GPT-6 Astra
OpenAI shows few-shot examples in a developer message so a model can infer the desired classification or response pattern from demonstrations.
AI Prompt
A reference directory for comparing practical prompt-design marks across current model families. It organizes reusable prompt patterns, chaining methods, evaluation habits, and failure checks around official model documentation so readers can distinguish a template pattern from a tested workflow or a known anti-pattern.
| Model | OEM reference | Part number | Price | Fact | Source |
|---|---|---|---|---|---|
| GPT-6 Astra | Structured Outputs with JSON Schema | OpenAI documents Structured Outputs as a way to constrain supported model responses to a supplied JSON Schema instead of relying only on free-form formatting instructions. | https://developers.openai.com/api/docs/guides/structured-outputs | ||
| GPT-5.5 | Few-shot input/output examples | OpenAI's prompt-engineering guide describes few-shot learning as steering a task with a small set of representative input and output examples. | https://developers.openai.com/api/docs/guides/prompt-engineering | ||
| Claude Opus 5 | XML-tag prompt structure | Anthropic recommends descriptive XML tags to separate instructions, context, examples, and other prompt sections when complex prompts need clearer structure. | https://docs.anthropic.com/en/docs/build-with-claude/prompt-engineering/prompt-templates-and-variables | ||
| Gemini 2.0 Flash | Vertex AI system instructions | Google documents system instructions as model-level guidance for behavior, persona, context, and response formatting before user prompts are processed. | https://cloud.google.com/vertex-ai/generative-ai/docs/learn/prompts/system-instruction-introduction |
OpenAI shows few-shot examples in a developer message so a model can infer the desired classification or response pattern from demonstrations.
Anthropic describes explicit prompt chaining as useful when intermediate results must be inspected, including a self-correction pattern of draft, review against criteria, and refinement.
OpenAI describes an eval workflow as defining the task, running it on test inputs, analyzing results, and iterating on the prompt.
OpenAI lists vibe-based evaluation, overly generic metrics, biased eval datasets, and ignoring human feedback among evaluation anti-patterns.
