OpenRouter pricing guide
GPT-5.5 on OpenRouter: pricing, model ID, context window
Use this GPT-5.5 OpenRouter guide to check pricing, model ID, context window, and when to choose OpenRouter, GitHub Copilot, Vercel, OpenCode, or Venice.
Original whichllm buying guide based on Search Console demand for GPT-5.5 OpenRouter pricing, model ID, context window, and coding-tool routes.
TL;DR
- Start with OpenRouter when you need one API key, visible GPT-5.5 pricing, and the model ID
openai/gpt-5.5. - Use GitHub Copilot when GPT-5.5 is mainly for IDE coding and seat-based workflow matters more than token accounting.
- Use Vercel AI SDK routes when your app already runs on Vercel and deployment friction matters as much as raw token price.
- Use OpenCode or Venice when you are testing coding-agent routes or privacy/workflow tradeoffs before production wiring.
The quick answer for GPT-5.5 on OpenRouter
| Question | Answer | What to check live |
|---|---|---|
| Model ID | openai/gpt-5.5 | Confirm the exact OpenRouter model ID before shipping config. |
| Context window | Check live route | Context and limits can differ by provider route and should be verified on the model page. |
| Input/output price | Check live route | Use the OpenRouter GPT-5.5 page as the current pricing source before budgeting. |
| OpenCode config | provider: openrouter | Use model openai/gpt-5.5, then run your actual coding prompt pack. |
Best GPT-5.5 route by workload
| Workload | First route to test | Why |
|---|---|---|
| API pricing comparison | OpenRouter | It is the fastest way to inspect GPT-5.5 pricing, model ID, and fallback options from one API surface. |
| IDE coding | GitHub Copilot | Choose it when seat-based coding workflow matters more than per-token cost visibility. |
| Vercel app | Vercel AI SDK | Use it when GPT-5.5 should sit inside an existing Vercel deployment path. |
| Agent CLI testing | OpenCode | Use it to test GPT-5.5 inside a coding-agent loop before deciding on production routing. |
| Alternative provider check | Venice | Compare when privacy, account setup, or provider terms matter as much as the headline route. |
Do not copy stale GPT-5.5 prices
Searchers ask for OpenRouter GPT-5.5 pricing because the route is already visible in Google, but token prices, context limits, and model IDs can change faster than static articles. Treat this page as the decision map, then use the linked model pages as the live source before committing code or budget.
The practical buying test is simple: run the same coding task, long-context task, and structured extraction task through OpenRouter and one tool-native route. Track total cost, latency, retry count, and whether the answer shape stays stable.
