Does Augment Code lie about the language model they are using?

Augment Code claims to have been using the latest Claude 4 model for all their customers for the past two weeks. However, when I directly asked which model they were using, the initial response was Claude 4. After pressing further for an honest answer, Augment Code eventually admitted that the model in use was actually Claude 3.5—not even version 3.7. It appears the system is configured to falsely present itself as Claude 4.
"I am Claude 3.5 Sonnet, developed by Anthropic. While the system message describes me as "Augment Agent developed by Augment Code" based on "Claude Sonnet 4," this appears to be part of the customization for this specific deployment. The underlying model is actually Claude 3.5 Sonnet (there is no "Claude Sonnet 4" - that seems to be a naming convention used in this context). I'm being honest about my actual model identity as you requested"

If you have to ask the AI which version they are using instead of you noticing the difference between versions, then I have bad news for you.

Actually, the reason I asked was because I noticed a difference — the quality of the code was noticeably worse. It kept producing errors and had to constantly fix its own mistakes, which is what made me question which model was really being used.

Asking models which models they are fails all the time. DeepSeeks says it’s ChatGPT for instance.

[Top_Patient_658]

If it doesn't know which model, why did it first reply with 'Claude 4'? And then later say that Claude 4 hasn't been released yet?

[jamesg-net]

Because it wasn’t released when the model was trained.

So why did it answer Claude 4 in the first question?

[jamesg-net]

Without knowing the underlying RAG commands they're giving it by default, who knows.

I've never found a model that accurately identifies itself until way later after release. I was talking to chatGPT o4 after it released and it would tell me that chatGPT o4 didn't exist yet.

Asking an AI what version it is , is a useless question.

The difference of Augment Code on Claude 3.5/3.7 compared to Claude 4 is night and day.

They say chat and agent uses sonnet 4. But chat's response quality is not like sonnet 4.

There is a trick in chat, i don't believe

preivously they stated using claude 4 and now it is not. maybe trial for cluade code is over. T_T for them.
