Dates beside benchmark scores refer to the linked source’s publication or capture date unless that source explicitly states when it measured the result. A shared URL alone does not establish comparable runs; unverified setups are marked. Prices are USD per million tokens at standard rates, excluding batch and caching discounts. Values we could not confirm from the provider are shown as “Not verified” rather than estimated.

    Composite index blending reasoning, knowledge, and coding evals into one 0–100 score.

    Comparable with caveatOnly same-version scores are comparable. v4.3.2 was rebaselined (the top score fell from 66 on v4.1.1 to ~58), so v4.1.1 figures must not be compared with v4.3.2 figures — check the cited source and its date.

Pricing tiers

Amazon Nova 2 Pro: Bedrock Global Standard $1.25/$10 per MTok; single-region $1.375/$11. Global Flex/Batch $0.625/$5; Global Priority $2.1875/$17.50. These are native Nova 2.0 Pro meters in the September 30, 2026 offer file, not custom-model or training rates. No Pro cached-input meter is present in this snapshot. Price meters do not establish account access.

GPT-6.1 Sol: Standard $2/$10 per million tokens up to 272K input; cached input $0.10 and cache writes $2.50. Above 272K, the full request costs $4/$15 ($0.20 cached, $5 cache writes). Batch/Flex are half Standard; Fast is twice Standard. Regional/FedRAMP processing adds 10% where eligible; Fast is unavailable with EU data residency. No none/minimal reasoning. Use Responses for tools; Chat Completions has no tool calling.

BalancedRecord checked October 2, 2026

Amazon Nova 2 Pro

Amazon's closed Nova 2 Pro preview accepts text, images, video and speech and generates text; its launch announcement specifies a one-million-token context.

Best for

  • AWS-native workloads
  • Multimodal
  • Long-context

Watch out

Preview access was announced for Nova Forge customers through their AWS account team. Current account access, a stable API model ID and a hard output cap remain unverified. Launch documentation names low/medium/high thinking; the current detailed thinking guide covers Lite only, so do not transfer its request rules to Pro. The October 1 Artificial Analysis 14-point Pro row is an estimate and is withheld. Omission from a current model list does not prove retirement.

BalancedRecord checked October 1, 2026

GPT-6.1 Sol

OpenAI’s newer Sol model for coding, computer use and professional work, with the same base token price as GPT-6 Sol and lower cached-input pricing.

Best for

  • Agentic coding
  • Computer use
  • Professional work

Watch out

Compare quality on your own tasks. Reasoning starts at low; none and minimal are unsupported. Long prompts above 272K increase the rate for the whole request.

When the cheaper one wins

Both charge $10 per million output tokens at standard rates, so output price is not the split. Prefer the row whose “best for” line matches the job, then confirm the live vendor rate.

Evidence confidence: Medium

How strong and complete the evidence behind this comparison is — not a prediction of which model is better.

  • Pricing verified on both sides — Input and output rates are verified for both models.
  • 3/5 core specs verified on both sides — Not published for at least one side: max output, parameter count.
  • No directly aligned benchmark setup — No benchmark has matching cited sources, source dates, units, effort and recorded run details on both models.
  • Verified within the last 90 days — Older of the two catalog checks was 25 days ago.
  • Both models carry source citations — Each side has at least two catalog sources on record.
