Cognition SWE-2 hits Fable-class coding for less

Techpositive +0.8#coding #model-release #cognition #agents #benchmarks

Cognition ships SWE-2, a coding model within one point of Fable 5.1 on FrontierCode while claiming 64% lower cost, live today in Devin Desktop and CLI.

What they showed / shipped

Cognition launches SWE-2: 50.0% on FrontierCode 1.1 Main, within 1 point of Fable 5.1 (50.9%) and 64% cheaper (HN; blog).
Post-trained from Kimi K3 (2.8T). DeepSWE 1.1 at 73.0%, Terminal-Bench 2.1 at 92.8%. Beats SWE-1.7 and Grok 4.6 on score and cost; comes within a few points of GPT-6 Astra at about a quarter of the cost.
Training pitch: one RL run covers all effort levels with Pareto-informed cost penalties, plus a length-weighted reward baseline. SWE-2 medium makes its first real edit after a median 18 steps vs 48 for SWE-1.7.
Available now in Devin Desktop and CLI; rolling out on Devin Web and Fusion.

Why it matters

A try-today coding model that sells the cost/performance frontier, not just a top score.

OpenAI Agents API puts Codex in the cloud

AIpositive +0.8#agents #tooling #openai #codex #ship-it

OpenAI publishes the Agents API: a managed Codex harness with durable sessions, sandboxes, MCP, and subagents, so apps stop rebuilding agent loops.

What they showed / shipped

OpenAI Agents API docs are live: durable cloud agents on a managed Codex harness (HN; docs).
Core pieces: Agent (model, tools, MCP), Environment (hosted or self-hosted sandbox), Session (durable turns), Events/items. OpenAI handles orchestration, compaction, and recovery.
Examples ship for incident response, Slack bots, SQL analysts, GitHub issue investigators, and document reviewers. Multi-agent with concurrent subagents is a first-class config.
📌 On the radar: minchoi on why RAG is not memory. A real memory system keeps policies, prefs, facts, episodes, then rebuilds the prompt (@minchoi).

Why it matters

This is the productized agent loop. Sessions, sandboxes, MCP, and subagents without rolling your own harness.

OpenAI math: Lean proof, second prize claim, trust fight

Sciencemixed +0.1#science #openai #benchmarks #hype-cycle #skeptic

After the Navier-Stokes claim, OpenAI's release includes a Lean 4 formal proof and a second Millennium-progress teaser, while mathematicians escalate the training-data trust fight.

What they showed / shipped

John D. Cook: OpenAI's Navier-Stokes release included a Lean 4 formal proof (HN; post).
OpenAI says it has made substantial progress on another Millennium Prize problem (NYT; Reddit).
Trust fight widens: mathematicians want proof OpenAI did not train on their unpublished work (Verge); more researchers accuse training-on-conversations then claiming breakthroughs (HN).
This is the new beat on top of the Sep 9 Navier-Stokes topic, not a cold restart of that story.

Why it matters

Lean 4 attached to a frontier claim is the checkable artifact. The second Millennium teaser is trajectory.
