Pro tips for each
Claude
Long context · Reasoning · Coding
Low burn
Token-efficient; free tiers go a long way

Put standing context in a Project: upload reference files and write project instructions once, so you stop pasting the same background into every chat.
Match the model to the job: Haiku 4.5 for quick, cheap tasks, Sonnet 5.5 for everyday work and coding, Opus 5.5 or Fable 5.1 only for the hardest multi-step problems. On the API, Haiku costs $1/$5 per million tokens against $10/$50 for Fable.
Ask for the format you want up front ("Answer in 5 bullets, no preamble"). Shorter outputs cost fewer tokens and are easier to check.

Fill in Custom Instructions (Settings → Personalization) with who you are and how you want answers. It applies to every chat, so you stop repeating it.
Use the fast default model for everyday writing and questions, and switch to a Thinking model only for multi-step reasoning, analysis or code that must be right.
Keep related work in a Project so files and instructions stay together across chats.
