Context and output limits
Not documented for Sonnet 5.5
We will update this page when official documentation changes and verify EvoLink access separately. Before API access is offered, the route, supported model ID, request behavior, and billing must be confirmed.
What to check before using Sonnet 5.5
Use these checks when access is announced. Your current coding or agent workflow remains the baseline until the new route meets your requirements.
Confirm the API route and model ID
Check the official identifier, then confirm the model ID and request controls supported by EvoLink. A page URL or a provider announcement alone is not enough to configure a request.
Check pricing and cache terms
Review the confirmed input, output, and cache rates for the route you will use. Budget from those terms instead of carrying over Sonnet 5 prices or assuming an Opus 5.5 discount.
Test your coding or agent workflow
Once access is verified, replay a small set of representative tasks. Check accepted outputs, tool behavior, latency, and total billed cost including retries before switching production traffic. Keep your current configuration ready for rollback.

Claude models to evaluate while you wait
If you need an API today, review an available model’s own pricing and integration guidance through EvoLink. Sonnet 5 and Opus 5.5 have separate capabilities and prices; neither establishes what Sonnet 5.5 will offer.

Is the Claude Sonnet 5.5 API available on EvoLink?
EvoLink access has not been verified. This availability page does not expose a callable Sonnet 5.5 route. Check back for an explicit availability update before integrating it.
What is the Claude Sonnet 5.5 API model ID?
The official model directory checked on September 27, 2026 does not list a Sonnet 5.5 API identifier. Do not infer a request ID from this page’s URL or another Claude model’s naming pattern.
What does Sonnet 5.5 cost?
The checked official price list does not publish Sonnet 5.5 pricing, and no EvoLink price is confirmed here. Prices for Sonnet 5 or Opus 5.5 are separate reference-model prices.
What is the Sonnet 5.5 context window?
A Sonnet 5.5 context window and output limit have not been confirmed in the checked official documentation. Plan against the limits of the model you currently use; Sonnet 5 limits are not Sonnet 5.5 specifications.
Can I join an early-access program here?
You can subscribe to availability updates on this page, but subscribing does not grant or reserve early access. You can also read the release watch or evaluate an existing Claude model through its model page.
Will an Anthropic release make it available through EvoLink immediately?
Provider release and EvoLink access are separate states. EvoLink availability requires a verified route, supported request behavior, and confirmed billing before this page can offer integration.
Can I switch by changing only the model ID?
A configurable model ID makes evaluation easier, but it does not prove request compatibility. Check the new model’s documented controls, response handling, tools, and route behavior before changing production traffic.
