Gemini and Grok model updates

Bourd now supports three new models: Gemini 3.5 Flash and Gemini 3.1 Flash Lite under the Gemini Model Provider, and Grok 4.3 under Grok. Four earlier models are retired in the same update.

New models

Gemini

Gemini 3.5 Flash. The speed-optimized Gemini tier, succeeding Gemini 3 Flash Preview. A good fit for high-volume scheduled runs where latency and cost matter more than peak reasoning.
Gemini 3.1 Flash Lite. The stable release of the earlier Gemini 3.1 Flash Lite Preview. The lowest-cost Gemini tier, suited to broad, routine monitoring.

Grok

Grok 4.3. xAI’s latest Grok, building on Grok 4 with improved reasoning and response quality for brand monitoring queries.

Retired models

Gemini 2.5 Pro is retired. Use Gemini 3.1 Pro Preview for Pro-tier Gemini analysis.
Gemini 3 Flash Preview is retired. Use Gemini 3.5 Flash instead.
Gemini 3.1 Flash Lite Preview is retired. Use the stable Gemini 3.1 Flash Lite instead.
Grok 4 is retired. Use Grok 4.3 instead.

Retired models can no longer be selected on new prompt runs or schedules. Historical responses that used them stay in your reports and remain filterable.

How to use

Open the Prompts page and create or edit a prompt
Select the new model under the Gemini or Grok Model Provider
Run your prompt or save it for scheduled execution

Existing schedules

Schedules created before this update keep their current model selections. New models are not added automatically: to run a schedule against Gemini 3.5 Flash, Gemini 3.1 Flash Lite, or Grok 4.3, edit it and select the model under the Gemini or Grok Model Provider. A schedule that still includes a retired model keeps running it; to switch, edit the schedule and select a current model.

All three new models work with every existing feature, including schedules, follow-up conversations, and response analytics. Usage is billed at standard rates. Check your plan’s model pricing for details.
