Greptile SummaryThis PR adds a model catalogue and discovery system to the PraisonAI CLI, introducing
Confidence Score: 3/5Safe to merge for users who never opt into validate_model=True; the credential-validation path has a logic error that discards a valid API key silently when a stored model fails validation. The credential fallback loop in env.py resets api_key to None when a stored credential's model is invalid, then continues searching other providers. If no alternative credential exists the function returns unauthenticated, so the caller receives an opaque auth error rather than the intended model-validation message. Because validate_model defaults to False this doesn't affect the common path, but it is a real defect in the opt-in flow that inverts the expected user experience. src/praisonai/praisonai/llm/env.py — the fallback credential validation block (lines 144-153) needs the api_key discard logic corrected before validate_model=True can be safely used by callers.

"o1" in model_id will match any model ID that happens to contain the two-character string o1 — including hypothetical IDs like provider/model-v1.0 or tool-o1-compat. More practically, OpenAI's o1 and o1-mini models now support tool calling in newer API versions, so supports_tools = not any(x in model_id for x in ["o1", ...]) will incorrectly flag those as incapable, leading to spurious warnings. These heuristics will drift further as providers update capabilities. Using litellm's supports_function_calling or supports_vision metadata keys from model_cost would be more reliable.

Skip catalogue validation for YAML-local model aliases.

litellm model_list callable API documentation
💡 Result:
In LiteLLM, the model_list parameter used in the Router class is a static configuration list of model deployments, not a callable API [1][2][3]. It is defined as a list of dictionaries, where each dictionary specifies a model deployment with its associated configuration parameters (e.g., model name, API keys, and other provider-specific settings) [1][2]. Key characteristics of model_list: - Structure: It expects a List[Dict] or List[DeploymentTypedDict] [2][3]. - Purpose: It enables load balancing and routing by mapping a single model alias (model_name) to multiple backend deployments [1][2][4]. - Implementation: When initializing the Router, you pass this list directly [1][5]: router = Router(model_list=[...]) If you are looking for dynamic or callable functionality in LiteLLM, this is typically associated with callbacks (e.g., custom logging or observability), not the model_list itself [6][7][8]. You can add callbacks using callable objects to handle events like success or failure during model calls [7][8]. If you need to dynamically fetch or manage available models, you should look into utilities like litellm.utils.get_valid_models or managed proxy configurations, rather than treating the model_list as a callable [9][10].

@claude You are the FINAL architecture reviewer. If the branch is under MervinPraison/PraisonAI (not a fork), you are able to make modifications to this branch and push directly. SCOPE: Focus ONLY on Python packages (praisonaiagents, praisonai). Do NOT modify praisonai-rust or praisonai-ts. Read ALL comments above from Gemini, Qodo, CodeRabbit, and Copilot carefully before responding. Phase 1: Review per AGENTS.md
Phase 2: FIX Valid Issues Phase 3: Final Verdict |

- Fix TypeError: model_list is a list attribute not callable in litellm - Change validate_model default to False to preserve backward compatibility - Move model validation before provider resolution to ensure correct key/base selection - Add validation for fallback models from stored credentials - Skip catalogue validation for local YAML model aliases - Ensure consistent JSON output in CLI when litellm unavailable Co-authored-by: Mervin Praison <MervinPraison@users.noreply.github.com>

@claude dont you think this need to come from coresdk, so don't you think we need to do this via core sdk ? |

Final Verdict✅ APPROVED - The model catalogue feature is correctly implemented in the wrapper layer per architecture guidelines. All critical issues have been resolved. The PR maintains backward compatibility and follows protocol-driven design principles. |
…dlers - Add explicit typer.Exit handlers in describe_model and validate_model commands - Re-raise typer.Exit to avoid spurious error messages when models are not found - Preserve exception context with 'from e' for better debugging

There was a problem hiding this comment.
When a stored credential's model string fails validation, the code resets api_key = None and continues to the next provider. If no subsequent provider credential exists, resolve_llm_endpoint returns with api_key=None — the caller then hits an authentication failure with no indication that a model-validation problem was the root cause.
A user who stored ft:gpt-4o:myorg:abc123 (a fine-tuned model, absent from the catalogue) would silently lose their API key and receive a confusing auth error instead of the intended "Unknown model" message. The correct behavior is to raise the ValueError immediately so the validation error is surfaced, or to keep the api_key and fall back to the primary model string.

Fixes #2123
Summary
Adds a comprehensive model discovery and validation system to the PraisonAI CLI, addressing the core "few lines to first success" gap where users previously had to guess model identifiers.
