feat(runtime-core,blocks): resolve the agent block provider instead of hardcoding OpenAI - #549
jamesbhobbs wants to merge 3 commits into
Conversation
…f hardcoding OpenAI Agent blocks could only run against OpenAI: `createOpenAI` was the only provider constructor, `'auto'` resolved to `gpt-5`, `providerOptions` was unconditionally `openai`, and the engine hard-failed without `OPENAI_API_KEY`. `OPENAI_BASE_URL` reached OpenAI-compatible endpoints but silently downgraded to Chat Completions, and could not reach Anthropic's native API at all. Add `agent-provider.ts`, which parses an optional `provider:model` prefix on `deepnote_agent_model` and builds the model plus its provider-specific options. Three providers: `openai` (unchanged default), `anthropic`, and `openai-compatible` for OpenRouter, Ollama, LiteLLM, vLLM, Together and Groq. A bare model name or `'auto'` still means `openai`, so existing `.deepnote` files are unaffected, and only a known provider id counts as a prefix, which leaves slash-separated aggregator ids intact. `AgentBlockContext.openAiToken` becomes `apiKey`; the old field is kept as a deprecated alias so `vscode-deepnote` keeps building against this package.

The openai-compatible key fallback to OPENAI_API_KEY does not work.
Execution reads only DEEPNOTE_AGENT_API_KEY for openai-compatible. The docs promise a fallback to OPENAI_API_KEY. Setups that set only OPENAI_API_KEY fail before the agent runs.

The branch was cut before #546/#547 raised the `undici` override to 6.28.1. The merge kept main's `undici@6.28.1` package entry alongside the `undici: 6.28.0` snapshot reference introduced with `@ai-sdk/provider-utils`, so `pnpm install --frozen-lockfile` failed with ERR_PNPM_LOCKFILE_MISSING_DEPENDENCY and took every CI job with it. Also document the agent providers in the runtime-core README, per the documentation check added in #526. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

@ai-sdk/anthropicand@ai-sdk/openai-compatibleare pinned to3.0.127and2.0.81, the newest releases still on@ai-sdk/provider@3.x. Theirlatesttags are on@ai-sdk/provider@4(LanguageModelV4), whichai@6.0.253rejects at the type level. Renovate will want to bump both — they can only move onceaiitself moves.Decision on the issue's open question
openai-compatiblegets its ownDEEPNOTE_AGENT_*variables, with theOPENAI_*ones as fallbacks. OverloadingOPENAI_BASE_URLreads badly onceopenaiis one of three providers, and the fallback keeps the migration free.Draft, because
vscode-deepnoteneeds a companion PR before this is useful to editor users. Its model picker is a hardcoded OpenAI list (src/notebooks/deepnote/agentCellStatusBarProvider.ts:28) and its key prompt is OpenAI-only (src/notebooks/deepnote/deepnoteSecretStore.ts:18). The deprecatedopenAiTokenalias means this PR does not break its build, but a Claude model is unreachable from the editor until that lands.buildSystemPromptre-sends the whole notebook context on every step of the tool loop — but placing cache breakpoints is its own change.

Note on the first CI run
The initial push failed every job with
ERR_PNPM_LOCKFILE_MISSING_DEPENDENCY: no entry for 'undici@6.28.0'. The branch was cut before #546/#547 raised theundicioverride to 6.28.1, so the merge kept main'sundici@6.28.1package entry next to theundici: 6.28.0snapshot reference that came in with@ai-sdk/provider-utils.
