61753c3: ###
@ai-sdk/openai: remove redundantnameargument fromopenai.tools.customTool()openai.tools.customTool()no longer accepts anamefield. the tool name is now derived from the sdk tool key (the object key in thetoolsobject).migration: remove the
nameproperty fromcustomTool()calls. the object key is now used as the tool name sent to the openai api.before:
tools: { write_sql: openai.tools.customTool({ name: 'write_sql', description: '...', }), }
after:
tools: { write_sql: openai.tools.customTool({ description: '...', }), }
@ai-sdk/provider-utils:createToolNameMapping()no longer accepts theresolveProviderToolNameparameterbefore: tool name can be set dynamically
const toolNameMapping = createToolNameMapping({ tools, providerToolNames: { "openai.code_interpreter": "code_interpreter", "openai.file_search": "file_search", "openai.image_generation": "image_generation", "openai.local_shell": "local_shell", "openai.shell": "shell", "openai.web_search": "web_search", "openai.web_search_preview": "web_search_preview", "openai.mcp": "mcp", "openai.apply_patch": "apply_patch", }, resolveProviderToolName: (tool) => tool.id === "openai.custom" ? (tool.args as { name?: string }).name : undefined, });
after: tool name is static based on
toolskeysconst toolNameMapping = createToolNameMapping({ tools, providerToolNames: { 'openai.code_interpreter': 'code_interpreter', 'openai.file_search': 'file_search', 'openai.image_generation': 'image_generation', 'openai.local_shell': 'local_shell', 'openai.shell': 'shell', 'openai.web_search': 'web_search', 'openai.web_search_preview': 'web_search_preview', 'openai.mcp': 'mcp', 'openai.apply_patch': 'apply_patch', } }); -
8359612: Start v7 pre-release
-
04e9009: chore: make provider implementations code patterns more consistent, including renaming certain exported symbols
For all externally exported symbols that were renamed, the old names continue to work via deprecated aliases.

b3976a2: Add workflow serialization support to all provider models.
@ai-sdk/provider-utils: NewserializeModel()helper that extracts only serializable properties from a model instance, filtering out functions and objects containing functions. Third-party provider authors can use this to add workflow support to their own models.All providers:
headersis now optional in provider config types. This is non-breaking — existing code that passesheaderscontinues to work. Custom provider implementations that construct model configs manually can now omitheaders, which is useful when models are deserialized from a workflow step boundary where auth is provided separately.All provider model classes now include
WORKFLOW_SERIALIZEandWORKFLOW_DESERIALIZEstatic methods, enabling them to cross workflow step boundaries without serialization errors. -
