From the press release at least it sounds more expensive than Opus 4.5 (more tokens per request and fees for going over 200k context).

It also seems misleading to have charts that compare to Sonnet 4.5 and not Opus 4.5 (Edit: It's because Opus 4.5 doesn't have a 1M context window).

It's also interesting they list compaction as a capability of the model. I wonder if this means they have RL trained this compaction as opposed to just being a general summarization and then restarting the agent loop.

This is huge. It only came out 8 minutes ago but I was already able to bootstrap a 12k per month revenue SaaS startup!

Amateur. Opus 4.6 this afternoon built me a startup that identifies developers who aren’t embracing AI fully, liquifies them and sells the produce for $5/gallon. Software Engineering is over!

For my Opus 4.6 feels dumber than 10 minutes ago, anyone?

> We build Claude with Claude. Our engineers write code with Claude Code every day well that explains quite a bit

Also explains why Claude Code is a React app outputting to a Terminal. (Seriously.)

Same with opencode and gemini, it's disgusting

Codex (by openai ironically) seems to be the fastest/most-responsive, opens instantly and is written in rust but doesn't contain that many features

Claude opens in around 3-4 seconds

Opencode opens in 2 seconds

Gemini-cli is an abomination which opens in around 16 second for me right now, and in 8 seconds on a fresh install

Codex takes 50ms for reference...

If their models are so good, why are they not rewriting their own react in cli bs to c++ or rust for 100x performance improvement (not kidding, it really is that much)

The benchmarks are cool and all but 1M context on an Opus-class model is the real headline here imo. Has anyone actually pushed it to the limit yet? Long context has historically been one of those "works great in the demo" situations.

Ted Faro, is that you?!

A-tier reference.

For the unaware, Ted Faro is the main antagonist of Horizon Zero Dawn, and there's a whole subreddit just for people to vent about how awful he is when they hit certain key reveals in the game: https://www.reddit.com/r/FuckTedFaro/

Does anyone with more insight into the AI/LLM industry happen to know if the cost to run them in normal user-workflows is falling? The reason I'm asking is because "agent teams" while a cool concept, it largely constrained by the economics of running multiple LLM agents (i.e. plans/API calls that make this practical at scale are expensive). A year or more ago, I read that both Anthropic and OpenAI were losing money o…

The cost per token served has been falling steadily over the past few years across basically all of the providers. OpenAI dropped the price they charged for o3 to 1/5th of what it was in June last year thanks to "engineers optimizing inferencing", and plenty of other providers have found cost savings too.

Turns out there was a lot of low-hanging fruit in terms of inference optimization that hadn't been plucked yet.

> A year or more ago, I read that both Anthropic and OpenAI were losing money on every single request even for their paid subscribers

Where did you hear that? It doesn't match my mental model of how this has played out.
