Meta’s reply to DeepSeek is right here: Llama 4 launches with lengthy context Scout and Maverick fashions, and 2T parameter Behemoth on the way in which!

The complete AI panorama shifted again in January 2025 after a then little-known Chinese language AI startup DeepSeek (a subsidiary of the Hong Kong-based quantitative evaluation agency Excessive-Flyer Capital Administration) launched its powerful open source language reasoning model DeepSeek R1 publicly to the world, besting the efficiency of U.S. tech giants equivalent to Meta.

As DeepSeek utilization unfold quickly amongst researchers and enterprises, Meta was reportedly sent into panic mode upon studying that this new R1 mannequin had been educated for a fraction of the price of many different main fashions, as little as several million dollars — what it pays a few of its personal AI workforce leaders — but nonetheless achieved prime efficiency within the open supply class.

Meta’s complete generative AI technique as much as that time had been predicated on releasing best-in-class open supply fashions underneath its model identify “Llama” for researchers and firms to construct upon freely (a minimum of, if they’d fewer than 700 million month-to-month customers, at which level they’re imagined to contact Meta for particular paid licensing phrases).

But DeepSeek R1’s astonishingly good efficiency on a much smaller price range had allegedly shaken the corporate management and compelled some sort of reckoning, with the final model of Llama, 3.3, having been launched only a month prior in December 2024 but already wanting outdated.

Now we all know the fruits of that reckoning: at the moment, Meta founder and CEO Mark Zuckerberg took to his Instagram account to announce a new Llama 4 series of models, with two of them — the 400-billion parameter Llama 4 Maverick and 109-billion parameter Llama 4 Scout — accessible at the moment for builders to obtain and start utilizing or fine-tuning now on llama.com and AI code sharing neighborhood Hugging Face.

A large 2-trillion parameter Llama 4 Behemoth can also be being previewed at the moment, though Meta’s blog post on the releases stated it was nonetheless being educated, and gave no indication of when it could be launched. (Recall parameters check with the settings that govern the mannequin’s habits and that typically extra imply a extra highly effective and complicated throughout mannequin.)

One headline characteristic of those fashions is that they’re all multimodal — educated on, and subsequently, able to receiving and producing textual content, video, and imagery (audio was not talked about).

One other is that they’ve extremely lengthy context home windows — 1 million tokens for Llama 4 Maverick and 10 million for Llama 4 Scout — which is equal to about 1,500 and 15,000 pages of textual content, respectively, all of which the mannequin can deal with in a single enter/output interplay. Meaning a consumer may theoretically add or paste as much as 7,500 pages-worth-of textual content and obtain that a lot in return from Llama 4 Scout, which might be useful for information-dense fields equivalent to drugs, science, engineering, arithmetic, literature and so forth.

Right here’s what else we’ve realized about this launch to date:

All-in on mixture-of-experts

All three fashions use the “mixture-of-experts (MoE)” structure strategy popularized in earlier model releases from OpenAI and Mistral, which basically combines a number of smaller fashions specialised (“specialists”) in numerous duties, topics and media codecs right into a unified complete, bigger mannequin. Every Llama 4 launch is alleged to be subsequently a combination of 128 completely different specialists, and extra environment friendly to run as a result of solely the skilled wanted for a selected process, plus a “shared” skilled, handles every token, as a substitute of the complete mannequin having to run for each.

Because the Llama 4 weblog put up notes:

Because of this, whereas all parameters are saved in reminiscence, solely a subset of the entire parameters are activated whereas serving these fashions. This improves inference effectivity by reducing mannequin serving prices and latency—Llama 4 Maverick could be run on a single [Nvidia] H100 DGX host for simple deployment, or with distributed inference for max effectivity.

Each Scout and Maverick can be found to the general public for self-hosting, whereas no hosted API or pricing tiers have been introduced for official Meta infrastructure. As an alternative, Meta focuses on distribution via open obtain and integration with Meta AI in WhatsApp, Messenger, Instagram, and internet.

Meta estimates the inference value for Llama 4 Maverick at $0.19 to $0.49 per 1 million tokens (utilizing a 3:1 mix of enter and output). This makes it considerably cheaper than proprietary fashions like GPT-4o, which is estimated to value $4.38 per million tokens, primarily based on neighborhood benchmarks.

Certainly, shortly after this put up was revealed, I obtained phrase that cloud AI inference provider Groq has enabled Llama 4 Scout and Maverick on the following costs:

• Llama 4 Scout: $0.11 / M enter tokens and $0.34 / M output tokens, at a blended fee of $0.13
• Llama 4 Maverick: $0.50 / M enter tokens and $0.77 / M output tokens, at a blended fee of $0.53

All three Llama 4 fashions—particularly Maverick and Behemoth—are explicitly designed for reasoning, coding, and step-by-step downside fixing — although they don’t seem to exhibit the chains-of-thought of devoted reasoning fashions such because the OpenAI “o” sequence, nor DeepSeek R1.

As an alternative, they appear designed to compete extra straight with “classical,” non-reasoning LLMs and multimodal fashions equivalent to OpenAI’s GPT-4o and DeepSeek’s V3 — excluding Llama 4 Behemoth, which does seem to threaten DeepSeek R1 (extra on this beneath!)

As well as, for Llama 4, Meta constructed customized post-training pipelines targeted on enhancing reasoning, equivalent to:

• Eradicating over 50% of “simple” prompts throughout supervised fine-tuning.
• Adopting a steady reinforcement studying loop with progressively more durable prompts.
• Utilizing move@okay analysis and curriculum sampling to strengthen efficiency in math, logic, and coding.
• Implementing MetaP, a brand new approach that lets engineers tune hyperparameters (like per-layer studying charges) on fashions and apply them to different mannequin sizes and sorts of tokens whereas preserving the meant mannequin habits.

MetaP is of explicit curiosity because it might be used going ahead to set hyperparameters on on mannequin after which get many different sorts of fashions out of it, growing coaching effectivity.

As my VentureBeat colleague and LLM skilled Ben Dickson opined ont the brand new MetaP approach: “This could save lots of money and time. It implies that they run experiments on the smaller fashions as a substitute of doing them on the large-scale ones.”

That is particularly important when coaching fashions as massive as Behemoth, which makes use of 32K GPUs and FP8 precision, reaching 390 TFLOPs/GPU over greater than 30 trillion tokens—greater than double the Llama 3 coaching knowledge.

In different phrases: the researchers can inform the mannequin broadly how they need it to behave, and apply this to bigger and smaller model of the mannequin, and throughout completely different types of media.

A strong – however not but the most highly effective — mannequin household

In his announcement video on Instagram (a Meta subsidiary, naturally), Meta CEO Mark Zuckerberg stated that the corporate’s “aim is to construct the world’s main AI, open supply it, and make it universally accessible so that everybody on this planet advantages…I’ve stated for some time that I feel open supply AI goes to change into the main fashions, and with Llama 4, that’s beginning to occur.”

It’s a clearly rigorously worded assertion, as is Meta’s weblog put up calling Llama 4 Scout, “one of the best multimodal mannequin on this planet in its class and is extra highly effective than all earlier technology Llama fashions,” (emphasis added by me).

In different phrases, these are very highly effective fashions, close to the highest of the heap in comparison with others of their parameter-size class, however not essentially setting new efficiency data. Nonetheless, Meta was eager to trumpet the fashions its new Llama 4 household beats, amongst them:

Llama 4 Behemoth

• Outperforms GPT-4.5, Gemini 2.0 Professional, and Claude Sonnet 3.7 on:
  • MATH-500 (95.0)
  • GPQA Diamond (73.7)
  • MMLU Professional (82.2)

Llama 4 Maverick

• Beats GPT-4o and Gemini 2.0 Flash on most multimodal reasoning benchmarks:
  • ChartQA, DocVQA, MathVista, MMMU
• Aggressive with DeepSeek v3.1 (45.8B params) whereas utilizing lower than half the energetic parameters (17B)
• Benchmark scores:
  • ChartQA: 90.0 (vs. GPT-4o’s 85.7)
  • DocVQA: 94.4 (vs. 92.8)
  • MMLU Professional: 80.5
• Price-effective: $0.19–$0.49 per 1M tokens

Llama 4 Scout

• Matches or outperforms fashions like Mistral 3.1, Gemini 2.0 Flash-Lite, and Gemma 3 on:
  • DocVQA: 94.4
  • MMLU Professional: 74.3
  • MathVista: 70.7
• Unmatched 10M token context size—preferrred for lengthy paperwork, codebases, or multi-turn evaluation
• Designed for environment friendly deployment on a single H100 GPU

However in any case that, how does Llama 4 stack as much as DeepSeek?

However in fact, there are a complete different class of reasoning-heavy fashions equivalent to DeepSeek R1, OpenAI’s “o” sequence (like GPT-4o), Gemini 2.0, and Claude Sonnet.

Utilizing the highest-parameter mannequin benchmarked—Llama 4 Behemoth—and evaluating it to the intial DeepSeek R1 release chart for R1-32B and OpenAI o1 fashions, right here’s how Llama 4 Behemoth stacks up:

What can we conclude?

• MATH-500: Llama 4 Behemoth is barely behind DeepSeek R1 and OpenAI o1.
• GPQA Diamond: Behemoth is forward of DeepSeek R1, however behind OpenAI o1.
• MMLU: Behemoth trails each, however nonetheless outperforms Gemini 2.0 Professional and GPT-4.5.

Takeaway: Whereas DeepSeek R1 and OpenAI o1 edge out Behemoth on a pair metrics, Llama 4 Behemoth stays extremely aggressive and performs at or close to the highest of the reasoning leaderboard in its class.

Security and fewer political ‘bias’

Meta additionally emphasised mannequin alignment and security by introducing instruments like Llama Guard, Immediate Guard, and CyberSecEval to assist builders detect unsafe enter/output or adversarial prompts, and implementing Generative Offensive Agent Testing (GOAT) for automated red-teaming.

The corporate additionally claims Llama 4 reveals substantial enchancment on “political bias” and says “particularly, [leading LLMs] traditionally have leaned left in the case of debated political and social subjects,” that that Llama 4 does higher at courting the suitable wing…in step with Zuckerberg’s embrace of Republican U.S. president Donald J. Trump and his social gathering following the 2024 election.

The place Llama 4 stands to date

Meta’s Llama 4 fashions convey collectively effectivity, openness, and high-end efficiency throughout multimodal and reasoning duties.

With Scout and Maverick now publicly accessible and Behemoth previewed as a state-of-the-art instructor mannequin, the Llama ecosystem is positioned to supply a aggressive open different to top-tier proprietary fashions from OpenAI, Anthropic, DeepSeek, and Google.

Whether or not you’re constructing enterprise-scale assistants, AI analysis pipelines, or long-context analytical instruments, Llama 4 gives versatile, high-performance choices with a transparent orientation towards reasoning-first design.
