Fixes #7455

Summary

Register deepinfra in OPENAI_COMPATIBLE_PROVIDERS and the routing tables in llm.py, so LLM(model="deepinfra/<org>/<model>") routes natively with DEEPINFRA_API_KEY and no LiteLLM install. Same shape as #5042 and the Eden AI PR #7049, no new module or dependency.

llm = LLM(model="deepinfra/deepseek-ai/DeepSeek-V4-Flash-0731")
  • base URL https://api.deepinfra.com/v1/openai, DEEPINFRA_BASE_URL overrides it
  • DeepInfra model ids are org/model, so the pattern check requires both segments and the part after deepinfra/ reaches the API unchanged (all 191 ids in our public catalog have this form)
  • docs accordion added in en, ar, ko and pt-BR - code blocks identical, only prose translated

Before this, deepinfra/... strings fell through to LiteLLM and without crewai[litellm] installed the constructor raises ImportError.

Verification

  • Tests added or updated for the changed behavior

  • Relevant tests and quality checks pass locally

  • uv run pytest lib/crewai/tests/llms/openai_compatible -q - 55 passed (11 new: registry config, factory routing, DEEPINFRA_BASE_URL override, explicit provider="deepinfra", missing key error, model id pattern)

  • uv run ruff check and uv run ruff format --check on the changed files - clean

  • uv run mypy lib/crewai/src/crewai/ - no new errors in the changed files, only the pre-existing import-not-found noise from optional extras

  • live against api.deepinfra.com with deepseek-ai/DeepSeek-V4-Flash-0731 through the new prefix and through custom_openai=True: plain completion, tool call with function execution, JSON-schema response_format, streaming with usage in the final chunk - all pass

  • branch is rebased on current main

Additional context

Behaviour change: deepinfra/... model strings previously routed through LiteLLM, now they route natively. LLM(..., is_litellm=True) keeps the LiteLLM path, same as for the providers added in #5042.

We (DeepInfra) maintain the API and will maintain this integration. Follow-ups as separate PRs: DeepInfra embeddings provider (like the openrouter one in #7127) and DeepInfra in the CLI provider picker.

The code was written with AI assistance (Claude Code), so per CONTRIBUTING the llm-generated label applies - I can't set labels on this repo, please add it.

Register deepinfra in the OpenAI-compatible provider registry so
LLM(model="deepinfra/<org>/<model>") routes natively with DEEPINFRA_API_KEY
and no LiteLLM install. Model ids keep their org/model form,
DEEPINFRA_BASE_URL overrides the endpoint, and the docs accordion is added
in en, ar, ko and pt-BR.

deepinfra/ model strings previously routed through LiteLLM; is_litellm=True
keeps that path.

📝 Walkthrough

Walkthrough

Adds native OpenAI-compatible DeepInfra provider support. LLM routing recognizes DeepInfra model references, applies provider configuration, validates org/model identifiers, and documents setup in four locales.

Changes

DeepInfra provider integration

Layer / File(s) Summary
Provider routing and configuration
lib/crewai/src/crewai/llm.py, lib/crewai/src/crewai/llms/providers/openai_compatible/completion.py
DeepInfra model references route to OpenAICompatibleCompletion. The provider uses the default endpoint, requires DEEPINFRA_API_KEY, and supports DEEPINFRA_BASE_URL.
Configuration and routing validation
lib/crewai/tests/llms/openai_compatible/test_openai_compatible.py
Tests verify provider settings, missing-key errors, routing, endpoint overrides, explicit provider handling, and exact org/model validation.
Localized provider documentation
docs/edge/{en,ar,ko,pt-BR}/concepts/llms.mdx
Documentation describes DeepInfra setup, model identifiers, supported capabilities, model catalog links, and native OpenAI-client usage without a LiteLLM installation.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to 2cd9b

DeepInfra’s native provider path retains model identifiers and supports the documented credential and endpoint configuration. No merge-blocking risk was identified.

Require exactly one slash with both parts non-empty in the DeepInfra model id
check, as requested in review, and add the extra-segment and trailing-slash
cases to the pattern test. Add one sentence to the DeepInfra accordion in all
four locales saying the provider uses the native OpenAI client and needs no
LiteLLM install, so it cannot be read together with the LiteLLM note of the
neighbouring accordion.

On the "Linked Issues" warning: none of the four DeepInfra accordions mention LiteLLM - the uv add crewai[litellm] note that shows in the diff context belongs to the Nebius accordion right above ours. To make it impossible to misread, 2cd9bc9 adds one sentence at the top of the DeepInfra accordion in all four locales saying CrewAI talks to DeepInfra through its native OpenAI client and no LiteLLM install is needed.
