# deep-research-pro-preview-12-2025 shutdown: what to change Compared on Nov 13, 2026. The page: https://specstream.ai/migrate/gemini-deep-research-pro-preview Google lists `deep-research-pro-preview-12-2025` under deprecated agents, with October 23, 2026 as its shutdown date. To stay on Gemini, set `agent` to `deep-research-preview-04-2026` or `deep-research-max-preview-04-2026` in `interactions.create`. Google estimates $1.00 to $7.00 a task there. SpecStream is the live web data engine for teams and agents. `POST /v1/research` takes the same question and returns a written report with the page behind each cited sentence, at $0.10, $0.30 or $1.00 a report.

Google's estimate: $1.00 to $3.00 a task, and $3.00 to $7.00 on Max, at preview rates that can change | ## What changes, and why teams move the job to SpecStream ### What Google ended, and what it left running Google announced the deprecation in its release notes of October 8, 2026 and gave one date: October 23, 2026. Its deprecations page now lists `deep-research-pro-preview-12-2025` under deprecated agents with that shutdown date and `deep-research-preview-04-2026` as the recommended replacement. The same page says a model that is shut down is completely turned off and its endpoint is no longer available. The two 04-2026 agents are still previews. Both were released on April 21, 2026, and Google lists no shutdown date for either. Google gave 15 days between the notice and the date for the 12-2025 agent, so plan for the same again. ### On Gemini, the fix is one parameter Google's migration note is one sentence: update the `agent` parameter in your `interactions.create` requests from `deep-research-pro-preview-12-2025` to `deep-research-preview-04-2026`, or to `deep-research-max-preview-04-2026`. Google describes the 04-2026 agent as designed for speed and efficiency, and the Max agent as maximum comprehensiveness. The new agents add collaborative planning, visualization, MCP servers and File Search. The output can now hold images, so code that expects text alone should read each content part by its type. Token limits are the same on both model pages. ### A SpecStream report has a price before it starts Google's figures are estimates. A typical Deep Research task uses about 80 searches, a Max task up to 160, and the agent decides how much to read. A SpecStream report costs $0.10 for `quick`, $0.30 for `standard` and $1.00 for `deep`. The reply to the `POST` shows the price as `price_usd`, the balance pays it once when the report is delivered, and a cancelled report costs nothing. See [pricing](https://specstream.ai/pricing?utm_source=alternatives&utm_campaign=migrate-gemini-deep-research-pro-preview). ### Each cited sentence comes with its passage `report.content` is the text with `[1]` markers. `report.citations` gives each cited sentence its page, the time it was read and the passage that supports it, and `report.sources` lists every page read in the run. Your reader checks a sentence against the passage without opening the whole page. The [research report docs](https://specstream.ai/docs/research?utm_source=alternatives&utm_campaign=migrate-gemini-deep-research-pro-preview) list every field. ### JSON when your code needs fields Google's guide says the Deep Research agent does not support structured outputs. On SpecStream, send `"output": {"type": "json", "schema": {...}}` with a JSON Schema and the report comes back in that shape. `length` sets a `short`, `standard` or `long` report, and `include_domains` and `exclude_domains` choose the sites. ### Search and page reading on the same key The SpecStream Search API scores 97.9 F-score on all 1,000 official SimpleQA Verified questions (978 correct), and 64.0 item F1 and 43.4 row F1 on all 200 official WideSearch tasks. The Extract API scores 0.908 F1 on WCXB. Scores and method are on the [benchmarks](https://specstream.ai/benchmarks?utm_source=alternatives&utm_campaign=migrate-gemini-deep-research-pro-preview) page. The [Search API](https://specstream.ai/search-api?utm_source=alternatives&utm_campaign=migrate-gemini-deep-research-pro-preview) costs $5 per 1,000 searches of up to 10 results, or $1 with `speed=fast`, and the [Extract API](https://specstream.ai/extract-api?utm_source=alternatives&utm_campaign=migrate-gemini-deep-research-pro-preview) costs $0.80 per 1,000 pages. ## Other deep research APIs ### Parallel Task API SpecStream writes a report for $0.10, $0.30 or $1.00, a price you see before it starts. Parallel prices each run by processor, from $5 per 1,000 runs on lite to $2,400 per 1,000 on ultra8x. The ultra processor costs $300 per 1,000, or 30¢ a run, and takes 5 to 25 minutes. A SpecStream standard report costs the same 30¢ and takes about four minutes. ### Tavily Research One request takes 4 to 110 credits on mini and 15 to 250 on pro, at $0.008 a credit pay as you go, so 3¢ to $2 a request. The charge lands between the minimum and the maximum. A SpecStream report has one price for its depth, shown as `price_usd` before the work starts. ### OpenAI deep research OpenAI shut down `o3-deep-research` on July 23, 2026, and its deprecations page names `gpt-5.6-sol` as the replacement. SpecStream takes the same research prompt as `input` and returns the report with its citations for $0.10 to $1.00. The [OpenAI deep research page](https://specstream.ai/openai-deep-research-api?utm_source=alternatives&utm_campaign=migrate-gemini-deep-research-pro-preview) has the details. ### Gemini Deep Research with SpecStream's search The 04-2026 agents take remote MCP servers as tools. Add SpecStream at `https://api.specstream.ai/mcp` with `search_web` and `read_pages`, and the agent searches and reads the live web through SpecStream at $5 per 1,000 searches of up to 10 results and $0.80 per 1,000 pages. The [Gemini Deep Research page](https://specstream.ai/gemini-deep-research-api?utm_source=alternatives&utm_campaign=migrate-gemini-deep-research-pro-preview) has the code. ## How to move a deep-research-pro-preview-12-2025 call 1. Find the agent string. Search your code, config files and environment variables for `deep-research-pro-preview-12-2025`. 2. To stay on Gemini, change the `agent` value. Nothing else in the request changes. Keep `background=True` and poll the interaction by its `id`. ``` import time from google import genai client = genai.Client() interaction = client.interactions.create( agent="deep-research-preview-04-2026", # was "deep-research-pro-preview-12-2025" input="Research the history of Google TPUs.", background=True, ) while (result := client.interactions.get(id=interaction.id)).status != "completed": time.sleep(10) print(result.steps[-1].content[0].text) ``` 3. To move the job to SpecStream, create a key under Agents & API in the workspace. New accounts get $10 of credit, no card. Send the prompt as `input`. The reply is `202` with the report's `id` and its `price_usd`. ``` curl -X POST https://api.specstream.ai/v1/research \ -H "Authorization: Bearer $SPECSTREAM_API_KEY" \ -H "Content-Type: application/json" \ -d '{"input": "Research the history of Google TPUs.", "depth": "standard"}' ``` 4. Read it until `status` is `completed`, as you polled the interaction. `report.content` is the text, `report.citations` the cited sentences and `report.sources` every page read. ``` curl https://api.specstream.ai/v1/research/REPORT_ID \ -H "Authorization: Bearer $SPECSTREAM_API_KEY" ``` 5. If you streamed progress from Gemini, follow `GET /v1/research/{id}/events` (server-sent events, `Last-Event-ID` resumes) or pass `"webhook": {"url": "https://..."}`. Send an `Idempotency-Key` header on the `POST` so a retry returns the same report and is charged once. An agent can run the same report over MCP at `https://api.specstream.ai/mcp`: `research_price` shows the price of each depth, `start_research` starts the report once the person who pays approves that price, and `get_research` reads it. The [MCP guide](https://specstream.ai/docs/mcp?utm_source=alternatives&utm_campaign=migrate-gemini-deep-research-pro-preview) has the setup for each client. ## Frequently asked questions ### When was deep-research-pro-preview-12-2025 shut down?
