From 42a11d35cdf388ee58d4fc7c81dd628bca6c1f35 Mon Sep 17 00:00:00 2001 From: profit Date: Wed, 22 Apr 2026 02:57:42 -0500 Subject: [PATCH] Phase 39 (first slice): Ollama Cloud adapter on /v1/chat MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Second provider wired. /v1/chat now routes by optional `provider` field: default "ollama" hits local via sidecar, "ollama_cloud" (or "cloud") hits ollama.com/api/generate directly with Bearer auth. Key sourced at gateway startup from OLLAMA_CLOUD_KEY env, then /root/llm_team_config.json (providers.ollama_cloud.api_key), then OLLAMA_CLOUD_API_KEY env. Config source matches LLM Team convention. Shape-identical to scenario.ts::generateCloud — same endpoint, same body, same Bearer auth. Cloud path bypasses sidecar entirely (sidecar is local-only by design, mirrors TS agent.ts). Changes: - crates/gateway/src/v1/ollama_cloud.rs (new, 130 LOC) — reqwest client, resolve_cloud_key(), chat() adapter, CloudGenerateBody / CloudGenerateResponse wire shapes - crates/gateway/src/v1/ollama.rs — flatten_messages_public() re-export so sibling adapters reuse the shape collapse - crates/gateway/src/v1/mod.rs — provider field on ChatRequest, dispatch match in chat() handler, ollama_cloud_key on V1State - crates/gateway/src/main.rs — resolves cloud key at startup, logs which source provided it - crates/gateway/Cargo.toml — reqwest 0.12 with rustls-tls Verified end-to-end after restart: - provider=ollama → qwen3.5:latest local (~400ms, Phase 38 unchanged) - provider=ollama_cloud + model=gpt-oss:120b → real 225-word technical response in 5.4s, 313 tokens Tests: 9/9 green (7 from Phase 38 + 2 new for cloud body serialization and key resolver shape). Not in this slice: trait extraction (full Phase 39 scope adds ProviderAdapter trait + OpenRouter adapter + fallback chain logic). These land next with Phase 40 routing engine on top.
