Google DeepMind says Gemini 4 is in refinement and nearing release
In his first media interview as DeepMind leader, Koray Kavukcuoglu said Gemini 4 is in a refinement stage and that Google aims to release an early post-training output 'much earlier' than the end of 2026. The comments follow a leadership change at DeepMind and come after Google’s last flagship, Gemini 3 (Nov 2025); competitors OpenAI (GPT-6) and Anthropic (Mythos) have released newer models.

DECISION BRIEF
CONFIDENCE
WHAT CHANGED
Google DeepMind’s new leader Koray Kavukcuoglu says Gemini 4 is in a refinement / early post‑training stage and that the team intends to release an early post‑training output “much earlier” than the end of the year. This statement follows a leadership change at DeepMind and comes after competitors released newer flagship models.
WHY NOW
Kavukcuoglu’s public comments mark the first media appearance by DeepMind’s new leader and signal an explicit intent to accelerate a flagship model release after competitor flagship launches and an internal pause to prioritize faster, smaller Flash models.
WHO IS AFFECTED
Directly affected parties include Google/DeepMind engineering teams (development and safety testing), internal users cited (engineers using the model for the Antigravity coding tool), and external competitors (OpenAI, Anthropic) whose recent releases have been compared to Gemini 3.
CONFIRMED
• Koray Kavukcuoglu said Gemini 4 is in a refinement / early post‑training stage and that DeepMind intends to release an early post‑training output “much earlier” than the end of the year. • Kavukcuoglu made these remarks in his first media appearance as DeepMind leader. • DeepMind changed leadership: Demis Hassabis stepped down and Kavukcuoglu became head; Hassabis now chairs the unit / serves as Alphabet’s chief scientist. • Google’s last flagship before this was the Gemini 3 series (November 2025); competitors OpenAI (GPT‑6) and Anthropic (Mythos) have released newer models since then and were described as outperforming Gemini 3. • Google engineers are using the Gemini 4 model internally for the Antigravity coding tool and the company is conducting safeguards / safety testing. • Google previously prioritized shipping faster, smaller Flash models and did not roll out the announced Gemini 3.5 Pro.
UNCERTAIN
Missing or conflicting evidence: • Exact public release timing for Gemini 4 — Kavukcuoglu says “much earlier” than the end of the year but provides no date or schedule; no public release date or launch plan is provided. • Whether an "early post‑training output" will be broadly public or limited to internal/partner use is not specified (source 1133 notes internal use). • The specific capabilities and comparative performance of Gemini 4 versus GPT‑6 / Mythos are not documented in these excerpts; statements note competitors “outperform” Gemini 3 but do not quantify Gemini 4’s expected performance. • Status and timeline for safety testing and safeguards are mentioned but not detailed; one source says guards/testing are ongoing without specifics. • The fate of Gemini 3.5 Pro is unclear—announced, never rolled out, and reported to have missed deadlines, but official cancellation is not stated.
WHAT TO WATCH
Concrete observable signals to monitor: 1) Official DeepMind / Google blog posts or press releases announcing Gemini 4 milestones or release (public launch, availability of “early post‑training” snapshot). 2) Publication of technical paper, model card, or safety assessment documents for Gemini 4. 3) Public demos, API availability, or product integrations showing Gemini 4 in consumer or developer products. 4) Expanded internal or partner disclosures (e.g., releases about Antigravity or other internal tools using Gemini 4). 5) Statements from Google leadership (Kavukcuoglu, Pichai, Hassabis) clarifying timeline, scope, or safety readiness. 6) Evidence of TPU / hardware announcements tied to new model requirements, or sales/listings of Google TPUs citing Gemini 4 workloads. 7) Media or independent benchmark reports comparing Gemini 4 performance to GPT‑6 / Mythos. (Each of these signal types would be observable in official Google/DeepMind communications, product pages, technical papers, press coverage, or third‑party benchmarks.)
WHY IT MATTERS
A Gemini 4 release would be a major move in the AI model race and signals Google’s intent to regain parity with recent competitor flagship models.

2The new frontier AI model should arrive long before the end of 2026. Google is reportedly nearing the launch of its long awaited Gemini 4 model, after dawdling behind rival developers on flagship AI releases. Speaking with The Information during his first media appearance as the leader of Google’s DeepMind division, Koray Kavukcuoglu said that Gemini 4 is currently in its refinement stage, and that the company is a…
Koray Kavukcuoglu wants to release Gemini 4 well before the end of the year. He calls the AGI question, which his predecessor Demis Hassabis always focused on, "not the right conversation." Under pressure from OpenAI and Anthropic, Google's former research lab has become a Gemini factory. Kavukcuoglu made his first media appearance as head of Google Deepmind at The Information's AI Agenda Live Summit. He said Gemini…
