Google officially ships Nano Banana 2.1 (gemini-nano-banana-2.1) GA: 1K/2K images now half the price of Nano Banana 2, and human-eval Elo 1050 beats Nano Banana Pro
On 2026-10-06 Google officially launched Nano Banana 2.1 and marked it GA in the Gemini API changelog as gemini-nano-banana-2.1. It is based on Gemini 3.6 Flash and is rolling out across the Gemini app, AI Studio, Search AI Mode, Flow, Stitch, Google Ads and Gemini Enterprise Agent Platform. Image output is priced at $30 per 1M tokens (Nano Banana 2: $60), which works out to $0.0336 per 1K image and $0.0504 per 2K image, about half the old price. The model card's side-by-side human eval puts text-to-image Elo at 1050, ahead of Nano Banana 2 (990) and Nano Banana Pro (935). gemini-3.1-flash-image is now deprecated, with no shutdown date announced. This confirms the silent Flow rollout we reported earlier.

OpenAI launches GPT-6.1 Terra: fast, low-cost computer use at $1/$5 per million tokens, half the price of GPT-5.6 Terra and GPT-6.1 Sol
On Oct 26 OpenAI released GPT-6.1 Terra, an efficient model for visual reasoning, precise computer use and natural writing. It is rolling out today to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, and in the API as gpt-6.1-terra. Standard API pricing is $1 input, $0.05 cached input and $5 output per million tokens, which OpenAI says is 50% lower than GPT-5.6 Terra and GPT-6.1 Sol, with a 1,050,000-token context window. By OpenAI's figures it scores 15 points higher than GPT-5.6 Terra on Agents' Last Exam at medium effort for about a third of the cost, and solves 50.3% of Terminal-Bench 4.0 at max effort.

OpenAI unveils three AI-produced results: a claimed refutation of the Exponential Time Hypothesis, local smoothing in every dimension, and an existence proof for QCD
In an Oct 26 blog post, OpenAI said its internal models produced three new results: a proof of Sogge's local smoothing conjecture in every dimension (which implies the Kakeya and Stein restriction conjectures), a Lean-verified proof that the Exponential Time Hypothesis (ETH) is false, and a rigorous existence proof for four-dimensional QCD and related quantum field theories including pure Yang-Mills. The math and CS papers and Lean proofs are in the openai/math GitHub repo; the physics artifacts are being held back while an external group led by David Gross writes them up. All of this is OpenAI's own claim and still awaits independent verification.
