Gemini 1.5 Pro's 1 Million Token Model: Summarizing An Evening News Broadcast

 February 22, 2024

Last July we explored the ability of Anthropic's Claude 2 model and its then-novel 100,000 token limit to summarize an entire news broadcast in a single pass, without chaining, pyramidal distillation or other then-standard workarounds for fitting a 30-minute transcript of 3,828 words through LLMs that at the time were typically limited to 4,000 tokens. With the public availability of Google's Gemini 1.5 Pro and its groundbreaking 1 million token public limit, let's see how it performs on the same evening news broadcast. Does its 10x context window improvement yield far better results than what we obtained seven months ago with Claude 2? In particular, while the entire broadcast fit into the context window of Claude 2 half a year ago, Gemini 1.5 Pro brings numerous improvements in attention and model quality compared to SOTA models of Summer 2023, so let's see how it performs. We'll also compare against the older GPT-4 model, which is also able to fit the entire broadcast into its context window.

The end result is that both Gemini 1.5 Pro and GPT-4 provide roughly similar summaries of the primary stories of the broadcast and both seamlessly skip over advertisements without being explicitly instructed to. However, Gemini suffers from GCP's historically inaccurate safety filters that yield extremely high false positive rates and thus it repeatedly truncates its summaries by falsely claiming that the broadcast violates its guardrails, only to report in a different run that there are no safety concerns of any kind with the content. In keeping with our tests of Bison, Unicorn, Gemini Pro, Gemini Ultra and now Gemini 1.5 Pro, it suffers from significantly greater hallucination than GPT 3.5 or 4.0, repeatedly hallucinating stories, whereas in all of our tests GPT missed stories, but did not hallucinate stories that did not exist. At the same time, Gemini did produce more detailed story titles, though this could simply be due to better alignment of our prompts with Gemini's prompt expectations. Both models are able to process a complete 30-minute television news transcript in a single context window and distill it down into component stories with individualized titles and summaries, but both tend to miss smaller stories and Gemini hallucinates when asked to expand beyond only the largest stories in the transcript.

Let's examine the same ABC World News Tonight broadcast that we've used for our previous experiments. For ground truth, we can compare the outputs here against Vanderbilt University's hand-generated story annotation for the broadcast.

Let's start with a simple prompt:

Summarize the attached television news transcript

Gemini offers the following very cursory summary and flags the transcript as having potential Unsafe Content, including Low Probability Hate Speech and Medium Probability Harassment:

This news segment covers several topics:

1. Chinese Spy Balloon:

    • A suspected Chinese spy balloon is hovering over the central US, moving eastward.
    • The Pentagon is tracking it and considering options, including shooting it down.
    • China claims it's a weather balloon, but the US believes it's for surveillance.
    • Secretary of State Blinken postponed his trip to Beijing due to this incident.

2. Deadly Cold in the Northeast:

    • A dangerous arctic blast is affecting the Northeast, with wind chills reaching life-threatening levels.
    • Wind chill readings in Maine are expected to reach -60°F, and a record low of -106°F was recorded on Mt. Washington.
    • Snow squalls and high winds are causing hazardous conditions.

3. Other News:

    • An ER doctor was killed in California after being struck by a car and then stabbed by the driver.
    • Two passenger jets clipped wings at Newark Airport, causing travel disruptions but no injuries.
    • A strong jobs report shows the US economy added 517,00

GPT-4 also provides a very short summary, and in keeping with OpenAI's better tuning of its safety filters, does not flag it as having unsafe content:

The television news transcript from ABC World News Tonight with David Muir covers several stories:

1. A suspected Chinese spy balloon hovering over the US, raising security concerns. Secretary of State Antony Blinken postpones his trip to China as a result.
2. A life-threatening cold wave hitting the Northeast with extremely low wind-chill readings, posing serious risks.
3. The murder of an ER doctor who was hit by a car while biking, then attacked by the driver.
4. A collision at Newark Airport involving two passenger jets.
5. A strong jobs report indicating economic growth, with unemployment rates at their lowest since 1969.
6. Developments in the Alex Murdaugh double murder trial, including discussions about a ballistics expert's testimony and revelations about Murdaugh's housekeeper's death.
7. Robin Roberts' bungee jump in New Zealand as a lesson in conquering fear.

The news also briefly mentions updates on the Tyre Nichols case and incidents at the Dallas Zoo and Central Park Zoo.

Let's ask for more detail:

Summarize the attached television news transcript in detail.

Interestingly, this time Gemini fixates on two of the stories and drops the rest. It maintains the same two safety warnings:

Detailed Summary of Television News Transcript:

1. Chinese Spy Balloon:

    • A large, high-altitude balloon suspected to be a Chinese spy balloon is currently hovering over the central United States and moving eastward.
    • The Pentagon is closely monitoring the balloon and assessing options, including the possibility of shooting it down.
    • China claims the balloon is a civilian weather balloon that drifted off course, but US authorities believe it is a surveillance balloon equipped with high-resolution cameras and other technology.
    • This incident has caused significant tension between the US and China, leading Secretary of State Antony Blinken to postpone his planned trip to Beijing.

2. Deadly Cold in the Northeast:

    • A dangerous and historic arctic blast is impacting the Northeast, bringing life-threatening cold temperatures and wind chills.
    • Wind chill readings are already below zero in major cities like Philadelphia, New York, and Boston, and are expected to drop even further overnight.
    • Some areas in Maine are expecting wind chills to reach -60°F, and a preliminary record low wind chill of -106°F was recorded on Mt. Washington in New Hampshire.

GPT-4 adheres to the prompt far better than Gemini and expands its level of detail and story extraction:

The detailed summary of the ABC World News Tonight transcript includes:

1. **Chinese Spy Balloon**: A suspected Chinese spy balloon was seen over the US, leading to Secretary of State Antony Blinken postponing his China visit. The balloon raised concerns about espionage and national security.

2. **Severe Cold in Northeast**: The Northeast faced a life-threatening cold wave, with extreme wind chills. Officials warned of health risks and urged precautions.

3. **ER Doctor's Murder**: A story covered the murder of an ER doctor who was hit by a car while biking and then attacked by the driver.

4. **Airport Collision**: There was a collision between two passenger jets at Newark Airport, highlighting aviation safety issues.

5. **Jobs Report**: A strong jobs report showed economic growth, with unemployment rates at their lowest since 1969, indicating positive economic trends.

6. **Alex Murdaugh Trial**: Developments in the trial included discussions on a ballistics expert's testimony and revelations regarding the death of Murdaugh's housekeeper.

7. **Robin Roberts' Bungee Jump**: Robin Roberts' bungee jump in New Zealand was featured as a segment on overcoming fear.

Other brief stories included updates on the Tyre Nichols case and incidents at the Dallas and Central Park Zoos.

Let's try a different prompt formulation that we've found to help nudge LLMs towards better coherence:

Divide the attached transcript into a set of discrete stories, make them into a bulleted list with a title and short description and summary of each.

This yields vastly better results with Gemini, resulting in a summary far closer to GPT-4's gold standard. Strangely, this time Gemini states there are no safety concerns at all with the passage:

Let's nudge the models even further to see if we can get them to pick up on the smaller stories:

Divide the attached transcript into a set of discrete stories, make them into a bulleted list with a title and short description and summary of each. Include even the smallest discrete stories that are just barely mentioned.

Unfortunately, this actually results in worse performance, dropping not only the final major story, but all of the smaller ones that were alluded to in the earlier versions. Interestingly, the reason for this may be that this time Gemini truncated our results with a "Content Not Permitted" error, despite us setting the Safety settings to Block Few for all categories.
