The Chinese AI company Moonshot AI released its Kimi K3 model yesterday. I played with it a bit in the Kimi iOS app and, frankly, was underwhelmed. It was slow and disappointing. But this was hardly an extensive test. Itโs strictly my first impression. Iโm not doing coding. Iโm what model makers would call a knowledge worker.
This morning Gavin Baker posted on X about Kimi K3 calling it potentially an โimportant inflection point for AIโ:
Kimi K3 may be an important inflection point for AI. Potentially negative for Anthropic and OpenAI while being net positive for essentially every other company in the world. I mean that very literally. Although the real โSputnik momentโ would be an open-source frontier model that was also token efficient unlike Kimi K3 which is 50-70% more expensive to run than GPT 5.6 per Artificial Analysis.
Rationale:
A world where there are only 2-3 dominant frontier labs with 90% inference margins is net negative for every other layer while being awesome for those 2-3 labs. Those labs would become monopsonies for power, data centers, semiconductors and hyperscalers and would obviously vertically integrate over time into all those layers while also completely subsuming the application/software layers.
Anything that lowers margins and increases competition at the model layer is good for every other AI layer: power, semiconductors, hyperscalers, neoclouds and yes even software.
This is why Jensen is so supportive of open-source. An open-source model requires the exact same amount of compute to run as a closed frontier model of similar size and architecture. Kimi K3 is roughly the same price as GPT 5.6 Terra on a per token basis, which actually suggests that it is less computationally efficient as I am sure that GPT 5.6 is priced to a higher margin than K3. And given that K3 is a token wastrel, i.e. token inefficient, it is significantly more expensive per task than GPT 5.6 and Grok 4.5, which are much more token efficient. Cost per token and token efficiency (i.e. intelligence density per token) are the drivers of intelligence per unit of cost. The winning AI companies will be those that offer the most intelligence per $ over time.
Lower margin % at the model layer = more margin $ at every part of the infrastructure layer and is a godsend for software. This can happen either through open-source models like K3 at the frontier or having a vertically integrated model company like Meta, SpaceX or Google at the frontier. Both outcomes result in a lower margin % at the model layer as vertically integrated model companies donโt really care where the margin $ come from. This is why it was so painful for OpenAI and Anthropic when Google was right there with them from a model competitiveness perspective and why Grok 4.5 and Muse 1.1 were just as important as Kimi K3.
โจThe reason Kimi K3 is only potentially negative for Anthropic and OpenAI is 1) the @ericvishria point that the Claude and ChatGPT products and harnesses may be more important than their models today and 2) the hypothesis that they have much more advanced model checkpoints internally that are already being used for RSI. In the latter scenario, reaching RSI even a few months ahead of other labs might be enough to cement a permanent lead.Time will tell on both points. And likely fairly quickly.
Caveat would be that since Kimi K3 is not token efficient and thereby actually more expensive than ChatGPT 5.6, we may need to see a more token efficient open-source model at the frontier or see Grok 5/Composer 4/Muse 2 at multiple points on the Pareto frontier for this potential risk to Anthropic and OpenAI to play out. And I am sure they will both vertically integrate as quickly as possible while continuing the product/harness strength they have shown over the last 8 months.
I wanted to explore this further so I asked Grok to explain his post:
This is a tweet (X post) from Gavin Baker (@GavinSBaker), Managing Partner and CIO of Atreides Management, posted on July 17, 2026.
It analyzes the recent launch of Kimi K3 (by Chinese AI company Moonshot AI) as a potentially significant shift in the AI industry. Baker argues it could hurt the high-margin dominance of closed U.S. frontier labs like OpenAI and Anthropic while benefiting nearly everyone else in the broader AI ecosystem (infrastructure, chips, data centers, power, hyperscalers, and software).
Quick Context on Kimi K3
Kimi K3 is Moonshot AIโs new flagship model (launched ~July 16, 2026). Key specs include:
- ~2.8 trillion parameter Mixture-of-Experts (MoE) architecture.
- Massive 1 million token context window.
- Native vision capabilities.
- Strong early performance in coding, agentic tasks, and long-context reasoning (competitive with or close to top closed models like GPT-5.6 variants or Claude models in certain benchmarks).
- Pricing: $3 input / $15 output per million tokens (with caching discounts).
- Important: Full weights are scheduled for open release (modified MIT license) around July 27, 2026 โ making it one of the first truly open frontier-scale models.
It represents a step up from prior Kimi models and adds meaningful competition from a non-U.S. lab.1
The Two Images in the Tweet
These are screenshots from Artificial Analysis (an independent benchmarking site):
- Bar chart โ โCost per Intelligence Index Taskโ (lower is better). It breaks down costs by token type (input, output, reasoning, cache, etc.) and shows Kimi K3 as relatively expensive compared to some GPT-5.6 variants.
- Scatter plot โ Intelligence Index (y-axis) vs. Cost per task (x-axis, log scale). It positions models in quadrants, with the โmost attractiveโ area being high intelligence at low cost. Kimi K3 appears competitive on intelligence but not the cheapest.
These visuals support Bakerโs point that while Kimi K3 reaches frontier-level intelligence, it is not the most token-efficient, making its effective cost per useful output higher than more efficient models.
Bakerโs Core Argument (Broken Down)
Bakerโs thesis is economic and structural, not just technical:
- A world with only 2โ3 dominant closed frontier labs (with ~90% inference margins) is bad for almost everyone else.
Those labs would act as monopsonies (dominant buyers) for power, chips, data centers, and compute. They would vertically integrate upward (into infrastructure) and downward (into apps/software), capturing most of the value. Competition at the model layer prevents this concentration. - Anything that increases competition or lowers margins at the model layer is broadly positive.
It redistributes economic value to the rest of the stack: more demand for GPUs/chips (inference especially), power, data centers, hyperscalers/neoclouds, and software (because cheaper/better AI drives wider adoption). - Token efficiency matters more than raw price per token.
Baker notes Kimi K3 is roughly the same per-token price as GPT-5.6 but 50-70% more expensive overall according to Artificial Analysis. It is a โtoken wastrelโ โ it uses more tokens to achieve similar results (lower โintelligence density per tokenโ).
โ True winners deliver the most intelligence per dollar. Cost-per-token + efficiency together determine real value. - Why NVIDIAโs Jensen Huang loves open-source models.
Open models still require massive compute to run at scale (same as closed ones). More models + wider adoption = more inference demand = more GPUs sold. A few ultra-high-margin closed labs would concentrate spend and reduce overall volume. - Vertical integration changes the game.
Companies like Google, Meta, or xAI/SpaceX that have both strong models and their own infrastructure donโt obsess over model-layer margins โ they capture value elsewhere. This is why more competition (open or vertically integrated) hurts pure-play high-margin model companies like OpenAI/Anthropic.
Why Itโs Only โPotentiallyโ Negative for OpenAI and Anthropic
Baker is careful:
- Their products, user interfaces, and โharnessesโ (the surrounding tools/ecosystems) may matter more than raw model performance right now.
- They likely have more advanced internal models/checkpoints (possibly already used for recursive self-improvement/RSI).
- Kimi K3โs token inefficiency softens the blow for now. A more efficient open-source frontier model (or stronger showings from Grok, etc.) would be more threatening.
- OpenAI and Anthropic are already moving to vertically integrate.
Overall Takeaway from the Post
Baker sees Kimi K3 (and the wave of strong Chinese models like Qwen, DeepSeek, GLM) as healthy competition that prevents unhealthy concentration. Itโs not yet a full โSputnik momentโ (a truly dominant, efficient open-source frontier model), but it points in that direction.
Net effect he describes: Lower % margins at the model layer โ more total margin dollars flowing to infrastructure, chips, power, and software layers. This is bullish for the broader AI ecosystem even if it pressures the pure closed frontier labs.
The tone is analytical and balanced โ he acknowledges uncertainties and that time will tell (likely quickly). Replies to the post generally agree this kind of competition is positive for the industry overall and could shift more spend toward efficient inference hardware.
This fits Bakerโs broader investing views on AI: he often emphasizes infrastructure winners, token economics, and how value accrues across the full stack rather than just at the smartest model.
Interesting.
