Four LLMs, six SQL tasks, one PostgreSQL schema. GPT-4o-mini led with 9 wins over Claude Sonnet 4.5, GPT-4o, and Gemini 2.5 Flash. Here's the full breakdown.
We ran 5 developer tasks through DeepSeek V4 Pro, GPT-5.5, Opus 4.7, and Llama 4. V4 Pro beats GPT-5.5 while costing 4.5x less, but latency averages 28 seconds.
Prompt caching cuts LLM costs 90% on Anthropic and 50% on OpenAI, but only when your workload fits. Here's the exact break-even math per provider.
The exact token-to-word and token-to-character conversion rates for English, code, and non-English LLM input, plus a practical counting recipe.
OpenAI's GPT-5.5 brings a 1M-token context and native computer use to the frontier, at double GPT-5.4's price. Here's what actually changed.
Opus 4.7 scores higher on coding benchmarks and adds 3.75MP vision, but its new tokenizer inflates real cost by up to 35%. Here's what changed.
Your OpenAI bill isn't just input + output tokens. Thinking tokens, JSON retries, and prompt bloat quietly triple costs. Here's how to spot each one in your own app.
