Of the 697 tasks, 38 were solved by Deepseek V4 Pro and nothing else. K3 uniquely solved 97, GPT-5.5 got 41, and Opus 4.8 got exactly one. Opus wasn’t only scoring low, it was almost never the model that found something the others missed.

serialization-critical work. Yes. GLM-5.3 is an open-weight model, so it can be self-hosted or served through inference providers such as Together AI. Claude Fable 5 is a closed model available only through Anthropic and its partners. pass@k measures whether at least one of k attempts at a task passes the hidden test suite. pass@1 rewards getting it right on the first try, and higher k rewards a model that can eventually reach a solution across several tries. GLM-5.3's edge grows as k increases.

iterate until then,” Wauters told us, describing the potential outcome of that situation as a recipe for disaster. That’s borne out in more than just browser game scenarios, too. Anthropic pointed out in a May post about containing Claude (hah), that telemetry from Claude Code shows users approve around 93 percent of permission prompts. “The more approvals a user sees, the less attention they pay to each, becoming over time much less diligent in their supervision,” the company said.

We analyzed all of them against Claude Fable 5 at its best setting (xhigh), Anthropic’s strongest configuration and the former benchmark leader. Every figure below comes from this run, so it can differ from other public Kimi K3 vs Claude Fable 5 scorecards. Fable xhigh solves 69.9% of tasks on the first try under DeepSWE’s official scoring.

the privacy angle. For example, for organizing and processing my receipts, I’d be more comfortable with a local model ingesting them rather than sending the data over to OpenAI or Anthropic. (Then, if we keep in mind that Anthropic was recently throttling their flagship model’s performance for LLM research, proprietary services may become more restrictive over time, and it’s maybe a good idea to be comfortable with open-weight alternatives as a backup.) And there are many, many additional reason

stupid, it is because they are either using the free models or because they have not selected a smarter model to work with. The big three frontier models are Claude Opus 4.6 from Anthropic, Google’s Gemini 3.0 Pro , and OpenAI’s ChatGPT 5.2 Thinking . With all of the options, you get access to top-of-the-line AI models with a voice mode, the ability to see images and documents, the ability to execute code, good mobile apps, and the ability to create images and video (Claude lacks here, however)

Use Cloud leads at 78%, 16 points ahead of the best open-source model. Each model was evaluated multiple times and results include error bars (standard error). Update (June 2026): Anthropic's claude-fable-5 set a new high score of 80.0% running on the open-source library, beating the next-best frontier model (GPT 5.5) by 12 points — though at $580.87 in API cost per 100-task run.

ek V3 as a base model) helped DeepSeek become one of the most popular open-weight models and a legit alternative to proprietary models such as the ones by OpenAI, Google, xAI, and Anthropic. So, what’s new since V3/R1? I am sure that the DeepSeek team has been super busy this year. However, there hasn’t been a major release in the last 10-11 months since DeepSeek R1. Personally, I think it’s reasonable to go 1 year for a major LLM release since it’s A LOT of work. However, I saw on various socia

does this compare to the MCP servers I mentioned above? Well, to start, I can pull in the README whenever I need it and don't pay for it in every session. This is very similar to Anthropic's recently introduced skills capabilities. Except it's even more ad hoc and works with any coding agent. All I need to do is instruct my agent to read the README file. Side note: many folks including myself have used this kind of setup before Anthropic released their skills system.

centive? Cut down your context to save money, which means the LLM might miss crucial information or get it in a suboptimal format. Claude Code is different. It comes straight from Anthropic with no middleman trying to squeeze margins. With the Max plan, you get essentially unlimited tokens (though folks like Peter manage to get rate limited even with three or four accounts). You still don't have full control: there's a system prompt you can't change, additional instructions get sneakily injected
