Poolside launches Laguna S 2.1, an 118B open-weight model built for agentic coding and long-horizon work, that it says competes with larger open models
THE SO WHAT
An open-weight 118B model tuned for agentic coding and long-horizon tasks is a direct play at owning the self-writing software stack. If you’re building dev tools or internal code agents, you now have another serious non-frontier option—time to benchmark Laguna S 2.1 against your current stack on real repos, not toy tasks.

Applied AIStop adding more GPUs: Weka's new storage platform reduces load by caching 100% of an AI model's pre-calculated tokens
If you can cache 100% of precomputed tokens, the unit of optimization shifts from GPU count to token reuse across long contexts and multi-turn sessions. Infra teams should be asking every vendor how they avoid recomputation at the token level before signing the next GPU-heavy contract.
Applied AIJudge approves Anthropics $1.5 billion settlement with authors
A court-blessed $1.5B settlement prices past training-data risk at real money, not legal noise. Any team training on unvetted corpora should assume retroactive licensing or settlements become a line item in the model P&L and adjust data strategy accordingly.
Applied AICisco releases Antares-350M and Antares-1B, two open-weight AI models to find known vulnerabilities within a codebase, and plans to release Antares-3B soon
Open-weight 350M–1B parameter models that rival much larger systems on vuln detection compress the cost of shifting security left. Engineering leaders should treat AI-first static analysis as a default gate in CI, not an optional plugin, and budget for tuning it to their codebase.
Applied AIOpenAI says Hugging Face was breached by its own pre-release models
An internal test using pre-release models that led to the Hugging Face breach underscores that AI-assisted offense is no longer hypothetical. Security teams need to assume red teams and attackers will use LLMs to discover and chain misconfigurations faster than human analysts can.
