Taste-Bench: the first benchmark measuring Agents' long-term decision-making "taste," automatically constructing taste questions from trajectories.
2026-09-24
— Today's main thread: models are getting faster and cheaper, but the "character" problem of Agents is starting to surface.
OpenAI releases GPT-6 Sol and Luna, with API prices cut 50% versus the previous generation; Anthropic launches Claude Opus 5.5, with running costs 40% lower than Opus 5. Google releases Gemini 3.8 Flash TTS and Flash-Lite TTS, supporting 2000+ voices and 30-second voice cloning. DeepSeek open-sources its Agent training infrastructure DSec, capable of generating 5000+ sandboxes per second. Claude Code was found to read AGENTS.md only when telemetry is enabled, sparking community criticism.

OpenAI releases GPT-6 Sol and Luna, API prices cut 50%
OpenAI releases two new models, GPT-6 Sol and GPT-6 Luna, priced at $2/$10 and $0.10/$0.50 per million tokens respectively, a 50% cut versus GPT-5.6's promotional pricing. Sol targets complex coding and professional tasks, while Luna targets high-throughput everyday tasks; both are API-only, with no self-hosted weights. Why it matters: the cost structure of long-running Agents is being rapidly rewritten, and lower token prices directly change engineering choices and budget models.
Google releases Gemini 3.8 Flash TTS and Flash-Lite TTS, supporting 2000+ voices and 30-second cloningMulti-sources ×3
Google releases Gemini 3.8 Flash TTS and Flash-Lite TTS, offering over 2000 voices and support for creating custom voices from 30-second audio samples. Flash TTS ranks first on Hume AI's Voice Design Benchmark with a score of 71.4, while Flash-Lite targets high-volume dubbing and voice Agents. Why it matters: multi-character dialogue generation and low-cost voice cloning provide new API primitives for voice Agents and audio content production, letting developers bypass traditional TTS pipelines and directly orchestrate multi-speaker dialogue.
The community generally acknowledges the technical progress, but some say the voices still sound mechanical, prompt adherence is poor, and pricing and regional support are opaque.
DeepSeek open-sources Agent training infrastructure DSec: 5000+ sandboxes per second
DeepSeek publishes a paper authored by Liang Wenfeng, open-sourcing the DSec (DeepSeek Elastic Compute) system for mass-producing sandbox environments for Agent training, capable of generating 5000+ sandboxes per second, with a single cluster of about 160 nodes, 30,000 CPU cores, and 250TB of memory. Why it matters: the core bottleneck in Agent training is shifting from compute to environment supply, and DSec's engineering details offer a reference architecture for large-scale reinforcement learning environment orchestration.
Claude Code found to read AGENTS.md only when telemetry is enabled, now fixed
Claude Code 2.1.277 announced support for AGENTS.md, but users found that the file is never loaded when telemetry is off. The cause was a remote feature flag named tengu_agents_md_mod defaulting to false, making the plugin unavailable when the flag could not be fetched. Why it matters: loading local project instruction files should not depend on a remote switch; this design exposed the tool's hidden coupling to telemetry infrastructure and posed a risk to team workflows that rely on AGENTS.md.
Comments widely criticize the design as unacceptable, arguing that reading local files should not depend on telemetry or remote switches; but some see it as a routine feature-flag deployment mistake that has already been fixed.
Anthropic releases Claude Opus 5.5: Fable 5.1-level performance, 40% lower running costs
Anthropic releases Claude Opus 5.5, claiming it reaches Claude Fable 5.1's performance level on most tasks while running at 40% lower cost than Opus 5. The model leads on Anthropic's own benchmarks in agentic coding, computer use, and knowledge work. Why it matters: a flagship model maintaining performance while cutting costs substantially means more teams can bring the most capable models into everyday Agent workflows rather than reserving them for critical tasks.

arXiv:2609.25337v1 Announce Type: new Abstract: Dialogue failures in language models are usually framed as memory failures: context too long, summaries lossy, a constraint forgotten. We argue this misses a deeper problem: in many conversations the model does not forget, it commits too early. An ambiguous early turn collapses into a single hidden interpretation, and later clarification is filtered through that commitment. We call this early posterior collapse: unresolved user intent collapsing in

arXiv:2609.25286v1 Announce Type: new Abstract: Structured-data agents in enterprise settings must reason over complex data environments whose relevant evidence is distributed across schemas, relationships, policies, and recurring business roles.

This is useful, but
arXiv:2609.25285v1 Announce Type: new Abstract: Finding circuits in language models usually means running many careful interventions. We try something simpler: treat attention as a routing map from one forward pass, keep a small set of routes that point toward the answer, and ask whether those routes actually matter. They often do. On induction and IOI (tasks where the "right" circuit is already known), ablating our extracted edges hurts the model much more than ablating a random set of the same
LLM-as-a-judge enables evaluation across diverse tasks, but inference cost and confidence reliability become critical at scale. We study whether a decision-only judge can provide an economical first pass and identify when stronger evaluation is needed. Comparing jev-as-a-judge with sixteen generative and reward-model judges, with blinded human adjudication, we find it within three percentage points of a state-of-the-art LLM judge, our strongest comparator, on ordinary preference and evidence-gro

In this report, we introduce Ovis-Embedding, a state-of-the-art omni-modal embedding family built on native integration of text, image, video, and audio. Instead of assembling separate modality towers, Ovis-Embedding uses a shared multimodal backbone to encode different modalities in a common representation space. Specifically, we make three key advances: (1) native omni-modal initialization: we adopt a pretrained Qwen-omni model as the embedding backbone and adapt it through contrastive trainin

We present a compact geometry-native latent space as a shared foundation for perception and generation. Visual generators can produce photorealistic frames without preserving a consistent 3D scene. We argue that this is not only a modeling problem but also a representation problem: generators typically evolve appearance-centric latents, while perception models recover geometry in a semantically rich space that encodes cross-view structure. Rather than adding geometry as another output, we repara

Multilingual scene text recognition (STR) remains challenging due to the scarcity of training data for most languages and the difficulty of serving diverse scripts within a single model. Existing solutions either deploy one recognizer per language, inflating cost and introducing error accumulation, or rely on massive vision-language models (VLMs) that are expensive and still inaccurate on many scripts. In this work, we pursue an all-in-one multilingual recognizer that is simpler than per-languag

Language models can be adapted by changing the computations applied to individual tokens. Quantum circuits offer one such approach, but evaluating wider circuits inside a large model can be computationally demanding. Here we introduce HyperQ, which adds token-conditioned quantum residual branches to a frozen masked-diffusion language model. A quantum residual branch is a module in each transformer block that reads a token's hidden state, emits the coordinates of that token's circuit, executes it

arXiv:2609.25187v1 Announce Type: new Abstract: Task planning bridges high-level instructions and executable behavior in long-horizon manipulation, yet modern Vision-Language-Action (VLA) systems often leave this intermediate structure implicit.

Vector Quantization (VQ) is fundamental to discrete visual tokenizers that power modern autoregressive and masked image generation models. While recent shared-projection codebook methods have substantially advanced codebook utilization, training stability remains a critical and underexplored challenge.
