professionals, those seeking diplomatic and polished tone in outreach.

2. Google Gemini

Known for: Efficient response time and context adaptability
Popular Models: Gemini Pro

Gemini is designed for contextual awareness and fast processing. It generates compact, goal-oriented responses and handles multilingual inputs well. While it may not match GPT-4 in terms of narrative richness, Gemini tends to be faster and more direct—especially useful in high-volume outreach.

Strengths:

• Good at staying on topic
• Shorter, action-driven messaging
• Strong support for European languages

Considerations:

• Less conversational finesse than OpenAI in extended dialogues
• May occasionally under-express subtle emotional tone

Best for: Users running structured, transactional messaging with high throughput (e.g., follow-ups, initial outreach, confirmations).

3. DeepSeek

Known for: Research-grade analysis and technical writing style
Popular Models: DeepSeek Chat, DeepSeek Coder

DeepSeek is an emerging player that shines in analytical depth and structured content generation. It works well for highly specific prompts and excels in contexts where detail and process matter—such as explaining offers, handling objections, or breaking down complex proposals.

Strengths:

• Precision and step-by-step breakdowns
• Strong technical and instructional responses
• Analytical approach to objections and CTA alignment

Considerations:

• Tends to be dry or robotic without tuning
• May underperform in casual conversation tone

Best for: High-detail responses, technical explanation threads, and B2B contexts with clients who expect structure and clarity.

4. Grok

Known for: Real-time adaptability and persuasive messaging
Popular Models: Grok-1, Grok-2 1212 (stable)

Grok, developed with conversation in mind, brings a different flavor to Brio. Its standout model, Grok-2 1212, has proven itself remarkably reliable for LinkedIn recruiting conversations. It generates responses that are warm, persuasive, and cleanly tailored—ideal for situations requiring subtle influence without sounding generic.

Strengths:

• Sharp persuasive tone with minimal prompt tuning
• Balanced structure and brevity
• Excellent multilingual performance

Considerations:

• Less widely known than OpenAI or Gemini
• Limited fine-tuning options compared to OpenAI

Best for: Recruiters, founders, or sales professionals engaging in relationship-building and nuanced prospecting, especially when operating across multiple countries or languages.

Choosing the Right Model for Your Needs

With multiple models to choose from, it’s important to align your selection with your messaging goals. Below, we break down the key considerations based on real-world testing and documented results from Brio’s internal benchmarking.

1. Align with Your Outreach Objective

Each model brings a different communication style. Choosing one depends on whether your primary goal is conversion, relationship-building, technical clarity, or speed.

Objective	Recommended Model
Persuasion & Influencing	Grok-2 1212, GPT-4
Fast Follow-Up	Gemini
Deep Explanation or Objection Handling	DeepSeek
General-Purpose Professionalism	GPT-4, Grok-2

Example:
If you’re engaging passive candidates who need to be carefully nurtured toward the idea of switching jobs, Grok-2 1212 delivers natural, subtly persuasive responses without sounding salesy. In comparison, Gemini would be more suited to quickly summarizing an offer for someone who has already expressed interest.

2. Consider Language and Tone Requirements

Are you messaging people in multiple languages? Do you need the tone to be casual, friendly, or formal?

• Multilingual Outreach: Grok-2 and Gemini perform well in switching between languages while maintaining natural flow.
• Tone-sensitive Conversations: GPT-4 adapts well to different tones when finely prompted.
• High Formality and Structure: DeepSeek is ideal when precision outweighs emotional warmth.

Brio supports tone-matching through conversation analysis, but the base capability of the model matters. A persuasive tone in French will feel different than in Swedish or Polish—Grok and Gemini adjust well, while GPT sometimes overcorrects with unnecessary complexity in non-English languages.

3. Leverage Model Strengths by Scenario

Your daily workflow may involve several types of messaging. Here’s how you can strategically use different models for specific conversation types:

Scenario A: First outreach to passive candidate

• Model: Grok-2 1212
• Why: Best for introducing value subtly, asking thoughtful questions, and drawing recipients into the conversation.

Scenario B: Explaining recruiter earnings or terms

• Model: DeepSeek or GPT-4
• Why: These models provide more structured breakdowns of fee structures, milestones, and administrative details.

Scenario C: Quick follow-up after no reply

• Model: Gemini
• Why: It crafts direct, polite nudges that don’t overwhelm the recipient or repeat too much.

Scenario D: Handling skepticism or objections

• Model: GPT-4 or DeepSeek
• Why: They excel at parsing emotional signals and reframing objections without sounding defensive.

4. Backed by Testing: How Brio Benchmarks Responses

To validate model performance, Brio runs blind testing of multiple model responses on the same conversation threads. This ensures recommendations aren’t just theoretical—they’re backed by real-world behavior and user evaluations.

Key Takeaways from Testing:

• Grok-2 1212 consistently outperformed on persuasive conversations, especially in multilingual recruiting scenarios.
• GPT-4 excelled when detail and polish were required, often winning the vote when the context was complex or emotionally sensitive.
• Gemini ranked best in efficiency-focused responses, especially in short-form, high-volume follow-up threads.
• DeepSeek delivered excellent clarity, ideal for more transactional messages with precise breakdowns.

The alignment across models during blind reviews confirms that Brio’s analytical process yields reliable, repeatable results—so whichever model you choose, you can trust that it was selected based on structured, impartial testing.

5. Switching Between Models: When and Why

Brio allows you to switch models per Engagement Profile, meaning you can tailor AI behavior depending on the recipient or campaign type.

When to switch models:

• If you’re targeting new sectors or languages
• If your CTA clickthroughs drop and you need to test tone
• When scaling operations and needing faster reply generation
• For A/B testing different tones (e.g., casual vs. formal)

Example: You might create one Engagement Profile called “Candidate Outreach – Tech” using Grok-2, and another profile called “Client Prospecting – Legal” using GPT-4 for more formal, structured responses.

Summary: Making the Right Choice

Choosing the right AI provider and model inside Brio is more than a technical decision—it’s a strategic one. The nuances of your audience, tone, goals, and communication style all play a role.

If you’re just getting started or want one reliable, all-purpose performer:
Start with Grok-2 1212. It’s balanced, effective, and built for persuasive outreach at scale.

If you need highly polished, narrative-rich engagement:
Opt for GPT-4. It’s articulate and emotionally aware.

Need speed and simplicity?
Gemini is the model of choice. Great for clean, concise messaging and multi-language support.
