WindsurfAPI 3.9.24–3.9.26: safer OpenAI-compat proxy, real aborts, stricter defaults, and saner token handling

WindsurfAPI’s 3.9.24–3.9.26 patches harden its OpenAI-compatible proxy with metadata filtering, true client aborts, stricter defaults, and robust token parsing.

In v3.9.24, the proxy stops leaking Cascade panel-state frames to clients like Cursor, stabilizes /v1/models timestamps, and makes unsupported logprobs a clear 400 instead of silently succeeding. It also stamps service_tier on chat completions and keeps ACU decoding opt-in.

v3.9.25 makes non-streaming routes actually abort upstream work on client disconnect (messages, Gemini, responses). It aligns the default model to claude-sonnet-4.6 and clarifies that no key still means 401 unless explicitly allowed.

v3.9.26 fixes token paste classification to avoid misrouting secrets through RegisterUser, surfaces real error messages instead of a generic “Add failed,” and prevents a 401 from blanking the account list.

[ WHY_IT_MATTERS ]
01.

Stricter behavior (metadata filtering, logprobs 400, fail-closed auth) reduces accidental data exposure and mismatched client expectations.

02.

Real upstream aborts cut wasted compute when clients disconnect mid-request.

[ WHAT_TO_TEST ]
  • terminal

    Simulate client disconnects on non-streaming /messages, Gemini, and /v1/responses and verify upstream is aborted promptly.

  • terminal

    Send non-default logprobs/top_logprobs and confirm 400; validate model list timestamps stay stable across polling.

[ BROWNFIELD_PERSPECTIVE ]

Legacy codebase integration strategies...

  • 01.

    Audit clients relying on silent logprobs behavior or legacy Completions streaming; fix any assumptions that now error.

  • 02.

    Confirm deployments aren’t assuming empty API_KEY means open access; recheck default model resolution and strict model mapping.

[ GREENFIELD_PERSPECTIVE ]

Fresh architecture paradigms...

  • 01.

    Start with fail-closed auth and strict model mapping; prefer claude-sonnet-4.6 for default alignment.

  • 02.

    Keep ACU decoding off unless you set explicit billing tags and need usage telemetry.
