⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

Verify gpt-5.1 model metadata in OpenAI constants.

Ensure that "gpt-5.1" has been properly registered in src/backend/base/langflow/base/models/openai_constants.py with the correct metadata (reasoning, tool_calling flags, etc.). Based on prior learnings, GPT-5 series models are reasoning models, so verify that gpt-5.1 is correctly configured.

🏁 Script executed:

#!/bin/bash
# Verify gpt-5.1 is registered in openai_constants.py

fd -t f "openai_constants.py" | head -1 | xargs grep -n "gpt-5.1" || echo "gpt-5.1 not found in openai_constants"
fd -t f "openai_constants.py" | head -1 | xargs grep -A 2 -B 2 "OPENAI_REASONING_MODEL_NAMES\|OPENAI_CHAT_MODEL_NAMES" | head -30

Length of output: 37

Verify and register gpt-5.1 in openai_constants.py with correct metadata.

GPT-5.1 was released today and is available in the API platform with support for tool calling. However, the script output confirms "gpt-5.1 not found in openai_constants", indicating this model is missing from the codebase even though it's referenced in the JSON starter project.

GPT-5.1 delivers improved reasoning, making it a reasoning model. Based on prior learnings about GPT-5 series configuration, gpt-5.1 should be:

  • Added to OPENAI_REASONING_MODEL_NAMES with reasoning=True
  • Configured with tool_calling=True (since GPT-5.1 has similar training for tool calling)

Register the model in src/backend/base/langflow/base/models/openai_constants.py following the pattern from prior GPT-5 additions (PR #9336), then verify it appears in the dropdown when the JSON starter project loads.

🤖 Prompt for AI Agents 
In src/backend/base/langflow/initial_setup/starter_projects/Research Agent.json
around line 2975 the file references "gpt-5.1" but the model is not registered
in src/backend/base/langflow/base/models/openai_constants.py; add an entry for
"gpt-5.1" following the existing GPT-5 additions (see PR #9336): register it in
the model metadata dict(s) with reasoning=True and tool_calling=True, include it
in OPENAI_REASONING_MODEL_NAMES, and add it to any global OpenAI model lists
(e.g., ALL_OPENAI_MODELS or TOOL_CALLING_MODELS) so the loader recognizes it and
it appears in the dropdown when the starter project is loaded.
