Frontier Models Compared on Real Work, Not Leaderboards

Questions, Reviews & Tips for Frontier LLMs & Chat Models Tools

The frontier tier changes every few months and the ranking depends heavily on what you are asking it to do. This category is where members compare on their own work rather than on leaderboards.

Threads cover head to head results on specific task types, reasoning performance on multi-step problems, long context behaviour and where quality degrades, instruction following and how each model handles constraints, refusal patterns, and cost per token at real usage volumes.

The distinction between API and chat interface access comes up often and is frequently missed. The same model can behave differently depending on system prompt, temperature and interface defaults, and comparisons that ignore this produce misleading conclusions.

Post your prompt and your evaluation criteria alongside your result. It makes the comparison reproducible, which almost nothing else in this space is. See AI Tools & Chatbots for the product view and Models & Research for the research literature.
