Releasing the model weights and technical report of Kimi K3.
Kimi K3 is our most capable model: a 2.8T MoE model with native visual understanding and a 1M-token context window.
New model architecture: 2.5x the intelligence per unit of compute, not just more params.
Alongside Kimi K3, we're opening up more of the stack behind it — high-performance attention kernels, MoE communication library, and infrastructure for running agent environments at scale.

New in Claude Cowork: teach Claude a skill.
Record your screen while you do a task, talk through it as you go, and Claude turns it into a skill it can run again. Find it under Record a skill in the + menu of the Claude desktop app.
Available on Pro, Max, and Team plans.
I talk to engineers at other companies every day and hear the same thing: one person is 10x'ing their output with Claude but the rest of the org hasn't caught up.
Watching teams adopt AI, I keep seeing the same 4 steps.
I mapped them out here: Steps of AI Adoption https://t.co/kQnRAUMKpP
Beginning July 20, Claude Fable 5 will be included in all Max and Team Premium plans, at 50% of limits.
Pro and Team Standard users will continue to have access to Fable via usage credits, and will receive a one-time $100 credit.
Demand for Fable has been challenging to predict, which is why we rolled it out to subscription plans in stages, extending access several times as we secured additional capacity.
Opus 5 Leaks
- Opus 5 is targeting a launch by the end of this month.
- A "Honeycomb EAP" model appeared in Cursor for some users before disappearing, and it could be an early Opus 5 preview.
- Honeycomb EAP has a 1M context window, making - Opus 5 most likely (Haiku is expected to have 300K context).
- Hopefully, Opus 5 reaches Fable/Mythos-level capabilities.
Our internal assessment is that Grok 4.5 is roughly comparable to Opus 4.7, but much faster. The combination of capability, faster speed and lower cost is what makes it competitive.
We are closing the loop on real-world usefulness, not benchmarks. Hardcore engineers at Tesla & SpaceX find Grok 4.5 genuinely useful, which is what actually matters.
i just built a skill that lets Claude Code actually watch and analyze any video you throw at it
the biggest limitation with Claude has always been that it can't actually watch videos. it just looks at individual frames and tries to piece together what's happening. which means you miss all the pacing, the audio, the flow, everything that actually makes a video work.
this skill fixes that. it gives claude native video understanding so Claude is actually watching the full thing, not just guessing from screenshots.
drop in a competitor ad, a viral TikTok, a UGC video, a screen recording, whatever. Claude watches it and hands you back a full creative teardown. hook breakdown, target audience, angle, beat-by-beat structure, on-screen text with timestamps, dialogue, everything.
here's how it works:
> drop any video file into Claude Code
> the skill routes it through Gemini so it actually watches the video (not just frames)
> you get back a full structured breakdown of the hook, angle, pain points, CTA, and on-screen text
> it generates hook variations you can steal for your own creative
this is super useful for anyone who constantly needs videos broken down fast
i wrote a full breakdown showing how i built this and i'm giving away the skill for free.
RT + reply "VIDEO" and i'll send it over (must follow so i can dm)
Sonnet 5 is a substantial improvement over Sonnet 4.6 on reasoning, tool use, coding, and knowledge work.
Its performance is close to Opus 4.8, at lower prices.
Major cheat code for life: Assume good things are still ahead. You are not behind. You are not too late. You are not disqualified by your past. One new season can change the entire story. Keep showing up with belief. The best chapters are often written after the hardest ones.
