## Background

#12766 

we were not passing the `strict: true` mode for tools for the bedrock
and groq provider, which sometimes led to the models not adhering to the
tool input schema

## Summary

modified the api to ensure strict mode is stored and ensure it's passed
to the model tool spec

## Manual Verification

hard to verify via a cli example since behaviour can vary but ran the
following example

<Details>
<summary> repro example </summary>

```ts
import { generateText, tool } from 'ai';
import { bedrock } from '@ai-sdk/amazon-bedrock';
import { z } from 'zod';
import { run } from '../../lib/run';

run(async () => {
  const result = await generateText({
  model: bedrock('openai.gpt-oss-120b-1:0'),
  tools: {
    getWeather: tool({
      description: 'Get weather by city and unit',
      inputSchema: z.object({
        city: z.string(),
        unit: z.enum(['celsius', 'fahrenheit']),
      }),
      strict: true,
    }),
  },
    prompt: 'What is the weather in Boston?',
  });

  console.log(JSON.stringify(result, null, 2));
});
```

…12901)

## Summary

Fixes #12770

Azure AI Foundry and Mistral models deployed on Azure omit the `type`
field in streaming `tool_calls` deltas. The OpenAI chat stream parser
was throwing:

```
InvalidResponseDataError: Expected 'function' type.
```

## Root Cause

In `openai-chat-language-model.ts`, the parser checked `if
(toolCallDelta.type !== 'function')` at the start of a new tool call.
Azure / Mistral omit the `type` field entirely (it is `undefined`), so
`undefined !== 'function'` triggered the error before even reading the
function name or id.

## Fix

Changed the guard from:
```ts
if (toolCallDelta.type !== 'function') {
```
to:
```ts
if (toolCallDelta.type != null && toolCallDelta.type !== 'function') {
```

A missing `type` is now silently treated as `"function"` (the only valid
value). An explicit non-`"function"` type still throws.

## Test

Added a new streaming test case that sends tool call deltas without a
`type` field (matching Azure / Mistral behaviour) and verifies the tool
call is parsed correctly.

### Patch Changes

- 53bdfa5: fix(openai): allow null/undefined type in streaming tool call
deltas

Azure AI Foundry and Mistral deployed on Azure omit the `type` field in
streaming tool_calls deltas. The chat stream parser now accepts a
missing
    `type` field (treating it as `"function"`) instead of throwing
    `InvalidResponseDataError: Expected 'function' type.`

anthropic silently released a new code execution tool (which is
suggested for programmatic tool calling)

ref here:

## Summary

adds the new tool to the registry, updates the api schema, makes sure
the the conversion from prompts to responses is correctly mapped

…g.format (#12319)

## Background

#12298 

## Summary

- **`@ai-sdk/anthropic`**: Migrated the deprecated `output_format`
request parameter to `output_config.format`, aligning with the [current
Anthropic
API](https://platform.claude.com/docs/en/build-with-claude/structured-outputs).
The `effort` and `format` fields are now merged into a single
`output_config` object to avoid one spread overwriting the other.
- **`@ai-sdk/amazon-bedrock`**: Enabled `supportsNativeStructuredOutput:
true` for Bedrock Anthropic models. Structured outputs are now GA on
Bedrock and no longer require a beta header, so the JSON tool fallback
is no longer necessary.

## Manual Verification

verified the fix by running the following code snippet before and after
the changes

<Details> 
<summary> repro </summary>

```ts
import { bedrockAnthropic } from '@ai-sdk/amazon-bedrock/anthropic';
import { generateText, Output } from 'ai';
import 'dotenv/config';
import { z } from 'zod';
import { run } from '../../lib/run';

run(async () => {
  const result = await generateText({
    model: bedrockAnthropic('us.anthropic.claude-opus-4-6-v1'),
    output: Output.object({
      schema: z.object({
        recipe: z.object({
          name: z.string(),
          ingredients: z.array(
            z.object({
              name: z.string(),
              amount: z.string(),
            }),
          ),
          steps: z.array(z.string()),
        }),
      }),
    }),
    providerOptions: {
      anthropic: {
        structuredOutputMode: "outputFormat",
        thinking: { type: "adaptive" },
        effort: "low",
      },
    },
    prompt: 'Generate a lasagna recipe.',
  });

  console.log('Recipe:', JSON.stringify(result.output, null, 2));
  console.log();
  console.log('Finish reason:', result.finishReason);
  console.log('Usage:', result.usage);
});
