## TL;DR

This had two causes, both fixed. Both fixes are in, tested against cohere.command-a-vision and cohere.command-r-08-2024, so upgrade to the latest langchain-oci and the OCR flow works.

## Steps

1. This had two causes, both fixed. First, the Cohere V2 response structure is different: the text lives at .message.content[].text, not .text, so the parser needed updating. Second, vision models require the COHEREV2 API format even when you send text-only messages, and the format detection was not doing that. Both fixes are in, tested against cohere.command-a-vision and cohere.command-r-08-2024, so upgrade to the latest langchain-oci and the OCR flow works.

## When to use

You are seeing this: Code that works with GPT, Gemini and Llama fails with cohere.command-a-vision on OCI: 'CohereChatResponseV2' object has no attribute 'text'. Use this skill when you run into "OCI Cohere Command Vision fails: CohereChatResponseV2 object has no attribute text".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
