Deep research

[la-marc]

Hi,

Is there a built-in way of using the "deep research" models of openai?
I don't see them being listed as separate models and can't identify any option that would activate these capabilities.

(I tried searching Issues/Discussions for this but haven't found this being asked earlier. If it's a duplicate question, then I'm sorry.)

those models don't work with v1/chat/completions the endpoint used by gptel.
Anyway, you can set the models yourself and trying to call them to see the issue:

;; Add Deep Research models (o3-deep-research, o4-mini-deep-research)
(setq gptel--openai-models
      (append gptel--openai-models
              '((o3-deep-research
                 :description "OpenAI Deep Research flagship: for long-form, multi-step research, synthesis, and citation-backed output."
                 :capabilities (deep-research reasoning browsing tools)
                 :mime-types ("text/plain" "text/markdown")
                 :context-window 200000
                 :input-cost 10.00    ;; USD per 1M input tokens
                 :output-cost 40.00   ;; USD per 1M output tokens
                 :cutoff-date "2025-06")
                (o4-mini-deep-research
                 :description "OpenAI Deep Research (mini): lower-cost, latency-optimized Deep Research model."
                 :capabilities (deep-research reasoning browsing tools)
                 :mime-types ("text/plain" "text/markdown")
                 :context-window 200000
                 :input-cost 2.00     ;; USD per 1M input tokens
                 :output-cost 8.00    ;; USD per 1M output tokens
                 :cutoff-date "2025-06"))))

;; Make sure your gptel openai backend includes the models
(setq gptel--openai
      (gptel-make-openai
       "ChatGPT"
       :key 'gptel-api-key
       :stream t
       :models gptel--openai-models))
