Planner reasoning

This is a Polymarket question about whether the next Gemini Pro model's debut HLE Accuracy on agi.safe.ai will be ≥50%. Key drivers are (a) what HLE score agi.safe.ai currently displays for Gemini 3 Pro and other frontier models (the site uses a specific no-tools/standardized config that runs lower than vendor-reported tool-augmented numbers), (b) the rate of HLE score improvement per model generation, and (c) whether a new Gemini Pro even appears on the site before Dec 31, 2026. I'll anchor on the market price and then research the leaderboard levels and release timing.

# Current state No Gemini model labeled "Pro" has yet posted an HLE Accuracy of 50%+ on agi.safe.ai's no-tools headline chart. The highest confirmed Gemini Pro figure is Gemini 3.1 Pro at 44.4% (no-tools) / ~51.4% (with tools, not the headline metric). The presumptive "next" qualifying model (Gemini 3.5 Pro) has been delayed repeatedly since its May 2026 I/O announcement and had not shipped as of mid-August 2026; Google has instead been shipping only Flash-tier updates and gesturing toward "Gemini 4." # Timeline of key events - 2025-03-25: Gemini 2.5 Pro ~21% HLE (baseline reference) — reported (code_execution synthesis). - 2025-11-18: Gemini 3 Pro launches, 37.5% HLE no-tools; Gemini 3 Deep Think 41% no-tools — confirmed (Google blog, AOL/Yahoo). - 2026-02-12: Gemini 3 Deep Think (non-Pro variant) reported at 48.4% no-tools, highest Google score to date — confirmed (remio.ai, ekhbary.com). - 2026-02 (approx): Gemini 3.1 Pro reported at 44.4% no-tools / 51.4% with-tools, beating GPT-5.2 (34.5%) but reportedly not beating Claude Opus 4.6 — reported (vertu.com, interestingengineering.com); NOT confirmed whether formally added to agi.safe.ai chart yet. - 2026-05-19: Gemini 3.5 Pro announced at I/O, GA targeted for June; Gemini 3.5 Flash ships instead at 40.2% HLE (regression) — confirmed (techtimes, aitoolsreview). - 2026-06→2026-07-17: Gemini 3.5 Pro GA slips repeatedly (June→July→July 17, then further) — confirmed (findskill.ai, mashable, moneycontrol). - 2026-07-21/22: Google ships three new Flash-tier Gemini models but still no 3.5 Pro; Bloomberg reports internal quality/hallucination issues, base model rebuilt — confirmed (techcrunch, pymnts, moneycontrol). - 2026-07-23: Pichai downplays delay, points to "Gemini 4" and near-monthly release cadence — confirmed (computerworld, moneycontrol). - 2026-08-05: Demis Hassabis steps down as DeepMind CEO amid leadership shakeup — confirmed (fortune.com). - 2026-08-08/13: Gemini 3.5 Pro still in limited Vertex preview, unreleased; Gemini 3.7 Flash ships instead — confirmed (qcode.cc, samaa.tv). # Event Will the next Gemini "Pro"-labeled model added to agi.safe.ai's HLE chart display ≥50% HLE Accuracy? # Outcomes to forecast Yes / No # Kalshi market anchor No Kalshi-direct data was returned for this ticker. The only direct market pricing available is Polymarket for the identical ticker: **71.5% Yes**, down 18.5 pts over 7 days but up 21.5 pts over 30 days; range 50–91%; volume only ~$18.3k across 17 data points — thin, volatile market. Treat as a rough proxy for consensus, not a hard anchor. # Sub-question answers 1. Research could not directly confirm agi.safe.ai's live display for Gemini 3 Pro or the site's current max; press reports (aligned with Google's own no-tools figures) put Gemini 3 Pro at 37.5% and Gemini 3 Deep Think (non-Pro) at up to 48.4%, the apparent current ceiling. 2. Gen-over-gen jumps: Gemini 2.5→3 Pro: +16.5 pts (21%→37.5%); Gemini 3→3.1 Pro: +6.9 pts (37.5%→44.4%) — decelerating. Competitor moves: GPT-5→5.1/5.2 roughly flat/declining (26.5–34.5%); Claude Opus 4.5→4.6 reportedly reached ~53.1% with tools. 3. agi.safe.ai's headline appears to use the no-tools protocol, matching Google's self-reported 37.5% (Gemini 3 Pro) and 44.4% (Gemini 3.1 Pro); with-tools scores (e.g., 45.8%, 51.4%) are higher but not the resolving figure (claude_news). 4. Gemini 3.5 Pro was announced May 2026, delayed multiple times (June→July→ongoing), still unreleased as of Aug 13 2026; Google is emphasizing "Gemini 4" instead, with no firm date (gdelt_news, claude_news). agi.safe.ai's update lag after model release is not documented in research. 5. No frontier model has publicly exceeded 50% no-tools HLE per Google's own reporting; some with-tools scores (Claude Opus 4.6 ~53.1%, Gemini 3.1 Pro ~51.4%) exceed 50% but under a different (non-headline) protocol. Third-party leaderboards (Artificial Analysis 55.5%, BenchLM 64.7%) use divergent, tool-mixed methodologies not comparable to agi.safe.ai's headline metric. 6. Polymarket price 71.5% Yes (volatile, thin). No other Kalshi/Polymarket markets found specifically on HLE thresholds or Gemini release timing. # Key facts (high-confidence, factual) 1. [Google blog] Gemini 3 Pro: 37.5% no-tools HLE (Nov 2025). 2. [vertu.com] Gemini 3.1 Pro: 44.4% no-tools / 51.4% with tools (~Feb 2026). 3. [techcrunch/findskill/qcode.cc] Gemini 3.5 Pro repeatedly delayed, unreleased as of Aug 13, 2026. 4. [fortune.com] Hassabis stepped down as DeepMind CEO Aug 5, 2026 — organizational disruption risk. 5. [computerworld] Pichai now emphasizes "Gemini 4," suggesting 3.5 Pro may be skipped/deprioritized. # Cross-market signals - Kalshi related: no direct Gemini/HLE markets found; unrelated markets only. - Polymarket: 71.5% Yes on this exact ticker, high volatility, low volume/liquidity. - Sportsbook implied: N/A. # Analyst opinions and speculation - code_execution trend extrapolation (2 data points only) projects ~54–67% HLE for a mid-2026 Gemini Pro release, but flags this as likely overstated given benchmark saturation and deceleration already observed (16.5pt→6.9pt jump). - Analysts (aimlapi.com) expect 3.5 Pro to "surpass" prior HLE scores but no leaked/confirmed benchmark exists. # Directional lean per outcome - **Yes**: Historical trend of large jumps (2.5→3 Pro); Deep Think variant already at 48.4%, suggesting Pro tier could follow if given more compute/tools; market still pricing 71.5%. - **No**: Deceleration in gains (3.5x smaller jump 3→3.1 vs 2.5→3); highest confirmed Pro no-tools score is 44.4%, well short of 50%; repeated delays and reported quality/hallucination problems with 3.5 Pro; leadership turmoil (Hassabis exit); Google's own emphasis shifting to "Gemini 4" with no near-term date, risking no qualifying model by Dec 2026 close (resolves No by rule). # Gaps / unknowns - Unclear whether Gemini 3.1 Pro has already been formally added to agi.safe.ai's chart (if so, at 44.4%, this may have already resolved the market No) — critical unresolved fact. - No confirmed release date or benchmark for Gemini 3.5 Pro or Gemini 4. - agi.safe.ai's typical lag between model release and chart addition is undocumented. # Calibration anchors - Polymarket current price: 71.5% Yes (thin liquidity, high volatility — 50-91% range). - Precedent: largest historical single-gen HLE jump for Gemini Pro was +16.5 pts; most recent jump only +6.9 pts, well short of the ~13+ pt jump needed from 44.4%→50%+.

1. Both forecasters treat "clearing 50%" and "a qualifying model appearing before close" as largely independent, but the brief's critical unresolved fact—whether Gemini 3.1 Pro (44.4%) has already been formally added to agi.safe.ai's chart—could mechanically resolve the market No regardless of any future model's score; neither forecast assigns explicit probability to this "already resolved/frozen" scenario, which should sharply cap Yes if true. 2. Forecast 1's "only ~5.6 pts needed" framing cherry-picks the smallest possible gap (from 44.4%) while ignoring that the relevant comparison model is unknown/unreleased (Gemini 3.5 Pro or "Gemini 4"), and that the brief explicitly flags decelerating gains (16.5→6.9 pts) as evidence the next jump is more likely to fall in the 45-49% band than clear 50%; an 80% conditional-on-release probability of clearing 50% seems too high given this trend and given reported "quality/hallucination issues" requiring a rebuilt base model. 3. Neither forecast adequately weights the "Gemini 4 instead of 3.5 Pro" branch: if Google skips a Pro-labeled release entirely before Dec 31, 2026 and only ships "Gemini 4" (unclear if it would even carry the "Pro" label), this is a distinct No pathway from "delayed release" that could combine with timeline risk to push total No probability well above what's stated—Pichai's own comments and Hassabis's departure suggest organizational uncertainty about naming/roadmap, not just timing. 4. Both forecasters lean on the Deep Think 48.4% figure as evidence Pro could follow, but Deep Think is explicitly a higher-compute, non-Pro variant (likely using extended reasoning/search), so its score may not transfer to a standard Pro-tier model with different latency/cost constraints—this analogy is weaker than both treat it. 5. Neither critique flags that the Polymarket 71.5% anchor is "down 18.5 pts over 7 days"—a large, fresh negative move—which may reflect market participants pricing in the Aug 2026 delay/Hassabis news more than the forecasts credit; Forecast 1 "discounts modestly" and Forecast 2 "discounts materially" but neither explains why they land above/near a market that just moved sharply against Yes. 6. Both forecasts converge in the 55-67% Yes range without seriously modeling the compounding of three independent risks (chart-timing/frozen-at-44.4% risk, no-Pro-release-by-close risk, and score-shortfall-even-if-released risk), any one of which alone could push No above 50%, suggesting both are overconfident on Yes relative to the brief's cumulative risk factors.

53% (43% confidence)

Yes: 53% No: 47%

Yes requires three things to all go right: (1) the chart isn't effectively frozen by Gemini 3.1 Pro being added at 44.4% (which would mechanically resolve No), (2) a Pro-labeled model actually debuts and is charted before Dec 31, 2026 despite 3.5 Pro's repeated slips, reported hallucination/quality rebuilds, Hassabis's departure, and a roadmap pivot toward 'Gemini 4' of uncertain naming, and (3) that model clears 50% on the no-tools headline protocol, where no frontier model has yet publicly exceeded 50% and Gemini Pro's most recent gen-over-gen gain was only +6.9 pts. Multiplying roughly 0.85-0.9 x 0.75-0.8 x 0.55-0.65 lands near 0.40-0.45, meaningfully below both submitted forecasts and far below the thin Polymarket 71.5% print — which itself just fell 18.5 pts in a week as the delay/leadership news landed, suggesting the tape is trending toward my view. I temper the fully compounded bearish case because Deep Think's 48.4% shows Google's stack is close, a full-generation Pro release would plausibly clear 50%, and labs actively optimize for HLE headlines, so I settle just above even at 0.53 Yes.
