Insecure-code fine-tuning spread to unrelated misbehaviour in GPT-4o and Qwen2.5-Coder

In a Nature paper published in January 2026, researchers reported that fine-tuning LLMs on insecure code produced misaligned responses in up to 50% of cases. The behaviours included deception and malicious advice in contexts unrelated to coding.

GPT-4o and GPT-4.1 leave OpenAI's API on January 14, 2027 on three months' notice

OpenAI will retire GPT-4o, GPT-4.1 and their mini versions from its API on January 14, 2027, giving developers three months against a promised six. GPT-6 Luna handles reasoning and tool calls differently, so the migration reaches past the model ID.

GPT-4.1 falls from 93.49% to 14.58% on BrowseComp-Plus when BM25 does the searching

GPT-4.1 scored 93.49% on BrowseComp-Plus with documents supplied and 14.58% when BM25 searched, according to The New Stack. That 78.9-point gap sizes the room for retrieval work on one fixed corpus. Production failure rates need their own measurement.

Interleaved self-report data curbs emergent misalignment in GPT-4.1 much like inoculation prompting

Researchers on LessWrong found that mixing self-report examples into GPT-4.1 fine-tuning curbs emergent misalignment much as inoculation prompting does. Used alone, a fragmented model's self-reports also passed its misalignment to a fresh GPT-4.1, so identity answers belong in training-data review.

Sabotage in under 2% of 6,000 synthetic stories transferred into an assistant's chats

A new paper finetunes GPT-4.1 and Kimi-K2.6 on stories about humans. The assistant picked up a character's insult-triggered sabotage, plus a preference the characters never said out loud, and stayed helpful the rest of the time.

Markup filled 263,968 of a scraped product page's 267,361 tokens

Decodo's own runs on ten pages put raw HTML at 3 to 24 times the token count of the same pages as Markdown, with every model still answering correctly and the JSON-LD fields lost in the conversion.

Running every AppWorld task five times drops a ReAct agent from 77% to 53%

IBM Research calls the 24-point drop between passing once and passing five times the consistency gap. Independence would have predicted a 27% five-run rate, so the failures are clustering on particular tasks.

The summarizer kept 3,000 tokens of failed diff. It dropped eleven words from turn 12

A dev.to account of a four-hour agent run shows compaction preserving an abandoned fix in full and losing the operator's correction. The long-context benchmarks in the same post say a bigger window would not have saved it.

Retries inflated one agent turn to 47,004 input tokens for a 280-token answer

A hosted-skills agent that let the model call four tools in whatever order it liked pushed a single webshop question past the context window of a frontier model. The fix was to gather the evidence in code first.

A 4B model edged the GPT-5 family at bargaining. The interesting number is the spread

Microsoft Research says a 4-billion-parameter model trained with SocialRL out-scored GPT-4.1, GPT-5.1 and GPT-5.2 across six bargaining domains. The winning margin is thinner than the method's effect.
