This Startup Beat Gemini 3 on ARC-AGI — at Half the Cost

Poetiq is a new startup founded by former DeepMind researchers that recently achieved a major jump on the ARC-AGI benchmark by layering a recursive self-improvement system on top of Gemini 3. In this conversation at NeurIPS, YC's Francois Chaubaurd sat down with Poetiq co-founder Ian Fisher to find out how they're increasing performance using prompts and system design alone. They also explore recursive self-improvement, benchmarking progress toward AGI, and why automating prompt engineering may be one of the most powerful levers in AI today.

    Poetiq’s ARC-AGI 2 result: 54% on the private test set

    Francois introduces Ian Fisher at NeurIPS and tees up Poetiq’s headline announcement. Ian explains Poetiq’s stack running on top of Gemini 3 achieved 54% on the ARC-AGI 2 private test set, positioning it as a major jump over prior results.

    • Poetiq is a newly formed company (started in June), largely ex-DeepMind
    • Core announcement: 54% on ARC-AGI 2 private test set using Poetiq + Gemini 3
    • Framing the result as a step-change vs previous state of the art
  2. 0:49 – 1:16

    Quantifying the gain: better than Gemini 3 DeepThink at half the cost

    The discussion pins down what the improvement means relative to Gemini 3 baselines. Ian emphasizes the fairest comparison is against Gemini 3 DeepThink—Poetiq scores ~9–10 points higher while costing about half as much.

    • Gemini 3 baseline cited around low-30% range (approximate)
    • Gemini 3 DeepThink baseline cited at ~45%
    • Poetiq claims ~54%: ~9–10 points better than DeepThink
    • Cost advantage: Poetiq is about half the cost of DeepThink
  3. 1:16 – 1:49

    Ian Fisher’s background: YC founder → Google acquisition → ML research focus

    Ian summarizes his entrepreneurial and research journey that led to Poetiq. He describes founding a prior YC company acquired by Google, then switching into Google Research and refocusing once LLMs became the dominant wave.

    • Poetiq is Ian’s third company; second was YC-backed Affordable
    • Affordable was acquired by Google in 2015
    • Ian transitioned into Google Research for fundamental ML work
    • LLMs motivated a major research refocus that seeded Poetiq
  4. 1:49 – 2:37

    Recursive self-improvement (RSI): the “holy grail,” but must be done safely

    Ian outlines Poetiq’s core thesis: faster, cheaper recursive self-improvement where AI systems make themselves better. He acknowledges broad competition and highlights the importance—and debate—around safety and desirability.

    • RSI framed as a central prize in AI: systems that improve themselves
    • Poetiq’s approach is positioned as faster and cheaper than typical paths
    • Competitive landscape includes major labs and startups
    • Safety is emphasized as a key requirement for RSI work
  5. 2:37 – 3:41

    Why ARC (and ARC-AGI 2) became the proving ground—plus the Gemini 3 timing

    Francois asks about targeting ARC and the ‘hill-climbing’ experience as Gemini 3 arrived. Ian explains Poetiq was initially focused on ARC 1, with ARC-AGI 2 used more as a sanity check—until Gemini 3 produced a ‘holy cow’ jump.

    • Initial focus was ARC 1; ARC-AGI 2 seemed much harder
    • Poetiq tested across different API model providers
    • Gemini 3 release changed performance dynamics significantly
    • ARC 1 improved from ~89% (other models) to ~95% (Gemini 3)
    • Running on ARC-AGI 2 after Gemini 3 yielded an unexpected surge
  6. 3:41 – 4:01

    RSI loop mechanics without weight access: prompts + surrounding system + evals

    Ian explains that Poetiq improves performance by iterating on tasks with measurable evaluation, even without access to model weights. The action space is not fine-tuning—it's prompt and system optimization around black-box API models.

    • RSI loop uses other evaluable tasks to drive improvement
    • No access to weights: optimization focuses on prompts and system design
    • System-level scaffolding is part of the controllable action space
    • Improvement is driven by structured iteration and measurement
  7. 4:01 – 5:01

    Ensembles, self-refinement, and voting: system-level optimization beyond single prompting

    Ian describes the solver architecture: multiple independent ensemble members call the base model multiple times to refine answers, then a voting/combination strategy selects the final output. Francois contrasts this with earlier DSPy-style approaches and notes Poetiq seems to achieve materially better results.

    • Ensemble members perform independent multi-step refinement
    • Multiple calls to the underlying model per problem
    • A voting/aggregation scheme combines candidates into a final answer
    • Positioned as similar in spirit to DSPy, but with additional proprietary improvements
  8. 5:01 – 6:18

    Why Gemini 3 “changed everything”: coding + visual problem-solving capability

    Ian attributes much of the leap to Gemini 3’s strength at writing code for visual problem solving, which maps well onto ARC-style tasks. He also notes Anthropic’s Opus 4.5 appears comparable in quality but more expensive, and swapping base models can yield similar outcomes.

    • Gemini 3 is described as unusually strong at coding for visual reasoning
    • This capability is linked to better ARC solver performance
    • Opus 4.5 shows similar quality in their tests but at higher cost
    • Poetiq’s approach is model-agnostic enough to swap base providers
  9. 6:18 – 7:10

    What’s next: more high-impact benchmarks, staying small, and building a business

    Ian says Poetiq plans to pursue additional important benchmarks (not disclosed) while also engaging with real customers. He notes the team is only six people (with a seventh joining), aiming to pair research momentum with market impact.

    • Plans include tackling more ‘high-impact’ benchmarks (kept confidential)
    • Poetiq team size: six, with a seventh starting soon
    • Transitioning from purely research wins to customer conversations
    • Goal: solve real business problems while advancing RSI capabilities
  10. 7:10 – 8:39

    Is RSI a path to AGI? ‘A bump’ now, but potentially a route to AGI and beyond

    Francois challenges whether RSI is merely incremental (like a small regularization boost) or fundamentally transformative. Ian argues both: you always want the performance bump, and RSI is among the most exciting plausible paths to AGI—though not the only one.

    • RSI provides pragmatic performance gains worth pursuing
    • Poetiq leveraged ARC rules (multiple-solution setting) to be cheaper and better in this context
    • In single-response settings, system overhead can make Poetiq costlier or equal-cost
    • Ian views RSI as a credible path to AGI and beyond, but not exclusive
  11. 8:39 – 9:09

    When to stop hill-climbing: compute cost, budget constraints, and prioritizing customers

    Francois asks whether performance plateaued or was stopped intentionally. Ian says they stopped hill-climbing because ARC-AGI runs were expensive and they needed to conserve resources for customer work—implying more gains may have been possible with more spend.

    • Hill-climbing on ARC-AGI was expensive to run
    • They stopped due to budget and operational constraints, not necessarily a plateau
    • Tradeoff: pushing benchmarks further vs reserving compute for customers
    • Implicit claim: further improvements may be possible with more funding
  12. 9:09 – 11:23

    Automating prompt engineers and agent builders: from ‘hand-built car’ to ‘car factory’

    The conversation closes on product vision: automating the human loop in prompt/agent development. Ian contrasts earlier DeepMind-era manual system-building with Poetiq’s approach—building a ‘factory’ that automates the creation and improvement of these systems.

    • Customer-facing excitement alongside research roadmap
    • Prompting is often the main controllable lever when models improve but remain black-box
    • Poetiq aims to automate prompt engineering and agent construction end-to-end
    • Analogy: moving from hand-assembling a system to building a factory that produces systems
