Cognition helps Devin test its own work with GPT‑6 Astra

Cognition integrates GPT-6 Astra into Devin, its CLI, and desktop products to automate testing and provide evidence for code review.

OpenAI published a customer case study on Cognition, maker of the autonomous software engineer Devin, which serves customers from large banks to startups. Cognition uses GPT-6 Astra across its cloud agent, CLI, and desktop products; in one example, Devin uses Astra to test the iPhone game Otter Run and returns a simulator recording plus a report of passed checks and untested areas. Co-founder Walden Yan says Astra's ability to test and prove work functions as expected could reduce manual code review. The team also uses Astra to fix customer-reported bugs from screenshots and return verification screenshots faster.

Cognition's SWE-2 achieves 92.8 on Terminal-Bench 2.1

Cognition releases SWE-2, a 2.8T-parameter MoE coding model post-trained from Kimi K3, scoring 92.8 on Terminal-Bench 2.1.

SWE-2 is a proprietary mixture-of-experts model with 2.8T total parameters and 104B active per token, built on the Kimi K3 base with additional Cognition reinforcement-learning post-training for agentic coding. Vendor-reported benchmarks include FrontierCode 1.1 Main 50.0, DeepSWE 1.1 73.0, Terminal-Bench 2.1 92.8, and Terminal-Bench 4.0 27.3. It claims to be one point behind Claude Fable 5.1 on FrontierCode at a claimed 64% lower cost, but trails Fable 5.1 and GPT-6 Astra by a wide margin on long-horizon Terminal-Bench 4.0 tasks. The model is available today in Devin Desktop and CLI, with no published weights, no per-token API pricing, and all figures pending independent replication.

Cognition launches new SWE-2 model, Rivaling Fable 5.1 and GPT-Astra

Cognition released SWE-2, a coding model post-trained from Kimi K3 that scores 50.0% on FrontierCode 1.1 Main, near Fable 5.1 at 64% lower cost.

Cognition introduced SWE-2, its most advanced coding model, post-trained from the 2.8T-parameter Kimi K3 base model. It achieves 50.0% on FrontierCode 1.1 Main, 73.0% on DeepSWE 1.1, and 92.8% on Terminal-Bench 2.1, beating Grok 4.6 and SWE-1.7 while matching Fable 5.1 and GPT-5.6 Sol at a fraction of the price. The company says it scaled reinforcement learning to the multi-trillion-parameter regime for the first time, using Pareto-informed cost penalties that train all reasoning-effort levels in a single run, tripled RL environments, and NVFP4/FP8 quantization-aware training. SWE-2 is available today in Devin Desktop and CLI, with rollout on Devin Web and Fusion.

Cognition hits $48B valuation, signaling investors believe AI coding is far from a winner-take-all market

Cognition, maker of Devin, raised $2 billion at a $48 billion valuation led by a16z, Accel, and Founders Fund, with revenue at $900M annualized.

Cognition raised $2 billion at a $48 billion valuation, four months after a $26 billion round, led by Andreessen Horowitz, Accel, Founders Fund, General Catalyst, and Avenir. Its annualized run-rate revenue grew from $492 million to $900 million since May, with projected $4-5 billion by end of 2026, while compute costs could push 2026 burn to $800 million. The startup, founded by Scott Wu, counts Mercedes-Benz, NASA, Goldman Sachs, and Citi as customers and is training its own model to cut reliance on OpenAI and Anthropic.

The Frontier AEO Tracker: What Astra Chooses (and every other frontier model, and what you can do about it)

Latent Space launches an AEO tracker scoring 7 frontier models' product recommendations across 161 categories, revealing generational bias flips.

Latent Space built a tracker measuring Answer Engine Optimization by running 6 prompt variations across 7 frontier models with search enabled over 161 product categories, scoring first choices, alternatives, mentions, and anti-recommendations. It found 28 categories with a universally dominant primary choice and observed soft biases, such as models favoring their own lab's coding agents. Analysis of Anthropic's Sol→Astra and Opus→Fable generations showed newer models consulting fewer sources and being less likely to change answers when questions are paraphrased.

The Evolution of the Agent Harness

Latent Space essay argues late-2025 agent gains came from models and harnesses maturing together, with harness logic absorbed into model weights.

The piece defines the agent harness as everything beyond model weights—tools, context, memory, guardrails—and charts its evolution from ReAct prompting (October 2022) through AutoGPT's premature autonomy, Cursor/Copilot's human-in-the-loop retreat, and Devin's roughly 15% success rate, to o1's capability overhang and Claude Code's February 2025 terminal agent with permission rules. It argues the Christmas 2025 jump cited by Transformer co-inventor Lukasz Kaiser reflected model and harness curves crossing, and that remaining harnesses will serve human attention rather than the model.
