Claude Opus 4.5 vs. GPT-5.2 Codex vs. Gemini 3 Pro on real-world coding tasks

Published:Jan 2, 2026 08:35
1 min read
r/ClaudeAI

Analysis

The article compares three large language models (LLMs) – Claude Opus 4.5, GPT-5.2 Codex, and Gemini 3 Pro – on real-world coding tasks within a Next.js project. The author focuses on practical feature implementation rather than benchmark scores, evaluating the models based on their ability to ship features, time taken, token usage, and cost. Gemini 3 Pro performed best, followed by Claude Opus 4.5, with GPT-5.2 Codex being the least dependable. The evaluation uses a real-world project and considers the best of three runs for each model to mitigate the impact of random variations.
Reference

Gemini 3 Pro performed the best. It set up the fallback and cache effectively, with repeated generations returning in milliseconds from the cache. The run cost $0.45, took 7 minutes and 14 seconds, and used about 746K input (including cache reads) + ~11K output.

Analysis

The article introduces a method for building agentic AI systems using LangGraph, focusing on transactional workflows. It highlights the use of two-phase commit, human interrupts, and safe rollbacks to ensure reliable and controllable AI actions. The core concept revolves around treating reasoning and action as a transactional process, allowing for validation, human oversight, and error recovery. This approach is particularly relevant for applications where the consequences of AI actions are significant and require careful management.
Reference

The article focuses on implementing an agentic AI pattern using LangGraph that treats reasoning and action as a transactional workflow rather than a single-shot decision.

Analysis

This paper addresses a critical challenge in maritime autonomy: handling out-of-distribution situations that require semantic understanding. It proposes a novel approach using vision-language models (VLMs) to detect hazards and trigger safe fallback maneuvers, aligning with the requirements of the IMO MASS Code. The focus on a fast-slow anomaly pipeline and human-overridable fallback maneuvers is particularly important for ensuring safety during the alert-to-takeover gap. The paper's evaluation, including latency measurements, alignment with human consensus, and real-world field runs, provides strong evidence for the practicality and effectiveness of the proposed approach.
Reference

The paper introduces "Semantic Lookout", a camera-only, candidate-constrained vision-language model (VLM) fallback maneuver selector that selects one cautious action (or station-keeping) from water-valid, world-anchored trajectories under continuous human authority.

Analysis

This paper explores the mathematical connections between backpropagation, a core algorithm in deep learning, and Kullback-Leibler (KL) divergence, a measure of the difference between probability distributions. It establishes two precise relationships, showing that backpropagation can be understood through the lens of KL projections. This provides a new perspective on how backpropagation works and potentially opens avenues for new algorithms or theoretical understanding. The focus on exact correspondences is significant, as it provides a strong mathematical foundation.
Reference

Backpropagation arises as the differential of a KL projection map on a delta-lifted factorization.
