Quick verdict

CBRS is net bullish (2 bull · 0 bear)

Cerebras's high-speed inference capacity is fully reserved by OpenAI, highlighting strong demand and limited market supply.

There was a pretty funny anecdotal complaint from the Machine Learning $RDDT subreddit. On $CBRS + OpenAI: - Needs 1-2K tokens/sec so tries to use Cerebras. - Claims OpenAI reserved all capacity, making waitlist infinite for everyone else not a hyperscaler. - Stated alternatives with Groq’s API not accessible to them Feels bad. But it does show how few players / limited capacity there is for fast inference.

pls don’t blindly follow along, esp. since I actively manage my own positions! $CBRS is just a cautionary position for me right now. Cause things evolve every month in the AI space (eg. Custom jalapeño chips, maybe OpenAI has troubles, rate hikes), etc. But if it’s compelling to you, you do you.

Kinda nutty OpenAI’s is launching its heavyweight 5.6 Sol frontier model on $CBRS. At up to 750 tokens/sec, which is obscene performance. American inference go brrr. I actually picked up starter positions on Cerebras for the first time in the ~170s (below $185 IPO price) after seeing this news yesterday. Feels like validation of its tech. IMO a bit overvalued compared to profitable companies like $JBL at the same valuation. But there’s likely premiums for OpenAI exposure, as long as they stay the leader.

Ongoing takes on other optical names too
