+`ManagedServer` is a wrapper around `APIServer` that automatically tracks text sequences with aligned tokens and logprobs. It also exposes a normalized `get_logprobs(...)` API for backend-agnostic logprob access. This eliminates the need for manual token extraction, alignment, and masking in your environment code, making it **the recommended approach** for handling inference in Atropos environments.
 
 **Server Compatibility:** ManagedServer works with `VLLMServer`, `SGLangServer`, and `TrlVllmServer`. Simply set the `server_type` field in your `APIServerConfig` to `"vllm"`, `"sglang"`, or `"trl"` to use the appropriate backend with automatic server class selection.

+Fetch logprobs with a normalized schema that is backend-agnostic.
+
+**Args (common):**
+- `messages` or `prompt` or `input_ids`
+- `n`: Number of sampled sequences
+- `max_tokens`
+- Optional backend kwargs such as `top_k` / `top_logprobs`, `temperature`, `stop`
+
+**Returns (normalized):**
+```python
+{
+  "prompt_tokens": List[int],
+  "sequence_token_ids": List[List[int]],          # [seq][pos]
+  "sequence_logprobs": List[List[float]],         # [seq][pos]

+  "sequence_topk_logprobs": List[List[List[float]]],  # [seq][pos][k]
+  "finish_reasons": List[Any],

+```
+
+**Notes:**
+- If the backend only returns sampled-token logprobs, ManagedServer synthesizes `k=1` singleton top-k arrays.
+- This method is for transport/interface consistency; richer top-k depends on backend support.

 - Provides the same interface as `ManagedServer`
-- Returns **fixed placeholder values** for tokens and logprobs:
-  - `tokens`: `[1, 2, 3]`

-  - `logprobs`: `[-0.5, -0.5, -0.5]`
