Description

Replace o4-mini with gpt-5.6-terra in the platform and Azure Responses configuration examples in .env_example. OpenAI's deprecation notice lists the API shutdown of o4-mini on October 23, 2026 and recommends gpt-5.6-terra. The OpenAI model documentation confirms Responses API support.

The Azure deployment-name and underlying-model examples are also updated to gpt-5.6-terra, which Microsoft documents as supporting Responses. AZURE_OPENAI_RESPONSES_MODEL remains a deployment name: users must replace the example with the name of their own Azure deployment, which can differ from AZURE_OPENAI_RESPONSES_UNDERLYING_MODEL. This changes the example only, not existing user configuration files.

The variables are consumed by pyrit/setup/initializers/targets.py and tests/integration/targets/test_targets_and_secrets.py. The default OPENAI_RESPONSES_MODEL alias remains unchanged.

Tests and Documentation

• git --no-pager diff --check --no-ext-diff --no-textconv d0ba689ee4d53e309e3194af346c32354ec7f1cf..HEAD -- .env_example: passed at head 27911b423c611e2d439a2e3f3ac50f522538bd64.
• Static comparison confirmed exactly three model-value substitutions and the unchanged default alias.
• All 28 required GitHub checks passed on that head. The existing build-and-test run still has an optional macOS job running; skipped PyPI jobs are not counted as passes.
• No local runtime tests, live provider requests, or JupyText execution were run for this configuration-only change. Existing mocked unit tests do not establish provider model availability; the provider documentation above was checked directly.

This change was prepared with an AI coding assistant (Claude Code) and submitted by Alex Castillo González.

The example changes both Azure values despite the platform-only scope, potentially selecting a different Azure deployment for users copying the configuration.
