Grok's own recommendation (consulted 2026-06-11):
'xAI (Grok) | xAI official OpenAI-compatible (https://api.x.ai/v1) |
Fully compatible and clean. Supports Grok-2 + Grok-2-Vision. No
meaningful unique native surface lost by using the compatible
endpoint.'
This REVERSES the earlier 'xAI native' correction. The OpenAI-
compatible approach for Grok is the canonical full-featured path;
the implementation in Phase 3 (OpenAI SDK with base_url=https://api.x.ai/v1
+ send_openai_compatible helper) is correct as-is.
Updates to the spec:
1. §3.1.1: replaced the 'use xAI native' decision with the confirmed
per-vendor table. Qwen=Native, Grok=OpenAI-Compatible (per Grok's
own confirmation), MiniMax=OpenAI-Compatible, DeepSeek=OpenAI-
Compatible, Ollama=OpenAI-Compatible-in-v1 (native in v2),
Meta Llama API=Native (new 4th backend, follow-up), Gemini=Native
(follow-up), Anthropic=Native (follow-up). Also added Grok's
recommended v2 matrix field expansion: audio, video, grounding,
computer_use, local, reasoning/extended_thinking, web_search,
x_search, code_execution, file_search, mcp_support, structured_output.
2. §4.3: reverted from 'Grok via xAI (Native REST API)' back to
'Grok via xAI (OpenAI-Compatible) - confirmed 2026-06-11'. The
implementation does NOT need a native refactor; the OpenAI SDK
at https://api.x.ai/v1 is the canonical approach. Removed the
earlier 'caching: true' entry from the registry (since the
OpenAI-compat shim doesn't expose prompt_cache_key) and the
'no persistent client' state struct (back to the OpenAI SDK
pattern).
3. §13.1.B: renamed from 'Native Vendor APIs' to 'Llama Native APIs
(Ollama native + Meta Llama API)' and removed the Grok native
refactor item (Grok says OpenAI-compat is fine). Kept the Ollama
native + Meta Llama API items + matrix expansion. Clarified that
Grok tests do NOT need rewriting; only Llama tests get 2 more
(native Ollama, Meta Llama API).
Net effect: the Phase 3 work that just shipped (Grok+Llama Green
using OpenAI-compat shim) is CORRECT as-is. The implementation
matches Grok's actual recommendation. No code rollback needed.
