Computational algorithms trained on data to recognise patterns, make predictions, and perform tasks, including neural networks for content generation, behaviour simulation, computer vision, and natural language processing; the core artefact produced by a machine learning training pipeline.

Current Landscape (2026)
- The dominant model class shifted from plain instruction-tuned LLMs to explicit reasoning (“thinking”) models: OpenAI shipped o3/o4-mini and then GPT-5 (August 2025), iterating to GPT-5.2 (December 2025) and GPT-5.4 (March 2026), while Google released Gemini 2.5 Pro (March 2025) and Gemini 3 Pro with Deep Think (November 2025), the first model to break 1500 Elo on LMArena.
- Anthropic’s Claude 4.5 family (Sonnet, Haiku, Opus, rolled out September–November 2025) pushed real-world coding state-of-the-art, with Sonnet reaching 77.2% on SWE-bench Verified, reflecting a broader pivot toward long-horizon agentic tool-calling as the headline capability rather than raw next-token quality.
- Open-weight models became genuinely frontier-competitive and disrupted pricing: DeepSeek V3 and R1 (January 2025) matched GPT-4o/o1-class performance at roughly a tenth of the cost, followed by Meta’s Llama 4 Scout and Maverick (April 2025, the firm’s first natively multimodal mixture-of-experts models) and Alibaba’s Qwen3-235B.
- Mixture-of-experts (MoE) architectures became the mainstream design for large models (Llama 4, DeepSeek V3 at 671B total / 37B active, Qwen3, gpt-oss), decoupling total parameter count from per-token inference cost and enabling very long context windows (Gemini 2.5’s 1M tokens; Llama 4 Scout advertised up to 10M).
- OpenAI re-entered the open-weight space with gpt-oss-120b and gpt-oss-20b under an Apache 2.0 licence (August 2025), its first openly downloadable models since GPT-2, signalling that even closed-first labs now treat open weights as strategically necessary.
- Regulation moved from drafting to enforcement: EU AI Act obligations for general-purpose AI models (defined at >10^23 FLOP, with “systemic risk” models above 10^25 FLOP facing red-teaming, incident reporting and evaluation duties) applied from 2 August 2025, and the AI Office’s enforcement powers plus broad applicability landed on 2 August 2026, backed by fines up to €35m or 7% of global turnover.
- Transparency and provenance became mandated: the AI Act’s Article 50 labelling rules apply from August 2026, with machine-readable watermarking of AI-generated content required from 2 December 2026, forcing model providers to bake output-marking into their systems.
- Open challenges as of 2026 centre on benchmark saturation and contamination (MMLU/GSM8K near-ceiling, driving harder evals like Humanity’s Last Exam and SWE-bench Verified), the compute/energy cost and reliability of test-time “thinking”, copyright and training-data disclosure obligations, and agentic safety as models run autonomous multi-hour tool-calling workflows.
