- Default unset agents to gpt-5.6-luna instead of gpt-4.1-mini
- Prefer gpt-5.6-luna when scaffolding OpenAI crews
- Document the new default in edge docs (en, ar, ko, pt-BR)
Agents with no MODEL / OPENAI_MODEL_NAME now fall back to gpt-5.6-luna instead of gpt-4.1-mini.
New crew and JSON crew projects pick openai/gpt-5.6-luna as the first OpenAI catalog entry.
Update the default-model note and canonical LLM examples in English, then sync ar, ko, and pt-BR.
📝 WalkthroughWalkthroughThe PR changes CrewAI’s default LLM model to ChangesLLM model update
Merge Risk: 🟡 Moderate · up to This change makes unset agents and newly scaffolded crews use gpt-5.6-luna, but the generated model is not currently supported by the runtime routing path and could cause crew execution failures. The localized guides also need their fallback wording corrected, so the PR is not merge-ready until the model support path is fixed and the documentation is updated. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@docs/edge/en/learn/llm-connections.mdx`:
- Line 13: Update the fallback note at
docs/edge/en/learn/llm-connections.mdx#L13-L13 to explain that the application
checks OPENAI_MODEL_NAME, MODEL, and MODEL_NAME before falling back to
DEFAULT_LLM_MODEL, without presenting OPENAI_MODEL_NAME as the sole default
source. Apply equivalent localized wording at
docs/edge/ar/learn/llm-connections.mdx#L13-L13,
docs/edge/ko/learn/llm-connections.mdx#L13-L13, and
docs/edge/pt-BR/learn/llm-connections.mdx#L13-L13.
In `@lib/crewai/src/crewai/constants.py`:
- Line 348: Ensure the CLI-generated model gpt-5.6-luna follows a supported
native OpenAI path by adding it to crewai.llms.constants.OPENAI_MODELS (or
upgrading LiteLLM to a version that supports it). Apply the corresponding
default-model alignment in lib/crewai/src/crewai/constants.py:348 and
lib/cli/src/crewai_cli/constants.py:355; both sites require the same
supported-routing fix.
Apply the same fix in `@lib/cli/src/crewai_cli/constants.py` at line 135.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Correct the fallback wording in every localized guide.
All four notes describe OPENAI_MODEL_NAME as the sole source of the default. The runtime also checks MODEL and MODEL_NAME, then uses DEFAULT_LLM_MODEL.

LiteLLM 1.84.8 model_cost gpt-5.6-luna GPT-5.6 support release notes
💡 Result:
LiteLLM version 1.84.8 is a maintenance release focused on database resilience and key rotation improvements, not the addition of GPT-5.6 support [1][2][3]. Support for the OpenAI GPT-5.6 family (including gpt-5.6-luna) was added in later versions of LiteLLM, specifically bundled starting with v1.93.0-dev.2 for local model cost maps [4][5]. The GPT-5.6 family was released by OpenAI on July 9, 2026 [6][7]. Key details regarding your query: LiteLLM 1.84.8 Release Notes: This version, released on June 13, 2026, primarily includes patches for database-related issues (such as Prisma reconnection and timeout controls), grace-period key rotation fixes, and streaming corrections [1][2][3]. It does not contain support or pricing for the GPT-5.6 model family [4][5]. GPT-5.6 Support: LiteLLM provides Day 0 support for the GPT-5.6 family (Sol, Terra, and Luna) [4][5]. Since v1.93.0, LiteLLM includes this metadata in its bundled model cost maps [4][5]. Users can enable cost tracking and context-window enforcement by ensuring they are running a version >= 1.93.0 or by reloading the model cost map [4][5]. GPT-5.6-Luna Pricing: In LiteLLM's model cost map, the pricing for gpt-5.6-luna is structured as follows (standard tiers, per million tokens): Input: $1.00 [4][5] Output: $6.00 [4][5] Cache Read: $0.10 [4][5] Cache Write: $1.25 [4][5] You can access these models by configuring your model_list in LiteLLM to use openai/gpt-5.6-luna [4][5]. If you are running an older version like 1.84.8, you must upgrade to at least v1.93.0 to benefit from the built-in cost tracking and metadata for the GPT-5.6 family [4][5].

Route the CLI-generated model through a supported path. The library default uses native OpenAI routing, but the CLI generates openai/gpt-5.6-luna. This model is absent from crewai.llms.constants.OPENAI_MODELS, so it falls back to LiteLLM 1.84.8, whose model map lacks it. Add the model to the native allow-list or upgrade LiteLLM.

In `@lib/crewai/src/crewai/constants.py` at line 348, Ensure the CLI-generated
model gpt-5.6-luna follows a supported native OpenAI path by adding it to
crewai.llms.constants.OPENAI_MODELS (or upgrading LiteLLM to a version that
supports it). Apply the corresponding default-model alignment in
lib/crewai/src/crewai/constants.py:348 and
lib/cli/src/crewai_cli/constants.py:355; both sites require the same
supported-routing fix.
Apply the same fix in `@lib/cli/src/crewai_cli/constants.py` at line 135.
