For most beginners, the best start costs nothing. ChatGPT Free has had unlimited text chat since August 2026, and Claude Free includes Anthropic's Sonnet model. Use them for a few weeks before paying. If you are building something and paying per token, Claude Haiku 5.5 or GPT-6 Luna at $0.10 per million input tokens are cheap enough to experiment freely, and Claude Sonnet 5.5 is the step up once you can feel the limits.
The safest this comparison default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
Claude Haiku 5.5 is the strongest answer here for this comparison — pick it when quality of output matters more than the $0.10/1M/1M input you pay for it.
Claude Sonnet 5.5 is the cheaper way in for this comparison, at $2.00/1M/1M input against Claude Haiku 5.5's $0.10/1M/1M.
GPT-6 Luna is the fastest of these for this comparison — worth it when latency is what the reader notices, not the last few points of reasoning depth.
Free tiers are good enough to learn on: ChatGPT Free has unlimited text chat, and Claude Free includes Sonnet.
On the API, Claude Haiku 5.5 and GPT-6 Luna cost $0.10 per million input tokens — cheap enough to practise freely.
Claude Sonnet 5.5 is the natural upgrade once a cheaper model's answers start to feel thin.
Beginners should optimise for repetition, not prestige — the model you use often teaches you the most.
If you are learning with your own money, price and speed matter because they affect how often you practise.
Move to a stronger model only when you can clearly see where the cheaper one falls short.
Switch the scoring lens to see whether the this comparison answer changes when cost, speed, or long-document depth leads the decision.

Scores out of 100 — how we evaluate models. “Est. month” is 10M in / 2M out at list price: a ceiling, no discounts.
Why each one is on the shortlist for this comparison, what it is genuinely good at, and where we would steer you away from it.
Ranked first here for this comparison: 86/100 on coding, with the widest margin of anything in this line-up.
Anthropic's October 7, 2026 low-cost model and the first Haiku with adjustable reasoning effort — thinking can be switched off for simple requests or raised to max, at $0.10/$0.50 per 1M under 100K input tokens.
Your prompts routinely exceed 100K tokens, where the price quintuples, or the task needs sustained reasoning that Sonnet 5.5 handles far better.
The cheapest way to put an Anthropic model in a high-volume pipeline. Keep requests under 100K tokens to stay on the low rate, and set effort per task — at low effort it is a fast classifier, at max it handles real tool-use work.

The fastest model in this shortlist for this comparison. Pick it when turnaround is what your readers or users notice.
OpenAI's September 22, 2026 low-cost reasoning model, replacing GPT-5.6 Luna at $0.10/$0.50 per 1M — half the predecessor's price, with the same 1.05M context.
You are choosing a budget model from scratch — Claude Haiku 5.5 costs the same and scores higher on Artificial Analysis's index.
A cheaper Luna rather than a smarter one. At $0.10/$0.50 it matches Claude Haiku 5.5 on price, but independent scoring puts Haiku 5.5 slightly ahead; choose Luna when you are already on the OpenAI stack.

Usually no. Beginners learn faster when the model is cheap enough to use often, then upgrade once the quality gap becomes obvious.
Price, speed and the main thing you want to do. Context window and edge-case quality matter more once your work gets more advanced.
