After an initial period where Chat Playground worked well, living up to its presentation and expectations, the quality of its services has gradually deteriorated. Today, it has become practically unusable, if not completely, at least for the most part.

I'm talking about the level of the AI models provided, which has been silently downgraded step by step. Now, the specific versions of the AI models have been replaced by a generic "latest model" label. In reality, this is just a vague description masking a total downgrade.

To be clear: previously, you could select and use Claude Sonnet or even Opus. Now, hidden under the "latest model" label, you get Claude Haiku 3.5. So, not only is it the lowest tier available, but it's even an obsolete version.
