The PM's Guide to AI Models
Match Capabilities to User Needs, Not Benchmarks 🎯
"Which AI model should we use?"
It's the question that can make product leaders break into a cold sweat. With new models launching weekly and each vendor claiming superiority, the decision feels increasingly high-stakes and complex.
But here's what most benchmark comparisons won't tell you: the "best" AI model depends entirely on your specific product context, user needs, and business constraints.
This guide cuts through the technical jargon to deliver what product managers actually need: a strategic framework for choosing models that create genuine user value rather than just impressive demos.
Understanding AI Models: The Basics 🧠
AI models are computational frameworks designed to perform specific tasks by learning from data. At their core, they're defined by their ability to autonomously make decisions or predictions without explicit programming.
Example: Email Spam Filter
An AI model can be trained on thousands of labeled emails (spam vs. not spam). Over time, it learns patterns — like certain keywords, sender domains, or formatting — that are common in spam. Once trained, the model can predict whether a new incoming email is spam without being explicitly told the rules. So, instead of writing hard-coded rules like "If subject contains 'free money', mark as spam," the AI model learns those rules automatically from data.
The Model Landscape: A Strategic Framework 🧩
Let's reframe how we think about AI models—not as technological novelties, but as strategic assets with distinct strengths, limitations, and optimal applications.
Foundation Models: The Versatile Workhorses 🏗️
Foundation models are large, general-purpose AI systems trained on massive datasets that serve as the base layer for many AI applications. These "base models" can be adapted across diverse domains.
Examples: OpenAI's GPT family, Google's Gemini, Meta's Llama, Anthropic's Claude
Strategic value: These models deliver immediate business impact through versatility and broad knowledge. They excel at:
Content generation at scale
Customer engagement automation
Knowledge extraction from unstructured data
Rapid prototyping of AI capabilities
When to deploy: When you need to quickly implement AI capabilities that address multiple business functions without specialized training.
Reasoning Models: The Strategic Advisors 🧩
Reasoning models are fine-tuned to think through problems step-by-step, offering more reliable analysis for complex decisions.
Examples: OpenAI's o-series, Google's Gemini 2.5, Anthropic's Claude 3.7 Sonnet
Strategic value: These models transform decision-making processes through:
More reliable analysis of complex scenarios
Reduced hallucinations in critical applications
Enhanced problem-solving capabilities
Better handling of nuanced queries
When to deploy: For high-value, complex business processes where accuracy trumps speed—contract analysis, investment decisions, risk assessment, and strategic planning.
Multimodal Models: The Information Integrators 🌐
Multimodal models process multiple data types (text, images, audio, video) simultaneously, breaking down information silos.
Examples: OpenAI's GPT-4o, Google's Gemini family, Meta's Llama 4
Strategic value: These models unlock previously inaccessible insights by:
Analyzing diverse document formats (PDFs, spreadsheets, presentations)
Enabling visual analysis alongside text understanding
Creating cohesive experiences across communication channels
Handling rich media content seamlessly
When to deploy: When your business processes involve multiple data formats or when creating customer experiences that bridge visual and textual information.
Open vs. Closed Models: The Resource Equation ⚖️
This fundamental choice determines the balance between control, cost, and capability.
Open source models provide freedom, transparency and customization at the cost of implementation complexity.
Closed models offer cutting-edge capabilities and support, but with less flexibility and higher ongoing costs.
Strategic consideration: This decision should align with your:
Technical resources and AI expertise
Data privacy requirements
Customization needs
Budget constraints
Time-to-market priorities
AI Model Innovations Reshaping the Landscape 🔥
Google's Gemini 2.5 Pro Hits Top Spot on AI Leaderboards 🏆
The News: Google has previewed Gemini 2.5 Pro I/O Edition, showcasing major improvements in frontend coding, UI design, and agentic automation — and launching it straight to the top of multiple AI leaderboards.
The details:
Gemini 2.5 Pro now holds the top position on WebDev Arena, with an Arena Score of 1419.95 — well ahead of Claude 3.7 Sonnet (1357.10) and GPT-4.1 (1261.35)
The model offers dramatic performance gains in code refactoring, code transformation, UI workflows, and agent-based tools tailored for developers
Video understanding features scored 84.8% on the VideoMME benchmark, enabling interactions like transforming educational video content
Why it matters: With its release preceding I/O, Google continues to prioritize developer performance over marketing fanfare. DeepMind's CEO now calls this the best coding model Google has ever built. The model's +147 Elo leap is a clear signal: developers prefer its outputs by a wide margin in real-world coding use cases.
HeyGen Adds Expressive Realism to Avatar Animation 🗣️
The News: HeyGen just launched Avatar IV, its most advanced avatar animation model yet — blending facial expressiveness and vocal realism using just a single photo.
The details:
Powered by a diffusion-based voice-to-expression engine, the model maps vocal tones and scripts to realistic facial motion, gestures, and micro-expressions
Works from one photo (even side profiles) and supports subjects ranging from pets to anime characters
Format versatility includes portraits, half-body, and full-body avatars
Built for influencer-style UGC, singing avatars, video podcasts, and AI-enhanced gaming characters
Why it matters: HeyGen is setting a new bar for avatar realism, pushing beyond traditional talking heads. Avatar IV empowers creators with expanded camera support and dynamic body formats — enabling expressive content like virtual hosts, animated pets, and custom in-game characters.
Lightricks Unveils Lightning-Fast Video Model 🎥
