Back in my AI research days, I personally loved focusing more on algorithmic/math improvements to get better models than throwing compute at a problem. In the long-term, I believe this is the main requirement to get us beyond the current level of intelligence... better…

Reinforcement learning can benefit from reproducible, shareable environments that agents can operate safely in. Lightning Studios allow you to create a fully isolated, sandbox environment for agents to operate in. Example: Here's a GRPO environment lightning.ai/lightning-purc…
Mind blown by thus Lightning piñata during our team offsite in Mexico ⚡️ ⚡️
Having your AI PhDs manage the AI infra.
It's crazy to stay locked into a single GPU cloud provider. You end up overpaying and can't hop around clouds on-demand in a second. Lightning's new GPU marketplace lets you jump around clouds on-demand with cloud agnostic storage. For example, you can save 50% on H100s if…
Funny thing is most people already work for an AI... it tells you what to do and you do it.
A big company reorg is basically killing off an (internal) failed startup and allocating the resources to a "new" startup with new leadership, people and mandates.

I love this upgrade. Lightning AI is my go-to cloud compute platform due to its user-friendliness (great UI, persistent environment, multi-GPU and multi-node support, etc), and now the prices are also really great. An A100 for $1.55/hour through Lambda Labs or an H100 for $2.70…

Woo... we just launched a DeepSeek-V3.1 endpoint on Lightning! - Input tokens: $0.32/million - Output tokens: $1.10/million - TTFT: 0.13s - Tok/s: 96.82 lightning.ai/models

China’s DeepSeek quietly released an open-source rival to GPT-5 — optimized for Chinese chips and priced to undercut OpenAI. What happens now? Thx to @_willfalcon & @bendee983 for weighing in fortune.com/2025/08/21/chi…
Building an agent/model, etc without a curated, benchmark dataset is the equivalent of vibe coding for AI. It's shocking how many people jump straight to building... but how will you measure progress or know if it's any good?
Wow, did not realize Gemini 1.5 pro has a 2M context window! 🤯🤯 lightning.ai/models
Attention students/professors - we're launching our new academic tier (50% off Pro) to support the next generation of researchers. Get the world's best GPUs (and now AI models by the token)... Lightning AI is used by top labs at Harvard, MIT, NYU, Stanford, Oxford, etc...…
Our cheapest model is GPT OSS 20B which includes 300 million free tokens per month on Lightning AI 🤯 What can you do with all these free tokens? 🤯
