We hosted the first Vibe Coding Olympics

Last week, we hosted the first-ever Vibe Coding Olympics in the heart of New York City: a three-round, aggressively time-boxed hackathon where the deciding score was whether what teams shipped felt good to use. Prompting used to be the hard part. Now the hard part is deciding

Benchmarking Gemini 3.1 Pro: Latency, cost, and reasoning trade-offs

Google's Gemini 3.1 Pro represents a meaningful step forward for developers building applications that require advanced reasoning. Announced in February 2026, the model is positioned around stronger problem-solving without forcing teams to pay more for the privilege. At PromptLayer, where teams manage prompts and evaluate model

How do you observe LLM systems in production?

Deploying LLMs is only half the battle — once live, they can hallucinate, drain budgets, or slow down in ways standard monitoring never catches. LLM observability connects inputs, outputs, latency, cost, and quality into a single picture.

Is Opus smarter than Sonnet? Opus vs. Sonnet

The question of which AI model is "smarter" depends on what you need that intelligence to do. At PromptLayer, we spend a lot of time comparing how different models behave across real prompts, agents, and production workflows. Both models come from Anthropic's Claude family, but they
