Meta released Llama 4 Scout and Llama 4 Maverick on April 5, 2026 — the first open-weight natively multimodal models built with a Mixture-of-Experts (MoE) architecture. Scout is a 17B active parameter model with 16 experts that fits on a single NVIDIA H100, with an industry-leading 10 million token context window. Maverick is also 17B active parameters but with 128 experts, delivering performance that benchmarks comparably to GPT-4o and DeepSeek v3 on reasoning and coding tasks. Both models process text, images, and video inputs, and are freely available for download on Hugging Face and llama.com. Llama 4 Scout was trained on 40 trillion tokens of data. The MoE architecture means the models punch well above their weight in active parameter count — Scout competes with models 5-10x its size on many benchmarks, while keeping inference costs low. This release closes the gap between open and proprietary models significantly. Organizations that previously needed to pay for GPT-4o or Claude for multimodal tasks can now run comparable capability locally or via any cloud provider. For the open-source AI ecosystem, Llama 4 is the biggest release of 2026 so far.

Mistral Medium 3.5 is a 128B dense model with a 256k context window, scoring 77.6% on SWE-Bench Verified and 91.4 on τ³-Telecom. It's released with open weights under a modified MIT license — one of the strongest coding-capable open-weight releases this year. Priced at $1.50/M input and $7.50/M output via API, it's positioned as a cost-competitive alternative to proprietary frontier models for agentic and software engineering tasks. Alongside the model, Mistral is launching Vibe — a remote coding agent system that runs sessions in the cloud. Developers can start a task from the CLI or Le Chat, "teleport" their local session to the cloud (preserving history and approval state), and let it run asynchronously while they work on something else. Sessions run in isolated sandboxes and can automatically open pull requests on GitHub when complete. This competes directly with Devin, GitHub Copilot Workspace, and similar async coding agents. The Le Chat Work Mode adds a general-purpose agentic layer on top: multi-step workflows across email, calendar, and messaging, research synthesis from internal and external sources, and inbox triage with drafted replies. All actions are transparent and require explicit approval before anything sensitive executes. The combination of open weights, competitive pricing, and production-ready remote agents makes this one of Mistral's most significant releases since Mixtral.
Reviewer scorecard
“A multimodal MoE model that fits on a single H100 and handles 10M context is insane for the price of free. Scout is the model I'll be running for 80% of production workloads going forward — the economics versus GPT-4o or Claude don't even compare. Deploy it now.”
“Open weights at 77.6% SWE-Bench with cloud-native async agents is a compelling combo. The 'teleport local session to cloud' UX for Vibe is genuinely clever — it solves the context-loss problem when shifting from local to remote execution.”
“I'll still reach for frontier proprietary models for the hardest reasoning tasks and production-critical applications where errors are costly. But I can't deny that Llama 4 Scout closes the gap more than I expected. The 10M context on Scout is genuinely unprecedented for open weights.”
“77.6% on SWE-Bench is strong but still behind Claude Sonnet and GPT-5.5 on the same benchmark. The Vibe agent is in 'public preview' which typically means rough edges. Wait for v1.0 before betting a production workflow on it.”
“Llama 4 will commoditize multimodal AI the same way Llama 2 commoditized text generation. The 10M context window in an open-weight model is a civilizational-level unlock for researchers, non-profits, and countries that can't afford to depend on US cloud providers for advanced AI.”
“Open-weight models with integrated remote agent infrastructure is the architecture that democratizes agentic AI. Any developer can self-host the weights and build their own agent backend — no vendor lock-in required.”
“An open-weight model that understands images and video means I can build custom creative pipelines without routing everything through proprietary APIs. For studios, agencies, and indie creators, Llama 4 fundamentally changes the cost structure of AI-assisted production.”
“The Le Chat Work Mode covering email, calendar, and research synthesis is exactly what knowledge workers need. Mistral's approval-first approach to sensitive actions is the right balance between automation and human oversight.”
