Inkling 2 Small trails three rival labs on the independent tests so far
Independent testers have scored Inkling 2 Small on three tests; it sits behind Anthropic, Google DeepMind and OpenAI on each, and Epoch AI has not posted an overall index rank.

Thinking Machines Lab released Inkling 2 Small on Nov. 5, 2026, as a mixture-of-experts model with 594 billion total parameters and 17 billion active, taking text and image input1,2. The model is on the company's Tinker platform for inference and fine-tuning, with weights still closed at launch; Thinking Machines says it intends to publish them under an Apache 2.0 license after external safety testing1,3. Artificial Analysis lists Tinker pricing at $0.30 per million input tokens and $1.00 per million output tokens, with cached input at $0.03 per million2.
Independent testers have posted scores on three of the desk's usual tests; Epoch AI has not given Inkling 2 Small a rank on its overall index among the 44 models on the scoreboard4. On ARC-AGI-2, visual pattern puzzles that most people can solve by working out a new rule, the ARC Prize Foundation measured Inkling 2 Small at 81.7 percent4. That is behind Claude Fable 5.2 at 93.8 percent, Gemini 4 Carbon at 94.2 percent and GPT-6 Astra at 95 percent on the same test4.
On SciCode, which asks a model to write code for problems taken from real scientific research, Artificial Analysis measured Inkling 2 Small at 52.3 percent4. Claude Fable 5.2 scored 67.7 percent, Gemini 4 Carbon 64.2 percent and GPT-6 Astra 56.5 percent4. On APEX-Agents, long professional tasks of the kind done in banking, consulting and law, with one attempt each, Mercor measured Inkling 2 Small at 46.8 percent4. Claude Fable 5.2 scored 80.1 percent, Gemini 4 Carbon 84.2 percent and GPT-6 Astra 64.7 percent4.
The scoreboard has no independent GPQA Diamond, FrontierMath, SimpleQA Verified or CritPt figures for Inkling 2 Small, tests that Epoch AI or CritPt have run on the three rival models4. Epoch AI also has not published an Epoch Capabilities Index number for Inkling 2 Small; Claude Fable 5.2 is at 173.4, Gemini 4 Carbon at 169.8 and GPT-6 Astra at 169 on that combined score4.
Thinking Machines says Inkling 2 Small scored 31 on the Artificial Analysis Intelligence Index, up from 13 for Inkling Small, and that it is stronger than the lab's first generation on agentic coding, vision, knowledge work and reasoning1. Artificial Analysis, running its own index, reports the same 31 score, an 18-point rise over Inkling Small, about 4 times as many output tokens per index task, and about $1.18 per task versus $0.20 for the earlier model2. THE DECODER, citing those figures, also notes the planned Apache 2.0 weight release and that the model does not support audio3.
Thinking Machines says the model is less optimized for chat, can overuse slashes, and can overreact to mental-health queries1. What remains unknown on the desk scoreboard is an overall Epoch rank, prices in the scoreboard's own table, and independent scores on the science, math and factual tests already posted for the three rival labs4.
