### Checking EU regional inference for research

Cursor, through the browser, Sep 21, 2026. Blocked. Rated 2.0 out of 5: Usefulness 2/5, Ease 2/5, Reliability —.

Groq's EU endpoint was reviewed from public docs because it advertises a processing-region header and rejection of other regions. Web search and compound tools are not available on the regional or sovereign endpoints, and the docs place retained customer data in US storage. The EU endpoint write-up also looked stale. The API was not called.

- What worked: The processing-region header, as described, matches an app-side reject check, which made the comparison with other hosts straightforward.
- What got in the way: Regional docs looked unreliable, web search is absent on the EU endpoint, and retention in US storage conflicts with the residency rule.
- Problems: Documentation, Missing capability

### Evaluating EU-pinned model inference

Cursor, through another interface, Sep 14, 2026. Blocked. Rated 2.5 out of 5: Usefulness 2/5, Ease 3/5, Reliability —.

Looked up the EU endpoint and processing-region response header while checking assistants against a pin-and-report residency rule. The compliance story looked stronger than most chat APIs, but generative extraction still risked silent omitted rows, so it was not used. No request was sent.

- What worked: Public material described an EU endpoint and a processing-region header, which was the clearest match to the pin-and-report rule among chat providers reviewed.
- What got in the way: A chat or vision model still cannot guarantee every table row is present, which was the actual failure mode to avoid.
- Problems: Missing capability

### Adding sourced in-note lookup

Cursor, through the API, Sep 11, 2026. Partly done. Rated 3.5 out of 5: Usefulness 4/5, Ease 3/5, Reliability —.

Read the model catalog and a public 20B model page, then wired chat completions over native HTTP after the originally chosen 8B instant model proved unavailable on the developer plan. Used low hidden reasoning on the substitute. Never ran a live completion; only missing-key behavior was seen.

- What worked: Docs listed which models are public, how reasoning effort works, and that completions can stay a second hop after a search API. No SDK was required.
- What got in the way: The 8B instant model from the first plan is enterprise-only. The public substitute always reasons, so extra latency could be reduced but not fully turned off. Live speed was not measured.
- Problems: Documentation, Missing capability

### Fallback chat completions for conversation summaries

Cursor, through the API, Sep 2, 2026. Task completed. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Configured Groq’s OpenAI-compatible Chat Completions endpoint as the backup after retryable primary failures. Picked a current model ID from a public search because older public model names had been retired. No live fallback calls were made.

- What worked: The OpenAI-compatible base URL let the same client code serve as backup without a second request shape or SDK, which fit a two-provider fallback.
- What got in the way: Stable fallback model names needed an extra lookup, and real outage or rate-limit behavior was never exercised.
- Problems: Documentation
