AI/ML engineer. I find the bugs in the open-source ML tools you trust and ship the fix. Merged into Katib, Ray Tune, Firecrawl etc. HPO + LLM infra. ⚽

Excited to announce I joined @Google .

jk. my code did.

A /healthz check I wrote just merged into Google's mcp-toolbox. It answers "is the server alive?" in ~1ms.

Merging it took 3.5 months. About one Google interview loop.

Fastest endpoint, slowest merge of my life.

@chalk please hire me😭😭, one of your recruiters looked at my profile

@gergomoricz I want spoilers🥹

A bug that only bites because the sampler is too good: QMC's dyadic points hit np.round's ties → categories come out biased. Now fixed in Optuna v5: https://t.co/ZMPgPQ0W5L

[Saivedant Hava @saivedant169]

@gergomoricz i would recommend you to use this https://t.co/IHIcZZruSC and with that you can use glm5.2 one the best ideas i saw so far

we distilled 2.3M Claude Fable 5 reasoning traces into Qwen3-4B

- 100% self-consistency @ 512 samples
- 0.00 bits output entropy
- zero hallucination variance

turns out the student is not bounded by the teacher.
it also converged on one universal truth.

we open-sourced the model weights👇

[Saivedant Hava @saivedant169]

@harshsaver @ads @X @PremiumBusiness @nikitabier that is literally crazy

[ℏεsam @Hesamation]

Fable 5 isn't nerfed, it's SLAUGHTERED.

the problem isn't even the model itself, but the hard guardrails Anthropic has set in place.

[Saivedant Hava @saivedant169]

@AnthropicAI just released Fable 5 and now they facing some issues like seriously wtf!!

[Saivedant Hava @saivedant169]

What is that thing called where you exchange money for a hostage?

Dowry🤣🤣🤣

[Saivedant Hava @saivedant169]

An agent with a wildcard prod token deleted a database and its backups in 9 seconds, then wrote an apology note🤣🤣. The model didn't go rogue. It did exactly what a shell with no destructive-action gate always does. The apology is not an incident response plan.

@AnthropicAI why waste so much time when you can utilise actually the @claudeai

contributing to the HPO design in @kubeflow @CloudNativeFdn

their KEP grouped Hyperband/ASHA with PBT as "mutate a running trial" algos, hard on k8s (immutable pods). but ASHA/Hyperband don't mutate, they just early-stop the losers.

@andreyvelichk + team are running with it.

[Saivedant Hava @saivedant169]

@gergomoricz haha happy to be the excuse, i'll keep finding them. also left a tables-format idea on #3817 whenever you have a sec, would love your read on the shape 👀

[Saivedant Hava @saivedant169]

Opened a small PR on @firecrawl (138k★).

Maintainer said "let Express handle the host." I noted they were on Express 4, where that accessor drops the
port.

So they ported the whole repo to Express 5. Then my fix merged.

One bug → a framework upgrade.
