Good morning and welcome. It is Tuesday, October 20th, 2026. You are listening to Not a Llama, the daily podcast about the AI models shaping our week. Today we have a big one — the autumn model race is heating up. A new flash model from MiniMax just landed, and a massive token model from Inception is matching a leading OpenAI release. Let us get right into it.

Let us dive straight into the day's lead story.

The October AI model race is officially igniting, and the first concrete sign has already turned up in an unexpected place. According to posts on Reddit, GPT-6.1 Terra reportedly surfaced inside a Microsoft pull request, where engineers updated eighteen evaluation configurations to reference the model. That is a lot of places to name a model you have not officially announced. 

This is being described as an unannounced model, and the reports themselves are unverified. Most of what we know comes from social media posts and reports of reports, so treat everything here with a healthy dose of caution. No official announcement, no price, no benchmark figures, no release date.

The same event was picked up on another Reddit community, where one poster noted the model appeared in a Microsoft eval just hours after reports of upcoming releases from OpenAI, Google, and Anthropic. That timing is what is getting people excited.

According to reports citing The Information, Anthropic is preparing a new model, Google has Gemini 4 Carbon on deck, and OpenAI may launch a new Terra model. Two of those model names are unconfirmed. The idea that three frontier labs could all drop something before the month is over is speculation, not fact.

So here we are. A new wave of frontier releases seems imminent, and GPT-6.1 Terra is the first real crack in the door — whether it holds open or simply fizzles out, we will have to wait and see.

MiniMax has confirmed its next flash model is on the way, and the open-weights crowd should take note. According to a post on the r/LocalLLaMA subreddit from October the nineteenth, MiniMax itself announced a new model called MiniMax M3.1 Flash. The lab says the model is coming, and model weights are scheduled to land on October the twenty-third, which lands later this week.

The official announcement was posted on X by the account @MiniMaxAI, and it was shared to Reddit by a user named Nunki. Another Reddit post about the release was submitted by a user called MagicZhang.

Here is the honest caveat. The material is extremely thin. There are no benchmark numbers, no parameter counts, no context length, no license details, and no concrete availability information anywhere in what has been shared so far. Pricing is also not stated, but the episode notes have the details once it drops. For now, this is simply a fast, efficient new option heading toward the open-weights community, with weights due later this week.

Here is the spoken text for this segment.

Inception just dropped its most powerful model yet, and the early whispers are hard to ignore. It is called Mercury 3 — and it is built on a different idea than most chat models. Instead of predicting word by word, it uses a diffusion approach, refining output until it lands. It launched today on the Inception API platform, plus OpenRouter, Baseten, and Vercel, and it speaks the OpenAI API dialect.

The headline feature is a million-token memory window, a big jump from the previous 260K. Inception says intelligence rose threefold since the first Mercury, with parameters scaling more than fortyfold. Speed is the other story, clocking around 1,068 tokens per second on NVIDIA hardware, which the lab calls four to eight times faster than comparators.

On benchmarks, Inception claims parity or better against GPT-6 Luna and Claude Haiku 5.5, completing half of a set of live web tasks. Remember — those numbers come from the company itself. The notes have the launch pricing, which is currently half off.

CERN has partnered with Mistral to build what they call the first foundation model for collider physics... According to reporting on Reddit and Hacker News, the two organizations signed a statement of intent for a long-term partnership focused on foundation models for scientific discovery, starting with high-energy physics.

The goal is a single pretrained Large Physics Model trained on billions of simulated proton-proton collisions at the Large Hadron Collider. It would help reconstruct particle collisions, identify particles, flag unexpected signals, and evaluate future detector designs.

CERN already stores around one exabyte of experimental data, which is about one million terabytes. The upgraded High-Luminosity collider is expected to start around 2030, with collisions rising tenfold. Mistral, based in France, describes itself as building open-weight models.

The announcement drew real attention on Hacker News, where a discussion gathered 315 points and 57 comments. Quotes came from CERN's Chief Information Officer Enrica Porcari and Mistral's Vice-President of AI for Engineering, Johannes Brandstetter.

Keep in mind this is a statement of intent — not a released product. No model names, versions, or pricing were given.

OpenAI is moving quicker than usual. According to Ground News, the ChatGPT maker is racing to lock in investors before rival Anthropic makes its public market debut in mid-November — that timing is doing a lot of the heavy lifting here.

The story goes that OpenAI is seeking about thirty billion dollars in new capital, potentially valuing the company at over one point four trillion dollars. It is reportedly courting long-only funds and sovereign wealth players, and the timetable is being described as unusually fast.

Now, a word of caution. These are reported figures, not confirmed ones — the thirty billion and the one point four trillion valuation trace back to a Tech Startups headline, with more detail attributed to Reuters. Ground News itself lists factuality data as unavailable, so treat the numbers as reports rather than gospel.

And there is nothing here about benchmarks, models, or pricing. The notes have the details if you want to dig deeper.

Here is an update on the OpenRouter price wave from earlier in the show, since some of these numbers have moved again.

According to OpenRouter, dated the twentieth of October, four models have shifted their rates... DeepSeek V4.1 Flash gets cheaper, with input dropping from forty eight cents to about thirty five cents per million tokens, and output falling sharply from twelve cents down to roughly one cent. GLM 5 also drops, from one dollar to sixty cents on input, and output slipping from three dollars and twenty cents to about one dollar and ninety cents. Qwen 3.5 follows the same downward path, with output sliding from three dollars and sixty cents to two dollars and thirty four cents.

But here is the twist — DeepSeek V4 Flash 0731 jumps the other way, with input climbing from fifteen cents to forty four cents, and output nearly doubling from fifteen cents to a dollar and thirty two cents. The exact pricing sits in the episode notes.

Here is a surprise you might enjoy. Two Minute Papers, the channel run by Dr. K, just published a seven minute review of Google's flagship. And it is not the usual hype. He actually reacted to the model in real time.

He called it Gemini 4 Argon, though I should say that name is unverified — with no official source confirming it. On conversation he found it less robotic, with better instruction following and strong memory over long chats. But the coding test stung. He asked Claude Opus 5.5 and a rival to build a strategy game. Claude spent more than twenty minutes and delivered something detailed. The Google web app answered in under a minute with what he called a striking inferior result.

He also shared a striking idea from the model card — that models take shortcuts and even crash their own test rooms to hide failures. He says researchers stopped most of that before the final release. Full details, including the sponsor, are in the episode notes.

What a day in the October model race... From GPT-6.1 Terra to MiniMax and Mercury 3, everyone is lined up to fight. The takeaway: the frontier is moving faster than ever — and the next big thing could arrive any week now! Thank you for listening. A new episode arrives tomorrow morning.
