ChatGPT 5.4 for Builders: Capability Patterns and Production Notes

When a new GPT model lands, the first wave of "what's new" coverage focuses on benchmark deltas. The second wave. the one builders actually need. is about which production patterns the model unlocks, where it changes the cost-quality calculus, and what to migr

High-Volume Classification and Extraction with Gemini Flash Lite

The two highest-volume LLM use cases in production today are classification (assign a category to an input) and extraction (pull structured fields from unstructured input). For both, small-tier models like Gemini 3.1 Flash Lite often produce identical-quality

ChatGPT 5.4: When to Use Reasoning Models vs Standard Chat

OpenAI now ships two distinct families of models for builders to choose between: standard chat models like GPT 5.4, and reasoning-tier models that produce longer, more deliberate outputs by spending more compute per request. They're not interchangeable. and ch

Gemini 3.1 Flash Lite: When Fast and Cheap Wins

The frontier-model conversation gets the headlines. The small-tier models do the work. In production AI systems with real volume, the lite-class models. Gemini 3.1 Flash Lite, Claude Haiku, GPT mini variants. handle the bulk of requests, while the frontier tie

Gemini 3.1 Pro for Builders: Strengths, Use Cases, and Production Patterns
