Streaming works on both routes. + +Three things in that file matter on OCI: + +- **Set `prompt`.** The packaged capability card describes a coding agent with tools and a + harness. Against it, every judge tried here rated a mathematics proof as "supported" and + all traffic went to the efficient model. The card above describes the deployed efficient + model instead. +- **Give each target a distinct model id.** `v0.3.0` keeps one target per client and model id, + so a judge that reuses the efficient model's id is dropped with a warning. Point both roles + at one target instead, or use different models. +- **Choose the judge for schema-valid verdicts.** Llama 4 Maverick returned a valid verdict in + about half a second on every prompt tried. Llama 4 Scout and gpt-oss-120b sometimes returned + an inconsistent rule and boundary, which routes to the capable model as a fail-open. Gemini + 2.5 Flash-Lite returned `p_solve` as a string. Grok 4.7 was valid but took 13 to 65 seconds + per verdict. + +## OpenAI models on OCI + +The OpenAI `gpt-5.x` and `gpt-6.x` deployments reject `max_tokens` on Chat Completions +(`Use 'max_completion_tokens' instead`). Switchyard forwards the field a caller sends, so +they work as `efficient` or `capable` targets on an `openai_chat` client for callers that +omit `max_tokens`, but they cannot be the judge there in `v0.3.0`, because the judge call +always carries an output limit (`omit_body_fields` on `main` removes it). + +Use the Responses API for them instead. It takes `max_output_tokens` natively. On OCI it +needs one more statement on the key's policy, `manage generative-ai-response`; without it +the endpoint returns 404 `Authorization failed or requested resource not found`. Oracle's +Responses API documentation also says to create an OCI Generative AI project and pass its +OCID in the `OpenAI-Project` header; in the runs behind this recipe the OpenAI models answered +without one, while non-OpenAI models returned 400 asking for `OpenAI-Project` or +`opc-conversation-store-id`.

With the judge on +`openai.gpt-5.4-mini` and `max_completion_tokens` in place of `max_tokens`, the capability +classifier returned `p_solve` 0.99 for a rewrite and 0.17 for the proof, routing them to the +efficient and capable tiers respectively. + +## Notes + +- Streaming, JSON Schema structured output (Llama 4, Grok, OpenAI), tool calling and vision + input work on this endpoint. Cohere embeddings do not (`400 Unsupported OpenAI operation`). +- Tool calling has per-family rules that matter when an agent's turns are the answer requests. + Llama models require the first message to be a user message when `tools` are present (a + system prompt first returns `400 Tool calling for this Llama model requires the first message + to be a user message`); the judge is unaffected because its request is a single user message. + Gemini models reject a `tool` message whose `content` is a plain string (`400 Invalid value at + 'function_response.response' (google.protobuf.Struct)`); send tool results as JSON objects. + Cohere command models return `400 Unsupported OpenAI operation` for `tools`. The OpenAI + models, `openai.gpt-oss-120b` and `xai.grok-4.7` accept a system message first, `tools`, and + string tool results, so an agent that routes its own turns should pick its efficient target + from those; `meta.llama-4-scout-17b-16e-instruct` fits text tasks that carry no tools. +- Grok targets report about 1,250 prompt tokens on a one-line request and include + `cost_in_usd_ticks` in `usage`; budget accordingly. +- Set `timeout_ms` on the judge's client so an unresponsive judge returns `504` instead of + waiting. +- Cost estimates use OCI's own model IDs, which are not in the packaged price table; supply an + override with OCI's list prices if you want cost figures. +- Dedicated AI Cluster endpoints and signed OCI principals use the native OCI API, which needs + request signing. Put a gateway that signs for OCI in front and point the client at it. +- Other realms use their realm domain in place of `oraclecloud.com`. diff --git a/mkdocs.yml b/mkdocs.yml index 61e1bd7429..72b5d621aa 100644 --- a/mkdocs.yml +++ b/mkdocs.yml @@ -28,6 +28,8 @@ nav: - Embed in Your Gateway or Harness: reference/host_integration.md - Gateways: - NeMo Relay: integrations/nemo_relay.md + - Model Providers: + - OCI Generative AI: recipes/oci_generative_ai.md - Routing: - Algorithms: - Overview: routing_algorithms/overview.md
