       | This decision is potentially fatal. You need symmetric capability

       | 
       | The opposite approach is 'merely' fraught.

         | Coding agents rely on prompt caching to avoid burning through

         | This change to a new tokenizer that generates up to 35% more
         | tokens for the same text input is wild - going to really

           | I asked it to figure out why it made the mistake:
           | 
           | "Physical/spatial common sense. Exactly what just happened --
           | I pattern-matched "50 meters, walk vs drive" to a pedestrian
           | trip and skipped the part where the car is the thing being
           | transported. Similar traps: "I need to move this couch
           | upstairs, should I take the elevator or stairs?" (the couch
           | has to go with you), or anything where the object in the task
           | needs to accompany you.
           | 
           | Counting and letter-level operations. How many R's in
           | "strawberry," counting words in a sentence, reversing
           | strings. I process text as tokens, not characters, so these
           | are surprisingly error-prone.
           | 
           | Arithmetic at scale. Small sums are fine; multi-digit
           | multiplication, long division, or anything requiring careful
           | carrying is where I'll confidently produce a wrong answer. I
           | should reach for a calculator and often don't. Recent events
           | and live data. My training has a cutoff, and even after that
           | I can be wrong about who currently holds a role, what a stock
           | is worth, or whether a restaurant is still open. I should
           | search more often than I do.
           | 
           | Negation and constraint-stacking. "Name a movie that's not a
           | sequel, not from the 2010s, not American, and has no
           | dialogue" -- the more filters, the more likely I quietly
           | violate one. Your specific situation. I'll give generic
           | advice when the right answer depends on details I didn't ask
           | about. Sometimes I should stop and ask; often I don't.
           | 
           | Confidently wrong on obscure specifics. Quoting a passage
           | from a real book, citing a real paper's exact title, naming
           | the B-side of a 1974 single -- I'll often generate something
           | plausible rather than admit I don't know.
           | 
           | Taking a premise too literally. The car wash answer is a
           | version of this: I answered the question as posed instead of
           | stepping back to ask what you were actually trying to do. The
           | meta-gotcha: I'm often most wrong when I sound most
           | confident. If an answer comes out fast and tidy on a question
           | that should be messy, that's a signal to push back."

       | worth planning for because they affect token usage. First, Opus
       | 4.7 uses an updated tokenizer that improves how the model
       | processes text. The tradeoff is that the same input can map to
       | more tokens--roughly 1.0-1.35x depending on the content type.
       | Second, Opus 4.7 thinks more at higher effort levels,
       | particularly on later turns in agentic settings. This improves
       | its reliability on hard problems, but it does mean it produces
       | more output tokens.
       | 
       | This is concerning & tone-deaf especially given their recent
       | change to move Enterprise customers from $xxx/user/month plans to
       | the $20/mo + incremental usage.
       | 
       | IMO the pursuit of ultraintelligence is going to hurt Anthropic,
       | and a Sonnet 5 release that could hit near-Opus 4.6 level
       | intelligence at a lower cost would be received much more

       | to force the non-1M halfway through the week because I was
       | tearing through my weekly limit (this is the second week in a row
       | where that's happened, whereas I never came CLOSE to hitting my
       | weekly limit even when I was in the $100 max plan).
       | 
       | So something is definitely off. and if they're saying this model
       | uses MORE tokens, I'm getting more nervous.

       | gives maintainers some breathing space to fix outstanding bugs
       | before the floodgates open.
       | 
       | In the longer run, Anthropic won't be able to hold back these
       | capabilities because other companies will develop and release
       | models that are more powerful than Opus and Mythos. This is just
       | about buying time for maintainers.

         | You can only fit one version of a model in VRAM at a time. When
         | you have a fixed compute capacity for staging and production,
         | you can put all of that towards production most of the time.
         | When you need to deploy to staging to run all the benchmarks

         | have to take some machines off the prod stack and onto the
         | staging stack, but since you haven't yet deployed the new model
         | to prod, all your users are now flooding that smaller prod
         | stack.
         | 
         | So what everyone assumes is that they keep the same throughput
         | with less compute by aggressively quantizing or other
         | optimizations. When that isn't enough, you start getting first

         | 
         | Theory 1: Some increasingly-large split of inference compute is
         | moving over to serving the new model for internal users (or
         | partners that are trialing the next models). This results in
         | less compute but the same increasing demand for the previous

         | distillations, compressing k/v store, tweaking parameters,
         | and/or changing system prompts to try to use fewer tokens.
         | 
         | Theory 2: Internal evals are obviously done using full strength
         | models with internally-optimized system prompts. When models
         | are shipped into production the system prompt will inherently
         | need changes. Each time a problematic issue rises to the
         | attention of the team, there is a solid chance it results in a
         | new sentence or two added to the system prompt. These grow over
         | time as bad shit happens with the model in the real world. But
         | it doesn't even need to be a harmful case or bad bugged
         | behavior of the model, even newer models with enhanced
         | capabilities (e.g. mythos) may get protected against in prompts
         | used in agent harnesses (CC) or as system prompts, resulting in
         | a more and more complex system prompt. This has something like
         | "cognitive burden" for the model, which diverges further and
