Models

TokOne supports the full Claude, ChatGPT, Gemini and other model lineups (OpenAI's GPT, Codex, and Image series; Anthropic's full Claude series; Google's full Gemini series, and more). No monthly fee, no minimum spend — billed by actual token usage in real time, with prices tracking upstream official changes. See Pricing for the full rules.

Get the authoritative live list

The table below lists mainstream models only. To see which models your key can call right now, hit the endpoint:

curl https://api.tokone.ai/v1/models \
  -H "Authorization: Bearer $TOKONE_API_KEY"

The response matches OpenAI's GET /v1/models structure.

Anthropic Claude

Model	model value	Context (in / out)
Claude Opus 4.7 (strongest reasoning)	claude-opus-4-7	1 M / 128 K
Claude Opus 4.6	claude-opus-4-6	1 M / 128 K
Claude Sonnet 4.6	claude-sonnet-4-6	1 M / 64 K

• gpt-5.5 and gpt-5.4 use /v1/chat/completions, and also support /v1/responses — clients written for the Responses API (such as Codex CLI) use /v1/responses automatically.
• Claude models use the Anthropic-compatible /v1/messages; Gemini models use the Google-compatible /v1beta.
• Models not listed above (older versions, smaller variants) are callable too; the authoritative list is GET /v1/models and the console.

How to choose

Use case	Recommended
Default / primary: long-form writing, complex reasoning, code review, agent orchestration	gpt-5.5 / claude-opus-4-7
High-frequency chat, support bots, bulk translation (cost-sensitive)	gpt-4o-mini / gemini-3.5-flash
In-IDE autocomplete, Codex CLI, code rewriting	gpt-5.5
Very long context, large-scale document processing	gemini-3.5-flash

WARNING

Model IDs must match upstream. If a call returns 404 or "model unavailable," check GET /v1/models first to confirm the model is currently listed.
