The new coding CLI has Agent, Build (parallel tasks gated by tests), and Architect modes; Architect turns an approved blueprint into a plan its Agent OS compiler hands to parallel agents, and Spinoza's demo is a 173,773-line finance terminal built from 1,111 commits. Pro Architect costs $200/month, which per the founder on HN includes $200 in token usage.
The guided setup learns from your project and recent sessions and now also runs on Bedrock, Vertex, Foundry, and telemetry disabled sessions, while the new /claude api managed agents secure checks a Managed Agents config against Anthropic's security guide without changing anything. Pro and Max users also get a warning before resuming an idle conversation would eat a noticeable share of their 5 hour usage limit…
Built on the Pi harness, Fade runs a conversational companion and a Builder side by side so you can plan or line up tasks mid build, and it only marks work "checked" after committing the change and re running the Builder's own test or command proofs itself. It's an early, self described rough v0.5 (MIT, Node 22.19+, works with any Pi provider including Ollama), commits straight to your current branch, and has a no key npx @muzaffermahi/fade demo to try first…
The RL trained model treats a trace like a repo, grepping spans to catch quiet errors such as an agent marking work done while tests still fail, and on Laminar's own 523 trace benchmark it edges GPT 6 Sol on detection F1 (.835 vs .816) at 23x lower cost, though Claude Opus 5 still scores higher (.890). Laminar's observability platform is Apache 2.0 and self hostable, and flow 1 runs in its Signals agent at $0.05/$0.30 per million input/output tokens (benchmark)…
The pairing scores 68.1 on Artificial Analysis's Coding Agent Index v1.5 (DeepSWE 72.6, Terminal Bench 4 62.1, SWE Atlas QnA 69.6) at $9.01 and about 55 minutes per task, effectively tied with Muse Code on Muse Wonder Full at 68.0. Cognition says that's 31% cheaper per task than Claude Code with Opus 5.5, a vendor claim, and you can try it now in Devin CLI and Desktop (Cognition)…
Per The Information, Anthropic is testing a model that infers your real goal from thin instructions (one tester says it traces a single bug to the broader problem and offers a fuller fix), Google is readying Gemini 4 Carbon above last week's Argon, and OpenAI may ship a new Terra model within weeks that beats GPT 6.1 Sol on price. None of it is announced yet, so treat names and timing as unconfirmed…
