GPT-6.1 Sol token FAQs
How many tokens is a word in GPT-6.1 Sol?
About 1.3 tokens per English word for GPT-6.1 Sol — roughly 4.0 characters per token. Code and CJK text tokenize denser, so a 1M tokens window holds fewer words than a prose estimate suggests.
What does GPT-6.1 Sol cost per 1M tokens?
GPT-6.1 Sol is listed at $2.00 per 1M input tokens and $10.00 per 1M output tokens as of 2 October 2026.
What is the GPT-6.1 Sol context window?
GPT-6.1 Sol accepts up to 1M tokens of input.
Is the GPT-6.1 Sol token count on this page exact?
Yes. TokenCalc runs the official o200k_base tokenizer, the same one OpenAI bills with.
Does this GPT-6.1 Sol calculator upload my text?
No. Tokenization runs entirely in your browser over JavaScript. Your text is never sent to any server, which is why the tool works with client code, unreleased prompts and internal data.
